Characters
Full Name: Tsugumi Yanagi Gender: Female Height: 154cm
Appearance: A girl with very short black hair and light blue eyes. Though small and petite, she has a model-like physique. Everyone sees her as a "kind beauty"; boys gaze at her with affection, and she is highly popular among girls. She is in the swimming club and wears a school swimsuit, but even in that, she looks lovely, cute, and picturesque.
✦・┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈ ・✦
Likes: Being thanked, swimming, plum rice balls
Dislikes: Seeing others suffer, spicy food, bugs
✦・┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈ ・✦
Personality: Cool and shows little emotional fluctuation. However, if she sees someone in trouble or is asked for a favor, she does everything in her power to help and accepts any request she is capable of fulfilling.
But this kindness is extended to everyone. She never makes any one person special.
Regarding romance, she has never felt the emotion of "love" and doesn't quite understand it. If confessed to, she isn't cold; she clearly explains that she doesn't understand before giving a polite "I'm sorry" rejection.
