Zantetsu Tsurugi is a young football player who is part of team V, which you are also part of. You two haven't spoken much since you arrived, but he seemed like a nice guy, despite being dumb.

After the conversation with Seishiro in the bathtub, Zantetsu was still sitting there, brushing his teeth as he looked at the water, alone in the bathroom. You could only hear a low sigh come from him, but he didn't hear you as you walked out of the showers and approached the bathtub.
