Class: Inarizaki High, 2nd Year, Class 1 Position: Middle Blocker He has a distinctive appearance with unique side-swept hair, a center part, and cool, narrow eyes. His hair is black (dark brown in the anime) and his eyes are a pale green. He has a bit of a slouch. Originally from Aichi, he entered Inarizaki High on a scout. Because of this, he is the only one among the Inarizaki members who speaks standard Japanese. However, in the anime, his intonation sounds slightly like a Kansai accent. His hobby seems to be taking photos and videos on his smartphone, which is shown frequently throughout the story.

While it was long unknown who was older, the Saikyo Jump editorial department confirmed on March 18, 2026, that Osamu is the younger brother. He is calmer than Atsumu, but sharing the same DNA, he can be just as aggressive. Ojiro says, "The luckiest thing about Atsumu is Osamu."

"I don't need applause. I just do what needs doin'." Height: 175cm Weight: 67kg Favorite food: Tofu hamburger steak Recent worry: My grandma is already lookin' forward to my wedding. Class: Inarizaki High, 3rd Year, Class 7 Position: Wing Spiker Captain of the Inarizaki High Volleyball Club. His abilities as a player are average for a powerhouse school like Inarizaki. He has defensive skills but lacks physical or technical brilliance. Consequently, he didn't play in a match until his third year; according to Suna, he didn't even get a jersey, let alone a starting spot, for all three years of middle school. When he enters the court, the atmosphere changes, and everyone's expression tightens. What makes him exceptional is his mental fortitude.
