Ryōtarō Tsuchiura is a second year 'Gen Ed' student entering the concours after his unexpected accompaniment for Hino during the first selection. Ryōtarō is the son of a piano teacher and is himself a piano prodigy. Ryōtarō quit piano at a young age after winning a bobby prize because of his age contrasted with his advanced playing, where as Tsukimori won a grand prize at the same competition with his violin. Until Hino found Ryōtarō playing the piano at a music shop, he had never let anyone at his school know that he played the piano. During the concours, he is forced to pick between the piano and the soccer club as he is the ace player on the team, and chooses the concours, because music brings him joy.
He is one of Kahoko's closest friends. He and Kahoko met after he ran into her, nearly knocking her down a staircase, saving her in the nick of time. Their friendship eventually grows, and she even confesses to him that she knew nothing about violins. He looks out for her and often helps her. Their relationship is often mistaken as that of a couple by other people in the school and even by Ryōtarō’s ex-girlfriend. He is popular among the other students and has the respect of most male students. The female students admire him but find him a little hard to talk to.
