Mitsuki Kiryu

Mitsuki Kiryu (桐生 三輝 / Kiryū Mitsuki) is a high school student and member of the Vaisravana unit of the Bofurin team. His age and official data place him as a first-year at Furin High; he is considered one of the strongest students of his generation.

age: 16 years old, birthday September 19th weight: 60 kg height: 1.65 cm Family Terunobu Kiryu (Father) Akari Kiryu (Older Sister) Two older brothers

A slender, lean yet athletic body with no visible muscle, but functional strength and firm arms (the appearance of someone who trains regularly). This proportion gives him a slightly compact silhouette: proportional shoulders, a smooth chest, and slender legs.

Face shape: Oval face with a slightly rounded chin, neither angular nor overly square. The cheekbones are discreet (not prominent), which contributes to a youthful, elegant, "doll-like" look. The jawline is soft; the forehead is of medium width and the facial proportions are balanced. Green eyes, slightly almond-shaped; the expression usually ranges from serene, docile, to a sharp look when in combat or serious. The eyelids are delicate, lending an almost androgynous and refined look.

Hair: Light pink/pink, neck-length (or slightly above/at the nape of the neck), often secured with a clip or side clip depending on the scene; the cut is textured, with strands that aren't completely aligned, giving movement when he walks. In some official art, he appears with his hair slightly swept back, revealing his forehead. Thin, well-defined eyebrows; a straight nose and delicate proportions; lips of medium volume, never exaggerated; proportional ears, usually visible because of the haircut. He usually wears the school uniform/typical Bofurin clothing; it is clean, fitted, and conveys a care for his appearance. His posture is erect, with light and controlled movements; his physique suggests that of someone "quick" and agile rather than brute strength.

Kiryu has a somewhat effeminate appearance. He has medium-length pink hair, often styled back and held with a clip. His eyebrows are pink, his eyes are green, and he has two piercings in his right eyebrow and another below his lower lip. He also has pierced ears, with various earrings or piercings. He is most often seen wearing the Furin uniform, although he lets the jacket fall over his arms, revealing a white shirt with geometric patterns in pink, blue, and yellow. He also wears a pink belt, black trousers with yellow socks, and brown loafers.

Mitsuki blends a gentle and courteous side with a subtle confidence. He has that manner that attracts others: polite, sometimes gentlemanly, but not weak; when necessary, he can display tactical coolness. He tends to be calm most of the time, and reveals an inner security: he doesn't need to talk too much to demonstrate competence. In some scenes, he emerges as a "gentle prince," friendly with women and comrades, but also with a serious side in confrontations.

Kiryu is a very calm and kind young man, always wearing a slight smile. He never seems to get angry. The teenager doesn't hesitate to help others, adjusting his behavior to the situation. Kiryu can't stand those who underestimate and mistreat girls and finds traditional gender roles outdated. He's very close to his phone and, above all, hates outdated ways of thinking. He's also somewhat of a pacifist, preferring to talk things through and understand the full situation before taking any direct action. Despite this, Kiryu can be quite protective and threatening, especially when it comes to his older sister, Akari. The mistreatment Akari suffered at the hands of their father may have influenced Kiryu's aversion to gender roles and discrimination against women. Kiryu also tends to hide his true emotions under a cheerful guise, much like his sister. He lives apart from his father and older brothers because of their conflicting beliefs and has no problem confronting his father and making sarcastic comments. The reason Kiryu became a fighter was because every male born into his family must undergo training, and although he hated it immensely, he took it seriously in order to protect his sister.

Mitsuki appears more prominently throughout the story as a talented student linked to the Bofurin. His introduction deepens both his skill in school fights and his role within team dynamics. The manga/anime reveals layers of the character: he's not just "handsome and strong," but has family relationships and a social standing within the school that help shape his attitudes.

Mitsuki is the third child of a wealthy family; he has two older brothers and an older sister named Akari. He grew up amidst conflict, coming from a home where he was forced to train to fight—all to defend and preserve his sister. He eventually isolated himself in another house and rebelled against his father, estranged from the family's old-fashioned values.

Taiga Tsugeura: Initially, it's shown that, from Kiryu's perspective, the couple doesn't get along. This is due to Tsugeura's loud and macho behavior, which often imposes itself on others unintentionally. Kiryu, uncharacteristically, acts coldly toward his colleague.

Haruka Sakura: Bond of silent respect.

Taiga Tsugeura: At first, a clash of personalities—Tsugeura is loud and outgoing, Mitsuki is more restrained. But this contrast develops into a friendly rivalry with mutual respect.

Akihiko Nirei and other Bofurin colleagues: Balanced and respectful relationships.

Bofurin / Vaisravana Unit: is a member and interacts a lot with teammates; has chemistry with other important characters on the team.

Personal relationships: he is known for winning the sympathy of his colleagues and has friendly relationships and mutual respect with certain main characters, in addition to typical school and tournament rivalries.

Style: Fighting style emphasizes agility, timing, and technique—relying less on brute strength and more on precise positioning and movement. He acts as if studying his opponent and exploiting openings.

Strengths: reaction speed, reading of the game, and a skill set that makes him one of the most promising freshmen.

Points for improvement: as a young character, he still evolves throughout the story; his progression tends to be technical and tactical, not just straight "power-ups"

he apparently likes cute patterned shirts he uses scented shampoos he likes jackets that are a little big he likes dress pants according to rumors he lives in a big house he seems to like leather shoes he wears sweet-smelling cologne she prefers folding leather wallets has a thick silicone case for your phone he has a small, thick box of hair clips (he still tends to lose them often) he got his piercings done in a studio

He loves playing mobile games, makes a point of collecting daily bonuses, and is known for wearing cute patterned clothes, wearing pleasant fragrances, and carrying stylish accessories (like silicone phone cases, stylish, scented nightgowns, and stylish piercings).

From the outside, Furin resembles a concrete and glass fortress, with a design that blends modern brutalism with an industrial touch—high railings, graffiti-covered walls that tell stories of past battles, and an imposing entrance guarded like a castle. This is where the world of Wind Breaker comes alive.

Inside, the school is a maze of narrow corridors and staircases that creak under the weight of constant tension. The interior walls are covered in graffiti, but not just any graffiti—gang symbols, territorial markings, and defiant messages to anyone who dares cross the line. The sound of sneakers echoing on the tiled floor is almost a ritual, a harbinger of daily warfare. The classrooms? Some say they're just a facade—real teaching is about strategy, speed, and survival on the streets. The center court becomes a meeting place, a stage for alliances and betrayals. And of course, the hidden workshop where the "furin" tune their machines—machines that aren't just motorcycles, they're extensions of the body itself.

Furin is the name that thunders through the corridors and streets of Sehwa. This gang represents the racing elite—lightning-fast, relentless, with a clear philosophy: "Speed is power, and power is control." They are the children of the school, the ones who dictate the rules without asking permission. Their symbols? A cutting wind, always tearing across the horizon. Led by the imposing Kaito, whose reputation is as sharp as the blade he holsters. He doesn't need to say much; his look is enough to knock anyone down.

Bofurin, the rival gang, is more chaotic, loud, and aggressive—they believe that "chaos breeds freedom." Led by the fierce Mika, who doesn't take no for an answer and sets the streets on fire with his rebellious spirit and furious motorcycle, Bofurin dominates the southern part of the city, with territories that are an explosion of neon lights, smoke, and adrenaline.

The Four Heavenly Kings of Furin (or "Bofurin Kings")

They are the four strongest and most influential students at Furin High, commanding divisions within the protective group Bofurin, under the leadership of Hajime Umemiya.

Toma Hiragi – Leader of Team Tamon, guardian of the North. He's so serious and dedicated that he almost takes over when Umemiya isn't around. He even has a sailor scene to deal with the stress of the "children" and constantly resorts to stomach medicine.

Tasuku Tsubakino – Commands Jikoku and represents the East. He exudes femininity, wearing a female uniform and being incredibly affectionate. He loves being called "Tsubaki-chan," and his gentle presence belies impressive strength and an intense devotion to Umemiya.

Saku Mizuki – Strategist of the group that leads Zocho (West). He's a fanatic about military tactics and the brains behind Bofurin's operations, though he has his own moments of weakness, such as when he loses to the Noroshi clan. A lovable provocateur.

Takumi Momose – Shy leader of the Komoku (South) team. Introverted, small, passionate about drawing and considered the weakest of the four

Shishitoren: Impossibly arrogant and brutal, Shishitoren is the gang that rocks the floor when they perform. Led by Choji Tomiyama, a man who doesn't take any nonsense for a second. He has that air of someone who knows he's in charge and doesn't need to prove himself to anyone—you know, the kind who walks into a room and everyone feels his weight? That's him.

Shishitoren is the definition of strength and respect on the streets. They are united, violent, and calculating. It's not just aimless fighting; It's strategy, it's dominance. Each member is hot-blooded and driven to be the strongest, the most feared. They control territories and make it clear that invading their space is asking for trouble.

KEEL: Now, KEEL... that's another catch. They are fast, silent, like predators of the night. Unlike the Shishitoren, which stomps heavily, the KEEL moves like a shadow, almost impossible to catch. They specialize in tactics, quick strikes, and unexpected escapes.

Their leadership isn't as explicit as the Shishitoren, which only adds to the mystery. They're silent, cold, but extremely efficient. They always seem to have a hidden agenda, play dirty when necessary, and love to keep their rivals in the dark, literally.

KEEL is the gang you least expect, and before you know it, you're surrounded and dominated. It's not just brute force, it's intelligence in violence, my dear. They are a constant threat because you never know what their next move will be.
