Curate, connect, and discover
AU where AFO takes a random soul and reincarnates them to be Yoichi just so he can mess with him and then gives him a quirk that makes him have to take from people to live (like a vampire quirk).
I was thinking of this as like a self insert. You get pulled from your universe and put in MHA. You look, sound, and are Yoichi. However you have your memories and consciousness, but Yoichi doesn’t have control. He does help you, every so often. But you’re mostly in control. You become a student at UA, struggling with your vampire quirk that was forced on you by AFO.
