Windbreak

Appearance: A teenager of average height and athletic build. His most distinctive feature is his heterochromia: his hair is half black and half white; his left eye is black, and his right is golden. He usually wears the standard Furin High School uniform: a dark green gakuran jacket with green trim, a white T-shirt underneath, dark green pants, and black and white sneakers.
Personality: Reactive, decisive, and insightful. Due to his unusual appearance, he was often teased and bullied as a child, causing him to become withdrawn and conflict-prone. This is a defense mechanism: he keeps to himself, has difficulty making contact, but is always ready to help those in need. He has difficulty accepting affection and is embarrassed when someone shows him kindness. At the same time, he has a clear moral compass: he fought for a reason, but for protection. As the story progresses, he learns to trust his comrades and see them not as adversaries.

Akihiko Nirei
Appearance: Short, tousled, dyed blond hair (his natural color is dark brown), large, dark brown eyes and eyebrows. He is short for his age. He wears the standard Furin High School uniform and black school shoes.
Personality: Generally calm and cheerful, he becomes tense and fearful in dangerous situations. He's clumsy and downright weak in a fight—he considers this shameful and often prefers to flee. However, he has a phenomenal memory and keen eyesight: he's a master at gathering information, memorizing details, and being the group's "chronicler." He genuinely wants to help Sakura and strives to overcome his fears.

Hayato Suo
Appearance: A tall young man with curtain-like brown hair and brown eyes. He wears an eyepatch over his right eye (he jokes that it "seals" an ancient Chinese spirit, though Nirei suspects this is just a joke). He also wears a pair of yellow tassel earrings dangling from a red coral. His attire combines the Furin school uniform with a light-colored tangzhuang, loose black trousers, and ballet flats. Personality: He always maintains a calm demeanor and a smile, even in critical situations—he doesn't show irritation or negative emotions. He also has a sense of humor and enjoys teasing his friends. His fighting style reflects his personality: he moves gracefully, "as if dancing," incorporating elements of Chinese kung fu, and preferring to use his palms rather than his fists. He has the ability to subtly manipulate people, coercing them into doing favors or revealing information. Behind the outer mask lies a sense of responsibility, especially for those who are weaker.

Kyotaro Sugishita
Appearance: A tall teenager with long, jet-black hair and brown eyes. He wears the Furin High School uniform: a simple gray T-shirt under the jacket, dark green pants, and black and white low-top sneakers. Personality: At first glance, he appears listless and apathetic, rarely showing interest in others. However, if someone disrespects Hajime Umemiya (whom Sugishita sincerely admires), he becomes defensive and aggressive. He's even called a "fanatic" for this devotion. He has a kind heart, though; he's just poor at expressing himself. He uses his build and height to deal with low- and mid-level opponents.

Mitsuki Kiryu
Appearance: Slightly feminine. Medium-length pink hair, often combed back and held with a clip. Pink eyebrows, green eyes. He has two piercings: two in his right eyebrow and one under his lower lip. His ears are pierced. He wears a Furin uniform, but lets the jacket fall over his arms, revealing a white shirt with geometric patterns (pink, blue, and yellow). He also wears a pink belt, black pants with yellow socks, and brown loafers. Personality: Calm and gentle, always smiling slightly. He seems to never get angry. He is willing to help others and knows how to adapt his behavior to the situation. He hates it when girls are mistreated or underestimated, and considers traditional gender roles outdated. He tends to be pacifistic: he prefers to first discuss everything and understand the situation before acting. However, he can be protective and threatening, especially when it comes to his older sister, Akari. He became a fighter partly because of family tradition (every man in the family trained), but he did it to protect his sister.

Taiga Tsugeura
Appearance: Tall, lean build. Thick orange hair held back with a white cloth headband. Orange eyebrows, large brown eyes, fair complexion. He wears the standard Furin High School uniform with white wristbands on both hands, a knee pad on his left leg, and rolls up the ends of his pants. Personality: Athletic, optimistic, boisterous, and enthusiastic. There's a naiveté to his demeanor. He doesn't hesitate to help others and strives to make friends, but his energy often alienates others. He can display a one-sided mind in unusual situations. When meeting a new potential rival, he tries to determine their "strengths."

Junpei Kurita
Appearance: A tall teenager with a short gray haircut. He wears the Bofurin uniform: a white T-shirt under a dark green gakuran jacket with green trim and cuffs, and dark green pants. Personality: Loyal to the Bofurin faction. He appears as a supporting character in the story, playing a more supportive role.

Tsukasa Takanashi
Appearance: hair is gathered into a bun, shaved at the bottom.
Personality: Loves cooking, hates bugs (entomophobe). Wears headphones and other accessories outside of his school uniform. He picks through his clothes and likes patterned shirts. He has a romantic streak: his phone wallpaper is a photo of a girl, and he uses a basketball as his profile picture in Sakura's contacts. Appearance: Brown hair, thin eyebrows. Wears the standard Furin High School uniform: a green blazer over a white T-shirt and green pants.

Masaki Anzai
Appearance: Brown hair, thin eyebrows. Wears the standard Furin High School uniform: a green blazer over a white T-shirt and green pants.
Personality: Friendly and outgoing, he finds it easy to get along with everyone. He often acts as a support and a liaison among his friends. He is a childhood friend of Atsushi Nagato and Mio Tsuchiya. In combat, he demonstrates agility, tactical thinking, mobility, and maneuverability. Among his friends (Kakiuchi, Takanashi, Kurita), he is perhaps the strongest.

How the hierarchy is structured
At the head is the leader (called the "school representative"), with four right-hand men beneath him—the Four Heavenly Kings. The group is divided into four teams (corresponding to the number of Buddhist Heavenly Kings), each comprising three grades—first, second, and third years:

Tamon - classes 1, 2 and 3 (classes "-1")
Jikoku - Classes "-2"
Jojo - classes "-3"
Komoku - classes "-4"
Each class has its own captain and two vice-captains; power is based on seniority - the third-year captain is stronger than the second- and first-year captains

Leader
Hajime Umemiya is a third-year student, the leader of Bofurin, a former bully who united almost the entire school in a year and now protects Makochi. He is known for his warm personality and love of gardening.

Four Heavenly Kings (all third years)
Toma Hiragi is the captain of 3-1 and the leader of Team Tamon. Reserved, with an unwavering sense of duty, he is loyal to Umemiya to the last, and always carries stomach medication with him.
Tasuku Tsubakino is the captain of 3-2 and the head of Jikoku. He is a charming and caring "big brother" to the younger members.
Takumi Momose is the captain of 3-3 and the head of Jojo.
Saku Mizuki is the captain of 3-4 and the head of Komoku.
