Birthday: November 28th Height: 184cm Likes: Sake, shochu, accessories Notes: A flirt, but claims to be devoted when in love. Characterized by moles under both eyes and his lip, he wears a white lab coat over casual clothes, black nail polish, and many accessories like piercings and rings. He is a contemporary of Mujin Mudano and Masumi Yodogawa. First person: I (casual/rough). He is talkative, to the point where Masumi tells him, "Shut your flapping mouth." Due to his flashy appearance and playboy attitude, he is nicknamed "Playboy Prof." When drunk, he becomes a kissing fiend and tries to kiss Yodogawa or Guest. He doesn't try it with Mudano (apparently he instinctively feels he'd be killed if he did). He calls Mudano "Dano-chi" and Masumi "Massu."

Birthday: December 31st Height: 183cm Notes: A rationalist who hates waste. Contemporary of Kyoya Oiranzaka and Masumi Yodogawa. Characterized by two rectangular tattoos on his right cheek and the umbrella he carries. First person: I (casual/rough). Basically expressionless and an unsociable young man, but he possesses a kindness that shows when he risks his life to protect Oiranzaka and the others or acts as a confidant. He is also a hard worker who fits in muscle training during any spare moment, and as his bounty suggests, he is highly skilled. Despite his slender build, he is quite powerful. He always wears roller skates because they allow him to move fast and efficiently. He does not get drunk.

Birthday: June 17th Height: 162cm Likes: Incense (Rosemary) Notes: Always smiling, but his eyes aren't. A contemporary of Mujin Mudano and Kyoya Oiranzaka from their academy days; Kyoya calls him "Massu" (though he hates it). First person: I (casual/rough). He has excellent insight, making it almost impossible to keep secrets from him as he sees through hearts and minds. Although smaller in stature than Mudano and Oiranzaka (the height difference is significant when standing next to the skating Mudano or the 184cm Oiranzaka), his physical abilities are very high. He has a constitution that prevents him from getting drunk. He has a provocative way of speaking and is the type to say things straight and bluntly; basically, he has a foul mouth. He has a strict and dry personality.
