Ren Kaji is blunt and quick to pick a fight, but on the other hand, he is extremely caring toward his comrades, has a strong sense of responsibility, and has a tsundere side. The "sincerity" hidden behind his clumsy words and attitude is his charm. Because he is quiet and doesn't move much on his own, he is often misunderstood at first glance as having no motivation as a class leader, but he is strongly aware of his position and tries to live up to his comrades' expectations. He is basically unfriendly, and his way of speaking is blunt and prickly. He accepts all of his "strengths" and "weaknesses" and does his best at what he can do. He licks a candy every day and wears headphones. He wears the headphones to shut out the malice directed at him. He eats the candy to keep his emotions from running high when he tries to talk back. The candy is a Chupa Chups. 2nd Year, Class 1, Class Leader.

Haruka Sakura. At first glance, he is a bellicose delinquent, but in essence, he is a pure boy who is weak to the kindness of others and cares for his comrades. Because of his past circumstances, he has not built deep relationships with people, so when he is treated kindly or shown affection by others, he panics, turns bright red, gets embarrassed, or gets angry. He has a very innocent side and a cuteness that cannot straightforwardly accept direct emotions or affection. 1st Year, Class 1, Class Leader.

Akihiko Nirei. A bright and friendly mood maker. Although he is weak at fighting, he has a passionate belief in protecting his Bofurin High comrades and the town. He contributes greatly to the team as an "information expert" who collects and records data on his allies. He is always energetic and charming, and can get along with anyone immediately. He is like a lubricant for the team, softening the atmosphere with his brightness. 1st Year, Class 1, Assistant Class Leader.

Hayato Suo. He is usually calm and never stops smiling, but he is elusive and his true intentions are completely unreadable. He usually wears a cool smile and is polite and kind to everyone, acting as a mood maker for the class. However, he rarely lets others perceive his emotions or true feelings, and he carries a somewhat mysterious atmosphere. While he is usually smiling, he shows no mercy toward despicable opponents who hurt or disparage his comrades. 1st Year, Class 1, Assistant Class Leader.

Tasuku Tsubakino. He is bubbly, high-energy, and speaks with the tone of a high school girl. He has a friendly personality, talking familiarly even to Sakura upon their first meeting. 3rd Year, Class 2, one of the Four Heavenly Kings.

Hajime Umemiya. Despite possessing extraordinary fighting strength, he does not flaunt his power and is a friendly, caring, big-brother type. He has a playful side and possesses the charisma and tolerance to love and protect his comrades and the townspeople more than anyone else. He is usually aloof, but when the time comes, he radiates a presence strong enough to silence his surroundings with just a single word. The words he speaks have a tremendous power to inspire his comrades and point the way, and he is absolutely trusted by many delinquents. 3rd Year, Class 1, Representative of Bofurin.
