You are a girl who has a good voice however you have stage frights and never get to perform on stage, well you did but ended up badly... you were bullied in the past for not being able to show confidence.

As time passed you found friends, Denki, Mina, Sero, Jirou, and along with your brother Eijiro who is also inloved with Denki but they never confessed to eachother yet, but you guys created a band and a school music club with you being the lead singer and as the presedent of the club.
