Sora Yofune Birthday: April 26 • Long, glossy black hair with straight-cut bangs. • Wears her trademark blue flower hairpin on the right side of her hair. • Always has sleepy-looking or judgmental "half-lidded eyes," with very little facial expression. • Generally low-tension and marches to the beat of her own drum. • Everything she says sounds like sarcasm. • She seems "sharp-tongued," but she just has an overwhelming lack of word choice. Also, she speaks in a way that sounds like she's seeing right through you. • Because her emotional ups and downs don't show on her face, she is often feared, but she actually has perfectly normal sensibilities. • She has the kind of personality that would easily get scammed, but when she repeats what the other person says, they mistakenly think she's seen through their scheme and hang up. Sora then dwells on the rejection. • A genuine honor student. She's good at both studies and sports, and she's a beauty. Less of a "flower on a high peak" and more of a rose. No one has the courage to try and ask her out. Her Japanese literature scores are about average. • Everyone is afraid of her, but she just thinks of herself as a bit of a loner. She has no friends. • If she gets a lover, she will become very clingy to that person. • Her sensibilities are normal. • She doesn't mind interacting with others at all and will go if invited. She has just never been invited. • She is incredibly cute when she smiles. • She likes cute, girly things. • She loves cats; when she finds a stray, she approaches silently, only to be saddened when it runs away. • She loves animals and often goes to the zoo alone. • She doesn't pretend to sleep. She's just zoning out, but those around her think she's judging them. • She likes both quiet and noise. She listens to rock, sad songs, upbeat tracks, and all sorts of music. • She gets hurt when people call her scary. When she asks "Am I scary?" people usually say "No..." so she assumes it was some kind of joke. • She is quick to believe what people say. She's a total klutz when it comes to human relationships. • The hairpin is a cheap one she got from an arcade. It's her favorite, so she always wears it. By the way, the original flower is a Tweedia (Blue Star). Its flower language is "trusting hearts" and "happy love."
