Straw Hat Luffy gonna destroy the Fishman Island?
During the Fishman Island Arc, Madam Shyarly's in Coral hill predicted that a man with a straw hat is destined to destroy the Fishman Island.
They say Madam Shyarly's prediction never failed. I can't  think of any other besides Luffy that is wearing that hat.
How can Luffy possibly do it? Because in the first place, he saved that island and he's not that kind of guy who will do such a thing. Also, Fishman island lies right underneath the Red Line and Mariejois. So destroying Fishman island means destroying the capital of World Government, Mariejois.
Questions:

How can Luffy possibly do it? (if he is the destined one because it lies beneath Mariejois and Red Line)
Could this be another straw hat guy? or her prediction is just wrong?

it don't have to be luffy. Someone with a strawhat or even someone could take Luffys strawhat and destroy the island. So i don't think this person will be luffy at all.

I think she saw destruction in the fishman Island and she saw luffy at the center of it so she assumed it was him or rather there was no indication that proves luffy was not at fault. the turn of event could put luffy in the center of a destroyed fishman island but it could be for number of reasons. maybe she just interpreted the vision wrong!!!

Strictly speaking there are at least 4 possibilities which are all possible:

Luffy's actions could bring about the destruction of Fishman Island due to his risky behavior.  For instance: he claimed it as his own and challenged Big Mom for it so she could destroy it and it would be Luffy's fault.
Someone could destroy it impersonating Luffy in order to turn his rapidly growing group of allies against him.
Luffy could change the island so much that it could seem like destruction. He could, for instance, bring it to the surface or promote desegragation of the world so an island inhabited by just Fishmen/Merfolk is no longer a thing.
Finally, Luffy could be forced to destroy it for strategic reasons such as might be required in the "alter the Red Line so there is just one Giant Ocean and the world can be easily transversed" fan theories.

Ulitmately though, we don't know what will happened and any theories are speculation.  The residents of Fishman Island have been convinced that Luffy will do them no harm, even though that is foolish, as Shyarly's prediction are reportedly never wrong.  We can assume from his character, however, that he will not intentionally do anything to harm Fishman Island without suitable recompense. We can also assume, however, that this important plot point will not be forgotten and Oda will provide an explanation in the plot at a later date.

There are many things needed to be considered to answer this.

First is the unfulfilled promise of Joy Boy to Poseidon, this promise includes transportation thus they created the Ark Noah. Ark big enough to carry all Fishmen. The Fishmen kept on protecting the Noah believing that one day Joy Boy would fulfill this. In my speculation this Joy Boy is actually one of "D." Luffy's ancestor, this would make sense why Roger and Luffy was able somehow to hear Sea Kings. Leaving Luffy to fulfill this.
Second is the fact that Luffy accepted Fukaboshi's wish to "bring them to Zero" or surface of the sea because they're friends, as how Luffy said.
Third is the fact that the Straw Hats made a pinky promise to show Shirahoshi around the surface to see the real forest, racoons, etc.

All these facts "may" lead Luffy and his crew to bring the Fishmen to the surface and this could be the very reason for Luffy to destroy the Fishmen Island for some reason like the fishmen might refuse to leave their island leaving Luffy no choice but destroy it would be a possibility. Because no matter how I look at it an island kept at the dark bottom of the sea isn't something nice, something Luffy might think himself. But since the species of Fishmen are discriminated by the world, Luffy requires power before doing this to carry and protect the species under his name like how Whitebeard protected the island as a Yonko.
As for how to destroy the island. You could come up with many possibilies like maybe popping the bubble that is keeping it afloat, or use force to the center of the island enough to destroy it, or somehow talk to the Sea Kings, or a fierce battle, etc...

Luffy does not destroy Fishman Island. However, it is a possibility that it could happen considering that the islands of Raftel (where One Piece is located supposedly) and Mariejois (the tenryubito homeland) are possible arcs that could bring about a calamity strong enough to make that happen.
Right now it's simply too soon to say.

Since Madam Shyarly predicted that a man with a straw hat would destroy fishman island in the future, it cannot be ascertained from this statement only what would be the state of fishman island or the world when this would happen. Assuming the man was straw hat Luffy, it still opens up endless possibilities. One of them could be and I personally prefer this one, the fishman island is taken over by an enemy, either the world government or a yonko and killed all the fishermen who were there and weren't able to escape. Doing so has shifted the balance in power and if something isn't done immediately, the world would come to ruin. This could be during the great war which might happen at the end or before that.
These all are just theories and it all finally depends on Oda and well Oda never takes the obvious way out.

 I don't think with the introduction of DF awakening and seeing how strong Pica, or whitebeard were, it's farfetched to say that a single individual can destroy an island.

According to this wiki:

 She (Madam Shyarly) is also very accurate in her predictions as she predicted the Great Age of Pirates as well as Whitebeard's death. She recently made a prediction that a man in a straw hat, who she presumes to be Luffy, will destroy Fishman Island. However, Luffy left Fishman Island without destroying it so that prediction has not come to pass. But since events that Shyarly foresaw can happen anytime from a day to a year later, there is still a possibility that Shyarly's prediction is not wrong yet. By breaking her own crystal ball, Shyarly has given up on her scrying abilities.

I used spoiler tag because I think you are not finished to watch or read until the end of Fishman Island Arc.

Actually I'm done with the series and I'm updated to the present. I like reading Wiki's but I disregard it now as reference as its an editable source. I'm thinking if how Luffy could possibly do it(if he is the predicted one)? because fishman lies below mariejoris, the capital of WG.

well then, if Straw Hat that Madam Shyarly said is Luffy, I think it's related about the equality between human and fishman in the future.

Here's my speculation on why Luffy will destroy fish men island.
It could be because that fish men no longer has the need to live under water and they can live amongst humans so luffy simply destroyed fish men island as it is not needed.

What did Yuji do to his sister Kazuki?
In Grisaia no Rakuen (Paradise), after saving Yuji and retrieving the real body of Thanatos (Kazuki actually), there was a scene (aboard the ship Mihama Academy) when Yuji got pissed or irritated due to Kazuki's "bossy" attitude. Yuji yelled "Kazuki!" and then he dragged her to some place on the deck. Afterwards, when they were "finished" Kazuki said: "Dont ever do that to other girls anymore..."
My question is: What did Yuuji do to Kazuki? Is there a manga that explains this?

The show was based on an eroge, so it would be very obvious what he did to Kazuki. Plus, she said "You must not do 'those thing' to any girls other than your sister.", emphasis on the word OTHER. So, you should have been able to infer that they had sex.

@MikeAgustin not all that strange. public sex can be a turn on for people

@Memor-X im just kinda puzzled, why didnt they show the clip? they are other anime that shows intimate scenes like "futari ecchi"..

@MikeAgustin to my understanding it's a choice on who the targeted demographic is and what the studio wants to be the classification rating. showing sex scenes will get the series restricted to certain timeslots on TV (such as being late late night) and ratings for home release like with Speed Grapher which in Australia is MA 15+ which is the level bellow from R18+ Restricted (which i think is the level bellow X). i'm not sure about Japanese classifications or what it was for Grisaia no Rakuen but i assume not showing it at all allowed them to air the show at their targetted audiance

@Memor-X I kind'a rewatched the anime, and there I remembered there was a scene about yuuji doing Julia's "first time". I wonder why they didn't show deck scene.

@MikeAgustin i dare say the incest would play a factor in that. i havn't seen the series or played the game so i've no idea

@ Mike Agustin That scene with JB was also not directly shown, similar to how it is here, just implied by showing them lying on the bed together, thereby making it more obvious than this scene with Kazuki here. Plus, there was also Yuji's scenes with Asako, which were also not shown but directly said in JB's conversation with Asako.

Really got not much reference here but there are two versions to this story in the game, the safe mode where it was Yuji giving Kazuki a shoulder massage and the 18+ mode where they had sex, not sure which side the anime adapted but I think it is the 18+ side with that ambiguous scene but it is totally up to the watcher's imagination here. In that link, the commenters mentioned what they thought of the episode compared to the game so just go ahead and read those, if that is insufficient as evidence then I will leave the proper answering to someone else. But yes, they totally did say that they had sex in the game.

Generally the trend i find is that if there is an all ages version of a 18+ Visual Novel and the anime isn't hentai it'll will adapt the all ages version, example are Fate/Stay Night (where Realta Nua was used) and Tears to Tiara (where the PS3 Remake was used) and i would suspect Utawarerumono as well (where the PS2 version was used). though thinking of a sister saying that her brother can't do massages for other girls is kinda strange but i've neither played the visual novel or seen the anime so i don't know if the scene is from an incest route

Yes, it is most likely they adapted the safe version since the sex scenes were missing from both the Kajitsu and Eden animes and the commenters said how that scene was missing from here as well, and it is just what she said here that makes me think it is from the 18+ side. So, yes, I cannot prove whether it is the 18+ storyline or just a shoulder massage.

They totally have sex. In the Labyrinth episode, where Yuuji was young, Kazuki takes him in the bath and explains what incest is. When they get in the bath and it fades out, Yuuji says that he, "learned a lot from his sister." The fact that Asako thought she took his first time was a misunderstanding from Yuuji's lack of communication. He'd obviously been molested while under the "care" of Heath Oslo, so even though Asako sad she took his first time, she was... well.. a little further down the line. Even if this hadn't been based on an eroge, which I didn't realize it was, that scene when the siblings were young, mixed with the fact she said he mustn't do that with any other girl than her, they had sex. And that Kazuki isn't as knowledgeable as she thinks.
Also, as a side note, I think the fact that Yuuji then thought to himself, "What does she mean by 'those things'," means that he obviously doesn't see what's wrong with it, which makes sense, since he's been having a lot of sex, willing or not, since he was young. Kazuki playing the pronoun game probably just confused him.

I'm pretty sure he had sex with her now that I've think about it. This is by no means canon but from what I can tell, is that he has been raised having sex almost constantly with Asako. So it would not be a stretch to say he took having sex as a way to express his love. He did specifically say Asako is the most important woman to him.

Considering the eroge it's based on, it is very likely that they had sex. Considering the complete and total loss of his family before either him or Kazuki were at an age where someone had explained the nuances of sex, it is entirely likely neither of them realize that them having intercourse is actually wrong. They have both been detatched from mainstream society for some time with the exception of Kazuki who lived on the internet, and if you can find a place where someone can justify incest and almost make it sound legit, it's definitely the internet.
Regardless, I choose to pretend that he just gave her a shoulder rub for obvious reasons. "You mustn't do those things with girls other than your sister" obviously does not make ANY sense at all in a sexual context, I mean really.

How did the Straw Hat crew become stronger in Enies Lobby?
In Enies Lobby, everyone looks like they've suddenly become stronger (and have
new techniques). Luffy, learned how to pump his blood and his bone. Sanji, learned how to burn his foot. Nami, learned to do Fatamorgana. Zoro with his Asura?
Which part in the story that tells how they got such power?

I found an interesting answer to a similar question on Reddit:

The main idea behind their power jump is that when the Strawhats first fought CP9, they were largely confused and unsure. All they wanted to do was get Robin back, and only attacked CP9 after they got in their way. Note that in the Galley-La mansion, Luffy tried to reason with Robin first, and only attacked Lucci twice: once to defend Paulie and afterwards while Robin was exiting the room. Zoro attacked Kaku only after Robin was leaving as well. It's the same with Sanji on the sea train; when he kicked Blueno, Sogeking was holding Robin. Sanji wasn't trying to beat Blueno, only make him let go of the kart.
  Does that mean the three of them weren't going all out? In a sense, you could argue that: Why go all out on an opponent you don't even need to defeat? Would defeating them have gotten Robin back? Absolutely. But the Strawhats typically avoid conflict unless necessary; as evident by the fact that Luffy only states he'll kick someone's ass after he has a reason too.
  I always saw two reasons behind the power jump. First, CP9 was the strongest group they had ever faced, and forced Luffy, Zoro, and Sanji to become stronger, which I'm sure definitely helped. However, the second reason is that, in order to get Robin back, they had to go through CP9. They couldn't talk to her like in the mansion, nor could they have kicked Blueno off the kart like on the train. Without defeating CP9, they couldn't get Robin back, and so they put everything they had into their battles because there was no other alternative.

A canonical reference is this:

Another point to be noted is that Luffy's new learned techniques of Gear Second and Gear Third make sense because he had been working on new techniques/moves after fighting Aokiji the first time, and Zoro's Asura can also be explained on the basis of the immense training he undergoes on a daily routine. Nami's learned techniques are mostly just various scientific uses of the perfected Clima Tact that she was given by Usopp.

After the events in Skypiea, Usopp upgraded the Clima-Tact into the Perfect Clima-Tact, which was first introduced when Nami and crew were trying to catch up to the Puffing Tom with the Rocket Man. With a better knowledge of Nami's preferences and a handful of Dials to spare, he changed the Clima-Tact from a party toy with a few combat capabilities into lethal weapon capable of amazing weather powers that only Nami could unleash. With this, Nami became fully capable of fighting on her own, and just as superhumanly powerful, in a sense, as any other crew member.

As a side comment on that in the anime luffy even states it that before they were confused and unsure but now they have a goal and will beat them.

@jphager2 I don't remember seeing/reading anything of the sort. Can you point me to the source if you remember?

I agree with the point that they got stronger simply because they had too, they had no alternative.
It's ridiculous the way luffy gets stronger. It's ridiculous and bright at the same time. I remember when Luffy fought Arlong's pet, Mohmoo, he invented a technique based on Genzo's small windmill. Later on Alabasta, he improvised with misu no luffy, in which he covered himself in water to be able to hit Sir Crocodile. On Ennies Lobby he inspired himself in a Steam Engine.

Why couldn't he simply turn into fire and repair the damage?
Spoiler alert, stop reading if you're not past One Piece episode 483.
When the guy (Akainu) put a hole in Ace, why couldn't Ace just turn into his element like all of those elemental Devil Fruit users? I get that magma was able to burn him, but how does that stop him from just dispersing like the other elemental fruit users?

You can read here that:

Users of Busoshoku Haki can strike Logia users as if they were human; Rayleigh describes it as the ability to "force into solidity the fluid bodies of the near-invincible Logia Fruit users" when he explains it. When Haki is applied to a Logia user while they are intangible, rather than nullifying the powers completely; it turns the user back to their physical form. It also allows the one using Haki to grab the person in their transformed state as if they were tangible.

From the manga:

Chapter 597 Page 18.

I think this answer actually doesnt address the situation in question. I dont think Haki was involved at all.

@Viziionary I'm sorry if I didn't help answer your question but to me your question seemed like it was asking "How was Akainu able to hit Ace inspite of Ace being a Logia user?"/"Why couldn't Ace convert to his Fire form to avoid taking damage from Akainu's attack?" rather than "Why wasn't Ace able to heal from Akainu's attack?", and hence this answer. Although now that I read the title again, it makes sense.

Your answer was high quality in terms of citation and explanation, I just wanted to make that comment because not only did I mistake it for being correct because of the pretty graphic, it got 5 votes and the correct answer seems to have even gotten a negative vote once I selected it.

@Viziionary in fairness, I don't have good enough references and the Haki explanation makes alot of sense even though mine does seem to be the canon answer.  I fully understand the downvote and these upvotes.  I should find canon references when I can (which i don't have access to at the moment or when I answered the question).

@Viziionary I can't confirm the fact about it getting a negative vote because I'm on my mobile right now and cannot expand votes, but okay. Anyway, no problem. I'll read the question more carefully next time.

Certain Logia fruits seem to take dominance over other Logia fruits.
By my understanding, a Logia who is struck can still be hurt unless they turn into their element when struck.  Several have learned to do that reflexively. Once damage is done to the user, their Logia fruits have never been shown to be able to heal the damage. They cannot create additional flesh, organs, etc from their element but only revert back to their rest state.
Bushoshoku Haki or sea stone can prevent the user's Logia fruit from taking effect. Those did not happen apparently in this case.  Akainu was able to punch that killer hole in Ace because Ace was trying to defend Luffy.  Akainu attributed the effectiveness to the fact that Magma is superior to Fire.  This has been seen before with some Logia's having specific weaknesses or strengths compared to other elements.  Enel was weak against Rubber.  A small amount of water made the Sand Sand Fruit clump.  Apparently Magma can burn Fire as it is so much hotter.

It is also possible that if Ace will turn to his element just to dodge that punch of Akainu, it will go straight to luffy. That's why instead of dodging it and might hit luffy, he let akainu hit him just to stop the attack.

Correct me if I'm wrong, but Logia fruit users cannot "heal" by simply turnin into their element. They can dodge attacks and are usually immune to Haki-less sword slashes or bullets and the like, but they're not actually taking damage; simply turning into their element to avoid it.
Though even if I'm wrong, Akainu pierced right through Ace's body, causing internal damage as well; if Ace had only received external damage, he might have been able to survive despite his Devil Fruit being inferior to Akainu's, but here, a good deal of his internal organs were fried, so there was no way to heal damage this severe. Not to mention that even if he could turn into his element and heal, he was too weak to do so; Akainu's attack left him with barely enough strength left to speak before he died.

Why was Edo Tensei Madara young, when he had died at an old age?
From Naruto manga and anime, I know that Uchiha Madara died as an old person after he helped Uchiha Obito.
But it was bit weird for me, when Kabuto summoned Uchiha Madara-sama with Edo Tensei, Madara was a younger person.
Again, when Chiyo was summoned, she was older as when she died.
How can it be possible?

You can read here that:

The reincarnated can also have their bodies modified and experimented on. While the technique usually reincarnates one as they were upon death, the reincarnated can also have various points from their life combined to get the best possible results as seen with Madara Uchiha, having been brought back "beyond his prime" despite dying a withered old man. In addition to regaining his physical youth with peak health and combat prowess, he also retained the Wood Release and Rinnegan abilities he had in his old age.

Is Madara's Ten Tails Jinchuriki Mode a complete form?
Since Eight Tails is still outside (in dream) rather than in Gedo Statue, is Madara's Ten Tails Jinchuriki Mode complete?
Update:
I am talking about episode when Madara takes all the beasts into the Gedo statue and become the Sage of Six Paths. The Eight Tails was swapped with one of its tails to escape. As Eight Tails is not completely inside the Gedo statue, how can Madara come to Ten Tails Jinchuriki full form?

@labeo do you mean naruto in total? (also do "which" madara do you mean?) tried to formulate the comment in case you didn't watch the whole of naruto so far (as it seems you didn't).

I am talking about episode when madara takes all the beasts into the gedo statue and become sage of six paths but eight tails was swapped with one of its tail to escape as eight tails is not completely in gedo statue how can madara come to sage of six paths full form

Major correction: the form you are referring to is not the Sage of Six Paths mode. It is the Ten Tails Jinchuriki Mode. I've edited the correction

Yes, Madara's Ten Tails Jinchuriki Mode is complete.
The Gedo Statue drew in all the beasts.
When a Tailed Beast is removed from its host, the host dies. To avoid this from happening, there should be enough chakra of the Tailed Beast left inside the jinchuriki. When Gyuki was being removed, he sectioned one of his tentacles, having chakra, to Bee. This was done so to ensure Bee survives without the majority of Gyuki.

Struggling against its confines, Gyūki apologised to B as it was extracted and sealed within the statue along with the other tailed beasts, but not before cutting off one of its tentacles, letting B survive through the chakra within it.

Therefore, the majority of Gyuki was absorbed into the statue and only a portion of it was intact with Bee. That portion served as a source of life for Bee and it was negligible compared to the intake of Eight Tails chakra into the statue.
Therefore, since the statue contained most of the Eight Tails chakra, Madara was able to undergo the transformation.

But half of nine tails is in naruto right?

Yes, first time Yang Kurama was sealed into Naruto. Then, when Yang Kurama was removed, Yin Kurama was sealed into Naruto from Minato.

So half can be considered as a measurable amount of chakra to tell that madara's ten tails form is not perfect?

To become the Ten Tails Jinchuriki, all you need is a considerable amount of chakra of the Tailed Beasts sealed into the Ten Tails. The question of excess or less doesn't seem to concern the jinchuriki form, as we can see that Obito was able to undergo the transformation even without the complete chakra of Kurama and Gyuki

How does the Devil Fruit user know how to activate their power?
For some Paramecia type, to use their power, they must do something with parts of their body.
Just like how Bartholomew must cross his finger to create a barrier, or Foxy must stick his thumb, middle, and ring finger together to create Noro Noro beam.
But how can they know that crossing or sticking three of their fingers will activate their powers?

Now your question makes me curious - How come Law came to know about his power - we have seen him struggling when he ate the devil fruit

I think they are just there to show that now they gonna use their power like shouting the name of technique and to activate they learn and practice and master themselves.

@exexzian well, yeah, thats also the reason I'm asking about this question by the way.

@mirroroftruth yeah, if the power is just like Luffy or Buggy I think I can understand, but for other Paramecia that must have some condition to active their power, that is what I'm not understand here. Like I said, Bartholomew or Foxy, I never seen their power active without crossing or sticking three of their fingers right?

I am not 100% sure but crossing finger, hand are just to show and to know about power they will be aware as soon as they eat the devil fruit but need time and training to use it properly

Maybe the same way Spiderman learned. He just accidentally put his fingers that way and super natural stuff happend.

@exexzian the devil fruit user will know as soon as he eats the fruit

@mirroroftruth I doubt on that.. We have seen law trying random things to use his power - moreover he wasn't even sure of what does his devil fruit does in actual

@mirroroftruth however I do consider your earlier comment to be reliable they learn and practice and master themselves

@exexzian that might be right, know that they power but don't know what they are.

@SirDuckduck lol, that's also what i'm thinking

There seem to be 3 different ways to learn this:

Experimentation

If a user has no idea exactly how his fruit can be used, he can play around with different motions movements or just live his life.  Brook never figured out what his fruit could do until he was already dead.  Hypothetically, Bartolomeo could have lived his life without finding out if he hadn't happened to cross his fingers the right way (assuming that is required).

Reason

Some users have some idea what their fruit is when they eat it. Others only have partial knowledge of their abilities. The Barrier Fruit is based off a children's game. If Bartolomeo knew that he had this fruit, they could have tried to enact that game to see if it worked.  This can be combined with experimentation to improve fruits.  Bartholomew Kuma and Law seem to have decided to try appying their abilities to abstract concepts and studied their ability to learn how to do this.  Other fruits may have simular unusual uses that are never noticed as the users aren't as smart as those two.

Historical Research

Devil Fruits are not single use.  They are reincarnated into a new fruit to be eaten when the user dies.  This means, for instance, that Law knew exactly what fruit he had before he knew how to use it. There are records and second/third hand sources stating what some fruits can do. That is exactly why he knows that you can make someone immortal with it despite having never done so.  For our repeated example, Bartolomeo might know he has to cross his fingers because he could have read that it was required.  This means, of course, that someone else must have learned it by on of the first two methods and there may be other unknown uses.

Final Note

Devil Fruits do not change during the person's life (with Brook as the possible exception).  A Logia fruit does not itself get stronger as the user does but the user can get more creative, more practiced, and more experienced in combat in general. This means that training can't make the fruit itself more powerful or generate new powers that previously were impossible (only undiscovered).

I think the Historical Research and Experimentation are make sense for me, and the Reason point I think it's only for few Fruit, but of course This can be combined with experimentation to improve fruits. Thanks for explanation @kaine nice one!

@JTR actually it works for most. Luffy invented his Gears, Brook: water running and others, Robin: giganto stuff, and (best of all) chopper learned how to make 4 more forms tha other zoan and a drug which facilitates that. These are all creative uses.  It doesnt work if they dont know the power somewhat first.

for improving their power maybe true, but I mean when they really have no idea how to use the power at the first time they ate it. Not all Paramecia (mostly) know how to active their power even they know what kind of fruit that they eat right? they must research and make an experiment just like you said. Luffy already know he's a rubber man when he's kid, later he improve his power.

I think devil fruit users has no specific way of activating their power rather than training and practice. They discover it by their own because as we can see on each devil fruit users learns new techniques after they train hard using their ability.
We don't exactly know the story of other fruit users how they discovered to activate their powers but we can make Luffy as an example because from the start we have seen his story.
After Luffy became a rubber man when he was still a kid he doesn't know how to activate his ability. But through his every day training and challenge to defeat his brother Ace he created and discovered his very first technique Gomu Gomu no Pistol. And created more techniques as he discover more ways to use his ability. Another example is his Second Gear before he needs to sit to activate it but later after training and practice even standing he can activate it.
As for Bartholomew and Foxy since we haven't seen their story we can assume that they also discovered it through the same process or accidentally discovered it. They did a lot of tests to discover a more effective way to use their power. For example Foxy might discovered that when he stick his thumb, middle, and ring finger together his Noro Noro Beam last longer than using only one of his finger. The same as Bartholomew, he might discovered it through practice that crossing his finger creates a stronger barrier than just one finger.
Another good example is Flamingo. He only discovered and learned his awaken through training and practice.
So activating their power depends on what they discover from themselves of what they are capable to do and refine it throug training and practice.

Activating the ability of Devil Fruit that I mean is like Bartolomew and Foxy, not like Luffy, when  he's still a kid, he already know that he's a rubber man and later he can improver his power. But Bartolomew and foxy when first time eat the fruits, I think they have no idea what the power they have.

By the way, for if true that Foxy are "accidentally" sticking three of his finger, I think he's really stupid. lol. Well, maybe that's true and make sense for Bartolomew when he crossing finger then the Barrier is activate

@JTR we can't assume that Bartolomew and Foxy doesn't know about their fruit because its not shown in manga. They might or might not be.

@JTR about Foxy we'll we never know how he discover how to use his power its just a speculation that he accidentally discover how to use it and after all he is stupid anyway. lol.. but I like the guys answer above its better..

yeah I know, but maybe Foxy is best example to what SirDuckDuck comment in my question about how spiderman learned his power lol.

I think if you eat a Devil Fruit and don't know what the power is, you can discover it by accident or when you're in danger. But there is one thing you will know you ate a Devil Fruit: because they taste horrible.

If Kurama is the living embodiment of hatred, then what about the other Tailed Beasts?
If Kurama is really the living embodiment of hatred (not some self proclaim title), then what about the other Tailed Beasts? Are they the embodiment of something else?

Who said that he was the embodiment of hatred? I've read the wiki but I can't find anywhere that says that.

As per naruto.wikia.com

Long years of receiving humanity's negative treatment caused Kurama to
  develop intense hostility and distrust against them, even going as far
  as proclaiming itself to be the living embodiment of hatred.

So, he was not embodiment of hatred by itself from start but became like this later on. So its not a tailed beast characteristic to represent as embodiment of single emotion per tailed beast.

This is what i also thought to be true. Not only with kurama but also shukaku who is related to the fear in Gaara ... hmm

Was Naruto controlled by the Nine Tailed Fox?
In the anime (Episode 133), when Naruto turns into the Nine Tailed Fox for the first time during his fight with Sasuke, Sasuke comments that the chakra has its own mind.
Was he controlled by the beast or was it the other way round?

Which episode...?

@AnkitSharma its from episode 133 I guess.

As far as I know (which is not so much by the way), Naruto indeed was controlled by the Nine Tailed Fox, because the first time he was able to control himself and come back from his evil and destructive possession was during his fight with Pein.

@SayantanSantra first of all, Naruto was NOT able to control himself, his dad just closed the seal to stop Kyuubi.

During his fight with Sasuke Naruto is seen to be in his Version 1 of the Nine Tails cloak. According to the Naruto Wiki, Naruto has very little control over his actions. It is not until he enters the Version 2 form of the Nine Tails cloak that he loses complete control.
This is Naruto during the fight with Sasuke at The Valley of the End in the Version 1 form:

This is the Version 2 form where he loses complete control:

In Version 1 transformations, Naruto had only the briefest of control
  of his own actions. If he fell deeper into a rage, Naruto could slip
  into Version 2, losing himself to Kurama's negative influence and
  going berserk, requiring outside help to suppress the fox's
  chakra.

the frequency of Naruto going nine tails mode increases in shippuden. He loses control easily. Why?

I wouldn't say that he loses control easily. He only loses control during tough fights like against Pain or Orochimaru.

I think he is not controlled by the kyuubi, he just loses his mind for the rage, like anyone that gets really really angry. Kyuubi just speeds up the process of getting angry and will take control over Naruto just after he gets the nine tailed and complete kyuubi's form.

What is Shanks' sword made of?
At Marineford, Shanks stopped Akainu with his sword. That much we all saw, but what I noticed was that he did not use Haki on the sword and yet it did  not melt.
This has been bugging me. How is this  possible, if Akainu's Lava can burn even fire but not melt the sword which is not even infused with Haki.

How can you confirm that he did not use haki?

Cuz it did not turn black color. That was my doubt

check this also, http://anime.stackexchange.com/a/13277/6345

This was same pretty much same  as @solalito 's answer and I can agree on it

yes they are but your question needs a bit more specific information including those information.

The black coloring induced by Haki was only introduced after the timeskip. Before that, when Haki is used, it is not visible with two exceptions: Garp's punch at Enies Lobby and Whitebeard's fist at Marineford.
For example, in chapter 512, Rayleigh faces Kizaru in a sword duel. Rayleigh is using a simple sword while the admiral is wielding an energy sword made of pure light. In this fight, for Rayleigh's sword to be effective against Kizaru, he is obviously using Haki, even if the Haki is not visible at all. This is confirmed by the fact that Rayleigh's sword swing injures Kizaru, a logia user.
Therefore, Shanks' sword is not "made" of anything special (i.e. seastone), he was simply embedding it with Haki. He may be wielding one of the world's great swords but this has yet to be confirmed.

This looks very plausible and makes the  most sense. One last question though. If Black Color for Haki was introduced only after timeskip, why is that Hawkeye's sword is shown in black because during  training zoro, he did  indirectly confirm that his sword is black because of haki by saying, "If you  learn to master haki, your sword will not have a clinks" or something like that

Mihawk's sword is called Yoru. It is one of the twelve Supreme Grade Sword and it is also a black sword. So black is its natural color

.
I was confused by this. Re-read it. It says a black sword and not "the" black sword, referring to his. makes sense now.
Thanks. :)

If Mihawk's blade was black to begin with, would you see a difference if it was induced with Haki? I think not. I may be wrong though.

@KRISHNAKANTMISHRA check out chapter 51, Zorro's first encounter with Mihawk. Mihawk's sword blade is black even before he takes it out. You need to make physical contact with an object in order to infuse Haki in it.

It is better to ask another question then ask in comment, you will get more detailed answer and will help others who want to know about it

This was a really well thought out answer. The whole black coating for busoshoku didn't occur until after time skip. There are mentions of haki usage and even demonstrations of it earlier in the series though it isn't shown in  that level of detail. Great question, great answer, kudos.

I believe the glove is used when fighting special logia types like Akainu and Ace because normally if you try to punch Akainu you're bound to get burned but when using the black glove you can protect yourself from the magma.
I believe that the black glove was not only made after the time skip because during Zorros training the king monkeys sword was not black and it was said that he copied the sword from Mihawk

Why did Orochimaru go for Sasuke instead of Naruto?
During the second test of the Chunin exams, Orochimaru goes for Sasuke and even gives him power. But why does he avoid cursing Naruto like he did to Sasuke? Wasn't Naruto as powerful as Sasuke? Or was he too powerful to be controlled?
Also, why does he use the Five Elements Seal on Naruto?

The main reason why Orochimaru wanted Sasuke rather than Naruto, was Itachi Uchiha.
Sasuke Uchiha, was developing into the prodigy that his elder brother Itachi was. Orochimaru had experienced Itachi's power first hand. And it proved too great for him.
Another reason, was the Uchiha clan's famed Sharingan. Itachi's prowess with his Sharingan was outstanding. Orochimaru expected the same from Sasuke.
Since Orochimaru couldn't take control of Itachi's body, he decided to settle for his younger brother's.
As to why Naruto wasn't chosen, Orochimaru favoured Sasuke over Naruto. Because at that time, Naruto was at the back of the class, and Sasuke was the Uchiha prodigy. Also, the fact that Sasuke is Sharingan abled and Itachi's brother, outweighed Naruto's overall.
The two reasons as to why Orochimaru used the Five Elements Seal:

He wanted to disallow Naruto from using the Kyubi's chakra.
And to tamper his control over his own chakra.

Did Orochimaru fear the nine tails power? Otherwise, why did he seal it? He could have simply avoided naruto.

@AdityaDev: At their first meeting, Naruto was interrupting Orochimaru's observations and testing on Sasuke. To keep him from disturbing, he used the seal. Since the Nine-Tails' chakra always presents itself into Naruto's usage, Oro decided that the 5 Elements seal was best.

Orochimaru was actually going after Itachi, Sasuke's older brother. After he failed on getting Itachi's body he decided to get his youngest brother, Sasuke, because he was going to be an easier target.
The main reason why he even targeted Itachi was because of his Sharingan. He was going after a Kekkei Genkai, which is a special ability that not a lot of people can have, that his next vessel will have to make him stronger. He did not target Naruto because he doesn't have a Kekkei Genkai.
He put the Five Elements Seal on Naruto like that he would not use the Kyuubi's chakra and his own.

I would say there are two main reasons why Orochimaru went after Sasuke.

Orochimaru wanted Sasuke or Itachi's eyes. After all Orochimaru was researching inherited chakra or called Kekkei Genkai. Meaning you must be born into that specific clan to gain the chakra or special features of it. Orochimaru was only looking for special Kekkei Genkai. Here's a few examples: Shikotsumyaku clan and their ability to using their bones in their bodies as weapons. User Kimimaru. Crystal release nature chakra users are able to materialize and use crystals. Finally Jugo's clan Kekkei Genkai. Allowing them to absorb natural energy into their own bodies and use it. This interest in Kekkei Genkai caused him to desire one for his vessel. So when Itachi showed him the potential in the Sharingan. He immediately desired to control and use it.
Orochimaru could not use him a vessel. A) Naruto is not easily controlled and brainwashed exceptionally when it involves someone close to him. He would have sliced off his own hand before intentionally hurting a loved one. B) He is the Jinchuriki. Kurama or the nine tails fox would have never allowed the snake to stay in Naruto's mind for long. He or she would have knocked some sense into the boy long ago. C) His loyalty to the village. Orochimaru needed someone who has nothing and no one holding him back. Sasuke had no loyalty to the village and the only thing holding him back was somewhat friend Naruto. While Naruto was very loyal to his village and was gaining friends. Causing Naruto to not need him unlike Sasuke who desired for more power which Orochimaru happily supplied for him.

Why is the anime named "Baccano!"?
The question itself is self-explanatory!
What's the meaning of it?
And why is it named so?
How was the anime named so?
I thought the reason would be revealed by the end if the anime but it didn't, and I'm left here wondering...

As the English Wikipedia article states, Baccano [bakˈkaːno] is simply Italian for "ruckus, row, din".
As far as I remember the story is never set in Italy, however the Mafia-like organizations featured in the Anime are likely what makes the connection here and you will probably agree that there is quite a bit of "ruckus" going on,

Not to mention a bunch of "Italian" names (and a "Slavic" one or two for good measure).

It's called that because the book was. In the actual novel, The Narrator title drops the series in the second chapter, referring to events of 1930 (specifically the tale about the Liquor of Immortality) as a baccano (ruckus) when recounting the tale to a Japanese tourist in 2002 while they're waiting for Ronnie to recover a camera stolen by the Splot gang.
As for name itself, Narita had been watching some gangster flicks and got inspired to write a story about it with a few twists, and it ended up becoming a twisted tale of various subplots intertwining and colliding upon reaching the conclusion, and felt that the word baccano was an accurate descriptor of it while also fitting with the Mafia theme.

Some sources/references would be good to backup the answer :)

Why did Kakashi's Sharingan fade after Obito died?
In Chapter 691, after Obito died, Kakashi’s Sharingan faded. Why is it that Kakashi's Sharingan faded, while the Sharingan Danzo had stolen from Shisui and the one Shisui had given Itachi, were still okay even after its original owner had died?

Both Kakashi and Danzou had physically obtained their Sharingan via transplantation.
During the finale of the Fourth Shinobi World War, Madara rips Kakashi's Sharingan and transplants as his left eye (Chapter 674).
Naruto, using Hagaromo's power, creates a normal eye for Kakashi (Chapter 675).
From Naruto Wikia article on Kakashi Hatake, merged plot summary of Chapter 686, 687 and 688 (emphasis mine):

Prepared to give his life to lend what little assistance he can, Kakashi stands in front of Sasuke to take the attack while Obito does the same for Naruto. Although they are unified in their willingness to die, Obito decides it's too soon for Kakashi and uses Kamui on the attack bound for him, leaving Obito unable to save himself. Obito's body dissolves, but his spirit returns shortly afterwards and inhabits Kakashi. Obito feels that Kakashi will become the next Hokage and wishes to reward him: a temporary moment of having two Mangekyō Sharingan.

Obito gave Kakashi the privilege of having both Sharingan (Mangekyou) temporarily. This was the doing of the spirit of Obito and not the physical self. Hence the Sharingan Kakashi used was spiritually influenced.
Later, when Kaguya is defeated, Obito's spirit leaves Kakashi's side to join the other world. Because of the spirit leaving, the Sharingan also disappears along with it.
Had the Sharingan been physically present, it would have stayed, just like Danzou, the Kotoamatsukami crow and pre-war Kakashi.

Sharingan that have been transplanted unto someone will never fade, even if the original user dies, as was the case with Danzo/Shisui. The original Sharingan that Kakashi had recieved wouldn't have faded either.
However, in chapter 674, Madara steals Kakashi's Sharingan. Kakashi doesn't regain the Sharingan afterwards.
In chapter 686, after Obito sacrifices himself to save both Naruto and Sasuke, his body dies, but his spirit is still alive and it inhabits Kakashi, leading him to gain two Mangekyo Sharingan.
After Kaguya's incapacitation, as Obito's spirit disperses, so does the Sharingan.

then why DANZO have so many sharingan on his body ?
i doubt any uchiha spirit want to be inside an old man that ordering their massacre

Basically, Obito dies when he attempts to save Naruto and Sasuke, but his spirit was still there, even though his original(physical) body had left the world. Now the spirit Obito grants Kakashi 2 spirit MS, which disappear after Kaguya was sealed away and Obito's spirit leaves the world. If Obito were to give kakashi his MS while he was alive, Kakashi could have kept the Sharingans even after the war. As for the original Sharingan Kakashi had, Madara snatched it out of Kakashi's eye socket(gross)...

How can two pucks be used at the same time in air hockey?

As we can see, there are two pucks on a single hockey table. They collide and goal. It doesn't look like one came flying from another table. As I know there will be only one puck in a single game on a table. So what is going on in this part? Does air hockey have different gameplay rules in Japan?
What is really going on here? Can someone explain about two pucks at once on a single table?

It's possible. I have seen a table where multiple pucks rain down to the field towards the end of the game, though the table depicted in the manga page doesn't look similar. Anyway, I don't think it's strange to get a puck from somewhere and play them on a single table.

Air hockey in arcades is not always regulation, and can get a bit crazy at times: https://www.youtube.com/watch?v=6hP7OZrczss

I know when I was small we would play with 2 because it was too easy to defend your slot with only one puck on the table.

A typical air hockey match consists of using two pushers and one puck. And as @jphager2 suggests in his comment, there's no need for a net in an air hockey match, hence, it could be a multi-purpose table.
So what's the deal with two pucks? Now, in that Chapter, Raku and Chitoge had a lot of fun in the arcade. And the bill had to be a decent amount. So instead of someone willingly agreeing to pay the bill, they keep a match on condition that the loser has to pay for all the games.
Since the the stakes were high, it is most likely that they used two pucks to increase the difficulty of the game.
Edit:
Like @mirroroftruth says in their comment, the two pucks could also be a symbolic representation of Raku and Chitoge themselves. No matter how much they try to distance themselves, they always end up coming together.

I did thought about this, i had 2 thoughts, 1 is about the difficulty level, as you state to increase the difficulty level, loser is going to play all the expenses so it would be interesting to have 2 puck and another is for the plot, as we can see, they meet each other how much they try to stay away from each other, lots of coincidence, so to end in similar manner two puck would play important role than 1 puck, so two puck were  used. This is what i think.

@mirroroftruth Yeah. I had thought about it too. But then I felt you were asking for factual details related to the game itself and not anything deep into the story. The two pucks relate their situation

ya, 1st i wanted to confirm about the game, as reading above, two pucks are possible, the reason i thought were also valid, if you don't mind then you can add it in your answer and i will accept it

@mirroroftruth: edited the answer :) (sorry it took so long)

What is meaning of "Brush Your Teeth. -- Unripe Fruit" in Hunter x Hunter?
At the beginning of the Hunterpedia segments at the end of episodes of the 2011 Heaven's Arena arc, the opening image contains the English text:

Brush Your Teeth.
Unripe Fruit

The rest of the writing is in Japanese, I assume there is some sort of inside joke.  Can anyone provide a context for those two lines?

Those two lines are subtitles, not present in the original video. "Brush Your Teeth" is a translation of the blue text immediately to the left of Killua's head. "Unripe Fruit" is a translation of the green text in the lower left, above the drawing of an apple. I suspect it's just random writing. (But then again, I don't know anything about HxH.)

Thanks -- should have guessed that the lines might be translations.  I still think that there might be some sort of context there which is zooming right over my head.  If you like anime, check out HxH.  While starting out as typical Shōnen, the strong characterization and deeper plots and themes add up to something really good.

I may have the phrases figured out.  Initially I was extra confused as to why there would be such out-of-context English phrases printed in a Japanese anime.  Senshin cleared that up, and I realized everyone could read the text.
I've now watched some of the original 1999 Hunter x Hunter anime series.  In those, the psychotic villain (and sometimes ally) Hisoka occasionally refers to Gon as "unripe fruit".  (I do not believe he ever says that in the 2011 version.)  The context is, even though Hisoka feels sorely tempted, it is too early to destroy Gon (and perhaps Killua) now.  He is like unripe fruit, and it will be much more enjoyable to destroy the boy mentally and physically once Gon is older and gained significant skill.
Knowing that everyone can read "brush your teeth" helped me see the image afresh.  I thought Killua was just smiling, but now I see it is a huge, clenched-teeth smile.  Plus his right hand seems to be grasping an invisible tooth brush and motioning as if demonstrating proper tooth brushing technique.  The "Hunterpedia" environment is being presented as a classroom.
The one remaining puzzle is why Gon's left hand seems to be motioning as well.

I'll do that, Ashish.  Now I am rewatching some of the 2011 HxH.  It turns out Hisoka did use the term "unripe fruit".  In reference to accepting a deal with 2 other young protagonists, Kurapika and Leorio, Hisoka says (to himself) "Why must unripe fruit be so tantalizing?"

Yeah, seems about right for someone like Hisoka to say. Feel free to edit that in your answer.

'Brush your teeth': it's also (I think) something a parent would say quite commonly to a child in Japan. Combined with the ai-ai-gasa in the corner, I would think it's a collection of classroom doodles.

'Brush your teeth' is for Killua (so it is blue) and 'Unripe Fruit' is for Gon (so it is green).
Killua is such a great sweet tooth. 'Brush your teeth' is meant for Killua. I don't think he has ever brushed his teeth. Or even if he has, (just like a parent does) he is just told to put more effort on his brushing.

What disease did Kenshin and Kaoru catch that killed them?
In the OVA Rurouni Kenshin : Seisouhen, there was a scene where Sanosuke and Kenshin met each other again after a few years. Sanosuke tossed Kenshin a grilled fish on a stick and Kenshin wasn't able to catch it showing that the disease had slowed his speed and reaction time severely.
Kaoru seemed to have caught the disease from Kenshin after spending a night together which means it's some kind of an STD.
Is there any disease that's similar to the aforementioned, in real life?

I found this on the Wikipedia page for Rurouni Kenshin: Reflection

Kenshin eventually becomes ravaged by an unknown disease that is much
  like leprosy (the writers have admitted there is no medical
  explanation for Kenshin's condition[citation needed]). To share his
  pain, Kaoru convinces Kenshin to infect her with the disease through
  sexual intercourse.

Leprosy is not an std but can be spread through physical contact with a person who is infected.  Since it is said that the disease is much like leprosy it could have been transmitted to her when she stayed with him.
As far as canonicity the story was not written by Nobuhiro Watsuki. I'm not sure if this story was considered canon or not but the following is a quote from the Wikipedia

Although Samurai X: Reflection was not written by Watsuki, he stated that he "checked in on the script."[5] Watsuki mentioned not having input in it, and let the director "run wild with it." In response to Kenshin's death in comparison to the happy ending in the manga version, he felt that his own work eventually would have reached Kenshin's death had he continued writing. He had not wished to pursue that line because "Kenshin went through so much crap and deserved a happy ending." He felt that neither version was better than the other because "it's a personal taste thing."[5]

Can you talk about the canonicity of the OVAs?

After everything he had been through, it seemed unfair to him died like that. It's just so tragic. T_T

What about Meningococcal disease? It makes skin get purple and it was deadly in the 1880's until penicilin was discoverd in 1945. Here the link, it's spreaded for spending time in the same room with a person who s sick of this https://en.wikipedia.org/wiki/Meningococcal_disease

Can you explain why you think this disease is the answer, given that it doesn't seem to match the description given in the question?

Why does Obito look like an adult during the Kyuubi attack on Konoha?
In the series, it is stated that Kakashi was 26 when he became the leader of Naruto's squad. So following that, he was 14 when the Kyuubi attacked the village. Seeing that Obito was the same age as Kakashi, he should be 14 but he didn't look like it. How old was Obito at that time? It shows him as an grown up, adult man. Is this because of Zetsu covering him or is he just older than Kakashi?
This is not a question directly about the age of Obito but also why he looked older. In my understanding Kakashi and Obito are about the same age. I don't care when Kakashi became a Jounin because that is not relevant to this question.

You can't judge someone's age by looking at their height.He could of just had a massive growth spurt in the past year before he attacked konoha.Obito and kakashi are the same age.Obito's just a few months older.But kakashi is just a short kid who acts older than obito.

I can't believe people doesn't know why. He was wearing white zetsu which makes him look bigger. Go read the manga!

The difference in age between Obito and Kakashi has been explained in this answer.
From this thread on narutoforums (emphasis mine):

It is impossible for both Kakashi and Obito to have been 13 during the Kakashi Gaiden, because there is at least a confirmed 4 year age difference between Kakashi and Obito when they were confirmed to both be Genin teammates during the Chuunin Exams. They entered the academy the same time, and they all graduated the academy together as teammates. Kakashi was at least 4 years younger than both of his teammates at all times. There is no possible way that Kakashi was a 13 year old Jonin during the Kakashi Gaiden.

Since Kakashi is younger than Obito, obviously Obito will look older.

That isn't completely right. We have clearly seen Kakashi's backstory in the anime. There we see that Obito and Kakashi many times together, especially at Kannabi bridge. They both appear to be of the same height. Kakashi was about 12-13 at that time. If Obito was actually 4 years older than him, then he should have been taller than him. I myself don't know the answer, but I know that the hypothesis given by Ero Sennin isn't completely right.

It is quite unclear how you can judge a character's age just by looking at their height. Height doesn't necessarily correlate with age. And analysing height alone, you can't just declare an answer.I derived my answer using the facts provided from the series. If you can pinpoint which of it is incorrect, I'll be happy to correct or withdraw my answer.

It is just a guess but the looks could have been different because of the zetsu thingy attached to obitos body. Maybe he made the zetsu part appear more adult like to misguide any possible connection any of his former friends may find in his behavior if he ran into them. Judging by how long he observed kushinas pregnancy and waited for the opportunity , it is possible that he considered more than several scenarios of the attack. but again it is just a guess.

Although it seems like that could be true and considering he became chuunin and jounin at such a young might mean that. But from my understanding Kakashi must of just been a really strong and smart ninja. But considering that Rin, Obito and Kakashi were in the academy at the same time and how Kakashi easily knew the rules from the top of his head might just means he is the same age but just smarter.
Its the same with Sasuke. Anyone can say his age is 4 years younger than Naruto but it would not add up. I just think that Kakashi is the same age, short, and may just talk smack about Obito.
He could very well be 4 years younger but there's just not enough evidence to support that. Although its very smart to assume that he is younger because just because they are in the same cell does not mean they are the same age.

Why is it that Beerus and Whis know Frieza but not Buu?
It's a known fact that Beerus was asleep for 38/39 years.
When he wakes up, Whis tells him that a Saiyan defeated Frieza.
I know 39 years is a long time however Buu was also on rampage throughout the universe way before that (fighting the Supreme Kaihous and so on).
How come they know about Frieza and don't know about Buu?

Well, more importantly, how come they don't know Buu despite the fight between Goku and Buu happens after Frieza's defeat. And what about Cell?

Cell is just an "earthling" villain

@SakuraiTomoko Probably for the same reason Beerus doesn't know about Goku. They're insignificant to him and don't interfere with his role as  the god of destruction.

Dragon Ball Super has some giant plot holes in this area.  Most notably, about how Old Kai has to tell the Supreme Kai who Beerus is despite the fact that Beerus is active every 50 years, and Supreme Kai fought Buu a really really long time ago(most definitely more than 50 years ago)

Even I have this question all the time and am desperately looking for this answer. Why Beerus did not kill Buu when Buu was on rampage? Krikara said, "It's possible that Beerus didn't need to seek Buu for a challenge if he was already stronger than him." But even if Buu was not a challenge, he though was a threat to him. If Buu kills the Supreme Kai, Beerus dies too.

In Dragon Ball Super, as well as Battle of the Gods, Beerus did not know about Majin Buu. The manga has not given a definitive answer as to why they don't know each other, but we can narrow down the potential answers.
In an interview, Akira Toriyama has stated that contrary to Supreme Kai's statement about Bibidi creating Buu, Buu has actually been around since the beginning of time. Bibidi just knew how to wake up Buu from his long slumber.
We also know that gods aren't born as gods in Dragon Ball. They obtain the god title after training and fulfilling their duties. Thus we know that Buu existed before Beerus became a god.
This means that Beerus not knowing Buu can be attributed to any of the possibilities below -

Beerus and Buu never met each other - possible due to the excessive amount of time they spend asleep.
Beerus might have met Buu, but in kid Buu form. He has never seen Mr. Buu before.
There was no reason to meet. Beerus destroys planets to maintain the balance of the universe. With Buu also destroying planets, he essentially did Beerus' job for him.

We also know that Beerus sealed Old Supreme Kai into that sword. During that time, Buu was also asleep, so there was no chance for Beerus to meet Buu during that time.
We should also note that Old Kai described Buu as more evil than Beerus while Beerus was more powerful than Buu. It's possible that Beerus didn't need to seek Buu for a challenge if he was already stronger than him.

How about Whis?

@Luffy Unfortunately, even less is known about Whis, despite his being Beerus' master.

Maybe beerus did know buu just didn't care about him only wanted pudding plus there's no real way to destroy buu so they could have met before and that's the reason buu didn't want to share his pudding cups, buu isn't really that self-centered, beerus could have beaten buu to a pulp once upon a time and that's how bibidi discovers him or beerus could have delegated his destroying responsibilities to him but I c this unlikely because kid buu seems unruly, proof that they met I believe is in the fact beerus knew to block his candy beam probably because he seen it before or it was used on him and also beerus is forgetful, all the ancient people n the universe knew buu and feared him and beerus from king cold to the kias

Majin Buu or Kid Buu was stronger than Beerus 75 million years ago, so even if Beerus knew about him, he'd be helpless against him. Beerus attained his strength by training with Whis for 75-85 million years.

It is possible that they have met before.  And you who are saying Buu is indestructible, he kind of is.  If they battled for millions of years, eventually Buu would win.  Remember when Beerus fought Goku, used one super move, and then after that he had run out of energy.  If Buu, and I am talking kid Buu, has instant transmission, he could teleport away and have Beerus without any energy left.  Goku only did not teleport away because then it would have hit the Earth.  Kid Buu could not have cared less about if the Earth or any planet was destroyed. He destroys planets.

SSJ3 Goku was fighting on par with kid buu but got one shot by Beerus who didn't even break a sweat. I think it's safe to say Beerus could have completely destroyed kid Buu in an instant, as he did with Zamasu.

Can Sasuke use his Rinnegan to bring Jiraiya and Itachi back to life?
After achieving both Rinnegan and Sharingan in his left eye, can Sasuke use Rinne Rebirth Jutsu to bring Jiraiya and Itachi back to life?

If you are talking about Gedō — Rinne Tensei no Jutsu, then there are some restrictions:

First of all you need the body of the dead person

To perform this technique, the user summons the King of Hell, which then releases the souls of the deceased from its mouth. With their rejuvenated bodies acting as an anchor, the deceased individuals' souls are able to leave even the crossroad between life and the afterlife, returning back to their physical vessels.

The person who used the jutsu dies

Ultimately, once the technique is finished, the user inevitably dies.

I don't know about Itachi's body, but Jiraiya's was lost that even Kabuto was unable to find it.

May be Jiraya is alive.But even after using the justu is Sasuke dies then Naruto can save him

Why did you revert my edit? You are essentially quoting from the wiki, so you have to cite the source.

Plot twist: Naruto dies in the end, Sasuke revives him and dies himself. (I didn't watch much naruto.)

@nhahtdh I reverted your edit because all you've edited was the name of the jutsu and one grammatical error (i'm not native english speaker). In rest you simply deleted what I wrote and added EXACTLY the same text.

@Kira-TheGod: You should look at the markdown diff. I'm only formatting the quotes (indent it in along with the bullet point) and the name of the jutsu. The normal diff is misleading, since the indentation causes change in the HTML structure of the post, which results in a significant visual difference.

Why is it that they die when that jutsu is used. Konan notes "if he uses it now at these chakra levels" in one translation, as in he did not have enough chakra to use it, but he did and died, presumably of chakra exhaustion like kakashi had just done. just a page earlier, she also said that a master of the six paths controls life and death, noting nothing about sacrifice to do so. Plus obito lived after using it, with his only drawback being the same as it was before using it, inability to move due to 10 tails extraction.

Jiraiya most likely did not die from the pains all stabbing and beating him. He was still able to move and talk and it was probably most likely that he died from the pressure of the ocean. It would be quite difficult to retrieve his body or at least what may have been left of it considering there are many things that could have happened to it.

Yes he can use this technique
.but  he  needs their  bodies  and  I think  he  can  escape  death  if he  uses  the  power  of  all tailed  beast  that  Naruto  has or the  ten tails since  they posses  immeasurable  amount  of chakra,as for  jiraya  that's  impossible  because  his  body  is not available.

Is there any official list of people that Zoro had captured or killed as a pirate hunter?
I am wondering, since we all knew from the beginning when Zoro appears in the OP world, he was known as a "Bounty hunter" sometimes called "Pirate hunter Zoro".
Is there any official list of individuals that Zoro had captured or killed when he had that title?

I don't believe they ever released such a list.

His title is fictional as well, is that so?

Not sure what you mean with that, but if you can expand on it a bit. You could ask it as a new question.

Specifically, I want to know the People zoro had captured/killed (pirates perhaps) when he was not in the mugiwara's crew. Since he was said to be a famous pirate hunter, and thus I'm wondering what makes him famous? If he had kill/captured a high bounty pirate then that would do.

I was reffering to your title comment. As for your question, see my answer

I'm sure this guy counts but don't know his name.  Sorry that it is a youtube link. https://www.youtube.com/watch?v=h-6GfNznc2I

No, there is no known list of pirates Zoro captured or killed during his pirate hunter period. The only known one would be Mr. 7

Zoro learned of Dracule "Hawk-Eye" Mihawk, who currently holds the title of the Greatest Swordsman in the world. He set off to sea, searching for him in order to challenge him to a duel. However, he lost his way, and could not find his way back home. In order to survive on his own, he took on bounties to pay for living expenses. He quickly built a famous reputation for himself as a "Pirate Hunter" in East Blue and even in Grand Line as Baroque Works had heard about him; he was even considered the greatest swordsman of East Blue, after which he met the two bounty hunters, Johnny and Yosaku.
Because of his reputation as a bounty hunter, Zoro was offered a position as a numbered agent within the Baroque Works. He replied with that he would accept only on the condition that he would lead the organization (which they refused). He then killed Mr. 7, the agent who offered him the position, to defend himself. - One Piece Wiki

Was Luffy able to activate/experience Kenbunshoku Haki in the War of the Best?
In Episode 470, Luffy feels as if both his hands got cut by Mihawk's sword. And then immediatly after that, feeling he stopped that attack.
So, is it possible that it was the first time Luffy had experienced/activated the Kenbunshoku Haki?

It might be, but it was never confirmed. Mihawk just called Luffy "clearheaded", but in retrospect there is a big probability of it being Haki.

From the One Piece Wikia article on Kenbunshoku Haki:

The first time it was seen being used and referred to as Haki was
  during Luffy's battle on Amazon Lily with the Boa Sisters. Later,
  Rayleigh explained Haki to Luffy and confirmed that "Mantra" is the
  Skypiean name for the ability.

How many people have worn the straw hat, if only for a second?
How many people have worn Luffy's straw hat? Canon, confirmed, and on the head (I'm counting Robin even if she wore it atop of her other cowboy hat).

Here you can read who had worn the straw hat and what it has gone through during the series. I will summarize the list here and add proof from the manga. For the complete panel the thumbnails are cut from, click the thumbnails. Until chapter 801,  it seems 7 people were seen wearing the hat.

Chapter 2 − Monkey D. Luffy

Luffy is the current holder of the straw hat.

Chapter 1 − Shanks

He gave it to Luffy as a young boy after he said the same words that Gold Roger, his former captain, had once said.

Chapter 603 − Gol D. Roger

Much later in the series, it was revealed that Gold Roger, the man who would become the pirate king, had owned that hat.

Chapter 81 − Nami

She is the member of Luffy's crew that he more often gives it over to for save keeping.

Chapter 114 − Robin
Not mentioned on the list, but as explained by OP, Robin had taken Luffy's hat from him during their first encounter.

Chapter 314 − Usopp

Usopp briefly wore the straw hat during the Davy Back Fight against the Foxy Pirates.

Chapter 515 − Sweet Pea

Luffy was in a panic when he couldn't find his hat, but it saw one of the women in the crown watching him wearing hit.

In addition to the existing answer, in chapter 912, Tama from Wano also wore it, making her the 8th person who has worn the straw hat.

Can an Uchiha master Sage Mode?
If a child whose father is Uchiha and mother is Senju is born, will this child awaken the Rinnegan?
Will they be able to use Sage Mode because Senju have strong chakra to harness Sage Mode?

Is your question about sage mode or activation of rinnegan?

Please edit your question. The question title is asking something totally different from what the body is asking. Related to title question: http://anime.stackexchange.com/questions/20851/why-did-the-uchihas-never-try-to-learn-sage-mode Related to question in body: http://anime.stackexchange.com/questions/20464/does-the-uchihasenju-dna-ratio-matter-in-awakening-the-rinnegan

This is 2 questions wrapped into 1.

The uchiha and Senju are not what is required for awakening the rinnegan what awakens the rinnegan in the situation your speaking of is the chakra of indra and ashura Wich happens to be the Senju and uchiha in the case of Madara and Hashirama but this is not always the case in the way that Naruto an Uzumaki was the iteration from his generation of ashura what makes a rinnegan is the mixing of the two chakras not the two respective clans.

Well.. In order to awaken the Rinnegan, you need to have Ashura's and Indra's chakra. Having Uchiha and Senju DNA won't necessarily activate the Rinnegan unless those Uchiha and Senju are reincarnated Ashura and Indra.

The problem with an Uchiha learning Senin mode is that for you to learn that you need a large amount of chakra reserves. Something that the Uchihas tend to have a problem with.
You can see a lot of Itachi's early fights, Kisame mentions that Itachi cannot use his eyes for a large amount of time as it puts a large burden on his limited chakra reserves.
Also you need an immense amount of chakra control as to not let the nature energy turn you into a frog. Even Jiraiya, one of the legendary three, could not completely control the nature energy.
He admitted that he could never use his sennin powers without acquiring some frog features.
Naruto on the other hand, with his Uzumaki heritage, a clan that has worn at least twice the title of Nine Tails' jinchuuriki, and the fact that he had a truly immense amount of chakra in him from birth, made him able to control large amounts of chakra unlike any of the other sennin users.

I believe if a child is born from uchiha father and senju mother, and if that child awakens his sharingan and pushes through physical training(enhance his body strength), then ultimately they WILL awaken the rinnegan()under the proper circumstances -> situations that call to their emotions. The re-incarnation of indra and ashura has little to do with awakening a rinnegan as Indra himself did not awaken the rinnegan even though he was the first son of hagoromo. Madara(Uchiha) awakened his rinnegan only bc he had access to Hashirama DNA(Senju). Same as that uchiha/senju child we talking about here.

For rinnegan you'll basically need the Chakras of the Reincarnated Ashura and Indra's.
Not all Uchiha have the reincarnated Indra's Chakra similarity not all Senju's have Ashura's chakra.
This also applies for other clans.

Indra and Ashura are the two sons of Hagoromo (sage of six paths) who wielded the rinnegan. As the two sons of Hagoromo were born they each had a half of his chakra. With one half of the chakra they were very strong but they could not awaken the rinnegan on their own, they needed both halves of the chakra to do so. They could do this by transplanting one another's flesh, as demonstrated by Madara Uchiha (Indra's incarnate), thus combining their chakra to make up Hagoromo's chakra, or they could just receive chakra directly from Hagoromo himself as demonstrated by Sasuke Uchiha (Indra's second incarnate), but it is unknown to why Naruto (Ashura's second incarnate) did not receive the rinnegan, (probably because Sasuke already had it or because he already had his own dojutsu, the sage mode eyes).
I mean... If the Uchiha knew it was this easy, they would've seduced some Senju ladies like Tsuna and had rinnegan wielding babies a long time ago, LOL.

What was the history of the Tailed Beasts (Bijuu) before the formation of the Hidden Villages?
The founding of the Hidden Villages only goes back about 100 years. The same goes for the sealing of the Tailed Beasts. So is there any back history on them? Did they go on rampage a lot? Did they just ignore everything and it were the shinobi that discovered how to seal the beasts into themselves, to use as a tool of war? Or was it something else?

After the death of Hagaromo Ōtsutsuki, the Tailed Beasts went their own way. Kurama's belief, that the tails was a measure of strength, apparently paved way for the beasts to part ways.
The humans regarded the Tailed Beasts as monsters and sources of immense power. They did not care about the live essence the Beasts had.
To gain advantage during times of war, the humans tried to exploit the Beasts' powers. They only thought of the Bijuu as weapons of mass destruction. This in turn, angered the Bijuu and brought forth the hatred towards mankind.
From Tailed Beasts article:

Over the centuries, humanity failed to recognise the tailed beasts as sapient individuals, instead seeing them only as monsters, demons, or mindless beasts worthy of fear and disdain. Because of their immense power, the tailed beasts were sought out by humans to be used as weapons in times of war. The beasts resented this treatment and came to hate humans, at times willingly becoming the monsters they were viewed as.

So, they were trying to lead peaceful lives away from mankind before the formation of Hidden Villages. But due to the constant provoking of the humans, they decided to fend them off by becoming what the humans thought they were.

How was Kakashi Hatake able to survive and become the next Hokage after losing his Sharingan?
I hardly read the manga. I watch the anime series, Naruto: Shippuden. In episode 424, Kakashi's Sharingan (previously Obito's Sharingan) is stolen by Madara. Then in episode 425, Naruto uses his new power and give Kakashi's old eye (as far I know and from my view, it is a normal eye).
Kakashi is the Copy Ninja. So how could Kakashi survive in the ninja world and become the next Hokage (I watched The Last: Naruto the Movie) with normal eyes? I'm curious because Kakashi's nickname was given because he used his Sharingan for copying others' jutsu. That was his technique. As I can remember in Naruto series, someone described Kakashi and told that the only jutsu he mastered by himself was the Chidori.

Very soon in anime,

Obito will say that his gift for Kakashi was not full and will give him both Sharingans. He will manage to use Susanoo and save Naruto, Sasuke and Sakura from Kaguya's attack. I don't know why, but after war he has normal eyes, maybe he can deactivate Sharingan.

UPD.
I've read that chapter again and understood why he has normal eyes.

Obito says that his present may expire but it's not completely useless.

OMG, its a disaster for an anime-only user. At least add the spoiler tags !

I see the answer is lay future in the anime :) thanks very much :) @Mihai Svet

@KaguyaOtsutsuki, why would an anime-only user open this question?

@Kira-TheGod Interest would drive him to open this question. Why do you think spoiler tags exist in the site?

This answer would need an update, as the answer doesn't exactly reply to the question. It just readdresses the point that Kakashi doesnt have a sharingan after the Ninja war. Also, I am concerned about the fact that images from mangapanda are hosted here. I believe it is against the rules of the forum.

A sword is only as sharp as the one who wields it. The sharingan was nothing but a ninja tool that Kakashi used. And he was good at it considering the fact that he was not a true Uchiha.
However, the tools a ninja uses is not the only criteria that would be considered while appointing him to a post of a kage. His diplomatic skills, his relation with the other villages, his services to the nation are some of the other (among a larger list) that needs to be considered.
In all these aspects, Kakashi has excelled. There can be no doubt on the fact that Kakashi was capable of fighting with and without the sharingan. His skills in strategy were at par with the best of the best. He had fair diplomatic skills, which we can assume from the fact that he had already been appointed for the post of hokage earlier (right after Danzo dies). He was a person of calm demeanor and not pragmatic. He weighed his options before making a decision and could think calmly in the face of adversity. All these does make him a strong contender for the position of Kage.
Tsunade was not only appointed as the hokage because she was a great medical ninja, but also because of her services in the endorsing the idea of the 4 man ninja team with a medic ninja included in each team.
Also, the sharingan that Kakashi had only allowed him to read the movements of his opponents in a precise manner. His ability to copy the jutsu was aided by the sharingan, but in the end he had to commit it to memory so that he could use it later on. Also he must have had excellent chakra control to read the hand signs of a jutsu once and copy it immediately. Also, he himself mentions while aiding naruto create his rasen shuriken, that he could use chakra of elements other than thunder. We have seen him use water style, earth style and fire style. So, his strength is not solely because of the sharingan. Like a tool, the sharingan helped his cause.

Kakashi did not have his sharingan anymore. However, Kakashi did still have all the abilities he was shown copying and the last ability he copied in the naruto series is water dragon jutsu which was in the first series and it made it that far without copying another jutsu. I bet there are thousands of more jutsu that Kakashi has than the amount he's shown.

Why does Zoro's "1080 Pound Phoenix" use the term "pound" instead of "kilogram"?
I was recently reading One Piece (specifically chapter 754), and I noticed that Zoro used the attack "1080 Pound Phoenix."

After I read through this chapter, I was rewatching the anime with my sisters (episode 66 in this instance), and we were in the Baroque Works arc and I noticed that Miss Valentine declared her attacks as "10,000 Kilogram Press."

I'm pretty sure that Japan does not use the imperial form of measurement, so was the translation of "1080 Pound Phoenix" incorrect?

It's not a mistranslation; the original uses the furigana ポンド (pondo, "pound"). Ref

@キルア Is it just an artistic choice then? To have the differentiation between "Pound Phoenix" and "Kilogram Press" that is.

Since the Pound Phoenix title is a pun on a couple things (as noted in the reference I gave), I would guess that it is an artistic choice, yes. Since it is not only a pun but also a reference to a type of gun (the force of which is measured by pound), it makes sense for them to not alter it. However, it seems that Kilogram Press is just a standard term that follows Japanese conventions.

@キルア I saw that article but I didn't notice the part about the naming. Thank you very much for pointing it out to me.

As was pointed out to me by キルア, the reason Zoro uses "pound" in "1080 Pound Phoenix" is purely an artistic choice. The original Japanese uses the furigana ポンド (pondo, "pound") reference.
Also, as the wiki points out, the choice to use pound incorporates a sort of pun.

The attack's name is actually a very heavy pun — it is written out as "Phoenix of the 108 Earthly Desires" in the manga with a skewed reading attached that makes it "108 Pound Hō" when read out. Ho means both "cannon" (砲 Hō?) and "phoenix" (鳳 Hō?), however the attached kanji is for "phoenix", making that the literal translation and the "cannon" reading a pun on that, both of which are correct. The "pound" part is a skewed reading of the kanji for "earthly desires" (煩悩 Bonnō?), and it is referring to the caliber of a cannon (a 108 Caliber Cannon would fire a 108 Pound Ball).

Thank you again to キルア for pointing this out to me.

Can Dragon Slayers teach Dragon Slayer Magic?
Can Dragon Slayers teach other people Dragon Slayer Magic just like how the Dragons taught them?

I suppose they can, but there is no proof of this as we have not seen any dragon slayer teach anyone dragon slaying magic.

@Alagaros or at least people with dragon slayer magic. Come to think of it, what would qualify as dragon slayer magic? Would it be like just the fashion in which Natsu handles fire or would it also count the other various abilities he gets from being taught by Igneel (i.e. eating fire)

@Cyberson The same question goes for a dragon. What qualifies as a dragon? Is a dragonslayer in his dragon form (aka Acnologia) able to teach Dragon Slayer Magic or does he not count as a real dragon?

According to the Wiki, Dragon Slayer Magic is a form of lost magic. We know that Ultear was able to learn a form of lost magic called "Arc of Time" from Hades.
However, we know that there are currently two ways you can obtain Dragon Slayer Magic:

Learn it from an actual Dragon.
Implement a Dragon Lacrima into your body.

Therefore, I would say yes, this might be a third way to teach someone Dragon Slayer Magic.

lol, so in the comment you say it is unlikely, yet here you say it is possible? Btw the same question as I asked above, what is an actual Dragon? Is a dragonslayer in his dragon form an actual dragon or still just a dragon slayer? What I'm trying to ask is, would Acnologia be able to teach someone DS magic?

@PeterRaeves I posted my answer after doing some research, on the Wiki he is considered a dragon slayer. Since he uses dragon slayer magic to get into his Dragon form he still is considered a dragon slayer.

How does Edo Tensei Madara get back his Rinnegan?
Madara gave his Rinnegan to Nagato. But after Kabuto brings him back using Edo Tensei, he still has the Rinnegan. How is this possible?

When Edo Tensei Madara appeared on the battlefield, Kabuto (in Mū's body) tells that he modified Madara's body to reflect his prime state. Which includes physical prime from his youth, wisdom and memory till his age of death, Hashirama implants, etc. These are the in-story details that support the Rinnegan in ET Madara

Same happen to Itachi , related question Nagato's Eye in Edo tensei Mode

Reincarnation technique gives the user all their abilities, every single one they ever had. (thanks to 2nd Hokage and damn Orochimaru!)

Narutopedia:

A reincarnated individual will have all the abilities they had during their life, including kekkei genkai and kekkei tōta. They are psychically restored as they were at the time of their death, including any physical handicaps they may have possessed, such as Nagato's damaged legs.

Since Madara had the Rinnegan when he died, he is resurrected with it again (with the help of Kabuto's modifications, if you remember).
However, the Edo Tensei Rinnegans are fake. Although Edo Tensei Madara can use them to absorb ninjutsu, he can't use it to summon the Gedo Mazo, or use Limbo. It's kinda the same with Nagato's Rinnegan or Itachi's Mangekyo Sharingan.
For further proof, when Madara was revived in flesh through Rinne Rebirth, he lost his fake Rinnegan.

Just a small correction, he didn't revive with the Rinnegan because of Kabuto's modifications. He would have been Edo Tensei revived with it regardless because he had it when he died. Kabuto's "modifications" revived Madara with his youthful, most powerful body instead of the old and frail one he died in.

Actually Madara didn't give Nagato the Rinnegan,he only awakened it in him,and as he was an Uzumaki (which are distant relatives of Senju),he was able to control it.Madara got the Rinnegan by merging Hashirama's cells with his heart,awakening his Rinnegan very late in his life,after which he shortly died.That is why,when he was resurrected he had the Rinnegan.

Do you have any reference for that? I thought madara gave the rinnegan to Nagato so that he could use it to bring madara back to life.

Madara flat out said he gave his rinnegan to "someone" while talking to obito, and he only had one regular sharingan eye. Before he did that, he summoned the Gedo mazo and extended his life until he chose to die, leaving everything to obito.

Yeah, but Nagato has two rinegans not only one, and he awakened in chieldhood, so is not Madara's rinegan

@Rezende Nagato has only one rinnegan

Nagato had two Rinnegan eyes, which was transplanted by Madara when Nagato was just a child. The Rinnegan was indeed Madara's.

Yes, thats it, Two by Madara

How did the Kaguya clan come into existence?
How was the Kaguya clan related to Kaguya and when was the clan formed?

The when and how the clan came to be are fairly unclear through out the series. But we can make a guess as to when very roughly.
According to this timeline, Gamamaru was born in 984 BK (before nine tails attack). Which was said to be the same generation as Hagoromo, the first son of Kaguya Ōtsutsuki. Meaning that the creation would be in one of the years to follow
The clan was named after the first known user of the Tomogoroshi no haikotsu. As their power, the Shikotsumayaku was a derivative power of it.
This derivative power was obtained through descendants of Kaguya Ōtsutsuki, indirectly making her the creator of the Kaguya clan.

How was the Kaguya clan related to Kaguya?
By Kaguya clan, I'm guessing that you're referring to the one mentioned in this link. Well, they were descendents of Kaguya, which is why some of them gain the rare kekkei genkai "Shikotsumyaku", which gives you some of Kaguya's "bone powers". If you remember Kimimaro manipulating his bones when fighting against Naruto, you know what I mean.
When was the clan formed?
Well, we're not sure, since it wasn't mentioned in the anime or manga. But we do know that they were descendants of Kaguya, so maybe they existed a long time ago, maybe even not far after Ashura and Indra's death (unless they came from Hamura's lineage). We also know that they were extinct after their attack against Kirigakure and Kimiaro's terminal illness, but that's about it.

We know that neither Hagoromo nor Indra or Ashura used the bone Kekkei Genkai, so it might have gone to Hamura's children. Hagoromo's eyes went to Indra and his chakra went to Ashura. Hamura's eyes went to the progenitor of the Hyuuga clan. Maybe Hamura's chakra manifested in the Kaguya-clan as bone-manipulation. This hypothesis is bolstered by how Hamura was closer to Kaguya than Hagoromo, so maybe he gave one of his children the name.

Übel Blatt Manga: What was the purposes of naming the 4 lances of betrayal?
Potential Spoilers
What was the purpose of the seven heroes to name the 4 people as betrayers of their quest, even though

 They were the real heroes and completed it. I understand why they were killed. Why not just let the king know that they too died after completing the quest? Why was their name dragged through mud. We see a lot of negative consequences of this, for example Kfeer's family ostracized and his territory thrown in Civil War.

Why demean the memory of their friends instead of honoring their memories?

Every hero is praised and loved by people. But it's hard to have many heroes. Don't you think, that if there were 9 heroes, 4 dead of them would actually get even more attention and praise, than rest 5 survivors, since dead ones would be considered as martyrs?
I suppose, 5 betrayers named killed heroes as lances of betrayal, to get as much fame and praise as possible
I'm updating my answer after rereading several tomes.
In 5th tome, 6th chapter, when Glenn confesses to Ms. Gleaa, that 4 lances were not traitors at all, she asks him same question, as you did here. What Glenn answers:

We were young... Too blind and too consumed with ourselves to consider other options...

My memories of Ubel Blatt are very foggy (sadly).
I am certain it was to further increase their personal status and profits.
Not only did they fulfill the hardest of quests, they even saved the kingdom from the traitors.
And obviously they didn't think of the 4 as friends.
(If I find the time I will reread it :)

In Naruto Shippuden episode 467, how was a normal villager able to use jutsu?
There was a scene in Episode 467 of Naruto Shippuden, where Ashura taught ninjutsu to a villager.
But I have been led to understand that only descendants of Kaguya can use jutsu (because originally Kaguya was the origin of chakra).
How can they use jutsu if they're not descendants of Kaguya?

Shinpunden? or  Shippuden?

IN addition to the answers, It is also Filler, so it breaks a LOT of rules. Asura did not have the Sharingan according to Canon (or at least was never told/shown to have had it), as well, Hagoromo was never shown with anything besides the Rinnegan in canon. Quite a bit of story conflicts with what was said in the manga.

Yes you are right but :

Hagoromo travelled across the land, giving chakra to everyone in the
  world as well as spreading his ideals and religion

so it is possible that Ashura might have just shared his chakra just as his father Hagoromo did.
