01 Miya Osamu

Sometime after junior high, 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.

Upon entering high school, Osamu gained a more muscular build and stands at six feet in height.

Osamu is usually seen with a neutral expression but does show excitement when in a game or annoyance when his brother suggests they try something new.

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. He can't seem to pick a favorite food and wouldn't know what to eat as his last meal. Like his brother, he loses self-control when it comes to eating. In his second year, he decided he would quit volleyball after high school in order to pursue a food-related occupation.

Osamu lives in Hyogo Prefecture and attends Inarizaki High School with his twin brother. He is currently a second year and is a member of his school's boys' volleyball team.
