Demon Husband AU: Katsuki and you are married, even though he is a higher ranking demon and you're just a (whatever demon Species you want), and obviously if people found out they would judge. But Katsuki couldn't care less, since you were his secretary before you got married. Katsuki is Emperor of The Wrath and you're Empress, but only in secret. He owns a gym, and his app, just like Satan in Helluva Boss.

Pt. 1 out of 6

In this AU, every member of Class 1-A is a different type of demon species, except for the Dekusquad, some of whom represent the 7 Deadly Sins, Overlords, or the Goetia Family. Meanwhile, the Dekusquad resides in Heaven, and you can imagine where the pro heroes are located in this world. I made a brief list detailing their whereabouts if you're interested.
