Last name: miya Setter. Unlike his twin brother, Osamu, his hair is flipped to the right side and dyed his hair blonde. Atsumu's eyebrows are dark brown. Outwardly, Atsumu appears to be a carefree, confident person who's usually seen with a lazy smile on his face, though he enjoys provoking people and giving offhand compliments. He can be quite condescending, and somewhat selfish at times. Osamu has described him as someone who doesn't listen to others, doesn't return what he borrows, and lies habitually.

Last name: Miya Opposite hitter. Osamu dyed his hair grey. Opposite of his twin brother, Atsumu, Osamu keeps his hair fringe combed to the left side of his face. He has grey eyes with hooded eyelids. Osamu appears to be the calmer of the Miya twins with a laid back and deadpan personality. Despite his outward demeanor, Osamu is highly competitive and becomes heated even if it isn't obvious on the surface. However, with enough provocation, he gets angry and physical. In that state, he abandons his filter and begins spewing profanity. So far, his brother is the only person to have ever made him get this emotional. Osamu is also shown to have a large passion for food. He thinks about it often in the middle of a match and would get distracted by the smell of it.

Last name: Ojiro Wing spiker. Aran has a dark-brown clean-cut and thick eyebrows. He's fairly tall and has a muscular, athletic build. His eyes are almond shaped and have foxlike pupils. Aran is shown to be a mature, third-year student. Despite his mature appearance, Aran is often stuck dealing with his teammates' antics and, as such, is roped into playing a "tsukkomi"—straight man—like in mansai comedy routines, as he reacts to whoever is acting as the "boke," or funny man; he is always quick to react to nonsensical things his teammates say with comebacks, such as "What does that even mean?!"

Last name: Kita Captain and defense specialist. Kita is of average height with an athletic build. He has dull brown eyes and thin eyebrows. His hair is short and light gray with black tips at the ends. His fringe is parted in the middle of his forehead, with one clump of hair hanging down in the middle just above his eyes. Kita has a very blunt way of speaking, similar to Ushijima, where he doesn't sugarcoat his words when voicing his opinion. Because of this, his teammates are often afraid to be on the receiving end of Kita's cold logic. Kita has a very mature way of thinking, saying that he tends to agree more with adults than his underclassmen, and goes as far as to have a logical reason for feeling happy and has stated that he does not understand the reason for being nervous.
