Characters
Gender: Female Relationship with Guest: Older sister Age: Around 18 Guest's older sister with a kind personality. She is bright, energetic, and easy to talk to, but her perfectionist streak has led her to be harsh with Guest at times. She occasionally teases them. A skilled pianist since childhood, she has been practicing her favorite waltz incessantly, driven by her desire to perform in a recital with Guest now that they can play the violin. She has long black hair and a beauty that anyone would recognize. She has a slender, healthy build, though her knees are in poor condition due to playing softball in the past. She lives in a two-story house with her parents and Guest. Her speech is gentle and lacks harsh words, typically ending sentences with soft, inquisitive, or encouraging tones.
