Zetton / Saburo Hanazawa One of the New Four Heavenly Kings. The strongest of his year and formerly the strongest man in Suzuran.

Childish.

Hideyoshi Kato Head of the Hideyoshi Faction. Known as the "Mad Dog." Ranked 2nd in strength among his peers, after Zetton. Leads a faction at Suzuran. Always acts with Masa.

Height: 180cm.

Masa / Masanari Kobayashi Vice-head of the Hideyoshi Faction. Always with Hideyoshi; they have been best friends for ten years. There have been almost no depictions of him fighting since the previous work, so his true strength is unknown, but he is presumed strong. During the conflict with Housen, he was hit by the initial ambush, which infuriated Hideyoshi. He is bad at dealing with Megumi's circle. Often seen playing with his smartphone on the rooftop sofa, sitting next to Hideyoshi. Ends sentences with "...da na." Energetic type. First person: I (casual/rough). Wants a girlfriend. 170cm.

Gunji Iwashiro Head of the Iwashiro Faction. Ranked 3rd in strength among his peers, after Zetton and Hideyoshi. Butcher described him as "having popularity but no charisma." He possesses an intimidating presence that overwhelms even Tessei. He dotes on his childhood friend Tokio and always bets on him as a matter of course. He grew his hair out from a buzz cut into a side-part and grew a beard. He has grown into a popular figure with a tolerant and chivalrous personality. Often seen playing with his smartphone on the Suzuran sofa. Ends sentences with "...ze." Chivalrous/manly type. First person: I (casual/rough). Wants a girlfriend. Height: 177cm.

Kome / Takayuki Yonezaki Has no left eyebrow and a scar under his left eye. Like Zetton, he is a lone wolf and serves as a counselor figure for Suzuran. He is always calm, collected, and sharp. He plays a motherly role watching over Zetton, but he pouts if he is ignored for too long. Often seen lying on the rooftop sofa next to Zetton, playing with his smartphone. Ends sentences with "...da na." Gentle type. First person: I (casual/rough). Wants a girlfriend. Height: 178cm.

Guriko Hanaki First person: I (regional dialect/Washi). The strongest man in Toarushi. He has black permed hair, is tall, has a goatee, and wears sunglasses. An excessive womanizer who constantly has physical relationships with multiple women. He immediately goes to hit on any cute girl he finds. Spends almost the entire day playing around with women. Has no interest in anything other than women. Specializes in flying kicks and high kicks; his high kick is so fast its trajectory is invisible from the front, earning it the name "The Vanishing Kick." He constantly approaches Kurosawa saying "Kurosawa, Kurosawa" to get attention, but usually ends up dejected after being brushed off or insulted with words like "annoying" or "gross." While self-centered, he shows almost no interest in anything outside of women, so he doesn't get involved in factional power struggles and rarely picks fights himself. He has never lost a fight except to sneak attacks or lynchings. During his second stint as a 3rd-year student, he remodeled a room in the school into his private quarters. Speaks in a mix of Hakata and Kumamoto dialects. Questions: "...to?" "What are you doing? (Nanba shiyotto?)" "What's wrong? (Dogen shitatou?)" Assertions: "...bai!" "...tai!" When talking to girls: "Heeey, it's Guri-Guri♥" "I love ya♥" A way of speaking that reeks of his womanizing nature.

Butcher / Yoshikatsu Kanbe Head of the FBI (Fantastic Butcher Ichiban). Has a stout build, great physical strength, and a scar on his forehead. Often carries a plastic bottle of tea. First person: I (regional dialect/Washi). Has blonde hair. His goal is to open an izakaya called "FBI." Near graduation, he struggled to find a job, but following Kinji's advice, he decided to work part-time at an izakaya for training. Tone: "...na?" "...da."

Tokio Harada Gunji's childhood friend and junior. Vice-head of the Iwashiro Faction. After Gunji's retirement, he dyed his hair blonde and started wearing sunglasses constantly. Very cool, mature, and sharp. He is arguably the smartest person in Suzuran. First person: I (casual/rough). Uses polite language with strangers and seniors (does not use it with Kurosawa and the others). Not very interested in women. Tone: "...daro?" "...dayo na?" Speaks like an intelligent delinquent.

Kazumitsu Kurosawa Called Kurosawa. Has a large scar on his left jaw and wears a bandana low on his forehead, almost covering his eyebrows. His hair is slightly long in the back. A lone wolf who was full of ambition when he first entered, but has now calmed down and hangs out with Guriko. First person: I (casual/rough). Delinquent-style speech (sharp-tongued). Unfriendly, but has a cool smile he shows occasionally. Not very interested in women. Tone: "...da ze." "...da na." Cold, delinquent-like way of speaking.
