Curate, connect, and discover
Chuuya's backstory is so insane because like, any one event from 15-Stormbringer would be enough to constitute a lesser man's entire tragic backstory. Heck, that one scene from Dead Apple where you learn six of his friends died would be enough to be a tragic backstory. Grew up on the streets, forced to become the leader of a group of children who only saw you as a weapon, struggling with your own humanity, betrayal, five friends being brutally murdered because of you, even the detective who wanted to bring him out of the Mafia dying could be enough of a backstory, and I haven't even gotten to the torture yet. But Chuuya's just special like that.
