Mitobe has medium-length black hair that is parted to the sides, but with one strand of hair between his eyes. He also has very thick eyebrows. One of his distinctive features is that he always has his mouth closed, even when playing, and never speaks. He wears the Seirin jersey with the number 8. He is also one of the tallest members of the club.
Mitobe is just as determined to win as the other players at Seirin, but unlike the others, he doesn't show his feelings that often. Most people know him as a quiet, hard worker. According to Riko, no one has ever heard Mitobe talk.
Mitobe has a large family and is in charge of making breakfast every morning, thus he is skilled in household chores and cooking. He is naturally caring and often worries about the well-being of his teammates, especially the underclassmen and Koga, whom he has known the longest. Somehow, despite the fact that he is mute, most people understand what he is thinking and can even hold a conversation with him, especially Koganei, who seems to understand Mitobe perfectly. He also seems to be somewhat of a pushover, since both Koga and Hyūga can boss him around easily.
Mitobe joined the Seirin team together with Koga. Koga reveals that Mitobe had been playing since Junior High school while he himself was a beginner. Koga claims that he started playing basketball because he watched Mitobe and thought it looked fun. Later, Koga also revealed that Mitobe was a power forward in Junior High School. 
When the team shouted their resolve on the roof to convince Riko, Koga yelled Mitobe's name and class for him and Mitobe was shown looking relieved afterwards.
As a regular player then, he played in Seirin's matches in the Interhigh preliminaries, until they lost in the final league. After Kiyoshi's injury, he changed positions from a PF to a Center.
He is first seen, together with the other regular members, distributing flyers and recruiting for the basketball team. (Koga encourages him to shout, to no avail).
Seirin vs Kaijō
During Seirin's practice match against Kaijō High, Riko described Mitobe as "the hardworking and unsung hero, with the voice no one has ever heard."
Mitobe is one of the tallest of the team, so he block shots and plays low and high post. In the match against Seihō High, he also showed that he can dunk. He has been playing basketball since Junior High school.
Mitobe is a veteran when it comes to defense, especially guarding players bigger than him, through his pressure defense. He does this, not by blocking their shot, but by not letting them do what they want to do; in the process the opponent was forced to miss. He taught this method to Kagami, who used it against Dad and Okamura in their matches.
Just as the other second years of Seirin, Mitobe has spent the last year training on one particular technique: His hook shot. Using his body to position between his defender and the ball, he shoot with his free hand (its trajectory looking like a "hook"), that is almost impossible to block. Theoretically, you can jump off both feet (jump hook), one foot (hook shot/sky hook/baby hook), or sweeping the shot while having the body gliding across the court (sweeping hook/sky hook/running baby hook).
