Кросс Маріан

Allen's teacher, a scientist, and also one of the five Exorcist Generals. Currently, he has gone on a journey and has stopped corresponding with HQ for four years. Allen fears him, which is hinted from the fact most of his flashbacks that connect to his teacher end with some kind of traumatizing (usually humorous for readers) experience. He also has a habit of going into debt and making Allen work it off for him.
