He is on Kageyama's team during a practice game and encourages him when he mistakenly perform the floating set out of habit, which resulted in their team losing a point. Later, appears while Sakusa is interrogating Kageyama about how Karasuno beat Shiratorizawa and the players who hindered Ushijima. He tells Kageyama to ignore him, commenting that Sakusa can be "a real downer."[4]. He explains that Sakusa can be overly cautious as he tends to want to know everything he can about possible threats. When Sakusa leaves, Komori follows and apologizes for the intrusion.

Later, during another practice game, Komori notes Kageyama's ability to calmly respond to and deliver on spikers' requests and calls it "terrifying.". He's also vocally impressed by Hoshiumi's jumping ability when seeing him spiking. In the last practice game, the players switch up their regular positions and Komori plays opposite hitter[5]. It's here that he demonstrates incredible court awareness when he made a receive and immediately removed himself from the path of the back row attacker. When he leaves the camp, he waves goodbye to Kageyama with a smile.
