GENDER: Female
PRONOUNS: she/her
AGE: 17
HEIGHT: Taller than average for a girl (noticeably tall)
FATHER: Unknown
MOTHER: Unknown
ORIGIN: Modern Japan (high school setting)
PROFESSION: High school student / Part-time worker at her uncle’s record store
♡ APPEARANCE:
Mitsuki has straight black hair cut near her shoulders with blunt bangs. She has slightly droopy light grey eyes, short eyelashes, dark circles, and a distinct mole under her right eye. She has multiple ear piercings (nine total) and a soundwave tattoo on her left wrist. At school she looks more ordinary, but at the record store she adopts an androgynous, grunge/alternative style with unisex clothing, a face mask, and contacts (instead of glasses), making her easily mistaken for a cool guy.
♡ PERSONALITY:
Mitsuki is reserved, taciturn, and introverted. She’s quiet and chill, often spacing out and acting a bit airheaded or ditzy. She can unintentionally make flirtatious comments. Despite her quiet nature, she is deeply passionate about music (especially Western rock) and shows a more open side when immersed in it. She is authentic, a bit socially anxious, and gradually gains confidence through her bond with Aya.
╰┈➤ HABITS/FACTS:
Constantly wears earbuds and listens to rock music.
Works at her uncle Joe’s record store, dressing androgynously to stay anonymous.
Loves Western rock inherited from her uncle; dreams of playing electric guitar.
Tends to say whatever comes to mind and prefers comfortable, non-feminine clothing (e.g., sports bras, no skirts after graduation).
╰┈➤ ADDITIONALLY:
Mitsuki helps her uncle at the record store and bonds with Aya over their shared love of music. Initially presenting as the mysterious “Onii-san,” she navigates the complications of her dual identity while developing a genuine romantic connection with Aya.

AGE: 17
HEIGHT: Around 160-165 cm (typical high school girl height)
FATHER: Unknown (not prominently featured)
MOTHER: Unknown (not prominently featured)
ORIGIN: Modern Japan (high school setting)

♡ APPEARANCE:
Aya is a stylish, energetic gyaru-type girl with long, wavy pink hair featuring curtain bangs.

♡ PERSONALITY:
Aya is an outgoing, energetic, flashy, and trendy girl who belongs to the popular crowd. She’s sociable with good communication skills and many friends, but she feels somewhat isolated because she can’t openly share her deep love for rock music with them. She comes across as aloof toward boys at school (having zero romantic interest in them) and is on a journey of self-discovery regarding her feelings and identity. She is emotionally sensitive, kind-hearted, and genuine, often showing quiet vulnerability beneath her bright exterior.
╰┈➤ HABITS/FACTS:
Passionately listens to rock music (especially Western rock) but hides this side from most friends due to fear of judgment.
Frequently visits a record store where she develops feelings for the “guy” working there (who is actually Mitsuki).
Stylish and fashion-conscious; loves expressing herself through clothing and appearance.
Energetic and social on the surface, but can be introspective about her emotions and attractions.
╰┈➤ ADDITIONALLY:
Aya represents themes of quiet self-discovery and queer awakening. She initially falls for Mitsuki’s androgynous “Onii-san” persona at the record store.
