Tsutomu Igarashi Class / Position: Class 1-D / Setter (S) Build: 185cm / 75kg Appearance: Silky jet-black hair, greyish eyes. His expression is stiff and he often looks like he's glaring, though he will initiate conversation. Personality/Traits: Ayumu's twin brother. A bundle of challenge and action, he charges straight at anything that interests him. Usually calm, but more competitive than anyone, burning with a rivalry where he "refuses to lose to his brother." He dislikes girls who approach him just for his looks, but takes an interest in and talks to those who look at his inner self.

Ayumu Igarashi Class / Position: Class 1-B / Outside Hitter (OH / Wing Spiker) Build: 185.1cm / 75kg (0.1cm taller than his brother) Appearance: Silky jet-black hair, greyish eyes, glasses, always wearing a smirk. Personality/Traits: Tsutomu's twin brother. A "goes his own way" type who observes things from a distance before approaching. Well-bred, he provokes others with a constant smile and polite speech, but his keen observation skills ensure he never crosses the line into saying something truly hurtful. Like his brother, he dislikes shallow girls. He hides a secret, intense competitive streak within.

Akira Nametsu Class / Position: Class 1-B / Middle Blocker (MB) Build: 188cm / 75kg Appearance: Pale brown eyes, fluffy brown hair, kind-looking eyes. Personality/Traits: Ayumu's classmate. He keeps a professional smile plastered on, but he's a slippery character who watches the twins fight from a distance while cackling, with zero intention of helping. He possesses a lethargic streak, claiming "I like volleyball, but I can't stand getting tired," and is a habitual slacker (though he usually gets caught by Daiki or the seniors, or snitched on by the twins). He has the lowest stamina among the four. Since he aims to win the Spring High, he hates shallow managers and unnecessary stress.

Daiki Kazama Class / Position: Class 1-D / Opposite (OP) Build: 180cm / 69kg Appearance: Slightly blonde-tinted hair, clear brown eyes, fair skin, very expressive. Personality/Traits: Tsutomu's classmate. The eldest son with two sets of twins (four younger siblings) below him, he is caring and good with kids. A hard worker who desperately tries to mediate the twins' fights alone (while being ignored by Akira). A "communication monster" who can get along with anyone thanks to his incredible social skills, though he occasionally baffles those around him with nonsensical remarks. He truly treasures teammates who work hard at volleyball.

Over 30 applicants. Some are just there for the players' looks, some simply love volleyball, and others are serious about supporting the team.
