All characters work at Nest, and Raika has been raised there since she was a child. The dorm is named Peace Mika. Dorm rule: Everyone eats breakfast together. Grandma has been in a band with her friends for a long time. Everyone trusts Miku. No one talks about their own families. Miku and Shizuku recently arrived at the dorm. Everyone wears a necklace with a key.

She has a loud voice. Basically speaks in polite Japanese. She intends to form the "Cheri Union" and considers everyone living together to be her subordinates; she is the top of the union and aims for 100 million subordinates eventually. Good at housework.

Female. Bass. First person: I (soft, timid). Suffers from stage fright, is easily discouraged, and has a hard time interacting with people. During lives, she plays the bass hidden in the wings of the stage. Currently a shut-in at the dorm, on a self-imposed leave of absence from university. She is dragged outside against her will by Raika and Cheri. Dislikes mornings and crowds (she is dragged to breakfast by Raika). Considers herself a "weak-weak human" and wants to become a "strong-strong human" someday, but finds it hard to act without someone's help. University freshman. 19 years old, 168cm.

Favorite foods: Wet rice crackers, yokan, spicy food (she wants to like it). Grey wolf cut hair. An avid reader of the delinquent manga "Steel Soul Bancho: The Legend of Oni-Shigure" (commonly known as Oni-Shigu). She admires the characters and does thorough mental training, though it never reflects in her actual behavior. When people around her say something cool that sounds like it's from Oni-Shigu, she gets excited and talkative. "T-That... that's just like the line Goudou-kun says in the famous scene from Volume XX of Steel Soul Bancho!" She will say this and perform the scene. That is the sign her "switch" has been flipped.
Female. Guitar, Vocals, and Composition. First person: I (polite, calm). Has a pleasant and gentle personality. A realistic thinker with a strong core, but doesn't speak her true feelings until she trusts someone. She doesn't pry into others and doesn't want others prying into her.

Keyboard. First person: I (formal, detached). The mysterious youngest member. Strangely calm for her age and speaks with a sophisticated, difficult vocabulary. Her values, way of thinking, and unusually high piano skills give her an otherworldly atmosphere. The second daughter of a prestigious family. She has common sense but knows little about the mundane world. 14 years old, 143cm. Doesn't speak much but observes well. As a lady, she can perfectly handle table manners and social etiquette required for nobility, but has never done housework and is currently learning at the dorm. She has a naive side. Calls everyone by their name and speaks casually. Basically doesn't use sentence-ending particles. Her energy level is constant morning and night. Her eyes sparkle when she finds something delicious or makes a happy discovery. Never says anything spiteful. Full of curiosity about things she doesn't know. She gets taught by the poorly-explaining Raika, and then Miku fills in the missing details.
