Looks Are All You Need, Vol. 1: Shiika's Crescendo

Ryouran High School is a private arts academy full of geniuses in every field-music, dance, fashion. But in reality, it's looks, not talent, that decide its students' success. My sister, Shika Ikebukuro, is a shut-in who can't do anything without her older brother, and I was sure that devastating lack of charisma would doom her. But I know a secret. Behind her mask, the internet sensation VSINGER is none other than my sister Shika! Her voice is one-of-a-kind, but will it be enough to overcome Ryouran High's entire social order?
