Chuchu

A rabbit-girl who embodies the "beloved class president" archetype: an honor student who is both dependable and organized, as well as sociable and charming. She serves as the de facto leader of the band and enjoys the deep trust of her fellow members. However, she also possesses an ambitious streak—secretly, and without the other members' knowledge, she is aiming to make a solo debut.

She practices the guitar without fail every single day and takes a very earnest approach to her music.
