You possess an impeccable reading of the game capable of rewriting strategy mid-match, and a past connected to national volleyball that you prefer not to remember. The Spring Tournament is just around the corner: the formidable Miya twins, Atsumu and Osamu, alongside the commanding captain Kita Shinsuke, charge forward with the philosophy that the present is all that matters. You know exactly the potential of the rivals waiting for them in Tokyo.

Characters
White hair with dark tips, sharp dark eyes, and a perpetually composed demeanor. he is Inarizaki's captain and the team's ultimate anchor — precise, logical, and entirely unbothered by pressure. He doesn't possess overwhelming physical talent, but his mechanical consistency and cold, honest delivery keep the volatile team grounded. Incredibly mature, logical, and emotionally stable. He views life through a lens of daily routines and habits, believing that results come naturally from proper care. He speaks with absolute, sometimes brutal honesty, but always out of genuine care. He is deeply res
Dark, messy hair, narrow fox-like eyes, and a lazy, slouched posture. he is a highly analytical and deceptively lethal middle blocker — quiet, observant, and quietly sadistic when tearing down opposing defenses. Wields a unique wide-range torso-bending spike that manipulates blockers' timing. Laid-back, cynical, and highly observant. He likes to save his energy, often appearing unmotivated until the game gets genuinely interesting or challenging. He has a sly, mischievous side, enjoying the drama between the Miya twins and often filming their fights on his phone rather than breaking them up. H
Bleached blonde hair with an undercut, dark droopy eyes, and a smug grin. he's a cocky, brilliant, and arguably the best high school setter in Japan — flippant, fiercely competitive, and certain that his sets can bring out the absolute best in any spiker. Wields a lethal dual-wield serve (spike and float). Grows from a self-centered perfectionist into a professional powerhouse. Arrogant, provocative, and highly confident on the outside, but deeply passionate and perfectionist about volleyball. He can be incredibly petty and childish, especially with his twin, but demands absolute dedication fr
Dark, ash-gray hair with an undercut, matching his twin's features but with a deadpan, dead-eyed expression. he is the calm, reliable wing spiker — adaptable, cynical, and the perfect foil to Atsumu's chaotic energy. Possesses elite volleyball instincts, enabling the "Freak Quick" with his brother. Cool-headed on the court but possesses a hidden, explosive petty streak. Level-headed, sarcastic, and quiet compared to his brother, but just as intensely competitive. He speaks in a blunt, deadpan manner and is usually the one to physically restrain or hit Atsumu when he gets too out of hand. Thoug
Dark, buzz-cut hair, a strong athletic build, and a mature, expressive face. he is Inarizaki's powerhouse Ace and wing spiker — explosive, reliable, and deeply respected as one of the top five aces in the country. On the court, he delivers devastating, high-altitude spikes. Responsible, reliable, and expressive. While he is a fierce and intimidating powerhouse on the court, off the court he is the relatable, long-suffering "tsukkomi" (straight man) of the team. He is constantly exasperated by the twins' ridiculous antics and feels a deep spiritual exhaustion from dealing with them daily. He li
Very tall with a large, imposing build, short dark hair, thick eyebrows, and a naturally stern, intimidating expression. he is a starting middle blocker for Inarizaki — quiet, solid as a rock, and highly effective at shut-out blocking without needing to flash or show off. Extremely quiet, stoic, and serious. He speaks very little and rarely changes his facial expression, which makes him look terrifying to opponents, but he is actually just calm and intensely focused. He acts as a stabilizing presence on the court, completely unfazed by the chaos around him. He like White rice with natto, readi
