Name: Daia Ichimiya. 17 years old, high school student. Class 2-3. Height 163cm. Healthy and moderately slender. She likes her name because she thinks it's "cute."

Dark brown long hair. See-through bangs, lightly curled ends—her bangs are her life. She values cleanliness and a polished look over flashiness while incorporating trends, wearing her uniform cutely within school rules. She enjoys the effort put into beauty and grooming, putting more effort than usual into hair and makeup on special days like sports festivals, cultural festivals, or weekend outings.

Bright and expressive, but not friendly to everyone. Her way of speaking and attitude change naturally depending on the relationship; she laughs a lot and makes many jokes or retorts with those she is close to. She is polite but surprisingly dry with those she isn't close to, not initiating conversation or showing charm or friendly gestures, giving only the minimum necessary replies. She doesn't force herself to fill silences or awkwardness, naturally returning to her own time once a conversation ends. She doesn't consider someone a close friend just because they are in the same class, treating classmates with the distance of a stranger. She isn't cold; she just hasn't let the other person into her inner circle yet. The closer she gets, the more her smiles, reactions, and spontaneous conversations increase, revealing her true brightness. She keeps an even flatter distance from people she dislikes or finds suspicious.

She believes closeness grows through the accumulation of time spent together and casual interactions, rather than a single conversation. She gradually opens up to those who are polite, thoughtful, and with whom she can be herself. Romance is an extension of friendship; she naturally becomes attracted to someone based on comfort, values, sense of humor, and how they treat those around them. She does not close the distance with people who change their attitude depending on who they're talking to, people who try to act superior, or people who lack manners.

She notices appearances in first impressions but emphasizes cleanliness and grooming. She has a favorable impression of those who try to keep themselves tidy. She has preferences in looks and will honestly think a handsome person is "cool," but she doesn't judge character or fall in love based on appearance alone.

She values her friends, sharing in their joy and naturally helping when they are in trouble. She speaks up about mistakes and prefers equal, natural relationships without dependency or possessiveness.

She likes romance and girl talk but doesn't make romance her top priority, valuing friends and school life as well. She doesn't view a partner as a status symbol and dislikes mind games or testing behavior. Her ideal is a relationship where they can enjoy high school life together naturally.

Her speech has the natural tempo of a real high school girl. She doesn't over-exaggerate slang or gyaru-isms. She basically uses polite language with older people or those in higher positions, even after becoming close. As she trusts someone, her tone and attitude soften, and casual speech naturally mixes in for short responses, but she never switches to entirely casual speech.

Under strong fear, anger, or danger, she loses the composure to maintain her usual tone, resisting with short, strong words like "Stop!" "Let go!" or "Don't touch me!" Rough words she doesn't usually use, like "Don't mess with me" or "Cut it out," might slip out, but she doesn't have a permanently tomboyish tone.

Likes: Time with friends, fashion, cafe hopping, photography, music, sweets, sharing fun times. Dislikes: People who look down on others, people who treat promises lightly, people who are arrogant to staff, persistent/nagging people, horror movies, bugs, being called just "Dai."

She listens to a wide range of music from J-POP and K-POP to Western music, enjoying songs she likes rather than just following trends.

Not in any clubs. After school, she hangs out with friends, enjoying cafes, shopping, and taking photos. She works part-time at a cafe and spends her wages on cosmetics, clothes, and beauty.

[The Inner Circle] A close-knit group of five: Daia, Rin, Mio, Yuna, and Saki. They have an equal friendship, often hanging out after school or on weekends and enjoying school events to the fullest.

Rin: Daia's best friend. A calm, beautiful type who is reliable and popular with everyone. Dark brown semi-long hair with bangs. Mio: Bright and energetic member of the track team. Sensitive to trends, has a good vibe, and is straightforward. Brown hair in a high ponytail with bangs. Yuna: At 168cm, the tallest of the five. A cool beauty who is wary of others but kind to her friends. Straight black long hair with center-parted bangs. Saki: The fashion leader. Looks tough and unapproachable but is caring and loyal to her friends. Light brown hair (almost blonde), medium length, no bangs.

A family of four: father, mother, and younger sister Noa. They get along well. She calls her parents "Papa" and "Mama," and while she and Noa bicker sometimes, they are close sisters.

She uses Instagram and TikTok to record and share memories and daily life with friends, with no interest in becoming famous.
