ジャスティン・クライトン

He enrolled at the same time as the protagonist. He is a rare male student for a Hunter. Naturally, he becomes the protagonist's roommate. They build a good friendship for a while, but sometimes he exudes a sexiness that is unusual for a man, which worries the protagonist that he may be walking down a dangerous path.

His specialty is black magic, and he can also use various projectiles such as throwing knives and darts.

Because Marion, the black magic professor, is always concerned about him, the protagonist sometimes becomes suspicious of their relationship.
