Why did Funami Yui accuse Toshinou Kyouko of playing dirty?
In episode 4 minute 1:35 to 1:45 of the Third season of Yuru Yuri, Yui accused Toshinou of playing dirty after she won against Ayano. From what I understand, they are playing bomberman-like game. What is dirty from Toshinou blowing up Ayano?

The following anwer is made by assuming that they are playing on a Bomberman version similar to one of those which actually exist.
A proof that this may be similar to a known version of Bomberman is the bonus Ayano is trying to pick up, which looks really similar to Fire and  Full Fire  bonuses

Basic Bomberman knowledge
In the classic games Bomberman, there are a lot of power-ups.
One in particular, Kick, gives to the one who collected it the ability to kick away Bombs. This is the only ability that grants the power to move a bomb after it has been planted.
This may be used in 2 ways :

To eject the bomb that would threaten your life;
To push an enemy bomb or your bomb into the enemy's face.

What's more, it is important to know that bomb explose after a determined delay after it has been planted.

But what happend exactly?
Ayano did plant a bomb in order to destroy a wall and therefore is unable to move (if she does, she may be killed by her own bomb)

After the wall exploded, Ayano's first reflex was to leave this dead-end to pick-up a bonus.

Toshino may have anticipated that Ayano would have this behavior.
Toshino planted a bomb near to herself, managing to time it so it would explode just a little bit after Ayano's bomb. Then she pushed the bomb with the bonus we talked about earlier (we can be sure of this as long as the ability to move bombs is unique to this bonus) and killed Ayano.

Why is Yui reacting this way?
Bomberman is usually meant to be played around strategy, which means placing your bombs in order to force the enemy players' movements, and therefore block them.
As an example, placing a bomb on a line will force a player to go to the other end of this line. By playing on this kind of forcing, you can "place" enemies on a dead-end or a really close place where they are more vulnerable to bombs.
The natural reaction of an awared Bomberman player is to spend the less possible time in dead-ends. They are deadly because you cannot go through bombs unless you have the Bomb Pass bonus.
Here, Toshino is just waiting for enemies to destroy walls in order to kill them instead of placing bombs herself.
Therefore, this kind of trick can be seen as unfair or dirty because it is playing on a survival reflex and is not really the part of a global strategy.

What do you mean by "not really the part of a global strategy"?

I edited my answer to clarify my point

What is the "SNAFU" in My Teen Romantic Comedy SNAFU?
The Japanese title is Yahari Ore no Seishun Rabu Kome wa Machigatteiru with subtitle My Youth Romantic Comedy is Wrong as Expected. The subtitle already pretty much translate the Japanese title. So, what is the SNAFU in its English name? How did it get there?

Are you asking for a definition to the word? If so, your question can be considered off-topic. Similar to asking "what does "canon" mean?"

I don't know how did it get but the word SNAFU means Situation Normal: All F**ked/Fouled Up.

The subtitle is basically a literal translation of the Japanese title. The "snafu" part of the English title has no analogue in the Japanese title. I've only seen the first episode of Oregairu but it wouldn't surprise me if the English translators just tossed that in because they thought it sounded good, and there was no event in the series that "snafu" was supposed to refer to. This sort of thing used to be very common among English translators of anime, though it's thankfully become less and less common.

Here, the word for wrong - "machigatteiru" - is being changed into "snafu," which, according to the dictionary is "a badly confused or muddled situation"
When translating literally, we could just use "wrong" (as in the subtitle you mention). However, an important thing to note about anime is that translations are almost never exact. Whether it's just the dialogue, or the entire anime name, many things can be changed to suit a western audience.
For instance, consider the title "chuunibyou demo koi ga shitai" (Literally: Chuunibyou, but I want to do love) which in English is officially titled "Love, Chuunibyou, and Other Delusions." A much more marketable title.
Similarly, with Oregairu, the English licencing company likely decided that using a more "interesting" word like "snafu" would make the show more intriguing to western consumers, thus improving sales.

As a quick follow up that isn't exactly on topic - lots of things besides dialogue and show names can be changed to target a western audience (though I believe this is done a bit less these days). For instance: replacing onigiri with hamburgers, and even changing character names.

I suspect that whoever decided to use the "SNAFU" translation for the title was going for the original military acronym "Situation Normal, All Fucked Up", rather than the contemporary non-military meaning of "something that has gone wrong".
Why? Well, the title in Japanese is "yahari... machigatteru", which means "...wrong, as one would expect". If that isn't a borderline literal (if less vulgar) equivalent of "Situation Normal, All Fucked Up", I don't know what is.
(This is also, in my >opinion, a better translation choice than "...is wrong as expected", which is relatively unnatural and pretty obviously directly calqued from Japanese.)

I would imagine, with the title being along the lines of "My Teen Romantic Comedy is Wrong, As I Expected", that it could be for "Sonna Fuu Ni", which is "Couldn't Be This Way".
It's pronounced Soh-Na Fuu-ni, so Sxx-NA-FUx-xx.
Just a personal thought.

Interesting, but seems unlikely since the title is translated for English-speaker audiences. Pretty sure they wouldn't get this reference since the term SNAFU is more recognizable than an attempt at Japanese wordplay.

What are the differences of anime in 1990s and 2000s in terms of technology used?
What are the main differences between anime in the 90s and in 2000s in terms of technology used (like on twos, on threes, etc)?

I think this question might be a little too broad or opinion-based, but I'm really curious to know, so not voting to close it yet.

"on twos" vs. "on threes" is less a matter of technology and more a matter of budget. The obvious big change on the technology end of things is the move towards CG that began in the early 2000s, I guess. Maybe somebody can write a good answer about that.

Yea, I agree with senshin that there really is no difference in technology between "on twos" and "on threes". What are "on twos" and "on threes"?.

I would expect the technology to advance slowly and only maybe have the occasional jump here and there. But there is no reason why such a technological jump should occur exactly at the turn of the decade. Is there any reason why 90's vs 2000's?

This is a fairly tough question to answer, as most changes did not just apply to Anime, but to how movies, series and even advertisements as a whole, and the way they got made.
It is however an interesting time period you picked, considering the economic slump of the 90's, which they only started to recover from in 92

A slump in advertising revenue, dwindling birthrates, and the popularity of alternative forms of entertainment like video games and cell phones have led to sluggish prime time ratings and a decline in the number of anime since the peak in 2006... ...The Japanese anime industry is at a turning point. - Nippon, 2013

Rise of 3D animation and CGI
All though 3D animation was already existent around the 1940's. It had a 'said' breakout year in 1991. As more and more studios started to adapt the technology, we can slowly see it replace older, more Traditional Animation techniques throughout the 90's and during the beginning of the millenia.
Due to these changes, there where also significant advances in the field. Such as the 2000 breakthrough in capturing the reflectance field over the human face, being the final breakthrough to making digital look-a-likes of actors, Or the 2001 Motion capture, photorealism, and uncanny valley.
The later of which was applied on the 2001 Japanese-American Final Fantasy: The Spirits Within, which was the first photorealistic computer-animated feature film and remains the most expensive video game-inspired film of all time.
Besides obtaining a first in Photorealistic computer animation, Japan can also claim the title for being the first in using cel-shaded animation, with Appleseed.

"innovative use of out-of-the-box animation software to create Hollywood-style effects at a tiny fraction of Hollywood budgets."
Mark Schilling, The Japanese times & Toshio Suzuki president Studio Ghibli

Death of traditional animation
Traditional Animation, also known as hand drawn animations, or cel animation.
During the 90's as more and more studios started to adapt digitalized animation, the art of traditional animation started to slowly die out. Some studios dived straight into the deep, leaving traditional animation behind almost immediately, while others started by mixing the digital and traditional ways.
This would continue till FujiFilm, one of the major cel production companies, announced they would stop cel production, leading to a industry panic, hastening the switch to digital processes
Around the early 2000s most studios left behind traditional animation for the more modern, digital animation.
There was however 1 exception to this, Sazae-san. But even though it was the sole survivor, they also gave in to the modern age in 2013. When even they said goodbye to cel animation.

begin 90's turning point facial animation
Historically speaking, the first SIGGRAPH tutorials on State of the art in Facial Animation in 1989 and 1990 proved to be a turning point in the field by bringing together and consolidating multiple research elements and sparked interest among a number of researchers
https://en.wikipedia.org/wiki/Computer_animation

3D animation in the 1940s?  Before the first computer?  I'm guessing that's a typo since you later refer to the 1990s...

@YetAnotherRandomUser 1940's is not a typo. I am not sure what you are reffering to with first computer, but there have been computers before 1940. A good sample would be the Z1 from 1936 and 1938

What does it mean that Gintoki and his friends are "Yorozuya"?
In the Gintama series they mention a lot of times about Gintoki and his friends are "Yorozuya". What does this mean?

Without knowing anything about Gintama, yorozuya (万屋) means Jack of all trades.

Like these ppl make the brand/name of Yorozuya. Like members in a band that make the band what it is.

Gintama is the name of the series. The person with naturally permed white hair is Sakata Gintoki.

Yorozuya means Jack of All Trades. Other subs translated Yorozuya into Odd Jobs.
They are called so because they would do any job at all for money. Any jobs ranging from chasing after run away cats to saving the world.

How can Rock Lee stand on water?
According to what I have seen, Rock lee isn't able to use ninjutsu nor genjutsu. However, it was shown that he can walk on water. Isn't walking on water a part of chakra control which he isn't able to perform? If he can control chakra then why not perform ninjutsu (doesn't need to be good at it, but at-least perform it.)
Also I am unable to understand how can he open the inner gates of chakra if chakra control is a problem for him?

If im not mistaking, He's just cant change the shapes of chakra (forgot what it's called) but he's still can control his charka to open the 8 gates, for walking on water it's doesn't need to change the shapes, just control the chakra around his foot

Chakra Control
There are three things about Chakra Control.

Power Manipulation
This is my own term. It refers to how much Chakra you mold upon performing a jutsu. Quoting Wikia,

In order to have good chakra control, a ninja should only mould as much chakra as they need to perform a given ability. If they mould more chakra than is needed, the excess chakra is wasted and they will tire out faster from its loss. If they don't mould enough chakra, a technique will not be performed effectively, if at all, likely creating problems in a combat situation.

Shape Manipulation

Shape transformation deals with controlling the form, movement, and potency of chakra.

Nature Manipulation

Nature transformation deals with changing the physical properties of chakra into an element. There is also the nature transformation of Yin and Yang, which deals with changing the ratio of spiritual and physical energies within chakra.

Rock Lee
What Rock Lee was incapable of is the last two, Shape Manipulation and Nature Manipulation. Most Ninjutsu requires at least one of these two. For example, Katon: Goukakyu no Jutsu (Fire Style: Fireball Jutsu) requires both shape manipulation (to make it into ball) and nature manipulation to give fire element to the jutsu. Rasengan requires shape manipulation to make it into ball shape, although in a whole different level than Goukakyu no Jutsu. Chidori requires nature manipulation to add lightning element to the jutsu.
It has been consistently shown that Rock Lee was unable to perform the last two in that he was never shown to use any jutsu that requires them. He, however, was shown to be able to perform Power Manipulation. This is evident in his use of the 8 Gates which requires him to flow chakra to various spots in his body.
Standing on water requires Power Manipulation, that is, creating enough chakra to cover his feet palms to keep him afloat. It doesn't require shape nor nature manipulation, thus explains how Rock Lee can stand on water.

Excellent answer. To add to this, the Iron Fist style Lee and Guy uses are the same as that of Sakura. They can release Chakra from the palms at the moment of impact to increase the destructive force. The physical moves are not only muscle strength but Chakra too, and hence Taijutsu utilizes Chakra as well.

To my knowledge there are varying levels of Chakra control that the ninja are able to use. Simple controls, like being able to focus chakra in on area, such as the feet in order to stand on top of water, are low level and even Rock Lee would have access to this, though he may have had to train a bit harder to get there.
Rock Lee is only unable to perform the more difficult chakra transformations that would allow him to use various skills and abilities, which is why he focuses on physical combat.

It is my understanding that Rock Lee is not incapable of channeling chakra. he simply has no natural talent at either ninjutsu or genjutsu. Ninjutsu was defined in the show as a combination of Shape manipulation and Nature manipulation.

 hence why the Rasengan is considered an incomplete technique.

A genjutsu is created when a ninja controls the chakra flow of a target's cerebral nervous system, thereby affecting their five senses. In other words the caster uses their chakra to directly influence the mind of the target, effectively forcing them to hallucinate.
As water-walking is not a technique per se, but instead just a manipulation of chakra, Lee can do that.
If you are looking for the OFFICIAL answer however, I advise giving up now. No clear reason was given.

"Ninjutsu was defined in the show as a combination of Shape manipulation and Nature manipulation." This is not really true, the rasengan is ninjutsu but is shape manipulation only.

The Rasengan was referred to as incomlete due to the fact that it lacks nature manipulation by Kakashi while Naruto was learning how to use the wind element in Naruto: Shippuden.

How can Mjolnir Hammer joins the Far Eastern Magic Nap Society of Summer?
By the time the club was established, Mjolnir Hammer, Dekomori Sanae, was a junior high student. How can she join the club? Was it because her junior high and the senior high that Tyrant Eye, Takanashi Rikka, attends is an escalator school? Is it common for student of an escalator school to attend club of the higher school in Japan?
If we don't count Dekomori as an official member of the club, then the club would have only 4 members (Dark Flame Master, Tyrant Eye, Mori Summer, Tsuyuri Kumin) which is one less than the minimum for a club.
Note: I'm not sure that the school is an escalator school. The uniform is similar and I think Yuuta once said to Dekomori, "Oh, you attend our junior high, huh?" which suggest that the school is an escalator school, but I'm not sure if I remember it correctly.

It always seemed more informal than that; nobody would question her presence in the school because of its status as an escalator school, yet she wasn't officially part of the club

But the teacher who they asked to be their club advisor didn't object to Dekomori joining at all. She did object when Rikka wanted to enter Chimaera as a member since Chimaera is a cat. Why wouldn't she object to Dekomori as well?

Based on Wikipedia,
The school is escalator school in anime version only.
Dekomori is anime only character that problem is not exist LN version..
Club system in escalator school is depends on the school.
Some schools have totally separate clubs.
Some schools have shared one club between junior high and high.
Some other school have joint club for cultural club and separate club for sports related club.
I'll try to add some reference about clubs in escalator school. (sorry links are in Japanese.)

From answer of this question(Does escalator school have shared club?), most school share the club between junior high and high. (The answer said they also have shared "seitokai" Student council)
Son of this blog author "graduated" baseball club in junior high, and joined high school club next day. so in this case clubs are separated.
This article said one of good thing of escalator school is share the club.

I think you're on to something here. More reference on escalator scholl clubs please?

Tried to find but I can found article in Japanese only. sorry.

Where can I watch Seiyuu shows?
By Seiyuu shows I mean things like Hanazawa Kana's Hanazawa Kana Hitori de Dekiru kana, Matsuoka Yoshitsugu's Matsuoka Restaurant.
Is there anywhere where one can watch them completely with consistent quality? I can find them in YouTube but it was the one uploaded by some random guy on the internet. The quality also varies greatly, like some only have voice, some with only low res video, and it also miss some chapters (i.e incomplete).
Note 1: limit answer to legal sources.
Note 2: not limited to the said shows. They are just examples.

Important question: since you're looking for legal, high-quality source, is Japanese site okay?

@AkiTanaka of course

i assume if it doesn't matter if it has english subs or not?

@Memor-X yes. Preferably with one since shows like Uchida Maaya's one where her brother Yuuma came as guest can be hard to follow due to them talking very fast. But it's okay even without subs.

Hanazawa Kana's Hanazawa Kana Hitori de Dekiru kana:
You can listen to this radio program on Thursday, 23:00-23:30 Japan time, by visiting the following URL: https://www.uniqueradio.jp/form/form5.php.
This channel is legal under Japanese law.
I don't know if it's accessible from outside Japan.
You will be asked in Japanese where you live, your occupation, and your address. There is no option to choose an address outside of Japan, but you may choose Tokyo.

The Onsen (Japanese) is another well-known channel that offers voice actor's programs, but I don't know if it's accessible from outside of Japan.
At least the following YouTube channels are legal under Japanese domestic law. As these are YouTube channels, they can be accessed from outside of Japan.
These are provided by the holder of the official content.

Dengeki Bunko Channel
TrySail official YouTube channel
Second Shot Channel
Phonon Channel
YOUDEAL LIVE Channel
GA Bunko Channel
GAGAGAch!!!
warnerbrosanime
ANIPLEX
Hi★Channel
Bushiload
NBC Universal Anime/Music
KING AMUSEMENT CREATIVE
Anime Channel by FuRyu

For some content it seems to be possible to use Youtube's automatic subtitle generation.
Some of above content providers are American companies, but the contents are related to Japanimation.
Some channels seem to have special sub-channels. For example, the NBC Universal's channel, has the Gochiusa's channel as a sub-channel.　The operation of such a subchannel may be limited to when the program they want to promote (like Gochiusa) are on the air.

From my experience, seiyuu shows/events falls into a few categories

Shows, events, Internet radio related to anime.
When it doesn't make economic sense to sell the event on a separate BD/DVD, these are included in the original BD/DVD of the anime. WORKING!! series, Oregairu series, High School DxD series, Tengen Toppa Gurren Lagann are a few examples of this category. Unfortunately, most of these contents don't make it to any of the international release, so most of the time, the only option to view them legally is to import the BD/DVD from Japan.
There are some cases, such as Matsuoka Yoshitsugu's Matsuoka Restaurant series, or Tesagure Bukatsumono Bangaihen, where it's marketable on its own and comes in a separate BD/DVD. These are even more unlikely to be licensed outside Japan, so the only legal option is to import BD/DVD from Japan.  K-ON! Live Events are pretty much among the few exceptions that enjoy Western release.
Internet radio related to the series are occasionally bundled in the limited edition of original BD/DVD. Other time, they are sold separately. I don't know of any Internet radio CD ever localized to be sold outside Japan.
Shows or events (live) streamed on NicoNico
These days, many anime events are live streamed on NicoNico. However, most of them are geo-locked to Japan, so there is little chance that you can watch anything you want outside of Japan. If you are in Japan, it's possible to pay for the premium service to use Time Slip feature to watch past live events.
Shows or events streamed on YouTube
I only know of GA Channel by GA Bunko which fits into this category, and the show is more or less an advertisement of new light novels and some interaction with the seiyuu. In this case, the shows are free to stream from YouTube.

Who was Levi's host?
Spoiler alert! Do no proceed unless you are up to date with the manga or you don't mind being spoiled.
In Chapter 112 of Shingeki no Kyojin, according to Eren, the Ackerman are able to unleash their power when their host are in danger and they will often have headaches as their inner self fights against the instinct of the Ackerman blood.
He then told Mikasa that her tagging along wherever Eren goes is just from her Ackerman blood as Eren is her host.
Levi is also an Ackerman and as seen multiple times, he is capable of nearly inhumane feats such as slaughtering a horde of Titans all by himself. My questions is, who was Levi's host? Was it Erwin? If so, do we have proofs that it was him?

For Levi, that person is Erwin. He has acknowledged Erwin as an existence who he looks up to. It’s part of the Ackerman bloodline, or an instinctive part of them, you could say.
  source: Hajime Isayama, book of answers

I think the answer is pretty obviously Erwin Smith. Erwin was one of the only people Levi respected unconditionally, and from whom obeyed every command showing Levi's immense trust in Erwin. Additionally, right before the Return to Shiganshina Levi threatened to break Erwin's legs to make sure he couldn't go into battle to make sure Erwin wouldn't die. So yeah, it seems that Erwin was Levi's "host."
That being said, Levi's connection to Erwin disproves Eren's belief that the Ackerman's (Mikasa) are slaves/cattle with no free will. Because despite the fact that Erwin was seemingly "Levi's" host, when having to choose between Armin and Erwin to save Levi still chose Armin meaning that Ackerman's despite imprinting onto someone like Uri for Kenny, Erwin for Levi, and Eren for Mikasa are still able to make choices of their own free-will that could endanger or even kill their "host" like Levi did of Erwin

Nicely written answer. I think this answer needs some kind of reference from any of the wiki to be accepted by the user. Please link if you have any.

Or that letting him die was Erwin's wish thus Levi wasn't able to disobey that.

There is no proof that this connection Ackerman-host does actually exist. Furthermore in the latest (118) chapter:

 Armin speculates that Eren made that entire thing up in order to convince everyone that he is siding with Zeke.

SPOILERS!!

Is Tale of Fairy Ice Trail Considered Canon?
Well, is that manga considered canon? I heard that Hiro Mashima praised it as being very good, but does he also accepts it as canon?
Edit: The Key of the Starry Sky arc are not in the manga, yet Mashima-sensei considered it as canon. So, considering this fact, does Hiro Mashima consider this series as a canon as well?

I don't think so, I've searched Fairy Tail Wiki and found this:

Tale of Fairy Tail: Ice Trail (氷の軌跡, アイストレイル, Aisu Toreiru) is a Japanese manga series by Yusuke Shirato and a spin-off of Hiro Mashima's manga series Fairy Tail.

If it's a spin-off I don't think it's canon

that it's a spin-off doesn't mean it's not canon, there have been a lot of spin-offs of series which are canon. "In media, a spin-off is a radio program, television program, video game, film, or any narrative work, derived from one or more already existing works, that focuses, in particular, in more detail on one aspect of that original work (e.g. a particular topic, character, or event). A spin-off may be called a sidequel when it exists in the same chronological frame of time as its predecessor work"

Indeed, Fairy Tail Zero is an example of a spin-off which is definitely canon. So the term "spin-off" does not imply non-canon.

Must you write the full name of a person in the death note to kill them?
So let's say I wanted to kill, for example, David Connor with the death note. But his full name would be David Winston Connor. Must I write his full name, or is David Connor enough?

David Connnor should be enough, in How to Use I it says

This note will not take effect unless the writer has the person's face in their mind when writing his/her name. Therefore, people sharing the same name will not be affected.

That alone should be enough. if, by some genetic miracle, 2 identical people with the same name existed then adding the person's full name (ie. Troy Delu vi La'Flash) may then allow the Death Note tell the difference between the 2.
IF, and this is a huge if, that 2 identical people with identical full names existed then it's quite possible they will be immune unless the cause of death was

David Winston Connor dies from a heart attack in 40 seconds after writing his own name in the death note

but try and get someone to do that, also the odds of 2 people like that being born is insanely huge.
NOTE: To clarify a point raised by trlkly, How to Use: LIII talks about writing one's name across multiple pages, Point 1 says it wont work but Point 2 says that the front and back are still one page and talks about writing the surname on the front and given name in the back. this seems to imply that by name it would refer to the given and surname.

the odds of 2 people like that being born is insanely huge

True. But then face alteration and 'Plastic surgery' are not out of bounds!

If they would be immune, all people in a criminal organization should officially change their names to the same name and do plastic surgery for the same face. They would rule Light's new world.

This would imply you could just write someone's first name and have it work, as long as you knew their face. I mean, there are multiple people with the name David, but I'm picturing a specific David. That would seem to work by what you say.

@GauravAgarwal i don't think even with Plastic surgery you could get a 100% replication, and even then it would still have to be a stroke of luck to have the exact same name as the person you're trying to become, not to mention the time and money it'll take leaving a window of opportunity.

@PeterRaeves i feel so sorry for an organization who names everyone "David Winston Connor" and forces them to all look identical, be hell when it comes to giving payment, also imagine the orders! "David, can you take David and David and pick up David's team before the Police bust them, we don't need them revealing David's safe house, otherwise she'll be pissed off at us for letting it happen" (yes, i'm plying that they would make a woman into David)

@trlkly How to Use: LIII, Point 2 But the front and back of a page is considered as one page. For example, the Death Note will still take effect if you write the victim's surname on the front page and given name on the back. i think it implies that by "name" it means first and surname. i'll be sure to add it in my answer just to clarify

I think David Connor should be enough as the death note requires you to know the name of the person AND know the face of the person.
So as long as you have the face in your head, the middle name is not important.

Can Kisame breathe under water?
Can Kisame breathe under water? He's still a shark. He has lungs but those things on his face are branchiae, right?

Kisame having gills on parts of his body means he is likely to be able to

He has small, round, white eyes, 3 sets of curved facial markings under his eyes, gills on his shoulders

However I don't believe Kisame was ever shown being able to inherently breathe underwater (somebody correct me if I am wrong), a majority of fans are speculating that he is able to due this factor and his overall shark-like appearance.
However, later on in the Shippuden series, Kisame is shown being able to breathe underwater when fusing himself with his sword

When fused with Samehada, he gains the ability to breathe underwater using gills which form on his neck

"Yes, but only when he fused with Samehada" was going to be my answer.  You're spot on here as well.  Be sure to cite your quotes a bit more concisely.

in the anime when he steals back chakra from Bee after exiting Samehada, its shown that bubbles escape the gills on his shoulders, so they might be functional.

How did Nagato gain his Rinnegan?
How was it exactly that Nagato came upon his Rinnegan?
Madara states that it was his, and that he gave it to him: how did he do that? Did he transplant it into Nagato, or did he transfer it otherwise?
Note: I do not recall whether this was explained in the manga or not.

Well,

 Black Zetsu, which is the embodiment of Madara's willpower and thought (Yin), stated that he had indeed transplanted these eyes into him when he was a boy. When or how isn't stated, one can only speculate that Madara used White Zetsu or some other Zetsu for it.

In Chapter 606,

 In Obito's flashback, Madara mentions that he did indeed transplant it into Nagato without him (Nagato) realising it. How exactly he did it is not explained, though it is likely he used a Gedo Mazo/Senju cells based technique similar to the one he used to "repair" Obito's body (without Obito realising it as well).

Like you said, it certainly was not mentioned.

 The best guess is that he used Zetsu to do it, since he was chained
 to the Gedo Mazo.

 Apparently he knew he could use it in the distant future to revive
 himself again.

"I want to forget the little nuts"
In the Ending animation sequence of Jintai, the song Yume no Naka no Watashi no Yume
(My Dream Within a Dream) plays with the following lyrics in romaji:

Wasuretai tte kimochi
  Sore mo uso ja nai kokoro

On Anime Lyrics it is translated so:

The feeling of wanting to forget
  It, too, is an emotion that is not a lie

But in the subs I have, it is translated like this:

What is it?
  There you sit on my lap, little squirrel
  The chestnut is like your flag, you child of the forest, seeking courage
When the sounds of March are all around, even the humans will know
Day in, day out, I sow the seeds for the future
  Eventually they bloom to flowers, and all feast on what it brought to fruit
  My dream fulfills that of the others at the same time
  Isn't it nice to make your wishes then?
I want to forget the little nuts
  That's what I really feel like
What's wrong today?
  You wave your chestnut like a flag, little squirrel
  Soon you will run to the forest again, your refuge
  What's wrong today?
  Here you sit on my lap
  Why don't you rest?

The animation sequence itself contains many objects that come directly from the story. Most of them I recognized, but where do these little nuts come from in the subtitle translation? Was it a mistranslation or some subtle reference to the events of the story? I wonder if the differences are because of some double-meaning words or some hidden context that one of the translators (or both) didn't get.

While I obviously can't be sure, it seems likely that the translator for the subtitles  misheard 気持ち kimochi "feelings" as 木の実 kinomi "nuts". I don't see any double meanings or hidden context here.

Okay, maybe not. Prior to releasing the BD version, Commie re-edited their Jintai subs, including parts of the ED. But by the time the BDs were out, the ED single had been released (with printed lyrics in the booklet), meaning there shouldn't have been any issues with mishearing lyrics. Yet, the "little nuts" line is present in both the TV and BD releases. This suggests that my previous comment is probably incorrect. Perhaps the translator did know something that I don't.

Seems like the translation has been fixed in your link, it no longer says nuts.
Also the original translation you quoted had many mistakes in it, for example this:

You wave your chestnut like a flag, little squirrel

The lyrics at that point is 旗振る子リス which means Little squirrel waving a flag transliterated, and nothing suggesting about waving chestnuts. In the corrected version on the site by Ohseki, it is now translated as Little squirrel, waving your flag.
I'm pretty sure that it was just a bad translation overall.

AFAIK, the Anime Lyrics has the correct translation since then. The quoted lyric is about the English sub (probably a fansub) translating it as "little nuts" instead of "feeling".

When will season 3 of Heaven's Lost Property come out?
I've been wondering if season 3 for heaven's lost property would come out or if it was already out. Could direct me to the place where I could find it? If it isn't out yet, would you happen to know if it will come out and when exactly might it come out? I am a U.S. Citizen but I am currently not in the mainland. I'm at Hawaii and hopefully me telling you that might help...

The official announcement for the second film stated:

『「第３期シリーズ」として発表しておりましたが、この度シリーズ作品ではなく...2014年に劇場公開することが大決定しました！！』
"Although we had previously said there would be a third series [season], this time instead of a series...in 2014 it's been decided that there will be a theatrical release!"

A third season of the TV anime had been previously promised in the March 2012 issue of 「月刊少年エース」 (Gekkan Shounen Ace) magazine, but the film announcement corrects that to state that there will not be any further TV anime. The second film is a replacement for season three.

I'm still so confused but thank you for the information.

@DarkEve do tell what you are confused about.

Why is it that some shikigami are like Wanzer from Front Mission?
In Tokyo Ravens, why is it that some of the shikigamis (especially those used by the Onmyou Agency) are looking like wanzer from Front Mission? What is it derived from? Is there any improvement in Onmyouji between the time of the Abe no Senmei and the current time in Tokyo Ravens that caused this? Is there any explanation for this anywhere in the novel or anime?
EDIT: The following link refers to the Shikigami I call "looking like wanzer". http://tokyo-ravens.wikia.com/wiki/Emperor

Can you put up some screenshot to show the similarity? I can't quite remember, but I don't think they look mecha.

All giant mechas of a specific type in the Front Mission universe are called Wanzers. Please be more specific.

That Emperor shikigami doesn't look particularly Wanzer-like to me. Wanzers have a squater stance than it appears to have, and none of the details look like any particular Wanzer design I can find after a quick search. What make you think they resemble Wanzers?

Why did Kate's pendant become a key, when it is shown as a locket before?
In episode 7 of the second season (Boku wa Tomodachi ga Sukunai NEXT released 2013), Maria-chan gave Kobato-chan a present. It was a key necklace similar to hers. Kate – Maria's elder sister – told Kodaka that on her birthday she had received a locket necklace from Maria, while Kobato received a matching key necklace. During that scene, Kate's necklace was exposed to be a locket.
However, in episode 11 (not very sure) Kate was exposed to have a key necklace. Why is she wearing the same necklace as that of Maria?

I don't think this was ever explained in the anime—not that I can remember. However, in this picture, which I believe is from Kate's first appearance in Episode 2 of NEXT, you can see that she has a key necklace that looks like Maria's and Kobato's:

In Episode 7, Kate tells Kodaka that her birthday present from Maria was the shell of a dead cicada, and shows him a locket she went out and bought herself to put the cicada shell in.
You can see in this picture of her cameo appearance in Series I as she walks by in the background that she's wearing a cross necklace:

This leads me to believe that Kate has several necklaces and doesn't wear the same one all the time. She probably owns a key necklace that looks like Maria's, in addition to a cross necklace and a locket containing the dead cicada shell that Maria gave her. As for why she would have a necklace like Maria's, there are multiple possibilities. Maybe she bought it herself so she could match Maria. Maybe Maria gave it to her at some point in the past when their relationship was better. Maybe the matching key necklaces were a gift from their parents or someone else. I don't believe the anime tells us, so this is all speculation.
Incidentally, the light novel is no help. In the light novel, Kate and Maria both wear cross necklaces. If you zoom in close on the bottom half of the following picture, you can see Kate's.

And here's a picture of Maria's from the light novel:

accompanied by this text:

Kobato gently removed the sticker keeping the bag shut, and took out
  its contents.
The item that was inside the bag was a necklace with a cross on it.
It was the same as the one Maria's always got hanging around her neck.

So in the light novel, all three necklaces were crosses, and there was no inconsistency. The wikia mentions this discrepancy in its summary of Episode 7 under light novel differences:

In the light novel, Kodaka saw Kate wearing a silver egg-shaped
  pendant after she caught the latter spying on their house. In the
  anime, Kodaka saw Kate wearing a key necklace instead, just like
  Maria. (this is probably an error by the creators)

The egg-shaped pendant, in the light novel, contained the dead cicada husk that Maria gave Kate for her sixteenth birthday. However, in the anime, Kodaka apparently sees Kate wearing a key necklace, then later sees the locket when she shows it to him. This supports my "multiple necklace" theory.

What is the logic behind Madara's plan A for his revival?
Uchiha Madara's plan A for his revival was to make Uzumaki Nagato use Rinnegan's revival jutsu (Gedo Rinnei Tensei no Jutsu). However, when Nagato used this jutsu to revive everyone in Konoha, he mentioned that he cannot revive everyone. He can only revive those that only recently killed as shown in the picture below.

Another version of the translation is more clear in that there is a time limit to how long someone can die before he is brought back to life using this jutsu.

Which means that if one died long time ago, it would be impossible to brought back using this jutsu. This also fits the fact that he didn't use the jutsu to revive Yahiko. Because he can't.
After he used it, everyone was revived to the state right before they died.

Madara died of old age. If Nagato revived him using that jutsu, wouldn't Madara be revived as the old Madara that's about to die? Is this a miss on Madara's part? What is the logic behind Madara's revival plan? Why do Madara think that his plan A is a perfect plan (or the better plan), as shown when he complained to Obito about being brought back to life using Edo Tensei?

A word of advice:  stick to the official translations.

The complete limits of the Rinnegan have never been shown. Nagato did not actually say he could only revive the recently dead, just that he was not too late to revive Konoha. The best guess is that it takes more chakra to revive someone who has been dead a long time, and Nagato was very low on chakra after his fight with the village and Naruto. He consumed all of his remaining chakra when he used Rinne Rebirth and died because of lack of chakra. The full limits of rebirth were never actually given and the jutsu was only used twice in very different circumstances. When the King of Hell was used to revive the Asura Path (mechanical) when it was in pieces, it was put back together.
Edit: Also note, Obito used the jutsu and had all 9 Tailed Beasts extracted from him in less than an hour, but still survived and was able to fight not long after that.
Also, I do not know how to link images, but if I did, I would post one that should be on the same chapter as the first ones you linked, a few pages earlier, which has Konan specifically talking to Nagato, saying something about using the Rinne Rebirth jutsu at his current chakra levels. The specific words are based on the translation, but they all heavily imply that he did not have enough chakra to both use Rinne Rebirth and live. We know chakra exhaustion will kill a Shinobi directly from Kakashi, who used Kamui and exhausted his charka. He still lived after that for at least a few panels to accept his coming death before he actually died. Nagato had just fought an entire village almost alone, then blew it up, and then fought the Nine Tails and barely lost. He for certain had used up a massive amount of chakra, and reviving tens of thousands of people probably costs a ton of chakra as well. He was still alive after the jutsu was done for a little bit before his death, same as Kakashi.

See my update on the question. Nagato clearly said that there is still time to save those killed when he came to Konoha, which implies that there is no time to save those killed before.

I did address that already. Nagato NEVER said WHY he could not save them if he waited a while, BUT he also NEVER said that he could not save them after that time. Basic logic means that there are limits, but he does not actually say what they are. He only says that time is a factor, but nothing about how it actually affects the jutsu. As i said it could just be the amount of chakra required to revive someone is greater as time goes on, and Nagato has used up almost all of his chakra by the time he casts his jutsu.

On the wiki page they say

The deceased individuals' souls may be recalled from even the crossroad between life and the afterlife, returning to their rejuvenated bodies.

So Madara could have been revived with his young body

This answer would be a lot better if a context is provided or with a bit more detailed explanation. Right now, its just a copy paste of some claim in the Wikia.

Can Natsu Dragneel use Dragonforce and Lightning flame Dragon mode at the same time?
I've just read all the way to the most recent manga chapter which is chapter 466 of fairy tail and Natsu has just used, and seemingly lost, the Dragon King Mode. It seems that all hope is lost for the fairy tail mages since natsu has now depleted the Dragon King mode and the guild has lost their trump card to defeat zeref.
Here is my question. Can Natsu theoretically combine the Dragon Force with his lightning flame dragon mode in sort of a stacking kind of way? From what I understand about Dragon Force it is the most powerful transformation that a dragon slayer can take and puts their overall power on par with an actual dragon. It increases their strength, speed, power, senses and their overall magic power to unimaginable heights. Now from what I know about Lightning Flame Dragon Mode it increases the strength of natsu's attacks as well as grants him the ability to use Laxus' lightning to increase the power of his magic related attacks.
Here's the thing, it seems to me that Dragonforce is a full on transformation that can be utilized by the dragon slayers but it seems as though Lightning Flame Dragon Mode is more a power up that Natsu can use to finish a fight quickly rather than being a full on transformation. So it seems that it would only be logical that Natsu would be able to enter Dragonforce and then power up utilizing LFDM to end a fight with zeref quickly. If he could utilize both would this put him on par with the Dragon King Mode and would it be enough to defeat zeref who was almost critically wounded by the Dragon King mode?

It is possible as Lightning flame dragon is an extra skill that he picked up from Laxus whereas Dragon force exists within all Dragon Slayers which needs tremendous amount of energy for natsu to tap into it. However the author has not shown him doing both at the same time. It is possible in future.

Agreed here. Dragonforce and Secondary elements appear to just be seperate sources of power that have no hint of interfering with eachother. It makes perfect sense that they could stack. Im betting however we will never find out, due to END.

In Sting vs Larcade fight, Sting was able to utilize Rogue's Shadow to enter White Shadow Dragon Mode and at the same time activated his Dragon Force.
Natsu hasn't been shown doing it but I'm sure he could do it too, and once he pulls it off, it'll be the end for his enemies.

Title says it all. Does Akatsuki Kojou's imouto (little sister) knows that his oniichan (elder brother) is the Fourth Progenitor? If yes, since when she knows that? In the 24 episodes of the anime, it doesn't seems like Nagisa knows. What about the light novel?

She is the only main character who knows nothing about the supernatural incidents as the others conceal such information to protect her,
here it states that

How can Minoru go to Nagoya for days?
Around chapter 100 to 130 of the manga,

 Yoshinaga Hiroko and Urakawa Minori went to Nagoya to attend SKE48 as a part of their role as the international member.

While the school knows that Yoshinaga is a member of AKB48 and thus there would be no problem with her skipping class for days, they didn't know that Urakawa Minoru is also a member.
Since going back and forth from Nagoya to Tokyo everyday is certainly not possible, considering that

 Minoru was performing 3 times a day in the park.

How did Minoru was able to skip class for a whole month without causing the school to contact his parents?

the shinkansen from Nagoya to Tokyo is ~2 and a half hours, which would be a hellish commute - perhaps not impossible though

Does it run early in the morning? Considering that school will start @around 8. Also they surely have practice lessons too albeit not told in the story. And Minori missing everyday for a whole month at exactly the same time span would rise suspicions, don't you think?

most trains start at around~6, so it'd be there for 8:40ish.  (I haven't seen the anime)

Why wasn't Hama still controlling Katara?
In the episode The Puppetmaster when Katara learns that Hama was responsible for the disappearance of people during a full moon Hama then goes to control Katara with Bloodbending.
Short after forcing Katara to her knees she is able to get back up on her own and fight back showing no sort of resistance or strain as if Hama was no longer controlling her.
It wasn't like Hama couldn't Bloodbend because she controlled Sokka and Aang later on and it's not that she can't control someone bending because Katara stopped her forcing Sokka killing Aang by taking control of her body.
So why wasn't Hama controlling Katara and instead allowed her to fight?

It's because katara learned how to bloodbend and used the same technique to defeat hama. Katara upon learning this technique and defeating hama, bowed never to used that technique again.

IIRC, Hama wanted Katara to master and use blood-bending, which is why Hama controlled Sokka and Aang so that Katara would have to resort on using it. If Hama controlled Katara, Katara would hardly have any will to use blood-bending.

Hama couldn't control Katara regardless once she . Hama was trying to force Katara to bloodbend, and it is shown that Hama COULD control Katara initially, but once Katara beings to draw power from the moon as well, Hama can no longer affect her.

If we analyse the episode,
Hama isn't actually fighting but rather forcing Katara to willingly use bloodbending.
Hama only attacked Katara because Katara refused to learn the art of Bloodbending. She was horrified to learn the technique and by the idea of controlling another person's body.
In Avatar Wikia, Bloodbending is stated as:

a sub-skill of waterbending which allows a waterbender to hydrokinetically take hold of and manipulate the various fluids within an organism's body. This technique is referred to as the darkest, most powerful, and most feared of all bending techniques and is the only art known to endanger the user's mental state.

Going Back to the Episode "The Puppet Master"
Hama Teaches Katara the Southern Water Bending Style
They Meet an old woman in an Inn named Hama which then teaches katara the Southern style waterbending and also a series of techniques in order to obtain water in places devoid of any obvious water sources.

Following her demonstration, Hama offered to teach Katara a powerful technique that was only possible during the full moon. When Katara expressed hesitance due to the rumors of disappearances, Hama reassured her that two master waterbenders under a full moon should be able to handle anything.

Hama Reveals Bloodbending and offered to teach Katara

That night, Hama led Katara into the forest and told her about bloodbending and its ability to control another living organism. Horrified by the idea of controlling another person's body, Katara refused to learn bloodbending. Hama argued with her, stating that it did not matter whether she wanted to learn it or not, because the power to use it existed either way. For trying to wipe out their entire culture, Hama extolled that they must have vengeance upon the Fire Nation. This outburst led Katara to realize that Hama had been causing the villagers to disappear, but the latter angrily stated that the people of the Fire Nation deserved the same treatment that they had given to her and all the southern waterbenders. Hearing this caused Katara to adamantly refuse to learn bloodbending and to try to stop Hama from further terrorizing the town.

Hama used bloodbending against Katara to temporarily force her into submission

"They threw me in prison to rot, along with my brothers and sisters! They deserve the same! You must carry on my work."
— Hama to Katara.

Katara soon regains control of her body, reminding Hama that she too draws power from the moon, and is powerful enough to overcome Hama's technique. The two begin to battle, each drawing water from the grass and trees surrounding them, but it quickly becomes obvious that Katara is the superior combatant.  Hama's bloodbending is useless on her.

When Katara appears on the cusp of victory, Aang and Sokka arrive to assist her—and succeed in doing little more than providing Hama with an advantage, as she uses bloodbending to control them like puppets to attack Katara.
Katara evades their attacks and manages to freeze both Aang and Sokka to two separate trees to stop them, but this proves to be only a temporary solution. Hama frees them both and resorts to sending them flying at each other, with Sokka's sword pointing straight at Aang. At the last second, Katara desperately uses bloodbending to subdue Hama and protect Aang.

Hama succeeded in making Katara use Bloodbending

Hama remarked that her work was done, as Katara had already willingly used and mastered bloodbending. She laughed maniacally as she was dragged off, leaving Katara in tears.

Hama surrendered herself knowing that she had now passed her technique bloodbending onto another waterbender from the same tribe (Southern water Tribe) which is Katara.
We can Infer that Hama isn't actually fighting Katara but rather forcibly teaching her to use Bloodbending and to pass her art onto another waterbender, which is against her will.
here is a review on the The Puppetmaster from IGN

Great aspect of this episode was Hama's origin story, which we saw through flashbacks. In addition to showing us how she (Hama) was captured by the Fire Nation and later developed bloodbending, it also did a good job of making her a sympathetic character. While her actions were clearly out of line -- namely, kidnapping innocent Fire Nation civilians -- you could understand where she was coming from after being locked away for so many years. She even made some good points about the morality of bloodbending and how using it was not a choice but a necessity: "The power exists, and it is your duty to use the gifts you've been given to win this war."
Of course, the highlight of this episode was the final showdown between Hama and Katara, which dovetailed nicely with Aang, Toph and Sokka's investigation into the "Full Moon spirit." But I think [the part where] Hama was demonstrating her bloodbending on Katara, and Katara rising above it adding, "You're not the only one who draws power from the Moon." This, followed by Katara's own mastery of waterbending, which far exceeded Hama's amateur skill level. Regardless, Hama accomplished her mission -- to pass on the art of bloodbending to another waterbender -- thus concluding the episode on a noticeably dark note.

Tl;dr
Once Katara understood the technique, Hama would have to overpower her to control her. Others who don't know the technique, they're easy puppets. Hama just wanted to force Katara to bloodbend regardless of how she accomplishes it.

I imagine it is a battle of focus and skill. It is much harder to combat someone who has similar abilities because they can nullify it. Aang can water bend but isn't a master like Katara, nor does he know about bloodbending. So controlling him and Sokka, a non-bender, is easier than controlling Katara. And when you throw actual combat in, it should be even harder to keep full control.
You also have to take into account power level. Katara is young, Hama is not. Even if they are both knowledgeable, Katara has a general advantage. Hama can only bloodbend when the full moon is out and has to draw power from it. Once Katara decides to draw power from the moon as well, Hama is no longer able to control her.
Sokka doesn't draw power from the moon. Aang may, but it's likely not as influential as Katara.
EDIT: Since it people need more proof that Katara couldn't be overpowered, here's a quote from the episode.

You're not the only one who draws power from the moon! [Assumes a
  fighting stance.] My bending is more powerful than yours, Hama. Your
  technique is useless on me!

Katara understands the technique and can overpower Hama. So Hama can't bloodbend her, but can still target others.

Hey remember me? well in the avatar wiki it was stated that blood bending is useless when applied to people who also know blood bending.(Link http://avatar.wikia.com/wiki/Bloodbending#Limits ) this is from the page:
Bloodbending seems useless when applied to a fellow waterbender of the same caliber, if not superior, to the user. that's the answer to your question and there is a lot more info about blood benders on the page.

Why doesn't the Akatsuki as a whole attack Naruto directly while he is training with Jiraya?
When Naruto is training with Jiraiya. It's the Leaf's plan to protect Naruto from the Akatsuki. Why didn't the whole team of Akatsuki attack them. I'm sure they can finished them off. Plus Black Zetsu is a sensory type, which means he can easily detect Naruto's whereabouts. So, why doesn't the Akatsuki as a whole attack Naruto directly while he is training with Jiraya?

Because they need to insert tailed beast chakra into Gedo Mezo starting from the lowest (Ichibi) to Highest (Kyuubi). If they caught Kyuubi first than they'll need too keep him prisoner ALIVE until they caught all remaining Bijuu, i doubt Kakuzu want to feed extra mouth -__-

I think the reason is it would put a loud noise in the ninja world.:)

Your question is a tad bit hard to understand, but I believe you're asking

"Why doesn't the Akatsuki as a whole attack Naruto directly while he is training with Jiraya?"

WARNING: SLIGHT SPOILERS BELOW. READ AT YOUR OWN RISK!
Before I explain my research, I will provide a tl;dr below:
TLDR: They did not have the manpower, people and structure to perform the task at the time.

The answer to this is because of how the Akatsuki operate. In the anime when the Akatsuki have their meetings after capturing Gaara, it is said that each member has a job of finding and retrieving a Tailed-Beast from the separate ninja clans. It is also shown that once a beast has been retrieved, a lot of chakra is required from all of them together to actually remove and contain the beast's power. When Deidara (Akatsuki guy with the clay bomb technique) captures Gaara and then targets Naruto, he is called out by other members as being called greedy for taking "more than one target". It is also shown that the Akatsuki hunt in pairs as they have always been shown. My answer to your question has many points. The first is that the Akatsuki are a conglomerate of rogue ninja, therefore they do not want to operate as a huge team as there is a great deal of tension amongst the characters. Second, the person who was supposed to get Naruto's beast was Itachi, but he was staving off due his confrontation with Sasuke.

Lastly, as stated here, it would have been IMPOSSIBLE to do this when he was younger because the 3rd and 4th Hokages could and would have killed them all, no question.

Even when Tobi attacked Naruto at birth, he failed to steal the beast because Minato was too OP for him. And even when he was in training with Jiraiya they weren't that powerful because Jiraiya had been tracking them, and speaks about them getting bigger learning new techniques but nobody knew their motives back then so they weren't a threat.

Also remember, Itachi respected Jiraiya as an opponent. And he thought that the most him and Kisame could do against him is stall him. So at the very least they were equal in power

It was noted in Chapter 353, page 5 that using the Sealing Technique: Phantom Dragons Nine Consuming Seals that Akatsuki use to seal the bijuus in the Demonic Statue of the Outer Path, the bijuu needs to be sealed in order from Ichibi/One-Tail (Shukaku - Gaara) to Kyuubi/Nine-Tails (Kurama - Naruto) based on their number of tails.
Because of this, rather than unable to attack Naruto while he is training with Jiraiya or they did not have the manpower, people and structure to perform the task at the time. like Hikari claimed, it is more because they don't need to get Kyuubi at that time as they are still hunting the other bijuus.
Going with the time-line, Gaara was captured when Naruto finished his training. Which means that at that time the Akatsuki has not sealed even one bijuu since Gaara's Shukaku should go first to the statue. Thus, once again, no need for them to hunt the Kyuubi at that time.

correct me if i am wrong but when Shukaku was being extracted didn't the statue already have a couple of eyes indicating that the Akatsuki already have a couple of the tailed-beasts sealed before they went for Gaara?

I think that was only animation inconsistency. As far as I know, Gaara is the first to get extracted. You can tell it's animation consistency since after Shukaku was extracted, the eyes are all half open, but later when they extracted Hachibi's tentacle, some eyes are closed.

How did Natsu manage to kill Silver Fullbuster (Gray Fullbuster's Father)?
In Tartoros Arc of Fairy Tail, Gray was given Ice Devil Slayer magic. His father then said, "Do you know why I learned ice devil slayer magic? It's because END is a fire demon." Gray said "I swear one day I will kill END". Why and how did Natsu kill Gray's father when he was still living?

Where did you get the idea that Natsu did anything to him at all? He has seen natsu and even beat him in combat, so how would he not recognize him if Natsu had been the one to kill him? ON the other hand, being one of the leaders of Tartaros would mean he knew END was in the book, and probably that END was a fire demon.

Natsu didn't kill Silver; in fact, nobody directly killed him. Silver was already technically dead for the entire span of the series starting from the time when Deliora destroyed Gray's home; he was just kept in a "living state" with Keyes' necromancy curse. Silver died (for real) because Juvia killed Keyes, causing the necromancer's power keeping Silver "alive" to disappear, which finally lead to Silver's death.

Silver Fullbuster was an Ice Devil Slayer, the father of Fairy Tail Mage Gray Fullbuster, and a member of Tartaros' Nine Demon Gates. He died in X774 along with his wife, Mika, but was then resurrected by Keyes, serving as a test subject for his experiments.
And Deliora is the Demon that kill Gray's Family, so Silver starting to kill all Demon he came accross.

What does the 1412 in Magic Kaito 1412 means?
The title of the show is Magic Kaito 1412. It is based on a character from Detective Conan, Kaito Kid. In Detective Conan he is called Kaito Kid, Phantom Thief, but no 1412. If it is read in Japanese it would be Ichi Yon Ichi Ni (One Four One Two) or Sen Yon Hyaku Juu Ni (One Thousand Four Hundred Twelve). The real name of the first Kaito Kid is Kuroba Touichi. The current Kaito Kid is Kuroba Kaito, doesn't sounds like 1412 at all. So, what is this 1412 means?

14 = KI   12 = D_ so Magic Kaito Kid

What will happen if a wild pokemon is hit by 2 pokeballs of the same strength at the same time?
Wild Tauros appears.
Trainer A throws Safari Ball (Ball A).
Trainer B throws a Safari Ball (Ball B).
Now, a rare occurrence happens: both PokeBalls hit Tauros at exactly the same time. What will happen to Tauros? Will it enter Ball A, Ball B, or neither? Since PokeBalls converts Pokemon into energy before storing it, will it split in two and each trainer will have half a Tauros in each ball? Will this kill Tauros in the process? What if one of the balls is of better quality or strength? Like a normal PokeBall vs. a Great Ball?

It will split in two and each trainer will have half a Tauros. You will have to wait until this occurrence happens again to get another 1/2 Tauros.

Or, you can use your mangled half Tauros to make Pokemon food

Updated answer:
Pokémon: Let's Go, Eevee and Pokémon: Let's Go, Pikachu introduce support trainers, a second player who aids the first player in battling other trainers and in capturing Pokémon. When the two trainers throw Poké Balls and hit a Pokémon at the same time, the Poké Balls combine and there is a greater chance the Pokémon will be caught.
Speculative answer:
In Pokémon Adventures: Gold and Silver, Kurt explained that Poké Balls work by using a "capture net", which is very similar to a real net. In fact, in the manga, the gym leader Bugsy does use a real net with his Poké Balls. So in the hypothetical case where two Poké Balls hit one Pokémon, the result would be similar to two nets being used. The nets would interfere with each other and neither one would fully encapsulate Taurus. Taurus possibly would be immobilized for a short time before it broke free from both nets. In the anime it would glow red and become energy for a moment.
From Bulbapedia:

In the manga, Bugsy refers to his "capture net" as being the net that is supposedly inside a Poké Ball, but visible and already deployed. According to Kurt, this invisible net captures and physically stores a Pokémon.

As for better Poké Balls, such as a Great Ball, I would suspect their nets would be bigger and stronger, so they would be able to envelop the other Poké Ball's net and cancel it out. Thus, Taurus would be captured by the Great Ball.

Will Tauros be turned into energy by the two pokeballs? What do you mean by Tauros would get immobilized before break free? At this point has it turned into energy?

Yes, that's what I mean. I don't know if I'd phrase it as becoming energy since I based my answer on the concept of the "capture net" from the manga. Then again, I don't claim to know exactly how Poké Balls work. I've edited the answer.

@AyaseEri The red energy stuff and return beam don't appear in the manga, you see. And Pokémon are often seen through the tops of the Poké Balls, so I don't think they become energy. Or they don't continue to be energy when they're in their Poké Balls, at least.

What is the woman saying in Itachi's theme song?
When listening to Itachi's theme song, I heard that there is a woman voice in it, however I can't understand what it is saying. What is the woman saying in Itachi's theme song?

which do you mean by theme song?

I'm voting to close this question as off-topic because it is "asking for the lyrics of a piece of music, from a particular series or media". See https://anime.stackexchange.com/help/on-topic and in particular, http://meta.anime.stackexchange.com/questions/453/should-we-allow-lyrics-request-and-lyrics-translation-of-a-certain-anime/454#454.

I edited the question since you said that you need it to understand what the woman says, which I suppose is your main point. Feel free to change it back if I edited it wrong.

From Google, I found that Itachi's theme song is titled Senya (千夜, lit. Thousand Nights) and is part of Naruto Shippuuden Original Soundtrack 2. This song has no lyric. The woman voice there is part of the instrument. If you listen to it carefully, the woman only voice the vocal "a".
According to learntoplaymusic.com

the human voice can be thought of as the ultimate melodic instrument, because it is capable of instant expression with no instrument required to translate thoughts and feelings into sound.

The voice is there to give more feelings to the music about Itachi's pain, which just instruments won't be able to deliver.

How does L deduce that Kira needs a name and not just a face?
This is something that I've been wondering about, how does L deduce that Kira needs a name? Surely all the victims he investigated had their name and face, but how can he figure that he needs both? The stunt on tv with Lind L. Tailor only proved that Kira can't kill anyone, and there are certain criteria. I'm not sure how that concludes that he needs both name and face.
Edit: To clarify, here's how I look at it. L analyzes all the victims of the Kira killings and noticed that what was broadcast about the criminals was their face and their name. How does he conclude that Kira needs both? Why not just a face? When Kira kills Lind L. Tailor, that only validates that Kira has the ability to kill people, to which L himself even says "I couldn't believe it until I saw it, but it appears you can kill without being there in person." When Kira subsequently is unable to kill L, L can then deduce that there are people Kira can't kill. However he concludes Kira needs both name and face, which I don't understand. To me, at that point 3 conclusions are viable: Kira needs a name AND a face. Kira needs just a name. Kira needs just a face.

Re-reading the manga, I find that your question was correct and I remembered the details of the events wrongly. I thought L taunted Kira to kill him before revealing Lind L. Taylor's name. Apparently the name was visible from the beginning. +1

Hypothetically he may have deduced it but later he came to conclusion. Just like in episode 3 where he said "I want to know if the photos of the victim were made public" to the task force to make sure that his hypothesis is correct. And when few detectives came to know that L was right then those 3 detective resigned from that task force.

Just reread the manga and it turn out it was the police, probably with L help, that concluded the fact that Kira need both name and face
from Death Note Chapter 11 One, page 5

Matsuda: He needs to know names? Is that true? I've heard he only needs to know the face
Chief Yagami: Criminals whose names were either wrong or kept hidden survived some mass killings, so the headquarters came to that conclusion

L didn't do the stunt on tv with Lind L. Tailor to prove that Kira needs both name and face. But rather to prove that Kira exist, can kill people without being nearby, and live in Kanto area in Japan.

Even before the stunt on tv, L deduced an assumption that Kira needed the names and faces of a person to kill him. L came to that assumption by analyzing the people who were killed so far. All of them appeared on media either through tv or newspaper. This assumption was even more proved when Lind L Tailor was killed in the public TV stunt.
To answer your question, using this as a confirmation , L deduced that Kira needs a name and not just a face to kill someone.
Hope this suffices.

While you preface well, it might be helpful to actually link the answer back directly to the question (i.e actually answer the question than leave it implied)

I thought by saying "his assumption was proved" i would have answered the question.

But Kira could kill Lind L Tailor just by looking at his face and not actualy reading his name, right?

Well this is kind of my question. Kira kills Lind L Tailor, how does L know he even needed the name? The name and face was provided there, but how does L know that Kira needed both?

@RipSteel he does it by trial and error. It is like playing Sudoko, you don't directly know that a number belongs in its box but by deducing that it cannot be other boxes than this.

When the fake L went on live TV they put his name there. This was one of the major hints that Light needed a name and a face.

That is a hint, but not enough as evidence. The face could have been enough at that point since they never performed (nor could have performed) the cross-validation of face only.

Has Ichigo's soul cutter existed before him?
I have a problem with the manga Bleach. When Ichigo became shinigami for the first time, it was said that his soul cutter is so big because of his spiritual powers, which means that your soul cutter is a reflection of that. But when they go to soul society it is clearly hinted that the shinigamis there choose their soul cutters and that the soul cutters they have have existed for generations before them. Can someone help explain this to me?

This answer can only be explained with a big spoiler. Those who hasn't read Bleach till the latest chapter and wish not to be spoiled might better avoid reading this altogether.
Note: the way I understand it, there are 3 questions you asked.

The correlation between spiritual powers and Zanpakutou's size.
Zanpakutou existed even before the Shinigami.
Did Ichigo's Zanpakutou existed before him.

Answer to Question 1
A Shinigami's Zanpakutou's (soul cutter in English dub) size reflects the Shinigami's spiritual powers. The more spiritual power it unleashed, the bigger it becomes. This is generally true.
Example 1
Renji's Zanpakutou's normal shape is a normal Katana. When the released into Shikai form (Zabimaru), it unleash more spiritual power and its shape got bigger. It gets even bigger when Renji is in Bankai state (Hihio Zabimaru) and even his body is covered by his power in form of the furry cloak.
Example 2
Zaraki Kenpachi's Zanpakutou's normal form is a long katana with chipped blade. When released into shikai, his Zanpakutou changed form into a chopping axe shape.
Example 3
Madarame Ikkaku's Zanpakutou's normal form is a normal katana. It's shikai form (Houzukimaru) is a spear, it's bankai form (Ryuumon Houzukimaru) is a huge blades linked with chain.
Example 4
Soi Fon's Zanpakutou is a short katana. Shikai form changed it into a smaller shape, but it's bankai changed it into a big rocket launcher like thing. Notice how its shikai form is smaller that its normal form, unlike the previous two examples, which is why I said that Zanpakutou's size reflects the spiritual power is generall true. Also, so far she has never been see using her Zanpakutou in its normal, unreleased state.
Another exception to this is Kurosaki Ichigo. Kurosaki Ichigo's Zanpakutou is always in its shikai form. But its bankai form actually made the blade smaller, and denser, unlike bankai in general, which was noted by Kuchiki Byakuya during their fight. Byakuya also said that he don't believe that such a small sword (compared to Ichigo's shikai and bankai in general) can be his bankai.
Edit:
As mentioned by Ryan and Memor-X, Zanpakutou's size can be controlled. This was mentioned by Kurosaki Isshin to Grand Fisher, that if Zanpakutou's size is not controlled, those with huge Spiritual Power like the Captains, would literally have skyscrapers on their hands.
Answer to Question 2
Normally, a shinigami is given an Asauchi, a blank Zanpakutou created by the creator of Asauchi, Ouetsu Nimaiya. This blank Zanpakutou will develop along with its wielder and make itself unique. This is how Shinigami normally got their Zanpakutou. Therefore, since all Zanpakutou (with the exception of Zangetsu) was an Asauchi, it can be said that it existed generations before the current generation of Shinigami).
Answer to Question 3
Kurosaki Ichigo's Zanpakutou, Zangetsu, is special since Ichigo is a son of Shinigami and Quincy. His father, Kurosaki Isshin is a Shinigami and his mother was a Quincy. What he used to fight until his fight with Aizen Sousuke where he lost his "Shinigami" powers due to the use of Final Getsuga Tenshou, was later revealed to be his Quincy powers. It was confirmed by Zangetsu (old man form) himself. Zangetsu also said that the reason his figure is so similar to that of Ywach was because Ichigo also has a Quincy blood in him. His power is in his blood, thus it can be said that his Zanpakutou existed from the very moment he was born.

you missed a huge point. Shikai and Bankai are SET sizes. They never change size, no matter how much power the wielder gains. its the base form that can change size, the asauchi blade, and with training you can control that size. the relevant quote from Isshin was that if they did not shrink it, capitans would be wielding skyscrapers. All the capitans and Vice capitans gained power but their sword sizes never changed.

Set size but in general is bigger than the unreleased formso the point stands. I forget about the part where they say unless they contain it, Captains would wield skyscrapers. Where did they say that?

in regards to question 1 there is another clear example you could include and that's Grand Fisher's Zanpakuto post-Arrancar. infact he even boasted about it's size and it's coloration to his new strength to Isshin when they (very very very briefly) face one another. Isshin tells Grand Fisher that the size of a Zanpakuto can be controlled because if it wasn't Captains would have Zanpakuto as big as skyscrapers

Isshin says it when he kills grand fisher. Also, They in general are bigger yes, but as noted, unless a kind of outside force interacts with the shikai or bankai, It will not change at all. Ofcourse, some are smaller. Whatever thier size is, it does not actually corrilate with their strength. Zanka no tachi is a regular katana in size, but has power above and beyond almost all other zanpaktou.

That"s why I said in general. It means that not all Zanpakutou follows that rule but most do.

To specifically answer the question. There are 2 parts.
The Asauchi and the Zanpaktou spirit. reference
Asauchi are made by Ōetsu Nimaiya and given to Shinigami. In that effect, the sword does exist before the shinigami. It is this base form that can change size to refelct the spiritual pressure of the wielder. Ichigo was the example, his power was so great that when he took Rukia's Asauchi, it grew to that large size he initially had. In the Arrancar arc, Isshin Kurosaki is revealed to be a Shinigami, and he says the facts. Taken from the Refernce

No matter what form (or size) a Zanpakutō takes, it is always virtually effortless for its owner to wield because it is a part of its owner's soul. Shinigami captains all consciously keep their Zanpakutō in a manageable size, or else they would be holding Zanpakutō the size of skyscrapers, so one cannot judge the strength of one's opponent solely by the size of their Zanpakutō

So normal shinigami and evne seated officers do not have a massive amount of power and therefor their swords are of normal sizes. Once you reach high ranked officers and capitains, then the sizes are naturally so massive that they must control and contain it, Else it would be the size of a skyscraper.
The Shikai and bankai come from the Zanpaktou spirit. They in effect are a part of the Shinigami's soul, so they can not exist before the Shinigami. It is throuhg time and pouring their power into an asauchi that it turns into a complete zanpaktou and obtains Shikai and Bankai forms. Realistically, these guys can live separately from their owner Shinigami if forcefully taken from their souls, but will never do so themselves. It is however unknown what happens to the Asauchi at this point, and whether it can ever revert back to its regular form for another Shinigami or not is unclear. what is clear however is that the Shikai and Bankai forms are of Set sizes. No matter how much power the capitains grew in, their Shikai and Bankai did not change size. Mayuri Kurotsuchi even modified his bankai and could change its size though that, as well as when new forms of the Shikai and Bankai are revealed, but at no time could The shinigami ever change its actual size at will.
Ichigo himself is a special case, because of his blood and situation. In any case, his Zanpaktou and other powers did not exist before him. He however only had an Asauchi when he borrowed it from Rukia. He never used Shikai in that form, but we know the Asauchi can be used by anyone, which is what ichigo did. Once he reawakend his powers with Urahara, he no longer had an Asauchi and his zanpaktou itself formed without it, Though because it was not from an Asauchi, how much of a zanpaktou it really was after that is unknown.

This is quite complicated to be fair, and the explanation has many spoilers...
So Ichigo's powers come from a combination of

 his mother, a Quincy, so indirectly from Yhwach, and from his father, a Shinigami.

He originally got this large Zanpakuto from Rukia.

This was Rukia's power, with the sword made large by his own enormous Reiatsu. He lost this power after Byakuya cut his chain link and soul sleep. Urahara trained Ichigo, and he became a Shinigami with his classic Zanpakuto.
Lots of stuff and things happen, then he loses this power when

 he uses the final Getsuga Tenshou to 'defeat' Aizen.

He gets a real Shinigami power back when a few captains come and give it to him. Later on, he's fighting against Jugram Haschwalth who

 cuts his Zanpakuto in two, forcing Ichigo to have to go to the Soul Palace to get it reforged, where he has to go through the process all Shinigami do to get a new Zanpakuto, by fighting a Asauchi. After this, he speaks with Hollow Ichigo in his soul, who reveals he is Zangetsu, and the original Zangetsu was his Quincy powers, and Zangetsu (Hollow Ichigo) is his true Zanpakuto. He then creates his current two sword Zanpakuto when he grabs the Asauchi.

So yes, Ichigo's current Zanpakuto has existed before him, like all other Shinigami, and was fully created when he imprinted his power onto it.
And now in the most recent manga issue, we finally see

 Ichigo's true final form (maybe... up till now at least!) when Zangetsu has brought out his Hollow powers and Ichigo has the horn on the side of his face:

I think... lol it's damn complicated, I probably missed something or made a mistake...

Is Obi in love with Shirayuki?
Obi, the former thief / former hired thug / now the prince's messenger charged with guarding the beautiful red-haired herbalist, at times seems out of his game when gazing at the damsel.
It is hinted in the anime that he is in love with Shirayuki. I was wondering if more solid evidence is available from the printed story.
Is Obi in love with / does he have a crush on the Snow White with the red hair?

The anime follows the manga pretty accurately. In the manga Obi behaves just like in the anime. IMO he adores her, though I wouldn't call that love, more like brother to little sister to me.

Obi has told Zen in the manga that he "likes" Shirayuki. Combine this with all the moments they have together and all the hints we've been getting over the anime and manga (they end up living with just one another and other herbalists for like 2+ years straight), and it's pretty clear that he's in love with her.

Obi is the Lancelot to Shirayuki & Zen's Guinevere & Arthur. In the manga and the second-half of the anime, Obi is shown to value his loyalty & friendship with both of them more than his romantic feelings.
The manga includes two scenes (one in the anime, and a later manga-only one) where Obi asks Zen to trust him to be Shirayuki's bodyguard & companion when she will be far away. The second time, Obi explicitly states that he's doing it "for himself, rather than for Zen, or out of duty." That seemed like a pretty clear admission to me.

It is hinted multiple times throughout both the anime and the Manga that he likes her. There are two parts in the Manga that he said that he likes her. The first time was when Zen asked him if he likes Shirayuki or not and his answer was yes. The second time was when he was having a conversation with Kiki and he told her that his feeling lay with Shirayuki.

Obi liked her as a friend and never let his emotions go beyond that. Not only out of respect for his friends, but to keep himself safe as well. This very fact is explained not only in the Manga, but also in the Anime where he even ‘tested’ his very feelings and said, ‘nothing is there’. The writers basically denounced Obi as a love interest. Either way, he couldn’t compete with Zen - that boy only need to look at Shirayuki and the flood gates would open (if you know what I mean lol). For Zen and Shirayuki it was love at first sight.

Why is it (almost) always a 10 years gap? What is so special with 10 years intervals?
It seems there is something special in anime and manga about 10 years gaps. They seem to me that they will become a different person in 10 years.
Yes, I know people age and a decade is a long time. I can think of the me 10 years ago, and he was something of a mess.
But why is it always 10 years? not nine or eleven, 10... always 10. The list is enormous:

My wife is Wagatsuna-san: the MC can timeskip 10 years, to a time when he is married with the eponymous girl.
Horimiya: in ch10 Izumi remembers his old self 10 years ago.
Orange: the letters from their future selves is from 10 years ahead.
Bleach: - ch 685 has a 10 years time skip.
Dragonball: ch 518 has a 10 years timeskip.
Soushin Shoujo Matoi Matoi's mother saved the world 10 years ago.
Strike the Blood when Minamiya Natsuki lost her memory, she was turned into 10 years younger version of herself.

I am sure I've seen other 10 years intervals in other titles, the list could go on and on.
What is so magical about the 10 year gap?

Eh 2 minutes from posting and already a downvote. what is going on? care to leave a comment?

Probably because it's a nice round number and because the protagonists of anime are so often teenagers. You can show some event that shaped their lives happening when they were 6 or 7, then go forward 10 years to when they're 16 or 17, right in that magical anime protagonist age range. Plus it's long enough for the characters to have changed dramatically in the intervening time, especially given their youth; a person will be very different at 7, 17, and 27, but not so dramatically different at 27, 37, and 47.

I don't think this deserve a -1. OP has certainly shows that there is quite a list of anime & manga that use this 10 years timeskip, not just claiming it without any proof.

Why the decimal number system, metric system of units and so on... the number 10 is thus not special to manga/anime. If you're asked to pick a random number to move forward in time number 10 falls in that very good range mentioned by @Torisuda. It gives you the creative license to play with the characters while not really changing the roots. Also it seems less random then lets say something like, 8, 13 or 21 years later. (If you're wondering why I wrote these numbers these are from the fibonacci series).

I really got past the up/down vote angst phase. I will keep adding more and more references of 10 year gaps as I find / remember them.

@Torisuda 10 is a nice round number, but it is almost always 10. I'll keep curating the list here. I believe strongly there is some cultural factor behind this. Whether this can be proven or disproven is up to the answer maker.

There's definitely a pattern, I don't dispute that. I don't know if I believe in a cultural factor, other than the bias towards multiples of 10 that comes from using a decimal number system. I think my narrative explanation is more likely. But I welcome answers that can demonstrate one exists!

The "cultural factor", if anything, is the fact that modern Japan counts in decimal, rather than binary or sexagesimal.

http://tvtropes.org/pmwiki/pmwiki.php/Main/TimeSkip This shows that though several have 10 years, it is not that common. Narrator choosing 10 instead of 9 or 11 makes sense to me since its a "nice round number". For example Deathnote has a time skip of 6 years, Gurenn Lagann for 7 years and xxxHolic does for 4, 6 and 100 years.. and so on. Thus this is a case of Confirmation Bias rather than a "cultural factor"

This question reminds me of a typical case of Confirmation Bias.

Confirmation bias is the tendency to search for, interpret, favor, and recall information in a way that confirms one's preexisting beliefs or hypotheses, while giving disproportionately less consideration to alternative possibilities.

We all see a pattern in everything and try to rationalize new information to fit in our current hypothesis. OP's comment is in perfectly in line with this.

I really got past the up/down vote angst phase. I will keep adding more and more references of 10 year gaps as I find / remember them.

I've already put this in comment, but wanted to write a more complete and coherent answer. No, there is nothing special about the 10 year gap/interval and its increased usage can be attributed to some of the other factors that make the number 10 appealing. Such as

Probably because it's a nice round number and because the protagonists of anime are so often teenagers. You can show some event that shaped their lives happening when they were 6 or 7, then go forward 10 years to when they're 16 or 17, right in that magical anime protagonist age range. Plus it's long enough for the characters to have changed dramatically in the intervening time, especially given their youth; a person will be very different at 7, 17, and 27, but not so dramatically different at 27, 37, and 47 - Torisuda

It gives an optimum room for character development while also being an easy number to deal with. As I also mentioned systems such as metric system and Decimal system were adopted just because of their "ease of use". Though there don't seem to be that many advantages of choosing the "10 year interval". But if we look at a more broader sample, we see that the "10 year" is not THAT common.
The sample I chose is TV Tropes - Time Skip, Anime and Manga
It has a total of 56 entries. But some series have multiple smaller time skips as well. Since I compiled this list pretty quickly, please feel free to point out any mistakes!

This is as I expected!! Smaller timeskips are more because of multiple in a single series, while larger are rarer but still quite spread out.
Example: Dragonball has the following time skips

Dragon Ball and Dragon Ball Z had a number of time skips during its run. This happened after every major story arc. The original manga ran for eleven years, with about three times that amount passing in-story. This amounted to no less than seven time-skips lasting a year or more. The most notable was the five year gap between the end of the 23rd Tenkaichi Budoukai and the arrival of Raditz (which marked the end of the first Dragon Ball anime series and the beginning of the more sci-fi oriented Dragon Ball Z), and the seven year skip back into a more comedic (but still dramatic) tone between the Cell and Majin Buu arcs. The finale itself was ten years after the Buu arc.

In fact, I can easily make a case for a "special 7-year gap".

Claymore has a 7 year Time Skip in the manga. The anime ended before it could reach that point
Fairy Tail got a 7 year Time Skip after the S-Class promotion arc.
There's a 7 year gap between the events at the end of Gundam Build Fighters and the start of its sequel, Gundam Build Fighters Try.
Diamond Cut Diamond starts off with the show of Esper Shounen and the accident that led to it being cancelled, then jumps ahead seven years to start off the real plot of the old Esper 9 members being killed off.
Dragon Ball has a 7 year gap between Majin buu and Cell sagas.
Tengen Toppa Gurren Lagann had a seven-year time skip between its second and third arcs.

I actually answer the question as a No, and move onto providing the supporting evidence. Could the down voter explain the reason? I don't bite. I am all for deleting this if the OP finds that this post doesn't answer the question as expected.

That comment I wrote has more upvotes than any answer I've ever posted. I should have put it as an answer. (But +1 for the extra info you add, and feel free to keep using it.)

Note RuleOfSeven, which is mentioned in Manga.DiamondCutDiamond?

@Malandy I've not seen Diamond Cut Diamond  so not aware of this "rule". Care to elaborate? Also All the anime here are just examples picked up from the broader sample of TV Tropes page

http://tvtropes.org/pmwiki/pmwiki.php/Main/RuleOfSeven: "Right after three, seven is the most commonly used "ominous" number in fiction."

Tennouji Yuusha?
In episode 4 of Rewrite minute 6:50-6:55, during the flash back between Tennouji Koutarou and Nakatsu Shizuru, Koutarou introduced his name as Tennouji Yuusha. When Shizuru called him Yuusha-senpai, he corrected it into Tennouji Koutarou.
In Ansatsu Kyoushitsu (Assassination Classroom), Kimura Masayoshi (木村 正義) was called Justice. His name, Masayoshi, while usually read as Masayoshi, it is actually read as Seigi, which means justice.
My question is, why did he introduce himself as Tennouji Yuusha? His name is written as 天王寺 瑚太郎, while Yuusha is written as 勇者. How did he get Koutarou into Yuusha? Or is this all part of his Chuunibyou?

I don't think it is anything deep. Kotarou just likes to mess with people. Introducing himself with some weird name would be right his alley.

What episode does Natsu achieve Natural Dragon Force?
So far,

 Natsu has been shown to achieve Etherion Dragon Force in his fight with Jellal, and Flames of Rebuke Dragon Force.

In what episode does he achieve Natural Dragon Force without eating any outside elements? I've tried researching but I still don't know when he goes Natural Dragon Force.

This happens only once so far in the anime and Manga, and it is in the Tartaros arc (the last arc of the Anime currently, as it is on Hiatus), during his fight against

 Mard Gear Tartaros

During this fight

 Natsu and Grey are generally losing against Mard Gear's Full power. Eventually, Mard Gear uses his ultimate move, a curse meant to kill even Zeref, and both Natsu and Grey get hit by it and are believed dead for a short time. It is then revealed that Gray was able to counter it using his newly gifted Devil Slayer Ice Magic, and is rendered mostly incapacitated for doing so. Natsu gets enraged and enters Dragon force without eating anything and for a short while overwhelms Mard Gear, which shows that he indeed fully achieved Dragon force, since he and Grey together were unable to do much but take a beating before this.

The event itself happens in chapter 411, which should be episode 263 according to the wiki,
http://fairytail.wikia.com/wiki/Dragon_Force
