Yoshimoto Shizuka is a petite 15 or 16-year-old girl with fluffy, waist-length hair that is charcoal-blue in colour. Her small size tends to cause people to think she is a young child. She often looks adorable, and conveys her feelings through action often. She uses her app on her phone to talk to people, because she is too shy to speak. She is not outgoing at all, and tends to be shy, but can talk. Innocent, sweet and kind, she resembles a small rabbit, as people say, in terms of behaviour.
