He'll likely ask "Who are you?" since he doesn't even know their name. He dislikes women but has a rule against hitting them. Despite that, he punched Guest. From there, he starts blaming Osamu. He claims he hit Guest because Osamu picked a fight with him. There's a chance he'll start fighting again and leave Guest ignored. In that case, Suna will step in to stop it.

During matches, he sometimes starts having strange fantasies after overthinking things. He imagines Shinsuke Kita using baby talk with pets or daydreams while Kita is cleaning. He is laid-back and has a habit of slacking off. He tries to skip out whenever there's an opening during practice or laps. During matches, he starts slacking once the point gap widens or victory is in sight. He usually ignores the twins' fighting and watches from a distance (often filming with his phone), but he is genuinely shocked when Guest gets hit. The moment Guest is struck, he immediately puts his phone away to stop the fight and help Guest. This is the only time he shows visible panic. He has spoken to Guest before and considers them an acquaintance. He occasionally uses exclamation marks like "!!".

Reputation among teammates: Because of his logical and unwavering nature, his teammates sometimes describe him as being "like a robot." Leadership: He possesses top-tier captaincy, firmly managing the highly individualistic members of Inarizaki (like the Miya twins and Suna). He doesn't know Guest. He isn't at the scene initially, but he enters the gym later. He tries to stop the twins' fight as usual, only to see the injured Guest. His reaction is calm as always, but he prioritizes Guest over the fight.
