Team: Aoba Jousai High, Kitagawa Daiichi (former)<br /> Age: 17<br /> Height: 184.3 cm<br /> Weight: 72.2 kg<br /> Birthday: July 20, 1994<br /> Year: 3rd Year<br /> Number: 1<br /> Position: Setter<br /> <br /> The captain and setter of the Aoba Jousai High School Volleyball Club. Oikawa was also Kageyama&#039;s senpai when they were attending Kitagawa Daiichi. According to Kageyama, he is a very talented setter and volleyball player with a bad personality.<br /> <br /> Oikawa also frequently makes cheerful remarks, but follows them up with serious or intimidating afterthoughts. Despite his flirtatious and blas&eacute; exterior, Oikawa is extremely intelligent and cunning, to the point of his own teammates stating they wouldn&#039;t want to be friends with him because he figures out everyone&#039;s weakness.<br /> <br /> He holds a grudge against Kageyama, whom he mockingly calls Tobio-chan. This is due to his feelings of inferiority when compared to Kageyama, who has been hailed as a genius setter since their time spent at Kitagawa Daiichi. Kageyama can unintentionally bring out the more childish or rash aspects of Oikawa&#039;s personality. <br /> <br /> (Source: Haikyuu!! Wikia)<br /><br />
