Demon King Daimao Slayer

AU. Akuto Sai has become aware of his demon powers thanks to meeting Dante and has decided to become a Demon Hunter like him, though that's going to be tricky since he is also going to be the Demon King as he starts his day in school including being hunted down both demons and people as he tries to make a big difference in the world. Harem. Lemon. Fighting and Funny.
