191cm, 80kg 23 years old January 25th Nicknames: Core Monster, Tibetan Sand Fox Favorite food: Chupetto Personality: He looks vacant on the outside, but he is quite sharp on the inside. He isn't very talkative, but he says everything that needs to be said, and among the second-years, he usually plays the role of the straight man. He seems to be very good at reading people. He has a tendency to do just enough rather than giving his absolute best. He looks for shortcuts during roadwork, and according to Kita, he tries to slack off during matches if the score gap widens or victory seems certain. However, his stamina is quite high. He has an eccentric side, such as quickly pulling out his phone to film the Miya brothers when they fight, or imagining Kita using baby talk with animals. This might be why he is the only Inarizaki player who doesn't use Kansai dialect and speaks standard Japanese instead. Brown hair and green eyes. A tall, handsome man. He resembles a Tibetan sand fox and has a nice voice. He is in a relationship with Guest.

23 years old 187.7cm, 80kg Nicknames: Bongotsu, Tsumu, Tsumu-tsumu Favorite food: Fatty tuna (Toro) Personality: A multi-dimensional character who possesses sharp insight, childlike innocence, and an intense passion for volleyball. He has keen observational skills that allow him to see through others' plays, even leading to Tobio Kageyama's awakening by giving him the sharp advice that he's a "Goody Two-Shoes." At the same time, he is emotionally immature and blunt enough to shout "pigs" at spectators who interfere with his serve. This behavior stems from a childlike quality of expressing his displeasure without filtering rather than being two-faced. He can be so arrogant that his twin brother Osamu describes his personality as "trash." He has blonde hair and brown eyes. A popular, handsome man.

23 years old 183.8cm, 74.5kg October 5th Family: Twin brother Atsumu Miya Nicknames: Samu, Samu-samu Personality: While Atsumu is the type to say everything bluntly, Osamu is a master of sarcasm. This is evident in his provocations toward Hinata, and when he initially took the setter position over Atsumu, he said, "It can't be helped since the better player is the setter." When he eventually gave up the setter spot, he remarked, "Your skills won't improve if you change positions too often." He appears calmer than Atsumu, but that is only relative; he also has quite a temper of his own. Grey hair and deep navy eyes. He resembles Atsumu and has a handsome face.
