When your kink involves eating a demon's guts, what else is there to do but summon a bewitching demon to feast on? 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.One day, on a whim, he tries a demon-summoning ritual and succeeds in summoning an archduke from hell named J. Makoto sells the archduke his soul and begins a new life in hell as a monster. Living among so many unique demons helps Makoto to grow into his new role. But he finds he can't ignore the feelings he's harboring for the demon who brought him to hell, the beautiful but very twisted Archduke J!
