Sō Inuoka is a first-year student at Nekoma High School and a member of the volleyball team, initially playing as a middle blocker. Lean-built and standing 185.3 cm tall, he ranks among the team's tallest players. Born on November 1, he wears jersey number 7. His athletic profile boasts exceptional speed, agility, and jumping power, paired with strong reflexes that let him adapt to opponents' rhythms through repeated observation. These traits make him particularly effective at blocking. He displays a bright and energetic personality, often mirroring Shoyo Hinata's enthusiasm. Inuoka approaches challenges with determination, showing serious focus during matches while maintaining passion for his position. Though not a quick thinker during games, he excels when assigned clear, specific tasks. His interactions with teammates are consistently encouraging and supportive. He exhibits no resentment when temporarily replaced as a starter, instead using it as motivation to improve. His volleyball background includes middle school experience as a middle blocker. In his first official match against Karasuno, he became the first player to block Hinata and Kageyama's quick attack, adapting to its speed after repeated exposures. This performance sparked a spirited rivalry with Hinata, as both recognized each other's abilities and pushed each other to higher levels. Their unique post-match communication style was sometimes difficult for others to follow. During summer training camps, first-year Lev Haiba replaced him as the starting regular, shifting Inuoka primarily to a supporting role. Despite this, he remained determined, focusing rigorous practice on improving his receives to regain a starting position. Coach Nekomata later proposed a position switch from middle blocker to wing spiker during Golden Week. This strategic move aimed to better utilize his height in blocking formations while accommodating Lev's development. At the Spring High Nationals, he was periodically subbed in to leverage his speed against specific opponents like Hinata. Against Karasuno, he successfully blocked one of Hinata's spikes but later struggled against evolved techniques like the "Bonsai Block." A flashback during this match confirmed his official switch to wing spiker. His clean receive of Tanaka's serve later led directly to a point scored by Lev. Following Nekoma's loss to Karasuno, he was seen crying, comforted by teammate Kai. After high school, he pursued a career as a childcare professional, confirmed by 2021. At a gathering with former Nekoma teammates at Kenma Kozume's home, he expressed interest in visiting Russia, referencing former teammate Yaku's residence. His playing statistics highlight strengths in power (4/5), stamina (5/5), and speed (5/5), with technique and game sense lower (1/5 each). Teammate Kenma acknowledged his agility as the best on the team, forming the basis for specialized strategies built around his mobility. His role evolved from starting middle blocker to situational wing spiker, with adaptability and a team-oriented mindset remaining consistent throughout his high school career.
