Why does One Piece antagonist disappear after being defeated?
Let me take an instance of one villain: Arlong. Arlong got defeated by Luffy, he wasn't killed. Luffy didn't stay in Kokoyashi village either. So Arlong could have returned to his usual business of enslaving the village. He would have faced ugly humiliating words from Villagers initially, but why would it matter? All you gotta do is gang-up on them. No one in the village was strong enough to stop them.
There are many other pirates who just disappeared after being defeated. It's not like they lived their life with principle or something, they were bad guys who used to loot, cheat, and kill people. Why wouldn't they continue that after being defeated?

Nobody said they didn't? Or am I wrong?

I must admit I do agree with both of the other 2 answers, however i think there is also a simple logical approach to the issue; with each successive antagonist luffy takes on the antagonists get stronger and stronger and so do the protagonists. Some of the antagonists are important and come back into play later on and some of them had 1 purpose, to be the next stepping stone for the straw hats to overcome and once they played that role they have no more use. Also who knows, maybe Arlong rules once again and straw hat is too busy fighting warlords and emperors to even know that Arlong is back in power. Whitebeard kept his islands safe because the threat of his crew hunting down enemies and destroying them but the straw hats are too busy progressing toward One Piece to keep tabs on those they defeat. Even if Arlong is back in power as long as he doesn't chase after Luffy then Luffy and his crew wont find out for years and years as they search for One Piece.

In most of the cases, the big villains we've seen have been arrested by the Marines after they were defeated, so they would not get such an opportunity. We see most of them in the Impel Down arc, locked up.
Specifically, in the case of Arlong that you mentioned:

 It is currently unknown where Arlong is being held, since we didn't see him
 in Impel Down, but he is being held by the Marines somewhere.

it might be because, if pirate defeat another one usually that village will be under control of the winner, for example white beard had alot of villages under his control and no body ever touch them, because other pirates knows that if any thing happened in that village, it will cause them a lot of troubles with white beard and might start a war if the to side are strong.

Why did Angel and Otonashi want to pass on and make others pass on?
The characters think passing on makes them re-incarnate. They are not sure what happens after passing on.
Consider these points on why a sane person would not want to pass on:

You live in a world where you don't die (pass on) as long as you don't attend classes or be a model student. That means you don't need to study unlike in the real world where you are even beaten (happens where I live) or punished by teachers if you don't get good grades. You won't be humiliated by others for being dumb.
You can get superhuman powers just by writing a computer program. You could copy, share and edit programs and probably fly and double jump. You can become a super hero. You can. Deadpool has only regeneration and became a super hero, but in Angel Beats, it's the minimum power you have. What Kanade did was just the tip of the iceberg.
There are computers. You can play video games and program your own. You could create and share videos on sites or social networks like Youtube and Facebook. You can probably integrate websites or software into your powers and automate them. Free internet and computers which is a limited in the real world to the previliged few. Especially not computers which you can use to re-program yourself.
You could reincarnate into something or someone who is way worse off. The characters' lives are not really that unfortunate compared to many in the real world. You could be reborn as a holocaust victim or an activist who is tortured or a young girl in forced prostitution or a terrorist in Guantanamo Bay or a pig raised for meat in a closed cage.
You get free food and every other basic resource you need. You can create everything you want from dust. Consider being born in an impoverished nation during a famine.
You're probably going to lose your memory. Even if they reincarnate into someone like a Rich Kid who is always happy and enjoys his/her life (Which is very less likely in the real world) you'd still lose your memories. People by nature are afraid of memory loss.

They were sent there because they had things "unsolved" in their life. Staying there means they can't solve the thing that disturbs them.

There is no reasonable conception of reincarnation where you could somehow be suddenly thrust into the life of a person imprisoned in Gitmo.

People who find themselves in the Angel Beats afterlife are, necessarily, people whose current lives are unfulfilled. Consider Yui's case: what good would skipping school, or being superhuman, or having a computer do her, if in order to have those things she had to specifically avoid experiencing the simple, mundane things that her quadriplegia in life deprived her of? Point is, the Angel Beats afterlife is specifically designed so that you can only stay in it as long as your life is unfulfilling. Your life, OP, might be hunky-dory, and you might well enjoy the afterlife. (...)

(...) But in that case, you wouldn't end up there in the first place. You'd just go right on to your next reincarnation. For everyone in the SSS, attaining that fulfillment was worth more than free food, or UNLIMITED INTERNET, or whatever other thing you personally see as desirable.

@senshin But what about the fact they may be incarnated into some animal or some one with more pain. And be dragged into the terrible cycle of rebirth.

@senshin The flashback memories are pretty rare. They are happy and enjoying themselves most of the times.

@senshin What about the fact that they are most likely going to have almost infinte unfulfilled lives in the cycle of rebirth. Experience more terrifying and unfulfilled lives.

Perhaps there is a cultural disconnect here. In the Japanese (Buddhist-ish) conception of reincarnation, you don't get to escape the cycle of rebirth; or at least, freedom from the cycle is the ultimate goal of life. It would be narratively absurd if you were freed from the cycle on a mere technicality about how you comport yourself in the afterlife.

@senshin That's what I'm talking about. You get a super powered awesome life with a few very bad memories. Why leave it for pain and uncertainity. Live it as long as you can. As long as you hold those few sad memories you get to laugh and enjoy life with friends.

Angel and Otonashi's actions were not derived from logic, but rather from their beliefs and convictions. They believed that people were not supposed to permanently stay in the afterlife dimension. Their beliefs were probably influenced by their religious/spiritual beliefs from when they were alive.
Their beliefs were supported by evidence in that world. For instance, the way passing on works supported their belief. A person passed on when his/her regrets had been eased. From this and other evidence, it was apparent that the whole purpose of the afterlife dimension was to ease people's regrets and to allow them to be reincarnated, rather than to provide a permanent paradise for them.
Also keep in mind that staying in the afterlife dimension means that a person has to hang on to his/her regrets. This means that anyone who stays there is likely still suffering from his/her past memories, whereas anyone who leaves has made peace with his/her regrets, and can forget them in his/her new life.

The point that they were led by their belif sounds plausible. They could've turned that place into semi-utopia while holding onto a few regrets. I envy them.

I think senshin makes a lot of good points in the comments, but I can also see where you're coming from with this; from a certain perspective, it does seem like it would be better to try and stay in purgatory forever.
I would give two major reasons why the kids decide to pass on anyway, both based on senshin's comments:

It's philosophically, culturally, and narratively necessary that they don't squat in purgatory for all eternity;
They can't really stay there anyway, because the place is constructed as a giant trap for exactly that kind of thinking.

Regarding point 1, think of it this way: in a Christian setting, God would not allow people to just live fantasy lives in purgatory with no intention to pass on. It would go against the philosophy of the Christian religion; in Christianity, either you go to Heaven, or you go to Hell. God sends people to purgatory to give them a second chance at Heaven, and if they don't take it, they go to Hell. The very construction of the universe forbids people from permanently living in purgatory. It's kind of like being someone with no citizenship in any country; purgatory is like an airport, where you can stay for a while but not forever.
Angel Beats uses more of an Eastern-style religious philosophy, but the same idea applies. Who knows what happens to them if they don't take their second chance, but in the Buddhist philosophy, escaping from the cycle of rebirth through some backdoor like remaining permanently in purgatory is just as unfathomable as escaping both Heaven and Hell by the same mechanism would be in Christianity.
This is simultaneously an in-universe and out-of-universe reason. Out of universe, the writers would have written it like this because that's what their cultural background would lead them to. In universe, the characters would want to pass on for the same reason: their culture is telling them that it's unthinkable to just linger in purgatory forever, ignoring their problems. (Since some kind of afterlife explicitly exists in the Angel Beats universe, there probably are safeguards of some kind to prevent permanent squatters in purgatory, but we never see proof of this in the series since no one tries to remain in purgatory with the express purpose of remaining in purgatory.) They do all seem to decide, very quickly and suddenly, that they're ready to face their problems and pass on, but the latter half of the show had all kinds of pacing issues, so I count that more as a writing problem than an actual inconsistency in the universe.
Regarding point 2, it's not only becoming model students that will cause them to pass on; it's becoming fulfilled, in any way that allows them to move past whatever was haunting them. This is abstract enough that it seems like no matter how you tried to avoid it, you would eventually become fulfilled and end up passing on. The SSS didn't because they were purposely holding on to their rage, turning it over and over in their minds, dragged on by the charisma of Yuri. But how long could they have actually stayed like this?
As we saw in Episode 3, all it took to send on Iwasawa was a really great performance. She had no idea it was coming and didn't consciously seek it out at all; she just happened to stumble on something that made up for whatever she'd missed out on in life, and it sent her on. The things we saw send the characters on in the last few episodes probably aren't the only things that would have worked. For each of them, there is most likely a wide spectrum of events that would have caused them to become fulfilled enough to pass on. Even locking yourself in a windowless room might not have been enough to prevent passing on; for all we know, if Yuri had sat in a dark room and thought long enough about what happened to her siblings, she would have eventually come to the same conclusion she reaches towards the end of the series, and would have been contented enough with it to pass on. It's entirely possible that becoming superheroes with all the food and Internet they wanted would be enough to content them and send them on. There are traps everywhere for someone who's trying to enjoy themselves in purgatory without passing on. The only surefire way to stay in purgatory is to stay tormented and miserable, and where's the fun in that?

To end with, I'll address a few of the specific points mentioned in the OP:

"You won't be humiliated by others for being dumb." Yuri does quite a lot of humiliation of the dumb. They don't mind because they like her, but bullying and social ranking can still exist in this world. I guess you can at least settle your differences in a sword fight or gun fight, though, since no one can die. The pleasure of repeatedly stomping down the people bullying you, though karmically a little iffy, might even be enough to send you off into the next life.
"You can become a super hero." Sure, but to what end? There's no one to save and no one to fight. You could have fun leaping around the buildings for a while, until you think "This is so much fun! I love being a superhero!" and then poof, off to your next life.
"You can play video games and program your own. You could create and share videos on sites or social networks like Youtube and Facebook." We don't know how much of an Internet actually exists. There might not even be an Internet; you might be limited to desktop apps that you burn to discs made from dirt. Even if there is, there might not be any Facebook or YouTube, and you'll have to make them yourself. Then you'll feel all satisfied that you recreated YouTube, and then poof, off to the next life. On the other hand, the only operating system available is Macrosoft Winding, which seems to be based on Windows, so using the computer might be a good way to stay angry and miserable so you don't pass on.
"You could reincarnate into something or someone who is way worse off." I actually think this is pretty unlikely. In Buddhist philosophy, what the kids are really doing when they come to terms with their bad memories is getting rid of a negative karmic seed and ridding themselves of an attachment to the physical world. These are good things in Buddhism; they help you reincarnate into a better state and bring you closer to breaking out of the cycle of rebirth. So if anything, they would probably reincarnate into a better life than the one they left. (And the "terrorist in Gitmo" scenario is unlikely because reincarnation in Hinduism and Buddhism starts you as a newborn, so even if you began as a newborn Yemeni villager, you would still have the choice not to be a terrorist.)
"You're probably going to lose your memory." They probably were afraid of this when they chose to pass on. Kanade and Otonashi certainly were, anyway. But the other reasons for passing on were persuasive enough that they overcame this fear.

I think the concept is you need to accept your memories or come at peace with them. Even if you are happy as long as you latch on to those few sad memories or keep beating up normal students you don't pass on. If this is correct all the points that say "You pass on if you enjoy yourself" are invalid.

Also you don't have a choice if you're brainwashed since you're a kid. Most of these terrorists are brainwashed since they are kids into believing that they are doing good and fighting against evil. Even most their "holy books" support that.

@Wally Yes, my last points were somewhat tongue-in-cheek. Nonetheless, look at how little it really took for, e.g. Iwasawa or Yui to pass on: it was mostly an internal process, with very little external action needed. It seems dramatic to us because we see all their memories, so we have a full context for the change, but externally, all they really did was play a concert/get a semi-serious marriage proposal.

As to your second comment, I disagree, but this is not the place to debate the psychology of terrorism.

Lulzed at the Microsoft Windows reference being a Windows hater mysef.

The answers so far gave good reasons why people would not stay there but missed one point I want to add:
People did stay in that world!
The unknown programmer (=other timeline Otonishi?) stayed for eons. The SSS stayed for - who knows - maybe decades, maybe centuries, living almost the life you described. They lived their affections, they played war with their favourite weapons, and they did have their own little Utopia. They just did not know about "Angel Player" and were not able to program the world like you proposed. Kanade on the other hand understood the world as what it was apparently meant to be and tried to help the others to move on (even by force). Otonashi wanted to help people since he lost his sister and so both of them wanted to help the others to move on.
BTW: Almost every one of the SSS did not move on until the shadows came and threatened their bare existence so they had nothing to lose. Plus, it is part of human nature to want catharsis. The only people who really had the choice were the last five, and what should they do after every human and NPC was gone? They had mostly made peace with themselves anyway.
EDIT: Plus it is likely that there are mechanics to repeatedly give people the chance to go on - like the baseball match where the NPCs played exactly the way Hinata needed to remember and make peace with his real life failure.

How did Latias transform in Pokémon Heroes?
In the movie Pokémon Heroes Latias is able to transform into Bianca (a human character in the movie). Serebii.net, however, does not list transform as a move Latias can use. Were any comments made in the movie regarding the transformation? Is Latias using the move transform or is it using some other power?

According to Bulbapedia, in the Pokémon Adventures manga, Latias is also able to appear as a human by using its ability to refract light. This is consistent with its Pokédex entry in the Sapphire game:

The POKéMON enfolds its body with its down and refracts light to alter its appearance.

Latias transformed into bianca because she was bianca best friend so she transformed into her giving him opportunity to hug ash.but at the end if this movie it was bianca even the writer said she did not talked to confuse ash just kiss and ran away

Citing or providing a relevant quote from the writer would greatly improve your answer.

What breed is Enek?
What breed is Norah's sheepdog, Enek? I was looking at sheepdog breeds at https://en.wikipedia.org/wiki/Sheep_dog and thought he sort of looks like a Border Collie, but I'm not sure.

Edit: After reviewing Enek's first appearance in the second volume, I don't believe that Enek's breed is explicitly stated. As such, it could be difficult to identify Enek's breed just by his appearance. In lieu of any official information, an answer based on Enek's physical traits and information pertaining to prevalence of sheepdog in medieval Europe would be acceptable. I am including some links to references that I have been reviewing.

History of Herding at bsca.info
Herding Sheepdogs at janedogs.com
Medieval Dog Breeds at medievaldogs.wikispaces.com
Dutch Shepherd Wikipedia Page
 Belgian Shepherd Wikipedia Page

there is no information about it on the wiki, However Enek does seem like a Border Collie going by the fur and ear patterns.

Unless it's explicitly stated in the novels (and I don't think it is), it might be difficult or impossible to know for sure what breed Enek is. I think the erect ears, fluffy tail, fur thickness, and height of the legs do match the Border Collie. It's probable that a case can be made for a different breed though.

@ShayminGratitude As the asker of the question, you can define how definite you want the answer to be. If the breed was never mentioned in the anime or novels, you can state that you'll accept an informed guess based on evidence; this is very frequent over on SF&F. You can also self-answer, if you find an answer that satisfies you in your own research.

According to http://medievaldogs.wikispaces.com/Medieval+Dog+Breeds:

While many of today's dog breeds can be traced back to the Middle Ages (and some even older), breeds as we know them today, carefully defined by physical appearance, did not exist in the Middle Ages and Renaissance. Instead, dogs were classified by function.

Based on this, it is possible that Enek does not belong to a definite dog breed at all and instead belongs to a breed from which today's breeds are derived. In the books, he is only ever referred to as a sheepdog, and this is consistent with medieval people classifying dogs by function.
As mentioned in the question, Enek shares some traits that could associate him with Border Collies. His fluffy tail, erect ears, fur thickness and coloring, and leg length are consistent with the Border Collie breed. Enek displays a high level of intelligence in volume 13 (though this could just be attributed to personification), and according to https://en.wikipedia.org/wiki/Border_Collie,  the Border Collie "is widely considered to be the most intelligent dog breed".
On the other hand, Enek's physical characteristics could also belong to a Dutch Shepherd. All the physical traits still match. The problem is that Enek is a cartoon and thus his traits are too indistinct to make a definite match.
In conclusion, there isn't enough information available to definitively determine Enek's breed. He could be an ancestor of the Dutch Shepherd, Border Collie, or some other herding dog.

Do the words used to transform into a Magical Garment Girl actually mean anything?
In Kore Wa Zombie Desu Ka (Is This A Zombie?), whenever one wants to transform into a magical girl, he says the following words:

Nomobuyo, Oshi, Hashitawa, Dokeda, Gunmicha, De, Ribura!

Do those words have any real meaning?

Reading this backwards (in Japanese, so by reversing the morae rather than the romanized letters) gives you "raburii de chaamingu dakedo watashi wa shi wo yobu mono" (ラブリーでチャーミングだけど私は死を呼ぶもの), which means "lovely and charming though I am, I am he who summons death".

Why is this person still alive in the ending?
I just finished watching Psycho Pass 2, an was wondering why Kamui Kirito is shown in the ending, sitting inside an isolation chamber?
It's clearly shown how Sakuya Togane and Kamui shoot each other: Kamui is getting a direct hit, and Togane loses his arm resulting in his death a few minutes later. I don't get how Kamui should have survived this...

Kamui Kirito is dead.
The image you posted from the ED of episode 11 is of Mizue Shisui, the inspector that Kamui kidnaps.

She is usually seen with an eyepatch over here left eye. The eye that she's covering is the eye that Kamui used to wield the dominators.

oh lol, you are right :D

Will Boruto be able to awaken Byakugan?
As Himawari was able to awaken Byakugan, is it possible that Boruto will also be able to use it?
I am in doubt because, if we take the Uchiha family as an example, then every member of their family has the ability to use Sharingan. I would guess this also applies to the Byakugan users.
Sasuke's child Sarada also awakened her Sharingan even though Sakura was not a Sharingan user.
So in that case, is it possible that Boruto will be able to use the Byakugan in the future? If not, then does it have something to do with genes?

Yes, it does have to do with genes. Visual techniques such as the Sharingan and Byakugan are passed down genetically.

First off, no one except Kishi sensei knows what it's going to be for Boruto and Borutoverse. That said, we can only guess what's going to happen. Secondly, since this is the Naruto series, IMO, it would be highly unlikely that Boruto would gain the Byakugan. Because that would make him kind of excess powered.

I think now even Boruto possesses a Byakugan. (Boruto: Naruto next generations)

@SahanDeSilva We know Boruto possesses something, but we don't yet know what it is. Its not an ordinary Byakugan. The black sclera and cyan Iris with no veins around the eye are not traits of a Byakugan. No one else having ever seen it also is suspicious, though it could just be a lot of coincidences that prevent anyone from seeing his eye.

@Ryan I watched the last episode of Boruto. It seems like Boruto possesses something similar to 'Tenseigan'. I wonder if it could happen.. (Still not confirmed though)

Yea, it is similar to that but still the powers of that eye is not confirmed. Never saw this coming that Boruto series will also come. Maybe the answer for this question will come later in much detail which might tell us more about the powers of Boruto eyes.

From trivia here, it is stated that Masashi Khisimoto forgot to give Byakugan to Boruto and Himawari.

Boruto and Himawari Uzumaki, despite being children of Hinata Hyūga,
  do not have the characteristic white eyes inherited by Hyūga
  descendants.  According to Masashi Kishimoto, he simply forgot to give
  it to them.

Later he corrected this. But so far, only Himawari has Byakugan.

Kishimoto later corrected his mistake for Himawari by giving her the
  Byakugan in the Zai no Sho's special chapter The Day Naruto Became
  Hokage.  While activated, her eyes take on the normal characteristics
  of the dōjutsu. When not in use, she has her original blue eyes.

OK, so if any of you have been watching Boruto Next Generations, you already know that Boruto has the Byakugan, since when he's fighting with Kawaki in episode 1, he uses it. Now it's a different thing that he might have it implanted, but when it flashbacks to his academy days, he has the byakugan shadow already, since it has appeared numerous times, first with Denki, then with Metal Lee. So yes, I think the answer is, he will get byakugan, whether just a shadow or implanted.

that is not Byakugan. that is described to be an unawakened form of Tenseigan

The eye that Boruto has is clearly not a Byakugan, and everyone can agree, what I find it most likely is a new Dojutsu, no one from the Byakugan family ever married someone with as much chakra as Naruto has, unless you count the grand-son of Kaguya (the dude inside the moon) which already had the Byakugan with an extreme chakra source.
Another option would be the mix of the byakugan with a descendant of the sage of the six paths, but this is denied by the fact that Kaguya never had an eye like that manifested, while she is the original blood of any jutsu, as the creator of the series just said that he forgot to give them Byakugans he may have thought to give Boruto something different, Naruto isn't part of the byakugan bloodline so off-springs that don't have the byakugan are totally possible, the "theory" I like the most is the mix between the Uzumaki genes (the Uzumaki clan) with the Byakugan and the blood of the sage of the six paths, there is no recorded or shown eyes like Boruto's, so a bit of diversity could've been expected from the creator.
Although this looks like a continuation of the Naruto series, it's not really. If you're someone that never watched Naruto you can live happily ever after and have no need to watch it to watch the Boruto series, and even if this was the Byakugan that Boruto inherited it would most likely wouldn't make him have excessive power, he is Naruto's son, not Naruto himself, so he doesn't have the nine tails, and for sure not that much chakra as he has.

I don't think think it's likely that boruto will get the byakugan because as you can see in the manga and the anime that he has a new dōjutsu be as in the anime he could see chakra points but he could also open a portal with his new dōjutsu and the byakugan can see chakra points and the rinnegan can open portals so I say borutos prowess is stronger and better than a byakugan and sharingan so it's unlikely from him to have two dōjutsu

I think being the Naruto series wanting to give Boruto something special, his eye may have been somewhat an evolved type of Byakugan. Being a son of Naruto, someone who has ninetails inside of him that made him special. I think same goes to Boruto.

Boruto cannot use the byakugan in the anime Boruto Next Generations he has what is called Dōjutsu and its only in his right eye. He may obtain it later but seeing as the byakugan is typically in bothe eyes, Dōjutsu is in only one

The Byakugan is Dōjutsu, an Eye Technique. saying that Boruto don't have the byakugan because he has Dōjutsu in general is very inaccurate because his mother Hinata has Dōjutsu too and if Boruto was to the Byakugan it would be from his mother

Is Akamaru a pet or a comrade?
My question is if Akamaru is a pet or a comrade to Kiba. I'm wondering this because he fights alongside Kiba and Kiba treats him like he was another human being (most of the time), but at the same time he also treats him like a pet.
Examples and or clues that he's a pet:

Teaches him tricks
Takes baths with him (not a lot of people do but a lot of little kids do)
Calls him "boy" (Like, "Here boy!")
He was given to Kiba at a very young age by Kiba's mother (something that happens a lot in real life)
They lived together for (you could say) their whole life so they're like family (something that also happens in real life)
They play together (something you will do with a friend or pet)
Kiba cares a lot about Akamaru that he will do anything to protect him (something that a lot of people do for their pets)

The list goes on and on. I've been looking up stuff, but haven't found anything that says he's his pet. It only says he's his partner, comrade, friend, etc.
When I look up, "Kiba and his pet", then go to images, it shows (at least the first couple of pictures) Kiba and Akamaru.
So is Akamaru Kiba's pet or comrade? To better put it, is Akamaru a pet or a comrade to Kiba?

why not both pet and comrade?

@MichaelMcQuade he could be both, but I'm wondering if he is a pet or a comrade to Kiba.

The meaning for pet and companion is pretty close but since his dog is with him from his childhood then I guess it already become a part of his life. So I guess he treats him like a comrade who works together and treats him like a pet at home when he needs care or attention. Even in naruto shippuden episode there was one event in fillers when kiba dream that he has become hokage and he announced that there must be one dog day and everyone must own one dog. Since they cant buy comrade (talented dogs) so he might be indicating to own one pet dog.

He is Kiba Inuzuka's partner, as well as his best friend and companion - Naruto Wikia

Akamaru is a Ninja Tool no matter how cruel that sound. If he is a pet/comrade then Kiba won't be allowed to use him in Chuunin Exam . . .

What about after the first few images? kekeke

I believe this will depend on how you define a pet and comrade, dictionary.com defines a pet as any domesticated or tamed animal that is kept as a companion and cared for affectionately. And it defines a comrade as a companion who shares one's activities or is a fellow member of an organization/a fellow soldier or member of the armed services.
By the first definition he could be considered a pet, though he is clearly more than that. The entire clan use collaboration techniques with their canine companions, drawing strength from their combined and coordinated techniques; they have a symbiotic relationship on and off the battlefield, protecting each other and playing together, as well as fighting fiercely together.
In the real world hunting dogs are probably the closest comparison we have to the battlefield interactions we see between the Inuzuka clan and their companion animals. Training a hunting dog requires asserting yourself as an alpha in their pack, and maintaining that controlling position constantly. Treating a hunting dog as a pet as well frequently blurs the lines on what behavior is and is not allowed from the animal and can undermine its hunting training.
https://www.southernstates.com/articles/training-hunting-dogs.aspx
In the case of the Inuzuka clan we see more than just a working relationship that leads to optimal performance of hunting dogs. Akamaru makes suggestions during fights. He even bites Kiba in the fight against Sakon and Ukon insisting that they use a risky technique. This clearly indicates that Kiba is not an alpha to be obeyed regardless of circumstances and they have a more equal relationship more akin to sworn brothers.
In conclusion, Akamaru is more than just a pet and its probably most accurate to call them true partners.

Is Akamaru a pet or a comrade?
That's the question and my answer to that...
Well in my limited knowledge about it I say that Akamaru is not just a pet to Kiba, but more as a comrade/friend/family. When you watch Naruto, in some of their scenes you will see no pet-to-master relationship but a bond of friendship between them like comrades. You will see that Kiba treats Akamaru more than just a dog or a pet, but treats it like a comrade that he wants to protect and cherish... ^__^

would devil fruit users be affected in fresh water
The sea stone, which is the weakness of devil fruit users, was said to have the same power as the ocean, and it was said that the sea rejected the devil fruit users. I understand that devil fruit users can't swim, but if they were standing in a river or fresh water of any sort, would they still lose all their strength and be unable to do anything?
I tried to search for it, but they closed it and archived it, so can anyone help please?

i don't think fresh water affects them as it was keeping himself covered in water which was Luffy's plan to defeat Crocodile

According to wiki there is a nice explanation about weakness of Devil fruit. I would like to highlight few points which might help you.

Oda stated in an SBS that Devil Fruit users are susceptible to all
types of water, not just seawater.
This includes the white sea surrounding Skypiea. He elaborated on
this, saying that "moving" water, like rain or waves, does not weaken
Devil Fruit users, while standing water does. This was also shown
first when Monkey D. Luffy was in the Dance-Powder induced rain and
did not feel his power slipping away, and again when on Zou, the sea
water that Zunisha used to shower did not affect him despite being sea
water as it was "moving" water.

So the main conclusion which is given in wiki that:
Devil Fruit user will not be restricted in the water if he or she is not physically touching the water.
So according to me it might affect as long as devil fruit users are physically touching them.

Luffy and Brook losing strength as a result of being submerged in water.

i understand but what i meant was say if luffy was standing in a river up to his waist, would he become weak? Because the water is flowing but it's not deep enough to drown. so would he still be able to play around, or would he just loose all of his strength?

@Dragon See edit... The scenario is complete similar to what you just said. And conclusion: Yes they will loose strength

then again, in the scene where luffy dropped down into the bathroom of bon hancock while she's having a shower, but neither of them are paralysed, would it be that the amount of strength lost depending on the level of water?

What is the highest-level monster card in the Yu-Gi-Oh anime?
I'm a long time Yu-Gi-Oh fan, and I wanna know, what is the Yu-Gi-Oh monster card that has the highest level (currently). Basically, I mean the highest amount of stars on the top of the card.
Basically in the Yu-Gi-Oh anime, each monster card has a level number (the amount of stars at the top of the card), and I want to know which monster card has the highest level.
Example:

An alternate answer to Senshin's answer is however the Fortune Ladies used by Carly Carmine while she was a Dark Signer in the Yu-Gi-Oh! 5D's series. and unlike her Fortune Fairies she used before becoming a Dark Signer the Fortune Ladies are also official cards
while the starting level of the Fortune Ladies is initially low, the highest being 6, their special ability allows them to gain a level every turn which in turn affects their ATK and DEF.
so Fortune Lady Earth which has the highest initial Level of 6 needs only 6 turns to reach Level 12 which is indicated to be the max their special ability will allow them to go up.
Also Fortune Lady Earth and Fortune Lady Dark have the higher multiple for their ATK and DEF out of the Fortune Ladies being 400 which means 400 x 12 = 4800 ATK and DEF which beats all 12 Star Monsters except 3 who's ATK and/or DEF is 5000 but this can be supplemented with spells and traps. with their much lower tribute cost they are quicker to summon especially Earth who's initial 2400 ATK/DEF is close to the 7 star Dark Magician's who requires 2 tributes instead of Earth's single tribute.
their natural flaw is however the fact that they take some time to get powerful unless you use other cards to boost their level. also their special ability stop at Level 12 which means getting them to Level 12 quicker via other cards wont give them as high of a level as if one waited and used the cards afterwards

In the OCG and TCG, monsters cannot have a Level lower than 1, but card effects can freely raise a monster's Level to arbitrarily large values in excess of 12.

Source: Level
depending on how one plays this wait can be problematic. some strategies which could work is to prevent summoning and use Swords of Revealing Light to stop attacks for 3 turns each until a Fortune Lady has enough ATK/DEF to shrug off most attacks
Fortune Ladies

Remember that Kaiba vs. Yugi duel way back in Duelist Kingdom (episodes 22-24) where Yugi polymerized his Mammoth Graveyard with Kaiba's Blue-Eyes Ultimate Dragon? (lol)
Blue-Eyes Ultimate Dragon is a level-12 monster. I don't believe there are any monsters of level 13 or higher. So, there's that. (There are probably other level-12 monsters in the anime, too; a fair number of the monsters on this list seem to show up at one time or another.)

Years later, thanks to Yu-Gi-Oh! ZEXAL and powercreep being a thing we now have multiple official level 13 card in the anime.
New Order 13: Etheric Amon

Appears in episode 120/121 of the show. Has no real TCG card equivalent.
Number iC1000: Numeronius Numeronia

Appears in episode 140/141 of the show. An actual real world version of the card exists.

I don't remember seeing any specific instance of monsters having an original level higher than 12 in the anime, and I'm not sure for a particular instance of a highest shown level however:

Some monsters have a ??? or ? level. Sometimes this is because the original level was never revealed; other times it has an effect that derives level from gamestate like some real-world cards do with ATK and DEF (but never level). Some may be implied to be inherently infinite. Super Fusion God has a level of ??? and is a fusion of one monster of each level 1 to 12.
There are some level 0 monsters in 5D's (and, funnily enough, these exist in real cards too!) thanks to the Synchro and Negative/Dark Synchro mechanics.
In ZEXAL, Xyz monsters are introduced, which have ranks rather than levels. They are quite comparable. "New Order 13: Etheric Amon" and "Number iC1000: Numeronius Numeronia" are rank 13. Like the above point, there are also rank 0 cards.
With card effects, any card can have an arbitrarily high level. With looping, any level can be achieved. Level changing is an important mechanic is 5D's, ZEXAL and Arc-V for the Synchro and Xyz mechanics. Some cards like the "F.A. Archetype", "Fortune Lady", and "Dark Strike Fighter" have effects based on levels. With a small number of cards, a ridiculously high novel level can be achieved using level lifter on two monsters of the same type with less than 1000 ATK/DEF, discarding a high-level monster (at best, level 12 like "Yubel the Ultimate Nightmare" for example) thus making them both level 12. Then use "Tannhauser Gate", making both monsters' levels the sum of them: after one use we now have 2 level 24 monsters. Using a second "Tannhauser Gate" gets then up to 48 and a third gets them to 96. For now, we will ignore loops which might make it semi-redundant. Supposing you have "Dark Strike Fighter" and two suitable monsters (same level, >1000 ATK/DEF), use 2 copies of "Tannhauser Gate" and you will be able to drop an opponent from 8000 (or up to 9600) life points to 0 with one use "Dark Strike Fighter"'s effect!

I believe it's this- supreme king dragon black zarc. Only level 13 I've ever seen.

can you provide a source of this card being official? when i google that name the only reference to that exact name is this Pintrest page while the closest i get is Supreme King Z-ARC which is 12 Stars and also given their same image, the card you show has some odd graphic artifacts that the other card doesn't have, namely the blue areas

Using the yu-gi-oh card database, I can confirm that there is no such named card as you can see for your self as well

Did Kakashi actually invent the Chidori?
In the newest filler episodes of Naruto (462 and 465), they show Hagoromo and Indra using some sort of lightning release that looks like the Chidori. So did Kakashi actually invent it? Or did he copy that technique just like all his other attacks and claim it as his own?

Your first sentence already answer the question. It was a filler, a non-canon, thus you can't use it as a base of asking whether Kakashi was the inventor or not.

Here's the referendum from wiki:

The Chidori was created by Kakashi Hatake after he failed to apply his lightning-nature to the Rasengan

Maybe in the said episodes the ninja uses a variant of "Chidori".
There are various altercations of Chidori that visually looks "similar", e.g. Raikiri.
So I guess what I am saying is, even though "that" particular form of chakra behaviour exists, it is possible (and canon) that Kakashi is in fact the one who invented Chidori.
It is very possible in Naruto-verse to invent a new jutsu even if they haven't been taught down the generations. But as canon goes, till this date, Kakashi is said to be the inventor of Chidori.

Also to note: Since they are fillers, it could be (Or rather is) made up, and shouldn't be paid attention to.

AFAIK Chidori is Raikiri and Raikiri is Chidori. It's just the naming, but they actually are the same jutsu. Raikiri is the name Kakashi used for the jutsu. Chidori is the other name of the jutsu given by others based on how it makes noise like that of a thousand bird squeaks.

I mean, it was basically just added into the show because Studio Perriot wanted to show the whole reincarnation thing with Sasuke.
For an in-universe explanation though, it's probably just a case of Kakashi "inventing" something that he didn't even know was already a thing, hence why Indra uses the same handsigns and it makes the same noise.
Ever thought of a great idea, only to find out it's been done before? Same thing.

An earlier question accurately cites the origin of the technique.

What does Shouko say to Ishida on the bridge in chapter 54?
What did Shouko sign to Shouya in Koe No Katachi volume 7, chapter 54?
Note:  the below images are the signs that she used, in the order that they appear (right to left).

I have koe no katachi physical edition ( all the 7 volume ) , but it's indonesian translation. And I don't know if i have to take a picture of the page that I wanted to mention it And I don't have any acces to digital licensed English site like chrunchyol and such as, and thats the reason why I used image from pirate d site. Sorry, and thanks for the image @Makoto

In the anime version Shouko talks about the accident happened because she couldn't change, so she thought it would be better if she was gone and asks for forgiveness. (Won't post it as an answer, as there might be differences between the manga and the anime)

So I watched the limited theatrical release today.  While I can't say that I recall anything verbatim, I'll be updating my answer from here.
Shouko says, not signs, in the movie, that

 She believed that if she weren't around anymore, everything would be better, which is what led her to attempt suicide in the first place.

This tears into the heart of the matter:  the immense guilt and discomfort that Shouko feels about the entire situation, which is what led her to make that decision.
Also, this highlights a point in which the film diverges from the manga, so take this with a grain of salt.

While I can't interpret JSL very well, we can infer what happened through the use of context clues a few chapters earlier.

 This happened after Shoya effectively saved Shouko's life, when she attempted to jump off her balcony into the river below.  Recall in an earlier chapter, Shouko and Shoya swapped positions, effectively keeping her on the balcony, and him plummeting to the water below.

From that, what we can infer is...

 Shouko thought that Shoya was dead, and was feeling incredibly remorseful for attempting suicide, and that Shoya had been badly injured due to her actions.  She's frantically apologizing and is grateful that he's alive.

I'd encourage one to read through the context of the manga several times, too.  In this example, since I reread it, there's little missing from context or from interpretation.

I found a good sources to answer this question
These are from the chapter 54, page 9,10,and 11.
Page 9, third panel.

When did Kastro dirty himself with blood?
In episode 32 of Hunter x Hunter (2011), “A x Surprising x Win”, Hisoka can distinguish Kastro from his double because the original (left) had a blood stain on his chest that was not reproduced by the double-creation technique.

But when did he acquire it? I can’t find the moment in which he would have gotten the stain. It just appears when it’s convenient to the plot.

According to the manga (chapter 54), that wasn’t blood, but “grime that builds up during combat”. So in the anime it was probably a case of the animators not wanting to waste time and resources on representing that before it was needed.

How is it that non reliable mangakas get work again and again?
I've seen it time and again that a mangaka just stops what he/she is doing as he / she loses interest and starts the next project instead.
A very big example includes here "Candidate for Goddess". The Mangaka who created it was and is known for doing that time and again.
What really surprises me is that they just get work again and again despite their tendencies (and they even being KNOWN for that). In other branches (programmers as example) you are a goner from the market when you start doing that.
So my question here is is there any infos available on WHY Mangakas who are known for not finishing their work and instead starting something anew get work again and again seemingly very easily?
(is it something cultural I'm overlooking here, or is it something else at work here?)

Yah, a manga artist will get more work if their previous work sells. Also, given the nature of comic books, published as weekly and monthly serials, it wouldn't surprise if most readers don't actually manage read a series from start to finish.

I feel like part of the reason stems from how a mangaka's job is different from a programmer's job, but I'm having trouble putting it to words so I'm leaving this only as a short comment.

@Maroon I'd say it's because a manga is much more an expression of who the author is than a program. If you need a program that produces some business reports, there are probably thousands of programmers capable of producing it, but each manga, no matter how trite, could only be created by that person. And for a manga to make money, it has to connect with thousands or millions of people on an emotional level. It's much harder to find someone who can reliably make that happen than it is to find someone who can write a program that creates the business report you want.

Business-wise, that is not very important because as long as these mangaka still sells, publishing companies would still like to sign a deal with them. To stop these kinds of mangaka from keep having jobs, then the market must reject their new project. Only then would a publishing company be unwilling to sign them.
Now, most readers are just casual readers. They just read when they like it and are not that attached to a series very much. Only hardcore fans would follow and know everything about a series. Thus for most reader, whether this mangaka is known for being such a person is not very important.
In fact many don't bother knowing who the mangaka is. My sister, who is not an otaku although she ocassionally read manga, knows Naruto, Fairy Tail, Bleach, One Piece, and many other mangas. But if you tell her Masashi Kishimoto, Hiro Mashima, Kubo Tite, Oda, then she'll say, "who's that?" The only mangaka she knows is Fujiko F. Fujio (because it's Doraemon). What they need to know is just the title of the manga and whether it is interesting or not.

In all honesty....I feared that that would be the answer....guess I had hoped for more from humanity^^

@Thomas Well, finding a popular mangaka is much harder than finding a serviceable programmer. Popular works become popular because they create this weird stew of originality, cliche, reappropriation, genre convention, and subversion of genre convention that all come together to create an alchemical reaction with the zeitgeist of an audience. There's so many variables involved that reason can't even encompass it. Manga magazines publish and cancel dozens of manga for every one that succeeds even modestly. It's not that surprising that they'd keep going back to the ones that succeeded before.

What are the similarities between Gol D. Roger and Monkey D. Luffy? Are they related by blood? What are their relatives' ages?
This question is regarding One Piece.
I have three questions to ask. Since they are interrelated, I'm asking them as a single question on this site.

As I was reading about the prominent people in the One Piece universe, I came across Roger's page. It has been mentioned there and in many other places that Luffy is quite similar to Roger in character. Theories on some forums have gone so far as to state that Luffy is Roger's reincarnation. So,
1. Could anyone list ALL the similarities between Roger and Luffy?
This question might seem too broad and ambiguous, but when I say similarity, what I'm mostly referring to is

A common something that the two share
An instance where Luffy says or does something that reminds someone of Roger
Parallel life events

I came across this video and this link that cover a few of them. I'll post the relevant ones here.

A common something that the two share:

Will of D
Gol D. Roger
Monkey D. Luffy
The Straw Hat

In the manga and anime One Piece, Monkey D. Luffy's straw hat is the
  main symbol of the entire series and is the origin of his nickname
  "Straw Hat Luffy."
Much later, during the Straw Hat Pirates' departure for Fishman
  Island, it was revealed by Silvers Rayleigh that this straw hat
  originally belonged to Gol D. Roger.

Both can hear Sea Kings

Besides the Mermaid of legend, the only other people who seem to be
  able to hear the Sea King have been Monkey D. Luffy and Gol D. Roger.
  The latter was said to be able to "hear the voice of all things".

Both their first mates have a scar over one eye
This is probably pure coincidence, or not.
Silvers Rayleigh
Roronoa Zoro
Both are from East Blue(?)

Loguetown, the city in the East Blue located closest to the Grand
  Line, was the birthplace of the late Pirate King, Gol D. Roger.
Dawn Island: home island of Monkey D. Luffy, where he was raised in
  the peaceful Foosha Village and where he trained on Mt. Colubo.

It is mentioned that Dawn Island is Luffy's home island, but is it mentioned anywhere that he was born there?
The Supernova title(?)
Luffy is a Super Rookie, but was Roger one?
In the video link above, Brook says

Gold Roger? There might have been a rookie by that name, or maybe
  there wasn't...

Is there any solid proof that Roger was a rookie?

Instances where Luffy says or does something that reminds someone of Roger:

Luffy's smile when Buggy tries to execute him reminds Smoker of Roger

Smoker saw the smile Luffy gave off to mirror that of Gol D. Roger's
  twenty-two years ago, and considered Luffy to be a potential danger to
  the world.

Luffy's answer to Rayleigh when he's asked how he intends to conquer the Grand Line

Luffy replied that he does not really intend to conquer it, but that
  the person with the most freedom in the ocean would be the Pirate
  King. This brought a smile to Rayleigh's and Shakky's faces, seeing
  the unmistakable likeness to Roger in Luffy just as Shanks saw.

Luffy's words to Raoul that he will be the next Pirate King

He was deeply shocked at hearing Luffy saying he will be the next
  Pirate King and noted that the young boy was similar to Roger in his
  presence.

Parallel life events:

The first person that Roger and Luffy ask to join them on their journey refuses to do so, but eventually accept the offer. Coincidentally, that person also become their crew's first mate.
Rayleigh:

At first Rayleigh declined, but some time later, he formed a bond with
  Roger and became his first mate.

Zoro:

Luffy asked Zoro to join him but he flatly refused to become a pirate. Refusing to die, Zoro accepted Luffy's invitation and revealed his unique fighting style.

Could anyone list other similarities and when doing so, state where the similarity is mentioned: manga, anime or both? Also, could you prove or disprove the East Blue and Supernova cases?

The similarities could just mean that the two are extremely like-minded individuals or it could mean that they are related.
While in prison, Roger asks Garp to take care of his unborn son, Ace. From this, it is obvious that there's a strong bond between the two. Is the relationship based only on deep trust or are the Gol and Monkey families related? Basically,
2. Is Roger related by blood to Garp, and in turn, to Luffy?
A search on the web doesn't yield much, but from threads like this, this and this, a few likely possibilities(barring all supernatural theories) are:

Roger is Garp's brother or brother-in-law.
Roger is Garp's son or son-in-law.

If the relationship had been revealed explicitly, Wikipedia and Wikia would have the answer. Since it's not, has it ever been implied indirectly, anywhere in the manga/anime that Roger and Luffy are blood relatives?

Since the answer to the above question might possibly be 'no' (at least for the time being), the ages of the people involved will be helpful pointers to accord with or negate theories about how Roger and Luffy could be related, to form one's own theories, or to refute the very idea that they are related. As of now, only Luffy's and Ace's ages are known, which leads to my third question,
3. What are Garp's, Roger's, Rouge's and Dragon's ages?
As with the second question, there's no answer in any online encyclopedia.
But some statements found on the Wikia pages are:

Thirty years ago, he* fought Chinjao and earned his hatred after denting his pointy head and robbing him of the means to acquire
  a certain treasure.
It would seem that he** had been around for some time, considering that Brook refers to him as a rookie, more than 50 years
  before the current storyline.
Twelve years before the current storyline, Dragon returned to his home in the Goa Kingdom and witnessed the burning of the Gray
  Terminal.

*Garp
**Roger
Have there been other time related statements in the manga/anime in relation to these four people that could be used to make a rough estimate of their ages?

My apologies regarding the lengthy question.I put in all the facts that I know so that if anyone answers this question, the things I already know will be skipped. A hardcore One Piece fan will probably be able to answer. Also, my knowledge about the series is mostly limited to the Wikia and Wikipedia pages.

I agree that the first and the second question are related, but you might want to post the third question as a separate one, because I don't see the relation between it and the other two.

Since I don't know if Roger and Luffy are blood related or not, I wanna know their approx. ages so that I can form my own fan theories about them :D Thank you for mentioning it, I'll change it into a separate question if others feel the same.Meanwhile, I'll edit the question so that it makes more sense :)

Related Question: what does the D stand for in all the names

@Dimitri mx: Thanks, but how are they related? I don't wanna know what the D stands for..

Luffy is Roger reincarnation :v

1. You answered question yourself.
2. No, they are not related. As Garp hunts Roger across the sea and visits him in prison as an old rival and not as a relative, it is safe to say that they are not relatives. I am not sure when but I think when Aces story is told, it says that Roger asked Garp - because of the 'D.' - to save his son (Ace) from the marine trying to kill all relatives that may have Roger's talent to make trouble.
This again shows that there is no known close relative alive. They are however related in some way because the 'D.' is passed from one generation to the other and it is likely that there were one family or (less likely) people with the 'D.'. That is the closest we can be sure and the closest that is likely if we want to speculate - what is not the purpose of this site.
3.
The Ages of the ones carrying the 'Will of D.' can be found here:

Luffy: 19 Dragon: unkknown Garp: 78 Roger: would be 77
  now Rouge: unknown Ace: would be 22 now

My long post elaborating the first two questions was meant to make people not repeat the same answers again. If you're really thorough with the One Piece universe and can confirm that there are no other additions at all, please inform me, I will select your answer and close this question. The answers cannot be found in websites AFAIK, only a person who knows the story perfectly can answer this I think.

A fandom of this scale can never be fully explored even when we hit the end of the story we can't say for sure that we have all similarities. But I edited my answer to include something to #2.

Could Roger and Luffy's mother be siblings. Luffy's mother is likely deceased. She may have had that similar disease that Roger died from. If they are related, it would explain why Dragon was present for Roger's death. It would explain why Luffy has alot of similarities with Roger why Garp had a personal relationship with Roger, why Raleigh felt a connection with Luffy. That would make Luffy and Ace cousins or brothers using Hyuga Clan logic.

theories and speculation are not proper answers, OP is asking for facts stated in the series that could back-up said claims.

What are the differences between the two personalities of Seijūrō Akashi?
In Kuroko no Basket, the captain of Teiko Middle School and Rakuzan High is revealed to have a split personality. His original personality is shown to be that of a team player: likable and helpful to others. In his final year he suppressed this personality during his 1v1 match vs Murasakibara and awakened his special ability, Emperor Eye.
Midorima and Kuroko in particular note the personality changes in Akashi. The most obvious I can find is that the new personality refers to people by their first names i.e. Kuroko as Tetsuya, Midorima as Shintaro.
Are there any other changes between the two personalities?

Akashi Seijuurou has a split personality, we'll call the first personality "Boku" and the second personality "Ore".
"Boku" is mainly the personality that was shown in the first few Teiko years and also sometime during the Rakuzan-Seirin game. "Ore" was seen after his one-on-one with Murasakibara until the Rakuzan-Seirin game and also a bit in the Vorpal Swords-Jabberwocks game.
"Boku" is generally more caring until Aomine called Akashi "nagging mother". Honestly, I'd say that "Boku" kind of has an inferiority complex because he seems more humble and he admits in Teiko that everyone was becoming better than him. He also admits that he has a weakness of fearing being left behind (as pointed out by Ore during their mental talks). "Ore" on the other hand, has a superiority complex. He says that people should "lower their head" and that he is "absolute" and he is constantly so sure that he will always win. He calls people by their given name which is not really disrespectful or shows signs of superiority or anything but it's just more respectful to use the last names.
Another clear sign (in the anime) is that "Boku"'s eyes are both red while "Ore"'s eyes ahs the right one red and the left one yellow. It's not very noticeable in the manga. "Boku" also focuses a lot on team play while "Ore" focuses more on winning no matter what. This is why "Boku" can do things like perfect-rhythm-plays and gets not only him but his other teammates into the zone as well while "Ore" gets into the zone by abandoning all hope for his teammates.
There are a lot of differences between the two personalities for the plays he makes. Of the two, it is said that "Boku" is stronger. However, both "Boku" and "Ore" were not strong enough to stop Nash and his Belial Eye and to defeat him, "Ore" had to disappear and transfer his abilities to "Boku" in order for the Emperor Eye to be complete. It's rather sad but... yeah.

As far as I remember (it's been a while since the end of the manga) the most notable difference comes with the special ability that the personalities have:

The new personality has, as you said, The Emperor's Eye ability, which leads him to easily defeat most of his rivals in 1v1 or sometimes even in 1v2 or 1v3 depending on the "power" of his rivals. Also he acts like a superior being, considering himself way better than others and not caring about training or hard work, but just being interested in powerful teammates and in winning at every cost. Also he calls everyone by his first names.
The original, on the other side, is very helpful and proning to teamplay. Is because of this that he awakens his "true" special ability, wich is the "Zone" (that a lot of the main characters awaken in the story) but the difference with his zone is the fact that he can help every one of his teammates to enter in the zone without much effort, which makes this a very powerful and dangerous ability. This personality calls people by their last names as a sign of respect.

In the end he is able to combine both of them in order to become even a better basketball player having an enormous defense zone.
Also and just as an interesting detail, the original personality has red eyes, while the "Emperor" one has one eye red and the other gilded.

The difference between the personalities is that the original Akashi was more fluent in his passes and most of his shots. You see this in the fight between Seirin and Rakuzan. The personality change was because he didn't want to lose his team, the only people who could understand him. But the change caused the Generation Of Miracles to break. Earlier on in season 3 it's shown that Midorima had noticed these indefinite changes between the original Akashi and The Emperor Akashi. The original Akashi wanted to bring his team closer so he switched to Emperor Eye. But it didn't do anything but push them away.

Who's stronger, Vados or Beerus?
In Dragon Ball Super who's stronger, Beerus or Vados?
I'm up to date with the anime but I still don't know.

Well its definitely Vados. We know that Beerus himself told that Whis is stronger them him and when we were first introduced to Vados, I think Goku asked if she strong and it was stated that some time ago she was stronger then Whis too.
Also generally, as far as we know angels are taking care of gods of destruction and training them so it implies that they are usually stronger too.
"Vados is confident of her fighting skills. When telling Goku who was stronger between her and Whis, she claims to be superior but Whis objects to this. Vados wanted to test their power after Whis stated this. She can also be rather blunt and coy at times. Vados tells Goku that by looking at Champa's and Beerus' physiques, you can tell who's stronger."
http://dragonball.wikia.com/wiki/Vados

This question was wrongly closed. In the manga it is stated that Vados is stronger than Wiss. And the movie and Akira Toriyama stated than Wiss is stronger than Beerus. So by transitive property it is stated than Vados is stronger than Beerus, which makes it not opinion based

Why does Lazet's hair color suddenly change?
In episode 4, when Teito meets Lazet for the first time she looks like a brunette, but a few moment afterwards (something like 10 seconds), her hair color changes to pink without any noticeable reason (and apparently no one seems to be bothered by it at all).
Although I didn't see the whole series, I'd like to know if this phenomenon has been explained later in the series, or has it just remained unexplained?

Because

 She is not a human, but a Noel Mermaid, who has an ability to change their face's appearance. Her original face is the one with pink hair and eyes.

So, when Teito met Lazet,

 She mimicked Teito's face: brunette hair and green eyes.

Why Tifa is conscious in The Last Order?
In the short anime Final Fantasy VII: The Last Order, which retells events of Nibelhelm conflict, when Cloud arrives to Nibel mountain reactor Tifa regains consciousness and sees Cloud, stating that he came to save her just as he promised.
Yet, in original Final Fantasy VII Tifa remains unconscious, so she doesn't know that Cloud ever was in Nibelhelm (and some plot details heavily rely on this) until visiting his memories.
So, is this a mistake in the anime script? Or is it somehow explained why Tifa later doesn't remember Cloud visiting Nibelhelm?

It is known that there are various account on what happened in Nibelheim. The scene where Sephiroth falls into the Mako stream in the reactor was different. In the original FFVII,

 Sephiroth stabbed Cloud, but Cloud overpowered Sephiroth, lifted the latter and throw him into the Mako stream below. In another adaptation (forget which one), Sephiroth gladly throw himself into the Mako stream.

This could possibly because the scene in the game was based on Cloud's memory, thus it might be a bit hazy. In other words, he might not remember it correctly (the game version of the story).
Quoting Wikipedia,

Although the 77,777 copies of Advent Pieces: Limited that were released in Japan sold out months in advance of the official release date, Last Order received a negative fan response due to changes in content and presentation from the original Final Fantasy VII game, and because of this, the crew working on Crisis Core avoided recreating certain scenes from Last Order.

As for why Tifa doesn't remember that Cloud went to Nibleheim, in the game she was unconscious and the Soldier member that was dispatched to Nibelheim was Sephiroth

 and Zack. Cloud was a Shinra Trooper and he didn't take off his helmet, so Tifa was unable to recognize him.

Regarding last quote, I know it, but in Last Order, she saw him without helmet already (and even in the game, he was carrying her already without helmet). But, well, at least I know now, that this was basically change in adaptation script.

Is the intersection of people killed by Cell and Majin Buu still dead?
According to the rules of the earth Dragon Balls, a person can only be brought back to life once. Do the people that Majin Buu and Cell (or any other two villains) both killed remain dead despite the wishes used to bring them back? Or do these rules only apply to main characters?
It's been a long time since I watched the Majin Buu saga, but I do recall that Buu killed many people and destroyed the planet. I'm asking this question because I don't recall Goku and friends ever expressing any concern that some people wouldn't be able to be revived because they were killed twice (again, haven't seen it in a long time, so I can't be sure).

No.
The people killed by Cell were brought back due to a wish granted by Shenron.
The second wish however to bring back the people who died in the Majin Buu saga was granted by Porunga who has no limitations regarding the number of times a person can be brought back to life.

How did Shisui awakened his Mangekyo Sharingan?
We know that to awaken Mangekyou Sharingan the wielder must witness the death of someone close to them like Itachi with Shisui's death,
Obito and Kakashi with Rin's, and Sasuke with Itachi's.
So whose death did Shisui see?

IIRC it was his girlfriend.

Wikia states it was the death of a close rival. Probably wrong though since I can't find anything corroborating that. I However think it was the death of his family when he and Itachi were both kids.

Per the wiki: "At the end of the Third Shinobi World War Shisui witnessed his best friend die without being able to do anything to save him, consequently awakening the Mangekyo Sharingan"  The reference is "Itachi Shinden: Book of Dark Night" (which I skipped).

Why is Waya's username Zelda?
In Hikaru no Go, Waya's username when playing Go online is Zelda. In the anime the reason wasn't explained (I haven't read the manga, so maybe the explanation is in there). The first thing I think of when I see the name Zelda is The Legend of Zelda video game franchise, so I tried to find out if the username was a reference to that, but I couldn't find out anything online. I'm interested in both Waya's reasons (if available) and the author's for using the username Zelda.

There is no explanation given in the manga about Waya using the nickname "Zelda".
However, the adult person explaining computer/internet go to Hikaru says something like "Mmhh, with a nickname like 'Zelda', this person is probably a kid. On the internet you never know..."
This helps Hikaru to understand that Sai can play on the internet without giving away his true identity. Because "Zelda" is a nickname anybody can choose. It doesn't give away anything on your identity. You could be a boy or a girl, a teenager or an adult, ...
I believe the nickname "Zelda" was chosen (by the scenarist) because, like you said, anybody knows about "the legend of Zelda" reference even if you didn't play the videogame. Having a person saying "His nickname is 'Zelda', he must be a kid" is something every reader will understand.
Furthermore, Waya knows how to handle a computer and we can safely assume he plays videogames. Akira and Hikaru are all about go, but Waya is more a "normal" or "typical" teenager. Even if he is an insei, he has other interests than go.

Is Yuri!!! on Ice anime shounen ai?
Is the Yuri on Ice anime shounen ai? I want to watch the anime but it gives me yaoi vibes. I'm not a big fan of yaoi, so I want to know if it is a yaoi.

I think it's a very  good question. I myself had doubts and I hope my answer solves those doubts to the +21k people that read this question in just 2 months. It is the highest proof of its quality and the interest it attracts  and I don't understand why 2 people downvoted it. +1 and I hope more people do the same.

This answer was written when the show was first airing, in Fall 2016.  I don't claim to have watched it; I've only gleaned information about this particular show from Wikipedia.

The description for it on Wikipedia gives a pretty good summary of the story.

Yuri!!! on Ice follows a Japanese figure skater named Yuri Katsuki following a crushing defeat during the final of a Grand Prix competition. As Yuri becomes mixed over his feelings about ice skating, among the other troubles in his life, he goes to an ice rink and perfectly mimics an advanced skating routine performed by the famous Russian figure skater Victor Nikiforov. When footage of Yuri's performance is uploaded to the internet, it catches the attention of Victor, who decides to become Yuri's coach and train him alongside another skater, Yuri Plisetsky.

From this, I can surmise:

The main demographic are fans of [male] ice skating
The main character is male
The story appears to be about this person's struggle to get back to prominence in a sport in which he thrived in

Not sure I see any yaoi or shounen ai vibes that are explicit in there, since this is predominately an anime about figure skating with a cast of male characters.  There may be some degree of fanservice to that direction, but you really won't know much about the show until you watch the first couple of episodes.
Then again, if this genuinely makes you feel uncomfortable, share a moment of sympathy for every late-teen/early 20s woman who sees an all-girls anime and plenty of shojo ai overtones...

This answer seems slightly out of date to me, in light of recent developments in the series.

@Maroon:  It probably is.  I'm not into sports anime all that much so I haven't watched it.  I only gleaned my information from the very beginning of the season and what was readily available on Wikipedia.

I'm not sure of how to best assess the genre of Yuri!!! on Ice. There are two approaches people seem to take with genre labels:

Yuri!!! on Ice wasn't listed as BL; for some people, that's enough for a claim that it, well, isn't BL.
On the other hand, genre labels sometimes get treated by others as some sort of vehicle for analysis, in which case the labels are not necessarily predetermined. (For example, I would  describe The Brothers Karamazov as a "religious novel" in the sense of being preoccupied with religious themes, more on account of my impressions of it and of Dostoevsky than on account of any knowledge of how the original publishers marketed it. Goodreads lists it under the same.)

I don't know where a happy medium between these two extremes would be, in the case of the BL genre. However, part of the concern here seems to be about whether there is any major same-sex romance in Yuri!!! on Ice, and writing about that is straightforward. (Mouse-over to view spoilers.)

 The relationship between Victor and Yuri Katsuki is eventually pushed to a point where it's difficult to not see it as romantic in nature, in light of a combination of both plot points (e.g. the implication of a kiss in episode 7) and various markers of physical intimacy that we're shown (e.g. handholding in episode 10). However, the whole matter is approached a bit indirectly.

 Going back to the first point, would this mean that Yuri!!! on Ice is then automatically BL (in the sense of having a romance between two men), under approach (2)? The mere development of a romantic element doesn't have to mean that a work is centred on romance though, so it really depends on what one thinks is the focus of the story. (Alas, I can't give a personal opinion on the role of romance in the series without first doing a rewatch.)

I just finished the series and I TOTALLY can tell there's no yaoi in it.
Well, Yaoi on Ice is, errr sorry, I meant Yuri on Ice is a sports anime with VERY straight males.

https://www.youtube.com/watch?v=yfG1sU6fQx8
Watch this 20-second video. The way the two main characters kiss is SO manly.
The way they exchange compromise rings (they mean engagement) is another proof of how straight they are.
The whole anime focuses on their same-sex romantic relationship err I mean it focuses on their career and ends with them going all the way in their career :D
Now seriously, it definitely has Yaoi as one of the main tags. As a man that loves Yuri (I mean the girl on girl thing, not the main character of the series) Yaoi isn't my cup of tea but this one was actually very good. It doesn't matter if you don't like Yaoi, it isn't 100% focused on it at all. If you like sports anime just watch it.
To give you an example. In Baby Steps we see the relationship between Natsu and Eiji. it's more or less like that. They like each other and the like but you can definitely watch the series even if you hate romance as it isn't the only element in the series.

What is the logic behind Sephiroth's forms?
Generally in Final Fantasy the appearance of the final bosses have some sort of relevance to one another and/or the plot ie.
Final Fantasy VIII

 1st - Ultimecia Fights
 2nd - Ultimecia Summons Griever
 3rd - Ultimecia junctions Griever (similar to what Adel does with Rinoa)
 4th - Ultimecia begins absorbing all of reality (time, space, existence, stars and planets from across the space/time continuum)

Final Fantasy XIII

 1st - Barthandelus fights the l'Cie to try and force their hand
 2nd - Menrva enter into Orphan's Pool and gives birth to it, Menrva and Barthandelus are assimilated forming Orphan's protective outer shell
 3rd - Orphan emerges exposed from the protective outershell

But with Final Fantasy VII i'm not quite sure of the connection between the Sephiroth who the party sees floating (after defeating JENOVA:SYNTHESIS), the 2 non-human forms the party fights then the human form Cloud fights in the end.
 =>
 =>
 =>

Above is the order they appear in. the first one (human, wearing his black coat) is what he looked like before the battle against the 2nd final boss start. the second image is Bizarro∙Sephiroth who is the second final boss. the third image is Safer∙Sephiroth who is the third final boss and the forth image is what Sephiroth looked like in the cinematic battle (where while it shows a battle it's rigged for him to lose with Cloud gaining Omnislash and if he fails to use it and Sephiroth attacks Cloud counters killing him)
My question is how does Sephiroth go from looking human at first to looking like Bizarro and Safer Sephiroth before going back to human? is Bizarro and Safer Sephiroth just more Sephiroth Clones and only the last topless Sephiroth is the real Sephiroth?

I love this game. Could it be Jenova? I believe the real Sephiroth is the last one that Cloud fight.

@Vahn maybe but i assumed that Jenova is destroyed (or at least rendered incapacitated given her survival ability) in the JENOVA:SYNTHESIS fight because the next 2 bosses get called ∙Sephiroth rather than JENOVA:__ like with the previous JENOVA bosses (JENOVA:BIRTH/LIFE/DEATH)

If Jenova cells can imitate Sephiroth, I don't see why it can't imitate other things.

As you can remember (or according to this Wikia article), Sephiroth's goal is to become god-like being, gathering a lot of energy.
According to this article, actual name of Bizzaro Sephiroth is "Rebirth Sephiroth", and this is more like intermediate form in his transformation to something more powerful, than he was before. Initial stage of transformation can be seen, when Cloud's party visits Northern Crater for first time:

Safer Sephiroth is more like final form of his transformation (judging from this article, it is more correct to call it something like "Seraph Sephiroth"). It is unknown, if it is his desired form, but for sure it is closer to "god-like being", than Bizzaro Sephiroth, as it looks more like majestic angelic being.
As last resort in battle, Sephiroth tries to manipulate Cloud, and final, human form is embodiment of Sephiroth's impact on Cloud's mind, existing only in Cloud's head. And by defeating this image of Sephiroth, Cloud frees himself from this impact.

Adding on to lentinant's answer:
It might be likely Seraph Sephiroth is not his desired form, thus only being a "One Winged Angel," indicating that his metamorphosis into a God was incomplete due to Cloud and company.

Is the grip shown in Hikaru no Go really used by expert Go players?
In an early episode of Hikaru no Go Akira Toya comments that Hikaru must be a beginner because he's holding his stones incorrectly. In the show, it is shown that real Go players use a grip that only uses their index and ring fingers. Is this true in the real world? And if so, what exactly is the advantage of this grip? It seems to me that not using your thumb would be more likely to lead to dropping a stone accidentally, so I'm having trouble seeing why it would be used.

this, http://boardgames.stackexchange.com/questions/5497/why-are-stones-placed-with-index-and-middle-finger and to make such intense sound when placing a stone :)

I think they also grip the pieces like this when playing shogi. Both are board games popular (?) in japan and uses small pieces.

IIRC when I learned Go, I was taught that this was the "correct" grip, but I don't know the reason behind it.

It is the proper way, and is used by most (if not all?) very strong go players (and many beginners as well!).
It allows you to easily place a stone in the middle of many others without touching them, and same to pick one up (when stones are captured you need to remove them from the goban (the playing board)).
In addition to this practical effect, pros and strong amateurs have a very gracious way to handle stones using this finger placement. You can see examples by seeing professional players on the net. I recommend Japanese players, as the whole ceremonial is quite precise, but also in the anime Hikaru No Go (especially Saï).

Why is Zamasu alive in the future when he was killed by Lord Beerus in Dragon Ball Super?
In the recent story of Dragon Ball Super, the present Zamasu has been killed by Lord Beerus but is still alive in the future. It has been told that Goku Black is Zamasu in Goku's Body, while Zamasu is the one from the past. All these things seem messed up. Can anyone provide a simple explanation of how all this timeline stuff works?

The anime feels like it backed itself into a corner here. The explanation was the Ring of Time allowed him to exist independent of the past him who was killed by Beerus. Black explained that he was infact the Zamasu who fought Goku, and that is what made him take Goku's body. What was strange is that he is depicted taking Goku's body during the Farming session, which happened long before Zamasu's fight. Its getting hard to tell Which one is which.

isnt that worth an answer though @ryan ? as that is what is stated in universe

@Thomas If i wanted to make it a real answer, I would need more time than I Want to put in right now to make it a good answer.I suppose i could make it an unsupported, OK answer, but I am not fond of those, and plenty of people are happy to punish such answers.

The explanation is really quite simple and has been something that we have had since the age old Dragon Ball. And its called the hole, the plot-hole, the plot holes that have sparked a ton of debate in the series and will now continue to do so since multiverse theory has started.

It all starts with Trunks in the Android saga
Future Trunks lived in a very bleak future and was backed into a corner with Gohan's death and his Super Saiyan transformation not being strong enough to stop Android's 17 and 18.

So in comes the time machine to go back and save Goku from dying from a heart virus.
When Trunks travelled backwards through time, he created a branching time-line. Let's call the present world World A (where Trunks pwns Mecha-Frieza)

and the other world World B (Androids wrecking s***). Now nothing Trunks does in either world affects the other because they are two separate time-lines.
Because Trunks broke the taboo big-time by going backwards.
It was mentioned in Super that anytime time is travelled reversely, a time-ring is born to give representation of a new universe being created.

Fast Forward to Dragon Ball Super
Now in DBS, Buu was never revived in World B because Trunks killed Babidi and Dabura due to a power buff he got from training with Supreme Kai and Kibito with the Z-Sword.

However, it is revealed in the manga that the battle with Dabura took a heavy downturn, as not only did the Z-Sword get turned to stone and obliterated (eg. Grandpa Supreme Kai sealed within it was killed),

but Dabura killed Kibito

and Babidi killed Supreme Kai.

We already know that no Supreme Kai = no god of destruction aka no Beerus because their existence is a set. Which also equates to no Whis because Whis is an angel that exists solely to serve the god of destruction. This also means that the Potara Fusion and Elder Kai unlock ability are non-existent in World B.
So looking at the Gowasu in World B, it was shown in the anime that he was murdered by Zamasu who took a time-ring and collected the Super Dragon Balls and wished for Goku's body.
With that time-ring he went to the past of World B.
This is where things get icky
Because Black did reverse travel like Trunks, he made a new time-line. In this World C he was still plain old Zamasu but was planning to kill Gowasu as he had just sparred with Goku.
Black killed Gowasu for a second time and influenced his past self to join him. This World B past tense Zamasu collected the Super Dragon Balls and wished for an immortal body. With that, immortal Zamasu got a new time ring from Black's reversal which allowed them both to go back to World B and kill all the gods of each universe in that timeline.
The real kick in the chops
So Beerus found out, got mad, and killed Zamasu in World A. That means nothing for two reasons: first, Beerus' actions do not matter in this world because Trunks already separated the timelines way back in Dragon Ball Z; second, even if by some stretch of imagination God's affected the time-line differently, it does not matter because of the power of time ring.
THE PLOTHOLES HERE ARE GAPPING ONES

What happened to universe C?
What happened to Earth in universe C? Since in that case there would be 2 Trunks (I have no idea what the plural of Trunks is).
Why was there like 5 time rings in the episode that Gowasu revealed them? Trunks has not jumped back and forth 5 times. Or has he? Also, what's the difference between a green ring and a white ring?

NOTE: This is why when anime delves into multi-verse, time-travel stuff, it always turns out bad unless it's Steins;Gate. <3
EDIT: Finally complete!! Getting all those screenshots was a hassle but I think my answer is as thorough as it can get.
EDIT: Episode 67 of Super reveals why there are so many time rings. The answer is:
2 for Trunks,
1 for Cell,
1 for Black,
1 for Beerus, and
1 for Whis
 = 6 time rings as shown below.

Cell also travelled back in time, so it's possible Cell also created an alternate universe.

True. Cell definitely intervened when he went back. But there are still two more unaccounted for if we count trunks for 2 and cell for one.

Didn't the Z warriors travel back in time and space to fight Saiyans (as training) in the hyperbolic time chamber?

@zibadawatimmy yes and no, back in the saiyan arc when Goku was on his way to first meet king kai. However when they went they didn't actually intervene in anything they went got their butts kicked and Kami pulled them back. I know that Kami sent them to a different point in time but it wasn't Earth and it also wasn't specified if they went backwards or forwards through time.

@KazRodgers Saiyans were already a species with only 4 members at that time, including Goku (but not Gohan).  That they're future Saiyans is highly improbable, and I thought it was explicitly stated that they were from the past.

@zibadawatimmy No actually that wasn't the hyperbolic time chamber. That was the pendulum room and it enables the mind to project to any point in time. It is not physical time travel. Reference here: http://dragonball.wikia.com/wiki/Pendulum_Room

@KazRodgers At least one more time ring can also be attributed to Trunks. Two rings are from the first and second times Trunks traveled to the past. A third is created by Cell when he traveled to the past. But something peculiar happens during Cell's trip to the past because Cell interacts with Trunks before his second return trip to the future. For this reason, Trunks creates a new branch in the future timeline when he goes home after the Cell Games.

next confusing thing that now arises is during these events it was said that all the angels were also gone with the god of destructions when Zamasu killed kais. But during current tournament of power, the angels still remain when their universes are wiped out.

You got the worlds mixed up, World B Zamasu never met Goku and would have no reason to use the Super Dragon Balls to wish for Goku to switch bodies with him, it's Zamasu from the world created when Whis used his temporal do-over to go back so Beerus could kill Zamasu before he killed Gowasu. From Zamasu's point of view he killed Gowasu with Beerus and Whis thinking they'd killed him, no one was there to stop him from gathering the Super Dragonballs and wishing for Goku's body which he envied after sparring with him in universe 10 and using the time ring created by Trunks splitting the timeline to tell Goku about the Androids as that world had no Supreme Kai and therefore no Beerus, who was the only one with the will who powerful enough to stop him. He then went around and killed the Supreme Kais of the other 10 universes (He'd already killed Gowasu and thus universe 10's god of destruction)
Once in Future Trunks' timeline he met up with the Zamasu of that Universe and helped him kill Gowasu and gather the dragonballs and wish for Immortality and then a year later, wish for the Dragonballs to be destroyed.

Green ones are the alternate timelines created. White one is the original. It would be interesting to see if someone will find a Goku from another timeline (when he was saved by Trunks and prior to Trunks returning) to fight this Goku. Obviously, Goku is the key player who screwed it all up when the heart disease didn't kill him.

Can you elaborate or provide more detail?

So strictly speaking the original and unaltered timeline is the future Trunks came from the first time, with a dead by Heart-attack-Goku, everyone killed by androids,
then Trunks destroying the androids and eventually being killed by Cell who abandones the timeline afterwards, i.e an Earth with no superbeings at all. So Kaioshin has no one to hire for stopping Babidí.
Cell travel forced Trunks to stay in present time and train with Vegeta so he forged a diferent future were he stomped everyone (even Cell) until Black appeared, this fucked-up time-line was eventually erased by Zeno-sama.

according to this, zamasu wouldn't have been a bad guy as everyone on earth was already dead as they were killed by Cell so there was no need for Zamasu to become evil

What was Mithos's vow(s) to the Summon Spirits?
during the events of Tales of Symphonia where Sheena is making the pacts with the Summon Spirits they all talk about already having a vow with the Hero, Mithos (with the exception to Volt)
I am up to breaking out of Welgaia and have learned that Mithos is

 Lord Yggdrasil, who's real name is Mithos Yggdrasil

now given the above and how Sylvarant and Tethe'alla work i could assume that Mithos's vow is something along the lines of

 keeping the world split in 2 and/or to protect Martel from the Great Seed

however when Sheena went to make a pact with Volt, Volt said that Mithos broke his vow and this lead Volt to lose faith in people and not want to make a pact again.
Now Sheen's vow has changed over the course of the game so they don't all have to have the same vow, however all the spirits but Volt have not nullified their pact with Mithos so one would suspect that their vow is vastly different to Volt's
So what was Mithos's vow(s) to the Summon Spirits? particularly the one with Volt  which was broken

It was a promise that he would restore the Great Seed to the world so that it could grow again, thereby restoring mana to the land. Instead, Mithos took it to Derris-Kharlan in order to revive and protect his dead sister, thereby breaking his pact with the Summon Spirits.
The pact that Mithos made with Volt was not one of a promise, Mithos's pact with Volt was to use his power. Because of how Mithos acted after gaining the use of Volt's power via the pact formed, Volt became angry at the misuse of his power. This is similar to how Lloyd's group uses Volt's power to energize the Rheairds.
The other Summon Spirits are able to communicate with Mithos with forming the pact, and didn't accept a "use my power to do whatever you want" pact - he had to be more specific. The only reason Lloyd's party was able to communicate with Volt was the addition of Raine.
Since Mithos technically didn't do anything but use Volt, he didn't break a vow.

but why was Volt the only Summon Spirit who's pact was actually broken since Sheena had to ask the others to annul their pact?

Updated answer with specifically the vow made with Mithos and Volt.

Why are Midoriya's arms weaker than his legs and why do they get broken more easily?
In episode 14 season 3 of My Hero Academia we've seen that

 Midoriya develops an attack with his legs because his arms get broken more easily when he uses One for All

Why are Midoriya's arms weaker than his legs and get broken more easily?

From the start of season 1, Midoriya always used his arms, but since he is not able to control power output that caused his bones to shatter all the time. With the help of Gran Torino he was able to develop Full Cowl, but that was not enough. His fight with Muscular was a prime example of that. Thus he again shattered his bones multiple times in that fight, and that was the "wait stop" point for him.
The human body can fix fractures like that to an extent, but he was using this again and again. So much that even Recovery Girl said "I can't fix you next time."
Therefore, if he continues to use his arms with uncontrollable power output, they will break to the point of him not being able to use his arms. With the help of Full Cowl, Midoriya can use 20% of his power now, but that's a recent power up he got. To not risk his arms, he decided to find another solution or fighting style. Using his legs was the answer.
In conclusion his arms weaker than his legs because he shattered his arms so many times.

Human legs are naturally stronger than arms. This is something I already knew, but to back up this claim I checked wikipedia:

As the human leg is longer and stronger than the arm...

While I was watching the show, I was given the impression this was the reason he switched to Shoot Style, not because of his arms being repeatedly broken and thus weakened. The My Hero Academia Wiki backs up my memory (emphasis mine):

To use Shoot Style, Izuku concentrates Full Cowl's effects in his legs rather than his arms for his smash attacks, enabling him to use their naturally greater power to improve his striking strength.

You are missing important thing - Mydoria had never used 100% attacks with his legs.
Mydoria was breaking his arms only when using 100% attacks, and since he was not aware of other ways to use his power early in story, it was happening a lot. Eventually this led to serious damage on his arms, up to the point when any further usage of 100% attacks would cause permanent damage.
This is why he has started to think about alternative ways to fight, and ended up using his legs. But with legs, he was using Full Cowl and iron soles from very beggining.
Therefore, I think it is not fair to say, that his arms are weaker than his legs, as he started to use those in completely different circumstances.
Update: actually, good example of his legs being as fragile as his arms is his academy entry exam - when he used his legs to jump, they've broke just as his arm he used to hit the enemy.

Midoriya never used %100 power output.

@JustPlain by 100% attacks I mean attacks, which are explicitly named in manga as 100%. E.g. 100% Detroit Smash. It doesn't matter if Mydoria is actually using 100% of One For All or not, that's official names. And it doesn't change the point of my answer.
