The perfect TBATE

Kiyotaka ayanokouji, the fourth generation demon and the perfect human. He went by many names, and some admired him while others despised him, but no one could deny his abilities. They either despised him for being unattainable or admired him for being so. That dreaded existence, however, died... And he reincarnated as Arthur Leywin's brother in the beginning after the end. This was his chance, he thought, to enjoy the independence he craved. Kiyotaka Ayanokouji must overcome every challenge that comes his way, each one more difficult than the last, in a world where power is everything and deities walk among mortals.
