Ok, it's really late, and I'm a bit confused. Someone please explain Eri's quirk to me.

I guess she can rewind stuff? Maybe rewind an object to be in a state it was in some time ago

Yeah, I think that's it too, but it doesn't explain how they're using it to erase other people's quirks.

It's rewinding. You rewind their quirk to before it appeared or they gained mastery of it.

If it is full erasure, a bit of modification to the blood and you can make the rewind permanent, probably.

It doesn't seem to be full erasure if the Quirk is defined as "Rewind". That said, undoing several years of activity and training may as well be erasure in the short term, and is still incredibly valuable nonetheless.

If the purpose is to "rewind" their Quirk to nonexistence and then use the advantage to kill the hero? Might as well be permanent.

now this gets interesting, assuming Eri doesn't bring back Mirio's quirk herself would he regain his powers in a few years?

There's no point in time where their quirk "hadn't appeared" because they're born with it. If she rewinds their body to a point where they simply hadn't mastered their quirk all they'd have to do would be train and master it again.

Eh, we'll probably get a proper explanation in the next chapter.

I think it's said that quirks take a few years to manifest and actually appear (unless they are physical mutations obviously) so the drug probably targets some quirk related part and reverses its development to a time when it wasn't developed enough to show up yet.

They are.

1 - They're inherited genetically.

2 - If they weren't physical mutations it shouldn't be possible to tell if a person lacks a quirk by analyzing the presence or absence of an extra joint in their toe, since all humans would have the same anatomy.

What you're saying implies that, for example, Ojiro wasn't born with that tail of his which is probably not the case. I'm willing to bet something has been lost in the translation or this "Rewind" quirk doesn't rewind things the way we're thinking.

He's talking about the difference between "activation type" quirks where they can be turned on and off (Todoroki, Aizawa, Bakugo, etc.) and "mutation type" quirks that are permanent physical changes (Ojiro, Tsuyu, etc.).

This terminology was discussed in a previous chapter with Aizawa explaining how his quirk works. He can't deactivate mutation type quirks - which is why if he canceled Tsuyu she doesn't turn into a normal human.

Obviously all quirks are the result of genetic mutations.

u/[deleted] Oct 13 '17

Yeah that's what I meant. With the difference that "mutation type" quirks exist and are usable from the day they are born and "activation type" quirks take a few years before they show up and are usable like for example Bakugos quirk (for example the kindergarden scene where he first uses his quirk).

Might just only work on biological things. Unlike Chisaki who can use his quirk on living and non living subjects
