[DeathkaiserG]

It want to see a story of a super OP character who got fed-up with the drama, accusations and conspiracy.

Then he just stopped and let the apocalypse happen... but because he is so OP, he wasn't affected at all. And he lives his life on his own tune. meeting all kinds of people who survived. Including the ones to pushed him to insanity.

Something like Casshern Sins style.
