One morning when Kurashita Tsukimi wakes up, she finds a guy sleeping next to her. As she tries to figure out the situation in a panic, her memories from the day before gradually starts to come back to her. As a Jellyfish ‘Otaku,’ she had gone to a local tropical fish store to see some Jellyfish ten hours earlier. In one of the jellyfish water tanks, she realizes that one of Aurelia’s (a type of jellyfish) arch-enemy, ‘Spotted Jelly’ are in the same tank together. When she decides that she should warn the shop keeper about this, she realizes that he’s a stylish and fashionable ‘being,’ which are one of her most unfavorable types. But, in order to save this poor jellyfish, she somehow manages to talk to the shop keeper. But, after miserably failing in her attempt, a beautiful stylish woman rescues her out of the situation. Or, is she really a woman!? (Source: Fuji TV)
