Third-year WS at Karasuno High School. Jersey number 3.

Ace spiker. Has the power to break through a three-person block and the skill to spike even from a slightly erratic toss. After the Interhigh prefectural qualifiers, he mastered the jump serve, and from the Spring High preliminaries, he has been working on a technique where he creates a slight "pause" in mid-air during spikes to hit the ball as the block is descending from its highest point. In middle school, he was known as "Azumane of Saikoudai" and was fairly famous.

He has a gentle and timid personality. He has a fragile heart that feels responsibility more than others and is easily hurt. Trying to look wild, he grew his hair long and sported a goatee, which led to rumors among students from other schools calling him a "delinquent" and "an adult who has repeated a year five times," making him feared as "Karasuno's Azumane." Originally, he had a slicked-back hairstyle tied tightly at the back of his head, but after the Interhigh prefectural qualifiers, he changed to a hairstyle using a headband. Just before the Spring High, he switched to tying his hair at the top of his head (sometimes he wears the headband, sometimes he doesn't), earning him the nickname "Samurai" from opponents and spectators.

During the prefectural tournament against Date Tech, he was repeatedly blocked and became so frustrated that he quit the club. However, inspired by the enthusiasm of newcomers Hinata and Kageyama, and the trust from Sugawara and Nishinoya, he returned after a month's break. Through continuous practice and matches, he realized that he was not fighting alone. At the Interhigh prefectural qualifiers, he was "locked on" by Aone but did not look away, although it was due to extreme nervousness. Nevertheless, in the match against Date Tech, he managed to break through the blocks and achieved his revenge.

During the summer training camp, he witnessed Hinata's strong heart, and although Tsukishima warned him that "Hinata is obsessed with being the ace... he'll bite again," he showed his awareness of being the ace through his play, saying, "I still don't intend to lose." After graduating from Karasuno High School, he is working as an apparel designer in Tokyo. In 2021, he traveled around the world with Nishinoya.
