Usuri has light-colored hair parted down the middle, thin eyebrows, and round eyes. Compared to his teammate Kiryū, his appearance gives off a more approachable feel.
To his teammates, Usuri is the encouraging player who assures that his team will do well. However when facing off other teams, Usuri is manipulative and is able to alter the opponent's conditions in game with his planning. His personality is described as awful or shady when he gets overly excited into the game. Usuri also finds pleasure in his opponents' despair when they are being overwhelmed by his team and always has a wide smile on his face.
He currently attends Mujinazaka High, located in Ōita Prefecture in the region of Kyushu.
Tokyo Nationals Arc
Usuri interrupts Kiryu’s reflection back on his conversation with Bokuto, and asks him if everything is alright. When Kiryu answers no, stressed, Usuri tries to cheer his captain up and says that it’s going to be alright either way because their team has Kiryu since he’s always the best.
Usuri starts off the match with his serve, and Konoha is easily able to bump it to Akaashi, who sets it to Onaga. However, Unnan blocks Onaga’s spike, earning Mujinazaka a point. Even though Usuri has most likely seen far greater blocks than this in the past, he still congratulates Unnan. Usuri serves again afterward, but this time it flies out of bounds, which he apologizes for.
Right after, the ball approaches Usuri and decides to send it to Kiryu, a broad smile showing on his face. After his spike easily triumph over Fukurōdani’s triple block, everyone is astounded by Kiryu, but Kenma notices Usuri and asks Kuroo whether he’s a famous setter, to which Kuroo answers that he hasn’t ever heard of him.
Later on in the match, Usuri serves, but Sarukui is able to bump it, Daichi internally commenting that he made that look easy but in truth, it took a lot of skill. The ball goes to Akaashi, but Usuri immediately realizes that he’s about to do a setter dump, which alarms Akaashi. When Akaashi is tensed, Usuri beams at this, being able to figure out how the opposing setter is thinking. He then turns to Bishin and says that everything is going perfectly, showing even more glee.
After that, Usuri figures out that Akaashi is probably a “by the book” kind of player, and all he needs to do to make him panic is make him mess up, and that if his setting becomes rushed and panicked, Fukurodani would lose and it would be Mujinazaka’s win.
However, when Usuri sets to Unnan, it’s too slow, so it lets Bokuto block the spike, which scares Usuri for the first time in the match. After this, Bokuto gets fired up to win the game and scores multiple points in a row, and Usuri is seen having a look of fear on his face. His worries soon vanish when Akaashi gets benched to have Anahori in instead.
And when Kiryu is thinking back at his teammates, he thought of Usuri and Mami’s words of motivation to him, thinking that he is blessed for having such great teammates. And that if they were going to say that about him, instead of running away, he should let it go to his head. After Bokuto yells out that he couldn’t believe that volleyball could be so tiring, Kiryu laughs scoffs, and Usuri is immediately shocked at this, calling Bokuto scary for being able to make Kiryu laugh during a game.
Near the end of the game, when Mujinazaka was a the brink of losing, Usuri tells himself that it’d be okay because Kiryu is the greatest and then attempts at doing a setter dump, which succeeds. When Kiryu congratulates him, Usuri says that his dump only succeeded because everyone was paying attention to Kiryu.
When Fukurōdani is at 24 points, it’s Usuri’s turn to serve, and Konoha is able to bump the ball to Onaga, which lets him spike the ball over to Mujinazaka’s side of the court, winning Fukurodani the match. After Mujinazaka loses, Usuri walks up to Kiryu, crying, apologizing for setting to him way too much and putting pressure on him as the ace, and says that it’s especially bad when sometimes Kiryu alone is getting overwhelmed by Mujinazaka’s opponents, but Usuri still sets the ball to him. However, Usuri then claims, louder this time, that he only sets to him because he wants to.
Kiryu then praises Usuri for being an excellent setter to him and to carry the team and to take care of their coach in the following year.
Usuri is seen watching Karasuno’s game against Kamomedai next to Kiryu after their loss.

Kiryu, who tends to struggle with shouldering others' expectation of him, does not blame Usuri for this and thinks that he's blessed to have such an amazing setter/teammate as Usuri.
Usuri gets along well with the rest of his teammates. He is openly encouraging and praises them when they make a good play. His teammates are aware of his scheming nature as a setter. Nevertheless, they trust him and go along with his plan after Usuri suggested shutting down Fukurōdani's setter in addition to the ace.
