Makoto summons a demon to grant his every twisted desire, and in exchange for getting to eat the demon's guts, Makoto will give him his life!

Makoto has long been ostracized because of his odd hobbies and a sexual kink others see as disgusting. After summoning a demon from hell called Archduke J, Makoto sells his soul to him and is reborn himself as a demon in hell. As he learns and grows in his new role, his infatuation with J turns into an obsession--an obsession to surpass the very demon who birthed him!
