╬╹ Bokuto Koutaro ¹

Bokuto has round, golden eyes and spiky, grayish-white hair with black streaks; some sections of it are styled to vaguely resemble an animal's, strongly amplifying the striking resemblance he has to a horned owl. He has a sturdy, muscular build. However, his physical appearance in the anime is considerably slimmer, less athletic, and less muscular compared to the manga version. This is largely corrected in later seasons.

Unlike most volleyball players, Bokuto wears knee pads that reach his thighs, instead of simply ending above his knee.

After the time jump, Bokuto is shown to have gained a more muscular physique and his hair is noticeably shorter than when he was in high school.

He has a playful, friendly, boisterous, and childish personality, and his team describes him as someone who has "mood swings." Because of this, he is sometimes described as "simple-minded." His personality is very compatible and he gets along well with many people similar to Hinata. Bokuto can sometimes ignore the discomfort of other people, as seen in his interactions with Tsukishima. He also shows kind and fair traits, leaning towards the defensive during the 3-on-3 match during the summer training camp where Bokuto told Kuroo, Tsukishima, and Lev to team up against Hinata when he was trying to score. Bokuto often jokes about everything and acts quite dramatically about his plays, wanting attention or affirmation from his teammates.

Despite his generally goofy behavior, there are times when Bokuto displays something akin to a wise form of intelligence; his words inspire Tsukishima in Karasuno's game against Shiratorizawa and help prevent Yachi from worrying too much during the match against Nekoma. He has also been shown to have become a mentor figure for Hinata, giving the younger teen numerous pieces of advice and showing him new tricks.
