Yui Michimiya (Japanese:
She has short, dark brown hair. Her round eyes are a lighter shade of brown.
Michimiya is shown to be a very active person, always smiling and cracking jokes. She is a very determined person, who cares a lot for her team, giving them motivational speeches and always tries to stay composed in front of them; she only cries when she's away from her teammates. However, she herself had stated that she isn't strict enough.
Around Daichi though she can become flustered and clumsy, repeating words to try and find the right thing to say.
She went to Izumitate Middle School with Daichi Sawamura and Hayato Ikejiri. She is currently a third year in Karasuno High and was a wing spiker and the captain on the girls' volleyball team before retirement.
Before the Interhigh begins, Michimiya approaches Daichi in the hallway and hands him the schedule for the pep rally. While they are talking, Yui accidentally lets it slip that she thinks her team will lose quickly and Daichi responds with encouraging words that Michimiya takes into heart.
Before the first match begins in the Interhigh, Michimiya warms up with her team in the stadium. However, her teammates are doubtful of whether they could win or not so Michimiya motivates them with a huddle and team cheer. Soon afterwards, the first match begins but the Karasuno Girls' Team makes a lot of mistakes, and despite how hard Michimiya tries, her team loses. Michimiya then leads her team out of the gym and to the hallways where they pack up. One girl suddenly starts crying, stating that it's her fault the team lost, but Michimiya cheers her up. Michimiya soon leaves the room and as soon as she's out of sight of her teammates, she bursts into tears over her loss.
Sometime afterwards, Michimiya retires from the team and a new captain's elected.
Tokyo Expedition Arc
Michimiya's in her classroom when someone tells her that Daichi wants to see her. She blushes heavily while rushing outside excitedly. Daichi asks her if he can borrow the girls' gym since they're done practising, and Michimiya tells him to wait for her to ask for permission. In the meantime, she asks him why he needs the gym and he replies sheepishly that some of the players want to practice separately.
Spring High Preliminary Arc
Michimiya approaches Daichi outside the volleyball stadium before the Karasuno vs Shiratorizawa match begins and nervously gives him a charm, explaining that it isn't just for him but for the entire team. Daichi accepts it happily and Michimiya runs back to her friend, her face completely red. Her friend states simply that she's shocked Michimiya even managed to give the charm to Daichi.
Michimiya finds a spot in the bleachers with her friend and cheers on Karasuno. She cries at the end when Karasuno wins the match and proceeds to Nationals.
