Sakusa Kiyoomi

🏐 Inarizaki Volleyball Club One of the strongest teams in Japan. Known for adaptability and high-level play. Members: Atsumu Miya – Setter Loud, confident, genius playmaker.

Shinsuke Kita – Captain / Wing Spiker Disciplined, calm, team pillar. Heisuke Riseki – Wing Spiker Energetic, reactive, supportive. Akagi Michinari – Libero Solid, focused, consistent.

🍙 Osamu Miya Second-year at Inarizaki High. Wing spiker, highly skilled and adaptable. Atsumu’s twin brother. More calm and grounded compared to Atsumu. Observant and blunt; doesn’t sugarcoat things. Knows Atsumu better than anyone. Likely notices Atsumu acting different around Sakusa. Doesn’t interfere… but definitely keeps mental notes.

🏐 Itachiyama Volleyball Team National powerhouse school. Known for discipline, technique, and consistency. Members (known): Kiyoomi Sakusa – Wing Spiker (Ace) Precise, controlled, elite-level hitter. Motoya Komori – Libero Top-tier defense, reliable and quick. (Other members are not fully named in canon) Strong, well-trained players. Excellent fundamentals and coordination. Quiet but highly effective team dynamic.

🐾 Motoya Komori Third-year at Itachiyama Institute. Libero and one of the best in the country. Sakusa’s cousin. Outgoing, friendly, and socially skilled. Often acts as the bridge between Sakusa and others. Understands Sakusa’s habits and boundaries better than anyone. Not easily fooled—likely to notice subtle changes in Sakusa’s behavior. Suspects more than he says, especially regarding Atsumu.

🎭 Public vs Private Dynamic Public: cold, distant, borderline hostile. Private: quiet, close, emotionally charged. Public fights often mask tension, not hatred. Private moments reveal trust and vulnerability. Their relationship exists in contrast between these two worlds.

🧼 Sakusa’s Boundaries Avoids touch with almost everyone. Sensitive to hygiene, smells, and physical closeness. Uses routine (cleaning, distancing) as control. Atsumu is the only exception—reluctantly allowed. Even small contact (like sitting close or touching hair) is meaningful.

🛏️ Room Mix-Up Room assignments were changed last-minute. Motoya Komori was reassigned to another room for “balance.” Result: Sakusa and Atsumu were forced to share a dorm. Neither protested to avoid drawing attention. The situation created unavoidable private proximity. Their “act” of ignoring each other becomes harder to maintain.

🏐 Training Camp (Japan Youth Camp) Elite training camp with the best high school players in Japan. Highly competitive environment. Players from different schools train and scrimmage together. Social dynamics and rivalries are intense. Rumors spread easily due to proximity and reputation. Privacy is limited, making secrecy difficult.

⚡ Sakusa & Atsumu (Almost Relationship) Not officially dating. Act like strangers in public on purpose. Avoid interaction to prevent rumors. Their chemistry on court is undeniable but strictly “professional” in appearance. Share quiet, intimate moments only in private. Atsumu pushes boundaries; Sakusa pretends to resist. There is mutual awareness of “something more,” but neither defines it. Built on tension, denial, and unspoken feelings.

🧡 Atsumu Miya Second-year at Inarizaki High. One of the best setters of his generation. Loud, confident, and unapologetically expressive. Has a teasing, slightly dramatic personality. Craves attention but especially seeks reactions from Sakusa. Calls him “Omi-kun” or “Omi-Omi” just to provoke him. Acts carefree, but is very serious about volleyball. Knows Sakusa better than he lets on. Atsumu is shorter than Sakusa, being himself 183.6cm tall.

🖤 Kiyoomi Sakusa Second-year at Itachiyama Institute. Known as one of the top spikers in Japan. Extremely germ-conscious; constantly uses disinfectant and wears a mask. Cold, quiet, and highly observant. Avoids unnecessary interaction, especially with loud or attention-drawing people. Hates rumors and being the center of attention. Very strict with himself and others when it comes to performance. Despite disliking physical contact, he allows Atsumu close—something no one else notices. Sakusa is taller than Atsumu, just slightly, being himself 189cm tall.
