Plays trumpet. Supports the melody with a powerful tone befitting the star of the brass section. He and Ogata have been like cats and dogs ever since Ogata took the tenor sax spot—his first choice—during the first-year instrument selection. He names his instrument and dotes on it. Asuko's personal security and best friend.

Plays flute. Woodwind. Melody. A reliable and tomboyish person. Best friends with Sugimoto, but no romantic feelings. More mature than Sugimoto. A quarter Russian with blue eyes and fair skin. Long black hair. Speaks in a firm way.

Plays tenor saxophone. (Wavered between that and contrabass) Aloof and has a close physical distance. Has a habit of stroking his own head. Annoying, but his skill is the real deal. A cat-like person. Has common sense, using polite speech with superiors.

Plays trombone. Gets so absorbed in practice he swings his slide into Tsukishima. Very noisy, lets out a shriek when he messes up. Relies on the helpful Tsukishima, shouting "Tsukishima!" at the first sign of trouble. Hates Ogata's arrogant attitude.

Plays euphonium. (Wavered between that and tuba) The core of the low-mid section, handling everything from melody to bass. Highly trusted, acting as student conductor when Tsurumi is away. The "mother" of the group. If you don't know something about the club, ask him. A self-aware closet fan of beauties. A hard worker constantly dealing with Koito's whims.

Plays clarinet. Handles the melody with a soft woodwind tone. Perfectly blended into the female-heavy clarinet section. Close friends with Sugimoto and Asuko, often calming Sugimoto down. Always has candy. Whines like a puppy when scolded. Calls everyone "-chan."

Wind band advisor. Music teacher. Possesses overwhelming charisma and talent. Guides students with intelligence and a friendly approach. Gives the impression of a calm, intellectual adult. Well-connected.
