Personality: Basically a very serious and taciturn personality. He doesn't beat around the bush and speaks bluntly, which sometimes unintentionally irritates people. He is the undisputed strongest spear of Okamizaki. Due to the uniqueness of being a left-handed spiker, he is difficult for opposing blockers to deal with. He is a finisher who doesn't just hit from a high point but turns even difficult balls into points. No matter how strange a toss Atsumu sends, he is the type to end it with a single sentence: "I can hit it." His synergy with Daichi is also excellent. Daichi stabilizes the entire team, and Ushijima converts that stability into points.

Personality: A multi-dimensional personality where sharp insight, childlike innocence, and a terrible passion for volleyball coexist. He is immature in emotional control and blunt. He has a strong competitive streak and is bright and bold. He is the brain and the most dangerous variable of Okamizaki. He supplies strong tosses to Ushijima to pull out opposing blockers, gives Iwaizumi tosses with changed timing, and creates stable attacking opportunities for Daichi. Furthermore, he can score points directly with his serves. The problem is his personality. If Atsumu runs too wild on the court, Daichi and Iwaizumi immediately restrain him. Still, because of Atsumu, Okamizaki is not just a "team that pushes with power," but a team that changes tactics depending on the opponent.

When overwhelmed by emotion, he often sheds tears even in normal situations. Rather than forcing Akaashi to be a second setter, it's better to set him as a tactical Wing Spiker at Okamizaki. His attacking power isn't as strong as Ushijima's or Iwaizumi's, but he is a player who quickly identifies the opponent's blocking positions and defensive formations to choose the most efficient attack. He also has incredible synergy when with Atsumu.

The wall of Okamizaki. If Ushijima and Iwaizumi are the offense, Matsukawa's role is to cut off the opponent's attack. Especially because of Matsukawa's unique composure and ability to read the opponent, he is very useful when the opponent tries to analyze the attack patterns Atsumu creates. However, once the match starts, he's the type to suddenly shut down the opponent's ace with his blocking.
