Tsukimi is a plain and shy illustrator who has a deep fascination with jellyfish, a far cry from her idea of a princess. She shares her mundane life with her roommates who are passionate about their hobbies, but are also considered social outcasts. These introverts have established strict rules that resemble those of nuns, which inevitably change when Tsukimi rescues a jellyfish and a beauty queen who happens to be a man. When their safe haven is threatened, the glamorous guy behind the transformation of this eccentric group from rejects to triumph, will Tsukimi muster up the courage to seize the opportunity to flourish, or will she fall apart?
