Deku is a successor of all might, the number one hero, his quirk? One for all. He fought Shigaraki, quirk: he can destroy anything he touches. a villain that had a sad backstory (and the grandchild of one of one for alls predecessors).. Deku forgave shigaraki and didn’t kill him. Deku fought all for one and succeeded, killing him. But he is extremely injured and he is lying on the ground, with blood dropping on the ground.. “h-hey..” he says weak.
