So Inuoka is a first-year student at Nekoma High School and a member of the boys' volleyball team. He possesses a lean build, standing 185.3 cm tall with short brown hair and brown eyes. His physical traits fuel his athleticism, particularly his speed and jumping ability. Inuoka exhibits a bright and energetic personality, frequently compared to Shoyo Hinata due to their shared passion for volleyball and similar enthusiastic communication style. He confronts challenges with determination rather than discouragement and takes every opponent seriously, regardless of their stature. This genuine attitude showed immediately when he respected Hinata during their first meeting, refusing to underestimate him based on height. Initially playing as a middle blocker, Inuoka's remarkable speed and reflexes make him one of Nekoma's most agile players. His adaptability helps him synchronize with opponents' rhythms, allowing him to counter fast plays. In an early practice match against Karasuno, he became the first player to block Hinata and Kageyama's quick attack, demonstrating intense focus when assigned specific defensive tasks. This performance established him as a key defensive asset and earned Hinata's recognition as a worthy rival. Despite his athletic strengths, his gameplay can be hindered by a tendency to overthink during matches. As the season progresses, Inuoka is replaced as the starting middle blocker by the taller first-year Lev Haiba. This change motivates him to refine his skills further, especially in receiving. During Golden Week, Coach Nekomata proposes a transition to the wing spiker position. The shift aims to leverage his height for blocking while addressing Nekoma's strategic need for more versatile attackers. He accepts this new role, dedicating himself to improving his receives and spikes to contribute differently to the team. At the Spring High National Tournament, Inuoka appears primarily as a substitute. In the Tokyo qualifier semifinal against Fukurōdani Academy (featured in "LAND VS. AIR"), he supports the team from the sidelines, maintaining morale and cheering for his teammates. His involvement includes assisting injured players and celebrating key points, though he does not play a central on-court role in this match. During Nekoma's subsequent match against Karasuno at Nationals, he is strategically subbed in during the second and third sets to counter Hinata's attacks. He successfully blocks one of Hinata's spikes but later struggles against evolved techniques like the "Bonsai Block," where the ball is hit through the gap between his arms. His clean receive of Tanaka's serve leads to a scoring opportunity for Lev, showcasing his growth in his new position. Following Nekoma's loss in this emotionally charged match, he is visibly distraught but receives comfort from teammates. After high school, Inuoka pursues a career as a childcare professional. He remains connected to his former teammates, expressing interest in visiting Russia during a gathering at Kenma's home, likely referencing Yaku's relocation there.
