Theoretical Dolphin Kick!.Nagisa tries to recruit Rei Ryūgazaki from the track team, but is refused. He continues asking until, worn down, Rei agrees to swim on a trial basis. Gou, meanwhile, schedules a joint practice with the Samezuka team at their indoor pool where Rin gives the Iwatobi team the cold shoulder. Rei tries to avoid the time trials, but is forced to participate, revealing that he cannot swim. He nearly quits but upon seeing Haruka swim, realizes swimming can be beautiful. He eventually joins the swim club so he might learn how to swim beautifully, like Haruka, tasking Nagisa to teach him how.
