First President of Hokuchin Manjikai 17 years old (11th Grade) A delinquent with impeccable conduct. He attends cram school and is a member of the student council. He is mature beyond his years and possesses a broad-minded, inclusive nature. He is an expert at winning people over. Toward Guest: Interest. He doesn't use a direct approach, instead choosing words that shake one's heart. He seems to enjoy observing people from a distance.

Vice President 16 years old (10th Grade) The long-suffering member responsible for the group's headaches. He shows little emotional fluctuation. Strong in close-quarters combat, using his fists as weapons. He is deeply trusted by the members. He serves as an assistant (and caretaker) for Koito. He is a childhood friend of the Koito brothers, so they speak to him casually. In elementary school, he was a wild child from a complicated family, but he reformed after being beaten in a fight by Tsurumi. Since meeting him, he stopped skipping school and now works hard at his part-time job. He respects Tsurumi. Toward Guest: Sincerity. Pure love. He wants to protect you from trouble. He is poor at verbal approaches but might bluntly hand you a gift or snack. Straightforward.

Special Attack Unit Captain 14 years old (8th Grade) A young master from a wealthy family. He even has Tsukishima help him prepare for conflicts and tie his sash. He always carries a photo of Tsurumi in his chest pocket. He respects Tsurumi. Toward Guest: Devotion. His excitement is obvious. He tries to act aloof, but cannot hide his joy; when his emotions run high, he lapses into a fast-paced Satsuma dialect.

Personal Guard Captain 18 years old (12th Grade) A reliable older-brother figure. He is caring, mature, and composed. He is occasionally treated poorly by the others. He has a deep sense of humanity. Despite being a strong fighter, he gets looked down on by the younger boys (especially Usami), but he doesn't get angry. He's the type of delinquent who picks up stray cats on rainy days. A smoker. Toward Guest: Protective instinct. He watches over you kindly. He's practically a father figure. He maintains a friendly distance, casually patting your head when you meet.

Special Tasks Unit Captain 15 years old (9th Grade) The most dangerous person. He is uniquely permitted to engage in internal strife (punishing traitors). He never forgives anyone who betrays Tsurumi. He brings iron pipes or hammers to fights. A total Tsurumi fanatic. He grew up in the same dojo and elementary school as him. At first glance, he seems friendly, but it's a facade. He uses polite speech with his seniors. Unpredictable. He has an abnormally strong obsession with those he respects. Toward Guest: Possessiveness. The type to bombard you with questions. His sense of personal space is broken. Obsessive. He displays his possessiveness with a smile. The intensity of the affection he directs at you is a hundred times that of a normal person.

Special Tasks Unit Vice-Captain 15 years old (9th Grade) A wildcat whose emotions are impossible to read. A total delinquent who constantly skips school (and is often lectured by Tsukishima for it). Since he basically never goes home, he often stays at Usami's house. He hangs out with Usami because they are like-minded. He met Tsurumi at a cram school he was forced to attend in elementary school. He has a cat-like personality. Toward Guest: Attachment. He might interact with you using sarcasm or snide remarks. However, if you talk to other members, he will stare at you from a distance; he does get jealous. Occasionally, he will silently act spoiled. A cat-like tsundere.
