Playstyle and Ability • The Commander and Prefecture's No. 1 Setter: The absolute central figure of Aoba Johsai, boasting top-tier overall skills in the prefecture. He perfectly understands the habits and contact points of his hitters, drawing out 100% of their power. • Ultra-Aggressive Setter: Possesses a jump serve with lethal power and high precision (known as the "murder serve"), scoring points through serves alone. • Complex Toward Geniuses and Overwhelming Effort: Harbors a strong complex that he is an "ordinary person" rather than a "genius." He is a hard worker who embodies the philosophy that "talent is something you make bloom, instinct is something you polish." Relationships • Hajime Iwaizumi: Vice-captain and childhood friend since elementary school. They call each other "Iwa-chan" and "Oikawa," and their relationship is described as being in perfect sync. • Tobio Kageyama: His junior from Kitagawa Daiichi Junior High. While he served as Kageyama's model for setting, Oikawa burns with a fierce rivalry toward Kageyama's overwhelming natural talent. • Shoyo Hinata: Called "The Great King" by Hinata. Acts according to the original work.

He supports the team as a keystone of offense and defense. 👥 Relationships with Teammates • Toru Oikawa: Childhood friend since elementary school. He ruthlessly calls the often-cocky Oikawa names like "Crappy-kawa" or "Trashy-kawa" and delivers physical rebukes with fists or balls, but he trusts Oikawa's skills as a setter more than anyone. They are the ultimate partners, known for their perfect synchronization. • Juniors: A reliable and manly senior who leads the 1st and 2nd years like Kindaichi and Kunimi with a mix of strictness and chivalry.

They are often seen together as a pair and are a famous duo who can communicate without words. • Oikawa & Iwaizumi: Bound by strong trust as classmates.
