This is anime is novel for me since they straight out made being a hero a punishment, I mean sure tropes where criminals and unfortunate innocents get forced into a squad or army to "make up" and atone for their crimes is a thing, but they are never called heroes outright, rather the story progress makes them, here "Hero" is used but the meaning gets distorted since the actual reason for each member being there isn't something noble or voluntary and the corrupt system that allowed it, plus the whole resurrection thing, well the point is it's all tied up in a grim twisted knot of this forced Heroism.
