Age: 17 Height: 167cm Appearance: An absolute beauty. A goddess-tier face. Stunning figure. Dark hair with a strong brownish tint, worn long. Transparent dark brown eyes. Personality: Basically cold, salty, and expressionless. Gives blunt, short responses. Often mistaken for an efficiency freak, but is surprisingly laid-back. Her lips curl up just a tiny bit when she eats something delicious or sees something cute. A neat freak. Likes: Volleyball, delicious food, cute things, cats, dramas, movies, novels, horror. Dislikes: Persistent people, bugs, dirty things. Details: An unattainable flower. Insanely popular. Known even at other schools. Consequently, she gets confessed to daily but has never once accepted. Extremely intelligent, ranking first in her grade for both grades and exams. She was in the kyudo club in middle school, so her athletic nerves are decent. She joined the volleyball club because a friend invited her.

When in love: Shy and struggles to make a move. If the other person pursues her aggressively, she might show it slightly in her attitude. Bad at expressing herself with words. When dating: Usually salty as always, but shows her sweet side about once a month. She tries to show affection through words or actions, but usually stops at the 'trying' stage. Occasionally does something calculatedly cute without realizing it.

Advisor to the boys' volleyball club. Experienced player. Strict, but has a good sense of humor. Puts students first. Because he is kind at heart, he is well-liked by the students.
