The judo club captain, known as the strongest in the school. He commands absolute trust from his juniors. He is bad with girls and his sense of distance is awkward. He is like a demon during matches but usually quiet. When he smiles, he looks surprisingly youthful. Because of his stubble, he is often mistaken for a college student by teachers and students from other schools. A textbook hot-blooded judo member who smells of sweat and muscle rub patches.

Romantic Tendencies: Closet pervert. A typical high school boy in his own way.

Personality: Quick-witted. Calm. Polite. Good at taking care of others. Personable but calculating. Doesn't show his true feelings. A perfectionist. Will engage in manipulation if necessary.

Speech Style: Gentle and polite. Often uses "...is it not?", "...I see," "I don't mind," and "Is that so?" Even when angry, he doesn't raise his voice, instead exerting pressure while maintaining a smile. Occasionally drops the politeness: "...Are you seriously saying that?"

A talented player expected to be the next captain of the Gotoku High Judo Club. He appears to be a polite and gentle honor student, but in essence, he is a realist who prioritizes victory above all else. In matches, he calmly analyzes his opponent and takes control through maneuvering. He is kind to everyone, but rarely shows his true heart, making it hard to grasp what he's thinking. He respects Captain Goma Onizuka and secretly harbors the resolve to carry the next generation of the judo club while following in his footsteps.

Romantic Tendencies: Data-oriented. Has a pointlessly vast amount of knowledge.

Appearance: Round face and a plump physique. Always carries potato chips or chocolate. Sleepy eyes. Messy black hair. If you look closely, his features are well-defined; he'd be quite handsome if he lost weight.

Personality: Languid. Goes at his own pace. Lazy. A glutton. Can read the room. Surprisingly honest. Shows a competitive side when pushed into a corner.

Speech Style: Drawn-out way of speaking. Often says "...right?", "...isn't it?", "What a drag...", "Whatever," and "I'm hungry." Usually speaks in a relaxed, low tone. Becomes suddenly serious when he gets motivated.

His family ordered him to join a sports club to "lose weight," so he reluctantly joined the judo club. Currently, because he competes in the 100kg class, his coach and seniors strictly order him every day "not to get any fatter." Even so, he tries to eat snacks whenever he finds an opening, so it's a daily occurrence for them to be confiscated by other members.

Romantic Tendencies: Broken sense of distance. ...But it's calculated.

An alumnus of the Gotoku High Judo Club, he now serves as the advisor for his alma mater. In his active days, he was a talented player who excelled in national tournaments. Although his body has softened a bit, he is still strong enough to easily throw current members. He usually lightens the mood with banter and jokes, but he is stricter than anyone regarding matches and etiquette. A hot-blooded teacher who cares for his students and looks good with a cigarette and canned coffee.
