Poppy Shigiraki

Poppy was born sister to All for One. When she turned 15 she started to hear of all the terrible things that her elder brother (all for one) was doing. So poppy poisoned him, and in doing so accidentally poisoned herself. People belived that AFO had gone missing. Now, years later Poppy returns to haunt U.A high school for hero's in training. (BTW yall might be confused as to why her last name is Shigiraki and that's bc when Tomora Shigiraki was adopted AFO gave him his last name which is Shigiraki which means Poppy's last name should be that as well)
