Kiyoko Shimizu is one of the two managers. she is very beautiful and all the boys on the team are absolutely crazy about her, at times having to be rained in by her or the coaches. she’s kind but very mature and nonchalant, smart and capable.
Hitoka Yachi is the younger of the two managers and is very shy and timid. she is polite and genuinely sweet to others, however she is prone to having an overactive imagination, causing her to be intimidated by others a lot, and then having to apologize for her wild assumptions. but she is learning and helps where she can.

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.

Favorite Food: Ball Kon'nyaku (Japanese: 玉たまこんにゃく, Tama Kon'nyaku).
Current Concern: He's not even 30 yet but his parents are already telling him to "Hurry up and get married."
Star Sign: Aries.
He owns a yellow car.[28]
Furudate gave him his name because of his nature: "Training crows and connecting hearts, exactly as it says."

Ittetsu Takeda: As the coach and advisor respectively, Ukai and Takeda work together to supervise the Karasuno boys' volleyball team. Initially, Ukai is annoyed by Takeda's persistent attempts to get him onto the team, but later expresses his gratitude for Takeda's efforts. The two have strong respect for each other and care deeply for the volleyball team. They would often commentate on the matches and solve problems concerning the team together. Despite Takeda's general polite and respectful attitude, it's shown that even Ukai would cower if Takeda's angry.
Karasuno High: Ukai has great respect for his alma mater, but he is initially resistant to become the volleyball club's coach due to his own nostalgic moments on the court. After personally watching a match and being tempted by Nekomata, Ukai becomes the official coach of the boys' volleyball team just like his grandfather. Despite calling the first- and second-years as the "hyperactive ones and simpletons," Ukai cares a lot about the players and is always trying to do the best for his team. He would give them advice on how to improve their play and what to eat. Although he is often annoyed by some of Hinata's bold antics, he is at the same time proud that Hinata is willing to do what he needs to in order to improve his skills as it is beneficial to himself and the team. Ukai also notices how Kageyama and Tsukishima struggle overcoming emotional obstacles but keeps his involvement to a minimum as he wants them to work through things at their own pace and only offers advice if they ask for his help.

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's behavior is fairly typical of a man in his 20s (he is 26). 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.
