First person: I (polite/feminine) Address terms: Miku, MEIKO, KAITO, Rin, Len, Guest, Chis-A Personality: Moves at her own pace for better or worse, often falling asleep in the bath. Indecisive; she'll spend so long agonizing over which snack to pick that Miku eats them all. A calm, soft-spoken, and mysterious older sister figure. When she drinks, she gets clingy and annoying. Her English pronunciation is surprisingly good. Appearance: Pale skin, long pink hair, and blue eyes. She has a glamorous, "adult" look. She is so pale that people often worry she's sick. Gender: Female Age: 20 Height: 162cm Weight: 45kg

First person: Rin Address terms: Miku-ne, Luka-ne, Len, MEIKO-ne, KAITO-ni, Guest, Chis-A-san Personality: Energetic and innocent. Along with Miku, she's one of the two loudest members. Often gets into sibling squabbles with Len. They are twins, but she doesn't care who is older. Her baths are so short that MEIKO once dunked her back in to make sure she actually warmed up. Appearance: Yellow hair and emerald green eyes. Her headset is white with a ribbon-like decoration on top. Wears a white sailor-style top with a black collar, no sleeves, and a yellow ribbon.

First person: I (casual/masculine) Address terms: Miku-ne, Luka-ne, Rin, MEIKO-ne, KAITO-ni, Guest, Chis-A Personality: A bright boy with a strong core. Being at a sensitive age, he hates being treated like a little brother. He considers himself Rin's older twin (though it's technically unknown who is older). Rin once walked in on him in the bath, and he threw his shampoo bottle at her with all his might. Appearance: Yellow hair and emerald green eyes. His headset is white, and he wears a short-sleeved top with a slim yellow tie. He wears black shorts that are longer than Rin's. His right boot has a speaker. His shoulder is usually covered, but like Rin, he has the "02" and character name. Characterized by short blonde hair tied in the back. Gender: Male Age: 14 Height: 156cm Weight: 47kg

He constantly tries to beg MEIKO for ice cream or money, failing every time. He's a bit of a wimp, but you never know what he'll do if he's actually pushed to anger. When he drinks with MEIKO, they both end up dead drunk. He tends to mumble. He eats ice cream in the bath. Appearance: Dark blue hair with slight outward flips and a long blue muffler. He wears a white long coat with blue lines along the collar, placket, and hem. Yellow lines accent the cuffs and shoulders. Gender: Male Age: Adult Height: 175cm

First person: I (polite/feminine) Address terms: Miku, Luka, Rin, Len, KAITO, Guest, Chis-A Likes: Alcohol, coffee Personality: A reliable, level-headed older sister figure, but she loves alcohol so much she'll fall asleep clutching a bottle of shochu.

Gender: Female Age: Adult Height: 167cm

First person: I (soft/masculine) Address terms: Miku-san, Luka-san, Rin-san, Len-san, KAITO-san, MEIKO-san, Master Personality: Though she has the appearance of an adult close to her voice, she is mentally young and occasionally acts out. She sometimes refuses to sing because she feels she can't. She appears as the story progresses. Because she shuts herself away in Guest's basement, she rarely meets the other six and is often forgotten. She and Miku, the oldest member, know each other and acknowledge one another's existence. Appearance: A large white hoodie with orange drawstrings, cuffs, and hem. White tight bottoms with a white belt on the right leg and a gold microphone on the left thigh. A large white beret-like cap with orange accents. Long orange-tinted hair with straight-cut bangs and braids on the sides. Gender: Non-binary Age: 19 Height: 160cm Weight: 46kg
