Yuzuki Mizusaka (水坂 柚季 Mizusaka Yuzuki?) is one of the main characters of the Sora no Method series.
Yuzuki is a girl of seemingly average height. She has short, light brown hair which she pulls back with a white hair band. Her bangs, separate from the rest of her hair, covers her forehead. Yuzuki has light brown eyes, much like her hair. She is usually seen in her school uniform, which includes a brown-and-white dress and a pink cape, tied at the top with a red ribbon. She wears white leggings and brown shoes as well.
Yuzuki is a rather energetic and determined girl, who hardly changes her mind when her decision has been made. This is shown when she refuses to stop spreading the message of getting rid of the saucer and even asks for Nonoka's help. Yuzuki seems to also have a short temper, as shown when she yells at Koharu for telling her to stop disturbing the customers. She may jump to conclusions and act without thinking when she is upset.
