** His Quirk (at least in the early stages) decays whatever he's touching ''with all of his fingers'', and by that it means he has to be touching the same unbroken surface or object with all five of his fingers at once, whereas if he touches, say, three of his fingers on a wall, while his pinky and thumb are on the ground, neither of those will decay since he isn't touching either surface or object with all five fingers. Gloves, due to how they cover each finger seperately, would be immune to decaying since they essentially create small seperate surfaces that each finger is individually touching, and by extension, since he isn't making direct contact with anything while wearing gloves, he can't decay anything until he takes them off. With his Quirk much more flexible now, it's likely this is not the case anymore, but in Decay's less controlled stages, gloves wouldn't trigger it. Another example is that if Tomura were touching someone's neck with ''four'' of his fingers, but his thumb were on their shirt, that wouldn't trigger his Quirk either. His Quirk needs a "clear path" of sorts to spread out and decay an object that is in contact with all five of his fingers, with as little distance as possible and no obstruction, and in a sense, the parts he's touching have to be "level" with each other, rather than seperated by their shape, like the finger-parts of gloves are.

* It seems that whenever someone discusses Nana Shimura’s decision to give up her son Kotaro, it’s always described as a “mistake,” and that her grandson Tenko’s corruption at the hands of OFA was to some degree a result of that mistake. But is that a fair assessment in context? We hear that Nana’s husband was murdered, which was the impetus for her giving Kotaro up for adoption. I’ve always read the implication that at that point AFO had discovered Nana as the latest bearer of OFA, and was killing off her loved ones just for the twisted pleasure, meaning her son was indeed in danger. Aside from that, Nana’s letter she wrote to Kotaro implies that she expected to die soon herself, so she would have had to take some steps to protect her son. Letting Torino or Toshinori look after Kotaro would still put him in AFO’s sights, even after her own death, so giving him up for adoption/foster care seems like the safest, if most heartbreaking option. If there is anyone else to blame for young Tenko’s corruption (aside from OFA of course), it would be Kotaro himself. Yes, as a child Kotaro wouldn’t understand his mother’s reasons for giving him up and grow bitter and angry at her and heroes in general (similarly to Kota). But I’m sorry, when we see him next he is a grown-ass adult who should have gained some understanding or insight into the circumstances of his childhood. Even if he still hates his mother, there’s no excuse for letting his mommy issues lead to abuse of his own family, which only ended up making the young Tenko more susceptible to AFO's manipulations. This is made even more damning by the fact that Kotoro still has his mother’s letter, where she explains at least some of her reasoning why she gave him up (ie: he knows she didn’t hate him or “abandon” him). Given Nana’s situation, I can’t see her doing anything other than what she did, even though AFO’s inexhaustible cruelty made her sacrifice in vain.

** [[StatingTheObvious Apparently not]]. It's been established that the teacher has lost control of her students. They may be well-behaved at home (and keep in mind that Quirk usage is legal when you're at home), but the idea that they could do anything got into their heads (likely due to the "ringleader"). Handling a kid sounds fairly easy, if not AdultFear inducing, but can you really handle one with superpowers?

*** That would ''still'' be considered illegal if we take Japan's quirk regulations into consideration, since he doesn't have a license and it wasn't under self-defense.

** Possibly RuleOfDrama. But there may be some actual explanations: It's likely Tenk simply ran away/wandered off immediately after the incident, which is possible since he was a small child in a mental breakdown. Or maybe he ''was'' under some sort of authority figure or service for a while after killing his family but somehow, easy to think due to the CrapsackWorld, ended in the streets. Last but not the least, is possible that [[TheChessmaster All For One]] was acting somehow to make make sure everything ended the way it did. As for how AFO got the hands all he would need to do was getting to watever authority was investigating and bribe them/blackmail them into giving them to him.

*** Regarding Hagakure and Yosetsu, the exam also awarded points for rescues, as well as incapacitating the robots. Hagakure is exceptionally good at stealth, so could easily slip past the boys and get people out, or hit some kind of shutoff/incapacitation device (which in the real field would be synonymous with something like a nerve strike or submission hold from stealth). Yosetsu has it even easier, in that as soon as he can touch a robot, he can Weld it to whatever it's touching (including itself). He gets the legs, the bot is completely inmmobilized, and if he gets the arms as well, it's out of action.

** It's a Japanese comic. It's only natural that the action would be centered in Japan, in the same way that American super-hero comics are focused on the US. To be fair, in the MHA universe, the US was the first nation to issue hero licesnses, and is popularly referred to as "the home of the heroes," which would seem to indicate that they have a lot (which would be natural with such a large, diverse population).

** Considering that it's been revealed that One For All is so high-maintenance that it [[spoiler:[[RapidAging drains the user's vitality]] if they have a quirk of their own in addition to it]], we have official confirmation that All Might is ''completely'' Quirkless. Not even a useless cosmetic Quirk, he has nothing.

* When talking about Haya Yuyu's design, Horikoshi said that her dyed hair would be against the dress code in a real school, but that it's fine in the story...but why mention it specifically anyway when in this particular setting you can't throw a rock at a group of people without hitting at least three characters with AmazingTechnicolorHair?
** Answering myself on this one: maybe it was to show that she has kind of a delinquent streak and that it's fine in-story precisely because of an abundance of technicolor-haired characters?

* [[spoiler: Why didn't Nao Shimura put her foot down earlier when her children were getting mistreated? And I say children because Hana knowing to deny that she wants to be a hero implies that Kotaro likely abused her in a similar manner before she learned to avoid his wrath. The moment Kotaro started locking the kids out of the house should have been Nao's cue to start the divorce process rather than waiting until her son's TraumaticSuperpowerAwakening.]]
** [[spoiler: From what I understand, Nao Shimura was in the same situation a lot of people in an abusive household are in: She was too afraid to do it/felt trapped by her circumstances, and it wasn't until things went way beyond the norm that she GrewASpine. Relationships are complicated and abusive ones, whether you are the direct victim or not, are not as simple as "Do the right thing when someone does something wrong". It is just not that simple, even in [[TruthInTelevision real life]], or we wouldn't have cases where children are abused by one parent and the other is very much ''not'' okay with it, or at least, they wouldn't go on for very long. Kotaro was clearly a very harsh and disciplined man, so likely any disobediance, even without punishment or threat, would be hard to do in his household, just by virtue of having that viewpoint hammered into your head by just living with him. That is also more likely why Hana would deny wanting to be a hero as well, even if she wasn't punished herself. That, and she would know what makes her father angry regardless, as the family clearly did know about the abuse. Essentially, living with a controlling and abusive person who has a significant place in your life, such as being your spouse, gives them influence on you, whether you like it or not, and it often either affects your thinking, restricts you in more material ways, or a combination of both. Just running/leaving is not easy for those who've lived like that, as any abused person will tell you.]]
** There's also the ValuesDissonance of what is and isn't considered abuse in Japan. To a Western audience, [[spoiler:locking your kids out of the house]] would undoubtedly be considered abuse, but it's not necessarily true in Japan. The very first chapter/episode of ''Franchise/SailorMoon'' has [[spoiler:Usagi's mother locking her out of the house for getting a bad grade on a test, but is nevertheless portrayed as a loving mother]]. It's possible that Nao might have been uncomfortable with it, but didn't actually see it as abuse.

** Adding to the above, human adoration is fickle and tempestuous.
Look at how people react even today with celebrities. When, say, a star player is on your team, they're an idol, the greatest of the greats, etc. But then they leave your team, and people turn against them, spewing hate and vitriol, burning merchandise, wishing ills on them, and so on. Once someone is no longer benefitting you and yours (heroes no longer beating back the bad guys to keep a perceived peace), people turn on them, even if their reasons are faulty. In this case, people are lashing out on the misconception that without heroes, there wouldn't be villains, and thus now that the heroes aren't winning, they're the root of the problem.

* Given how later arcs make a big deal about how strict Quirk usage laws are in Japan, such as during the Stain Arc, wouldn't someone at their Middle School step in and punish him for essentially using Explosion to intimidate Izuku? [[ValuesDissonance I get that Japan has a vastly different view on bullying and how to handle it]] but [[EarlyInstallmentWeirdness it's bizarre in retrospect]].

*** Piggybacking some the previous bullets by mentioning that Chapter 328 has All Might requesting aid from non-Japanese heroes in the fallout of the WarArc and the sole one who accepts it is from the U.S.

** Another thing that Bakugo might consider as Midoriya "looking down on him" is that Midoriya DOESN'T respond to his bullying/taunting. To someone like Bakugo, continuing to see him as something less than a hated rival is tantamount to Midoriya seeing him as beneath notice, especially since Midoriya was apparently hiding an incredibly strong Quirk. The fact that Izuku NEVER decided ti try and pick a fight or even retaliate is, to Bakugo, a slight that basically says "you're not worth my time, loser"

** Also, it may be that, in the MHA universe, Japan is considered to be the cream of the crop for Heroes. So being the #1 Hero in Japan, or being one of the most promising up-and-comers is considered a BIG deal
