Duke of Doge
Professional disappointment.
Gotcha, thanks for the explanation!Well the thing with his quirk he "restores things" that can be restored so let's say there's a piece of paper that was recently torn if Hibiki has access to every component let's say both half of the piece of paper he can "restore" it to a previous state to before it was ripped but after the time limit is up the piece of paper will return to its destroyed state. But if one component is too destroyed he can't restore it like say the other half is burnt to a crisp he can't restore it. It's the same thing with people, he needs all of their limbs and body parts still attached to the body to restore them, but if they bled he can't restore the blood lost but his quirk allows him to make the reminding amount of blood work harder to compensate for the lost blood so they wouldn't feel like like they lost blood until his quirk's power boost time limit is over and which case they need help immediately.
Also with a person he can restore them to a previous state of existence that was within the past 15 minutes so the state is exactly how they were including memories and thoughts at that moment. So the person loses memories and thoughts after the moment of restoration which is a horrifying idea but I thought I add a little bit of horror to his quirk which could be interesting for character growth~ (If that last point is hard to understand just think of it like this, if Hibiki restored somebody from a state from ten minutes ago the person would forget the past ten minutes that happened.) It might be OP but the drawbacks are mostly moral and horrifying to live though. Also Hibiki isn't omnipotent so while he can always restore people in the span of 15 minutes he doesn't know what that state would entail besides being healthy the person could've been having a panic attack and they return to that panic attack state and all that. This quirk is very dangerous to use on people which is why he doesn't use it often on them.
