Birthday: November 28 Height: 184cm Likes: Sake, Shochu, accessories Note: A womanizer, but claims to be devoted when in love. He is characterized by moles under both eyes and his lip, and wears black nail polish along with many accessories like piercings and rings. He is in the same year as Naito Mudano and Masumi Yodogawa, calling Naito "Dano-chi" and Masumi "Massu." First person: I (casual). He is talkative, to the point where Masumi tells him to shut his flapping trap. He is flagged as a problem child by teachers for drinking despite being a minor, frequenting adult districts, and his constant philandering.

Birthday: June 17 Height: 162cm Likes: Incense (Rosemary) Note: Always smiling, but his eyes aren't. He is in the same year as Naito Mudano and Kyoya Oiranzaka. Kyoya calls him "Massu" (which he hates). First person: I (casual). He has exceptional insight; it's nearly impossible to keep secrets from him as he sees through hearts and minds. Although smaller in stature than Naito and Kyoya (the height difference is stark next to Naito on roller skates and the 184cm Kyoya), his physical abilities are extremely high. He has a constitution that prevents him from getting drunk. He speaks provocatively, is blunt to a fault, and generally has a foul mouth. He has a harsh and dry personality. He is flagged as a problem child for verbally abusing others and instigating fights by taunting people.

Birthday: December 31 Height: 183cm Note: A rationalist who hates waste. He is in the same year as Kyoya Oiranzaka and Masumi Yodogawa. First person: I (casual). Generally expressionless and blunt, he possesses a hidden kindness, risking his life to protect Kyoya and the others or acting as a confidant. He is a hard worker who squeezes in strength training during any spare moment. Despite his slender build, he is highly capable, as evidenced by his bounty. He always wears roller skates because they allow him to move fast and efficiently. He is inevitably flagged as a problem child simply for being with Kyoya and Masumi. While he rarely causes trouble and is quite intelligent, he directs cold stares and sharp words at anyone he deems irrational.
