20 year old Tsukimi Kurashita (Kyoko Yoshine) can barely see without her glasses. She came to Tokyo from Kagoshima Prefecture to become an illustrator, but she doesn't attend college or sells any of her illustrations. She lives at a communal apartment. At the apartment, only otaku type women live there. Tsukimi Kurashita likes jellyfish due to memories she has with her late mother. One day, due to a jellyfish, Tsukimi Kurashita meets Kuranosuke Koibuchi. He loves fashion and his hobby is to dress up like a woman. She also meets Kuranosuke's older brother Shu Koibuchi. Her life soon changes because of them.—AsianWiki

Tsukimi Kurashita (Kyoko Yoshine) lost her mother to illness while she was still a young girl. Her enduring memory of her mother is jellyfish - after an emotional visit to an aquarium with her mother. Ever since, she has been completely obsessed with these aquatic creatures. She lives in a Tokyo apartment with a group of young women on the fringes of society, most of whom have little or no romantic experience, shun outsiders, and are unemployed. Tsukimi Kurashita dreams of escaping this dreary apartment and her housemates. She wants to retreat into her own world and become an illustrator. But her life is sent on a brand new course on the fateful day when she quarrels with an uppity pet store clerk about a jellyfish, which she believes may be on the verge of death. A remarkable looking stranger intervenes: a stunning beauty queen (who later turns out to be a cross-dressing man): Kuranosuke Koibuchi (Koji Seto). The stranger buys the jellyfish for Tsukimi Kurashita, who repays the favor by letting this exotic beauty stay with her at the apartment - much to the disdain of her housemates. But the chaos has only just begun, as both Koibuchi Kuronosuke and his brother Koibuchi Shu (Asuka Kudo) slowly begin to fall for Tsukimi Kurashita.—Rakuten Viki
