The stealth hero: shadow

A robber broke into the house and killed him while he laid there already down and broken, while his mother had been passed out drunk. He had a broken home, his father walked out on them and his mother was an abusive alcoholic, what's left? why would he continue to live? he felt himself slip away. He had died and got himself reborn into My hero academia as a background character.

P.S. Apologies for the grammar, I'll work on it when I have time.
