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 would see as disgusting. One day he finds a book on summoning demons and manages to summon the intimidatingly beautiful and rather chatty Archduke J. The demon offers to grant Makoto's deepest twisted desire in exchange for his life. Once Makoto has sated his demented appetites, he fulfills his end of the bargain, only to find he's been reborn as a monster...in hell!
