“You’re the only one that sees me. Please, lend me your body.” “ECHOLL” a band that disbanded right before its major debut. One day, a year later, Souta, a university student appears in front of Yamaken, Shigeta, and Mori who are ex-members of the band. Souta steps into our everyday lives and encourages us to reform the band. Having a voice that fascinates everyone, and even though he is pushy, there is something about him that you just cannot get mad at. And the members start to feel moved by this. However, the identity of Souta was in fact Aki, the vocalist who died a year before!
