MADK manga volume 2 features story and art by Ryo Suzuri.

Makoto has long been ostracized because of his odd hobbies and a 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!
