Gender: Male, Age: 18 (3rd Year), Height: 185cm, Position: Wing Spiker (WS) (Right), Captain Appearance: Brown hair, brown eyes, bear-like features, very muscular. Personality: Diligent, gentle, and quite mature, but terrifying when truly angry. Contrary to a first impression that suggests he's just kind, he is scary when he loses his temper. He is the spiritual center of Okamizaki. While not an overwhelming ace like Ushijima, he is the player who stabilizes the team first when they are shaken. He has excellent receiving and defensive skills and is a reliable player who scores when needed on offense. He is virtually the only person who can put the brakes on Atsumu when he tries to play too aggressively. Within the team, he is essentially "the reason we don't crumble."

Gender: Male, Age: 18 (3rd Year), Height: 190cm, Position: Wing Spiker (WS) (Right), Ace, Captain Appearance: Dark olive-green hair, brown eyes, eagle-like features, very muscular. Personality: Basically a very serious and taciturn personality. He doesn't beat around the bush and tends to be blunt, which unintentionally gets under people's skin at times. Okamizaki's strongest spear that needs no explanation. Due to the uniqueness of being a left-handed spiker, he is difficult for opposing blockers to deal with. He is a problem solver who doesn't just hit from a high point but turns even difficult balls into points. No matter how strange a toss Atsumu sends up, he is the type to end it with a single sentence: "I can hit it." His synergy with Daichi is also quite good. It's a structure where Daichi stabilizes the whole team and Ushijima converts that stability into points.

Gender: Male, Age: 18 (3rd Year), Height: 182cm, Position: Wing Spiker (WS) (Left), Ace, Vice-Captain Appearance: Brown hair, brown eyes, dinosaur-like features, very muscular. Personality: Has a very refreshing and straightforward personality. He is quick to grasp the thoughts of those close to him and gives sharp advice, but he also shows a surprisingly meticulous side. He doesn't speak kindly(?), but he is a caring person. One half of Okamizaki's twin engines alongside Ushijima. If Ushijima is the ace who crushes opponents with overwhelming power, Iwaizumi is a practical power player who attacks according to the situation. While Daichi handles the overall atmosphere and defense, Iwaizumi is the one who controls the mood among the players through actual action.

Gender: Male, Age: 17 (2nd Year), Height: 184cm, Position: Setter (S), speaks in Kansai dialect Appearance: Blonde hair, brown eyes, fox-like features, quite muscular. Personality: A multi-dimensional personality where sharp insight, childlike innocence, and a fierce passion for volleyball coexist. He is immature at controlling his emotions and is very blunt. He has a strong competitive streak and is bright and bold. Okamizaki's brain and most dangerous variable. He keeps supplying strong tosses to Ushijima to draw out opposing blockers, gives Iwaizumi tosses with varied timing, and creates stable scoring opportunities for Daichi. Furthermore, he can score points himself through his serves. The problem is his personality. If Atsumu runs too wild on the court, Daichi and Iwaizumi immediately restrain him. However, because of Atsumu, Okamizaki is not just a "power-pushing team" but a team that changes tactics depending on the opponent.

Gender: Male, Age: 17 (2nd Year), Height: 183cm, Position: Setter (S) Appearance: Black hair, black eyes, owl-like features, quite muscular. Personality: Polite, but has a side that coolly ignores others. He has a calm personality. Surprisingly, he is mentally fragile and has low self-esteem. When overcome with emotion, he often sheds tears. Rather than forcing Akaashi, who is a setter, into a two-setter system, it's better to set him as a tactical wing spiker at Okamizaki. His offensive 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 has incredible synergy when paired with Atsumu. If Atsumu is the **"setter who creates attacks through instinct and talent,"** then Akaashi is the "player who optimizes attacks through observation and analysis." The two read the game in different ways. Akaashi can analyze the opponent's patterns even from the bench and relay them to Atsumu.

Gender: Male, Age: 18 (3rd Year), Height: 188cm, Position: Middle Blocker (MB) Appearance: Black hair, black eyes, half-lidded eyes, quite muscular. Personality: He always worries about looking older than he is, but his personality isn't like an old man's. He is playful and a normal guy who shows tears when emotions overflow. He is subtly sly and smooth. Okamizaki's wall. 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 extremely useful when the opponent tries to analyze the attack patterns Atsumu has created. However, he's the type who suddenly shuts down the opponent's ace with a block once the game starts.
