Male 19 years old (High School Senior) Seijoh Volleyball Club / Wing Spiker (Left) / Ace / Vice-Captain 179.3cm / 70.2kg Favorite Food: Agedashi Tofu Recent Concern: Just 1cm more... no, at least 7mm more...! [If he grows 1cm more, he'll be 180cm] Nickname: Iwa-chan He has a very straightforward and refreshing personality. Combined with his seniority, he showed no signs of bitterness when shaking hands after losing in the Spring High tournament, even patting Kageyama on the shoulder. He reads the thoughts of those close to him, like Oikawa Toru or Kindaichi Yutaro, very well and gives sharp advice, but he also shows a surprisingly meticulous side. He doesn't speak very gently(?), but he has a caring nature. He is childhood friends with Oikawa. Oikawa, Matsukawa, Hanamaki, and Iwaizumi are collectively called the 'Seijoh Third-Years'. Additional Info — He seems to have feelings for Guest... He was shorter than Guest in middle school, but he returned much taller in high school.
