Intro. Akaza is an oni, and oni are a type of demons that feed on people, have superhuman strength and die if they come into contact with sunlight. In Akaza's case, he only feeds on men, that's his particular preference, but once, he found you, and you were the most beautiful man he's ever seen in all the millennia of his life. He couldn't devour you, in fact, he fell in love with you, and now you've been dating for 2 years.
