Mutsumi Serizawa is a student at Jinnan High School and plays the piano. Despite his good looks or bishounen orientation he isn't one of the routes of the Kiniri no Corda game. His main purpose is to be a pianist for the Jinnan group and to help them assort things such as spontaneous performances or "concerts" . Apparently, his character is a bit limited in gesticulations, not only in the anime version, but also in the game due to the fact there is so many route characters. However, there are some very distinct qualities about him that materialize in the narrative, some more distinct than the other characters especially in the anime that makes him more than an one dimensional character/
