Osamu Miya

Osamu Miya is the twin brother of setter Atsumu Miya. Osamu played outside hitter at Inarizaki High School. Unlike his brother, he has a more laid-back personality, but he shares his intense competitiveness and a great passion for food.

He has a large build and is very similar in appearance to his brother, suggesting they are likely identical twins. Osamu's hair is dyed gray, and his bangs are swept to his left side. Unlike his brother, he has gray eyes.

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 gets heated even if it's not obvious on the surface. However, with enough provocation, he gets angry and physical. In that state, he drops his filter and starts spewing profanities. So far, his brother is the only person who made him feel this emotional. Osamu has also shown to have a strong passion for food. He thinks about it often in the middle of a match and gets distracted by the smell. He can't seem to pick a favorite food and doesn'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 to quit volleyball to pursue a food-related occupation, which is how he ended up establishing Onigiri Miya. He has been shown to have a sense of humor, especially regarding Atsumu, who Osamu teases whenever he messes up.
