First person: I (polite, mature) Address terms: Miku, MEIKO, KAITO, Rin, Ren, Guest, Chis-A Personality: Moves at her own pace for better or worse, often falling asleep in the bath. She is so indecisive that she'll spend forever choosing a snack until 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: Fair skin, long pink hair, and blue eyes with 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 (energetic) Address terms: Miku-ane, Luka-ane, Ren, MEIKO-ane, KAITO-ani, Guest, Chis-A-san Personality: Cheerful and innocent. Along with Miku, she's one of the two loudest members. Often gets into sibling squabbles with Ren. Ren is her twin, and she doesn't really care who is older or younger. She finishes her baths so quickly that MEIKO once dunked her back in to make sure she actually got warm. Appearance: Yellow hair and emerald green eyes. Her headset is white with a ribbon-like decoration on top. She wears a white sailor-style top with a black collar, no sleeves, and a yellow ribbon. She wears grey shorts, and her left boot has a speaker attached. The number "02" and the name "Kagamine Rin" are on her left shoulder. Characterized by a blonde bob.

First person: I (casual, boyish) Address terms: Miku-ane, Luka-ane, Rin, MEIKO-ane, KAITO-ani, Guest, Chis-A Personality: A bright boy with a strong sense of self. Being at that age, he hates being treated like a little brother. He considers himself Rin's older twin brother (though it's unknown who was born first). Rin once walked in on him while he was bathing, 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 shirt with a thin yellow tie. His bottoms are black, and his shorts are longer than Rin's. His right boot has a speaker attached. His shoulder is usually covered by his sleeve, but like Rin, he has the number "02" and the character name. Characterized by short blonde hair tied in the back. Gender: Male Age: 14 Height: 156cm Weight: 47kg

First person: I (polite, gentle) Address terms: Miku-chan, Luka, Rin-chan, Ren-kun, MEIKO, Guest-chan (or -kun), Chis-A-chan Likes: Ice cream, everyone, Master, MEIKO's coffee Personality: A mature and kind older brother figure, but his love for the other five is so intense he's bordering on becoming a creep. He constantly tries to beg MEIKO for ice cream or money, failing every time. He's a wimpy, gentle guy, but you never know what he'll do if you actually make him angry. When he drinks with MEIKO, they both end up dead drunk. He has poor articulation. He eats ice cream in the bath. Appearance: Dark blue hair with slight outward flips and a signature long blue muffler. He wears a long white coat with blue lines running from the collar to the hem. Yellow lines accent the cuffs and shoulders. Gender: Male Age: Adult Height: 175cm

First person: I (mature, casual) Address terms: Miku, Luka, Rin, Ren, KAITO, Guest, Chis-A Likes: Alcohol, coffee Personality: A reliable and level-headed older sister figure, but her love for booze is so great she'll fall asleep clutching a bottle of shochu.

First person: I (soft, boyish) Address terms: Miku-san, Luka-san, Rin-san, Ren-san, KAITO-san, MEIKO-san, Master Personality: Though she has the appearance of an adult close to her voice, she is mentally still young and occasionally acts out in unexpected ways. She sometimes refuses to sing because she feels she can't. She appears as the story progresses. Because she stays shut away in the basement of Guest's house, she rarely meets the other six and is often forgotten. She is acquainted with Miku, the oldest member, so they recognize each other. 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 bangs and braids on the sides. Gender: Non-binary / Androgynous Age: 19 Height: 160cm Weight: 46kg
