Ukai has dyed blond hair with brown eyes and wears a headband. He has two piercings on his left ear that he removes during practices and games. He has been repeatedly told by Nekomata that he resembles his grandfather, the former Coach Ukai. In high school, Ukai had a dark brown buzzcut but otherwise looked the same.

Post-timeskip, Ukai appears to have allowed his hair to return to its natural dark color.

Ukai's behavior is fairly typical of a man in his 20s. He smokes and drinks and is willing to speak casually about alcohol to minors, using terms like "a first gulp of beer" to explain a volleyball tactic to Karasuno. He is quite competitive, agreeing to coach Karasuno only so he could beat Nekoma in the practice match and then staying on because of challenges he made with Nekomata. Ukai appears lazy and cranky, spending most of his time at work reading a newspaper with his legs on the counter or yelling at people for being too loud.

However, he's shown to have strong coaching skills and is a hardworking individual. Ukai chose to change his work schedule to a much earlier time in the morning to make up for the time he takes off to coach Karasuno. It's also been noted that in high school and college, Ukai excelled in mentoring underclassmen and had strong analysis skills of opponents. He also said that he wasn't very good at studies to Hinata when he asked Ukai to help him study. While at work, Ukai would yell at high school students and remark that he's out of a product without bothering to check, but he does have a kind side as he gave Tanaka, Kageyama, and Hinata free energy bars.

Keishin Ukai is Ikkei Ukai's grandson. He is an alumnus of Karasuno High and was a setter on the Boys' Volleyball Club eight years ago, having worn the number 2, but did not play in any games until the official setter was unable to and he was given the spot. He continued playing volleyball in college and after graduating, having joined the Neighborhood Association team.[2] He works at Sakanoshita Market, a family business that is passed down his mother's side.

Ukai used to be a setter, but he was not a regular while in high school. This implies that he isn't an extraordinarily skilled player, a trait that he is often teased for by his grandfather[18]. As a coach, Ukai has very high abilities in analysis and tactics. He goes the extra distance to collect as much data on their opponents as possible in order to formulate an effective plan to counteract them. While he has the knowledge to help the team improve as a whole or individually, he himself admits that he is not always the best choice to demonstrate and will suggest others who would be better to learn from; best seen when he told Tsukishima about timing during blocks and suggested the first-year seek help from Kuroo since he wouldn't be able to show Tsukishima how to do this properly.
