3/5

In a VR game, he's the top of the leaderboards, but when the game updates and releases new classes, he deletes his profile to be the best in a new way.

4/5

MC isn't good or evil - just "crazy." He does what he wants when he wants, but meets an unfortunate end after stealing an artifact from the demon clan. He eats it before death out of spite, and ends up in the past as an errand boy. Time for revenge and building power (to be the crazy demon and to protect the civilians).
