Princess Jellyfish

Tsukumi Kurashita is an 18-year-old girl and young artist who dreams of becoming an illustrator. In order to succeed and make her dream a reality, she moves to a girl-only apartment complex in Tokyo, Amamizukan. Due to the fact that men are strictly forbidden to stay there, the "residents" of the building are nicknamed "nuns". She has been fond of jellyfish since she was a child and keeps one at home as a pet. One day, while attending a sea creature show, her jellyfish gets into trouble. She is the son of a jellyfish and she is the one who rescues him from the jellyfish trade show. Tsukimi goes to her house to thank Kurara, the rescuer of her pet jellyfish. When she wakes up in the morning she realizes that her new friend isn't a girl at all, but a real-life guy named Kuranosuke. When she awakens, she realizes that the girl she's dating is not a girl at all, but a boy named Kuranosuke. Now the fun begins at the nuns' house - despite the fact that men aren't allowed in here, this guy with the weirdness will appeal to the girls with the "cockamamie" in mind.
