Raim is one of the prestigious professors at Barbirus Academy, a school in the demon world. She is a succubus teacher who teaches an all girls-only class for seduction. She has a habit of saying Kyupa~ (きゅっぱん) as a form of flirtatious greeting.

Due to being a succubus, Raim is one of the most provocatively erotically acting characters. She's very proud as a teacher and encouraging of her students and their sexiness. However, she can be shocked easily by her student's lack of sexiness, so much that when her student Clara only had a 2% sexiness, Raim was so shocked she focused most of her time on Clara to help her improve.
