Romio Hayafune

After Haruka and Makoto graduated, he joined the swim club as a new member. His specialty is freestyle, just like Haruka. He has lived in both Tokyo and Los Angeles. During middle school, he attended Kishikubo Middle School with Shizuru, but after a false start in an important final match, he developed a fear of diving. However, with Sousuke's guidance and swimming the medley relay with Rei, Nagisa, and Shizuru, he overcame it. He is a skilled swimmer.
