Ukai has dyed blond hair and wears a head-band. He has two piercings on his left ear. He has been told by Nekomata that he resembles his grandfather, the former Coach Ukai. In his youth, Ukai had a dark brown buzzcut, but otherwise looked the same.
Ukai's behaviour 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. 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 popsicles.
Keishin Ukai is Coach Ukai 's grandson. He is an alumnus of Karasuno High and was a setter on the Boys' Volleyball Club eight years ago, having the number 2. He continued playing volleyball in college and after graduating, he works at Sakanoshita Store, a family business he inherited from his mother's side.
Karasuno High Team Formation ArcEdit
Ukai makes several background appearances in the beginning as a cranky clerk at Sakanoshita Store. He later receives calls from Takeda, who persistently requests that he becomes the new coach for Karasuno Boys' Volleyball Team. When Takeda confronts him at the store, Ukai asks if it's just the "Ukai" name that Takeda wants and after Takeda confirms it, Ukai seems to think over it. Despite that, he rejects Takeda anyway, claiming that he doesn't want to babysit high school boys. He later reveals that he doesn't want to go back to Karasuno because of the nostalgia it invokes in him, but he's eventually convinced when Takeda reveals that he wants Ukai to coach for the upcoming practice match against Nekoma. Ukai then schedules a practice match against the Karasuno Neighbourhood Association to test the players' skills and figure out their weaknesses.
Tokyo Expedition ArcEdit
Spring High Preliminary ArcEdit
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.  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.
Ikkei is Ukai's grandfather and Karasuno's former volleyball coach. Initially, Ukai claims that he isn't the same as his grandfather and couldn't coach, but he later disproves that with his sharp mentoring skills. The two of them have a rough relationship with Ikkei flipping Ukai occasionally and arm wrestling with him. Ukai has a lot of respect for his grandfather, going to him for advice when he needs help with his own players. Ikkei comes to watch Karasuno's matches in the Spring High and is teased by spectators for watching his "dear grandson's" team, though Ikkei doesn't deny it.
Both Ukai and Takeda care deeply for the Karasuno volleyball team. They often commentate with each other on matches Karasuno participates in and have a strong sense of respect for each other. Initially, Ukai is annoyed by Takeda's persistent attempts to get him onto the team, but later expresses his gratitude for Takeda's efforts. It's shown that even Ukai would cower if Takeda's angry.
He has great respect for his alma mater, but he considers the first and second years as the "hyperactive ones and simpletons". Despite that, Ukai cares a lot about his players, giving them advice on how to play and what to eat.
They were friends in high school because of their similar situations of being third years, but not starting members because of an underclassman. Thus, they dubbed themselves the "Benchwarmers Club". However, it's implied that they haven't seen each other since then. When they meet again in the Nekoma practice match, they tease each other for their appearances and reconnect.
