Kurashita Tsukimi is an 18 year old 'kurage otaku' (jellyfish fanatic). She lives in Tokyo in an all-female apartment complex full of various types of otaku. They fear and despise beautiful, fashionable people while existing happily in their no-man, no make-up world.
That all changes when a 'hipster' saves the life of a jellyfish and intrudes upon Tsukimi's isolated existence. Things are made even more complicated when it turns out that the beautiful woman is actually a man in drag.
