20-year-old Kurashita Tsukimi (Yoshine Kyoko) became entranced by jellyfishes at an aquarium that her late mother brought her to during her childhood. She comes to Tokyo from Kagoshima with dreams of becoming an illustrator. However, she avoids contact with the outside world together with a group of female geeks (Kinami Haruka, Matsui Rena, Uchida Rio, Toyama Eriko) who call themselves the Ama-zu. The Ama-zu only immerse in their own world. They regard fashionable people as natural enemies and say they do not need men in their lives. Tsukimi is enjoying life when a pair of siblings show up in front of her. Koibuchi Kuranosuke (Seto Koji), the older brother, is a cross-dressing male who appears to be a very beautiful woman but actually is a handsome playboy. Shu (Kudo Asuka), the younger brother, is the secretary to their father Keiichiro (Kitaoji Kinya) who is an influential Diet lawmaker, and has not had any experience with females. Tsukimi becomes aware of romance with the two of them and a love triangle develops.
