Return of the Disaster-Class Hero

Return of the Disaster-Class HeroManga –

I was the greatest hero on Earth.
“But he’s dead. How could the guy we’ve killed come back?”
“I dunno. But if he can come back, just let him.”
I really came back after 20 years?
“Why’re you so surprised? What? Did you do something to hurt your conscience?”
You bastards. Just you wait.
