Osamu Miya is a second-year wing spiker at Inarizaki High and the twin brother of Atsumu Miya.
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.
