He is a regular high school student who has a curse that he calls "Absolute Choice". This curse will at random times cause a voice in his head to give him two or more choices to make. If he doesn't choose one of them soon after, he will start getting a severe headache, forcing him to choose one.

Ouka affectionately calls him "Amachi."
