Kirari is the vocalist of the band.
She meets Shikanosuke when she begins working at the restaurant where he works. Her family is very poor, so she works mornings and evenings to make ends meet. However, her cheerful, spontaneous attitude normally masks this hardship. Her disheveled hair and her bright smile are her trademark features.

Sarina is the guitarist.
She comes from a wealthy family who funds the academy. Because of her weak constitution and her grandfather’s strict upbringing, she has very few friends. As a refined young lady, her behavior is graceful and she possesses a calm demeanor, but her will is strong. She is very good friends with Kirari and considers her irreplaceable.

Chie is Shikanosuke’s childhood friend. She plays the drums.
She is a year older than Shikanosuke, but for family reasons she had to repeat a grade. She is also the president of the Second Literature Club, which Shikanosuke and Sarina are part of. Possibly because of what she has went through, Chie is mature, thoughtful, and acts as the voice of reason for the band. However, she also keeps a tight leash on herself, disguising her laid-back and timid nature.

Shikanosuke plays the bass.
Although he had no interest whatsoever in the band, he got caught up in the string of events and wound up a member. He used to be a member of the Tennis club, but he was forced to withdraw for various reasons. At the same time, he was dumped by his girlfriend and now lives a dejected life.
