Players (All of second year)
Chikara Ennoshita: He is auctioneer with the number six, he defend very well. He start playing instead of Asahi, who was no in the team. In my opinion he could be the next captain. (The one in the middle).
Hishahi Kinoshita: He is auctioneer and wear the number 7. In the anime, he didn't play any time so we don't know all of his habilities. (The one at the left).
Kazuhito Narita: He is middle blocker and he use the number 8. Narita play one time in the serie vs Shiratorizawa, because of the injury of Tsukishima. (The one at the right).
Management
Ittetsu Takeda: The assistant teacher. He knows almost nothing about volleyball but makes an effort to learn. He is usually quite insistent to get matches or anything else from the team. His speeches are very motivating, but they still need to be like Daichi's.
Kiyoko Shimizu: The main manager of the team, the players treat her like a goddess (especially Ryû and Noya). He goes to third and worries about the club. Before the first game, he was in charge of getting the uniforms and before the tournament, of finding and hanging the cheer banner: Fly!
Yatchi Hitoka: She goes to first grade and she became a manager to show her mother that she was good for something. She is good at designing posters so when there is a trip or an important game she makes sure that everyone knows about it. Hitoka also helps Hinata and Kageyama study.
Trainer
Keishin Ukai: The grandson of the previous trainer Ukai. Keishin can be very competitive, which is why he decided to become a coach from the beginning, since he wanted to beat Nekoma in the practice match. He continued training after that as Nekoma's trainers challenged him to another battle.
Followers
Yusuke Takinoue: He is a member of the Neighborhood Association who constantly attends official Karasuno matches. He was a Karasuno player along with Shimada and Keishin. He was a regular player on the team and his jersey number was 9. Now he works at a store called Takinoue Electronics.
Makoto Shimada: He is an attacker for the Neighborhood Association team and Yamaguchi's mentor. Shimada is a bit immature at times, as shown when he cheers up after landing a floating jump serve that opponents don't get. Despite this, he has a mentoring personality and is a good teacher; when Yamaguchi missed his floating jump serve in a match, Shimada comforted him and helped him recover.
Saeko Tanaka: She is Ryūnosuke's older sister, and was a companion of the famous little giant. Like her brother, she is loud and self-assured. One important thing that Saeko says is: "there are some flowers you only see when you take detours.
Akiteru Tsukishima:He is the older brother of Kei Tsukishima and a former student of Karasuno High School. Akiteru is kind, cheerful, and friendly. However, he seems unwilling to burden those he cares about with his own burdens or problems, dismissing him nonchalantly, only expressing his frustration or sadness when his back is turned. In a moment, it had reached a boiling point. Despite this, he is very determined and does not give up easily. He doesn't like to disappoint people, especially himself.
