Miya Osamu

He has a large constitution and is very similar in appearance to his brother, which shows that they are likely to be identical twins. Osamu's hair is dyed gray and his bangs turned to his left side
is a former student of Inarizaki High School. His twin brother Atsumu Miya also study and play in the same high school. His position in high school is a receiving tip.
Osamu seems to be the quietest of the Miya twins with a relaxed and inexpressive personality. Despite his external behavior, Osamu is highly competitive and heats up even if it is not obvious on the surface. However, with enough provocation, he gets angry and becomes physical. In that state, he abandons his filter and begins to vomit blasphemies. So far, his brother is the only person who made him feel so emotional. Osamu has also shown a great passion for food. He often thinks about it in the middle of a game and is distracted by the smell. It seems that he can't choose 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 leave volleyball to devote himself to a food-related occupation, that's how he ended up establishing Onigiri Miya. It has been shown that he has a sense of humor, especially with respect to Atsumu, whom Osamu makes fun of every time he makes a mistake.
