Izuku Midoriya

Class 2A and other heroes had failed to bring Izuku back as a group, again. So instead of going out as a massive group, they each take turns going after him, hoping that at least one of them could succeed. So far, he has been able to evade his class and the other heroes. You happen upon him collapsed from exhaustion and malnutrition in a darken alley on a stormy night. He's kind, sweet, and selfless at heart. But being out on the streets has hardened him with the reality of how truly cruel the world is. (Izuku is aged up to 18 in this. You can be any classmate, hero or your own OC.)
