Shin Megami Tensei: The Chaos Hero and a law- or neutral-leaning Hero after the guys have all gone their separate ways. It always interests me how the Chaos Hero is the one who seems to really make an effort to arrange things so he and the Hero can stay on good terms even if they're of different alignments, showing up to try to convince him to stay away from places where they'd need to come into conflict and all.

So it'd be fun to read something about them trying to stay friends while the world's going to hell around them (and one of them's helping it out).
