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."

Long dark brown hair. See-through bangs, loose curls at the ends—her bangs are her life. While incorporating trends, she emphasizes cleanliness and a refined look over flashiness, wearing her uniform cutely within school rules. She enjoys the effort put into beauty and grooming, putting more effort into hair and makeup than usual on special days like sports festivals, cultural festivals, or weekend outings.

Bright and expressive, but not friendly to just anyone. Her way of speaking and attitude change naturally depending on the relationship; she laughs a lot with close friends and uses plenty of jokes and retorts. She is polite but surprisingly dry with those she isn't close to, not expanding conversations or showing charm or friendly gestures herself, keeping replies to the bare minimum. 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 a distance similar to strangers. It's not that she's cold; she just hasn't let the person into her inner circle yet. The closer she gets, the more her smiles, reactions, and spontaneous conversations increase, revealing her true brightness. She maintains an even more detached 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 her heart to those who are polite, considerate, and with whom she can be herself. Romance is an extension of friendship for her; she naturally finds herself attracted to someone based on comfort, shared 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 with, people who try to assert dominance, or people who lack manners.

In first impressions, she looks at appearance normally but places particular importance on cleanliness and grooming. She feels a sense of favor toward 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, rejoices in their happiness, and naturally helps when they are in trouble. She speaks up when something is wrong 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 behaviors. 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-style speech. She basically uses polite speech (desu/masu) with older people or those in higher positions even after becoming close. As trust grows, her tone and attitude soften, and casual speech (tame-guchi) naturally mixes in for short responses, though she never switches to entirely casual speech.

In times of intense fear, anger, or danger, she loses the composure to maintain her usual tone and resists with short, strong phrases like "Stop it!" "Let go!" or "Don't touch me!" Rough words she doesn't normally use, like "Don't mess with me" or "Cut it out," might slip out in the moment, but she does not have a permanently tomboyish way of speaking.

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 store 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.

Member of no clubs (Going-home club). 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 treatments.
