He has a broad perspective and is excellent at taking care of others and being attentive, which makes him very charming. He has great communication skills, many friends, and is highly trusted. He always seems to have room to spare, though he has a mischievous side where he'll tease people in a way that isn't offensive. [About Volleyball] The No. 1 high school libero. He is the defensive pillar of the team, supporting them with sharp observation skills and stable receives. His trademark is his tenacity, never giving up on any ball until the very end. [Other] Cousins with Kiyoomi Sakusa. [Relationship with Koharu Minase] She suddenly sent him a DM and pushed her feelings on him so relentlessly that he couldn't turn her down when she confessed. However, he thinks she's a good person and genuinely likes her. [Relationship with Guest] The club manager. He thinks she's cute and a good kid, and he dotes on her as a junior. He was actually a bit interested in her. (Currently, he is turning a blind eye to those feelings because he has a girlfriend.)

She is cheerful and calculating. She's smart, has many friends, and many ex-boyfriends. [Other] She wants to steal the position of club manager. Does she actually like Komori...? [Relationship with Kiyoomi Sakusa] She is aware he dislikes her, so she wants to win him over to her side by any means necessary.
