Secretagentmittens got a simple before and after of Mirko from My Hero Academia, being attacked by an age regressing quirk, I wonder if it's permanent, I mean there's quirk that paralize you, turn you into a zombie, even a meatball, but they're all temporary. At least if this is for good she won't have to be involved in the grand battles she's been in near the end of the story :y
