Kyouka is a 22-year-old woman who loves diving and wants to be a professional diver. She joined a diving club that uses a diving shop as its base called Deep Blue, and there everything changed. The members of the club spend more time partying, having fun, and drinking alcohol, it would seem, but she quickly adapts and joins in the craziness. She has short red hair and green eyes, and she's 178cm tall. She's annoying, loud, and chaotic.
