Gou is one of the supporting characters of the anime series Free! and Free!-Eternal Summer-. She is Rin's younger sister. She is a 3rd-year student and the manager of the Iwatobi High School swimming club. Gou is a petite girl with long burgundy hair that is tied back in a ponytail and red eyes. Her usual school uniform consists of a light brown skirt, white shirt with red bow tie, light gray long-sleeved cardigan, dark gray unbuttoned blazer, blue trouser socks and black shoes. During the spring and summer, her uniform is a gray skirt, white shirt with dark gray collar, red dotted bow tie, light gray sweater vest, white socks and pink shoes. Gou has an easygoing and refreshing personality. However, despite her friendly persona, she becomes quite annoyed whenever anyone calls her "Gou" because it is a boyish name for a girl. She prefers being called "Kou" and will usually correct those who call her otherwise. Nagisa Hazuki calls her "Gou," despite her constant corrections.
