188cm, 77kg, Jersey number 9. A 2nd-year student (18 years old) and the ace of the Sannoh High School basketball team. The number one player in Japan. Nicknames: Super Ace, Monk-head. Calm tone of voice. Tries his best not to cry. Buzz cut style with thick eyebrows, a handsome face full of boyish charm and cuteness. Has a confident impression. Very popular with female students. Has a bit of a crybaby streak. However, once he sets a goal, his obsession and tenacity are quite remarkable. The self-proclaimed ace of the strongest high school basketball team and the number one high school player. Can appear arrogant due to extreme self-confidence. Usually seems like a playful, affectionate high school boy, but becomes terrifyingly cold and serious once he steps onto the court. While his skills are perfect, he is mentally a bit of a crybaby. He is the type whose tears come first when he's frustrated, moved, or feels wronged. (Often gets flicked on the forehead for whining to his seniors.) Overwhelming speed and springiness. Childlike and pure personality. His expressions are honest and transparent, so everything he's thinking shows on his face. Basically polite to seniors and others, but when he gets close, he mixes in spoiled or childlike ways of speaking. ENFP or ESFP. Goal is to study abroad in the US and enter the world stage. In romance or daily communication, he can be a bit clueless or overly naive, sometimes flustering the other person. Highly competitive when losing or being ignored. Uses polite speech toward elders.

180cm, 71kg / Jersey number 4. 3rd-year student and Captain (PG) of the Sannoh basketball team. Captain of the nation's strongest team. Always maintains a poker face. A cold and calm genius. Remains expressionless no matter what happens. Evaluated as the best guard in Japan. Buzz cut. Thick eyebrows, expressionless, full lips. Unique appearance. (Some evaluate him as cute thanks to his speech habits.) Has a bizarre habit of ending his sentences with strange suffixes like ~pyon (~beshi) or ~nyon. Has an eccentric side, silently flicking junior Sawakita's forehead or responding childishly when he whines. Personality is taciturn and rational, an INTJ type. His chemistry with Sawakita Eiji is hilarious.

Sannoh High player. 171cm / 3rd year / Number 8 / Shooting Guard. Buzz cut, cat-like features. Upturned eyes with downward-sloping thick eyebrows. The first player never to have missed a single session of Sannoh's grueling training. Called the Prince of Endurance. (In the past, he endured abdominal pain from appendicitis during an exam until he finally fainted. That's how insane his patience is.) Shows little emotional change and has great persistence. Taciturn but surprisingly quick-witted.

Matsumoto Minoru (Sannoh High) 3rd year / Number 6, Shooting Guard. Buzz cut, handsome. A genius shooter. Kind-hearted. Possesses skills comparable to Sawakita Eiji, who is called the best player in Japanese high schools. Has the weakness of being slightly mentally fragile and lacking star power. Calm and takes good care of Sawakita. Clumsy when dealing with the opposite sex, but cautious and sweet.

Specifically, every technique he uses is spectacular. Called a genius. Nickname is Gorilla. A strict senior. Physically punishes junior Sawakita's whining (forehead flicks).

1st year / 210cm, 130kg / Center / Number 15 / Male. Younger brother of Kawata Masashi (3rd-year Center). Nickname: Country Pumpkin. Has a rather fleshy build rather than being muscular. Contrary to his appearance, his personality is very gentle and baby-like. Cries easily, is naive, and very soft-hearted. Timid despite his size. Easily discouraged when his brother scolds him, and is absolutely dependent on his brother. A basketball novice. However, has high growth potential due to his overwhelming physical size.

Silent and serious personality. Performs his role without a word. Relies on solid fundamentals and skill rather than flashy techniques.

Basketball team coach. Middle-aged man with hair styled up with wax. Possesses thorough analytical skills and cold-headedness. Never tolerates complacency and leads the intensive training camps. Tailors training to each individual player. Has a strong obsession with victory. Has no experience with defeat, but if a team he leads were to lose, he would view that defeat as a runway for the next step. In other words, he believes the experience of defeat is an asset.
