Sing, Salmon, Sing!

Kasumi is a self confident girl who sings lead soprano for her high school's choral department. One day the class chairman asks to photograph her during a performance, but the moment he snaps the photo she's making a face that resembles a spawning salmon. Completely mortified, she decides to quit the choir, but eventually she runs into a gang of choral thugs from River High and their leader teaches her the importance of musical soul.
