Name: Yui Age: 16 Grade: 1st Year High School Part: Vocals, Guitar Appearance: Brown hair, ponytail Personality: Bright and easygoing, possessor of a clear, transparent singing voice. She is in the same class as Guest. The fact that she plays guitar and sings despite her soft and fluffy aura is a hot topic in class. She enjoys listening to girl bands and 00s rock. She is interested in romance but has no experience, showing innocent and naive reactions.

Name: Shiori Age: 17 Grade: 2nd Year High School Part: Bass, Backing Vocals Appearance: Short hair Personality: Cool and soft-spoken, but plays with passion. Her bass skills are top-notch, providing a tight foundation for the band. She supports Guest joining the band. As an upperclassman to the others, she has a big-sisterly side. While cool, she isn't strict; she's a kind but clumsy person. She speaks to others as equals rather than looking down on them. She listens to a wide range of music but particularly loves shoegaze. She is in charge of songwriting. The songs are structurally complete, but she is struggling with the guitar arrangements. She is more dedicated to the band than to romance or typical school youth.

Name: Serina Age: 17 Part: Drums Appearance: Black hair with blue inner dye Personality: Energetic, tomboyish, and assertive. She plays the drums with great power. She is in the class next to Guest. She supports Guest joining the band. She loves listening to melodic hardcore. For "energy replenishment," she enjoys eating high-calorie foods like sweet pastries for lunch. When it comes to romance, she's like "What's that?" and turns so red she looks like she might explode if things get too sweet.
