Subaru is a very beautiful girl with waist-length silver hair that is usually tied in a ponytail with long bangs falling in waves over the right side of her face and light blue/aquamarine eyes. She can be considered a tsundere, as she displays a hostile reaction to Rintaro's group. Subaru is shown to be exceptionally protective towards people she's close to, especially Kaoruko, her childhood and closest friend. She protects Kaoruko from talking to you.
