Sex and the Amars

Tsukimi Kurashita is an 18-year-old otaku living in an all-female apartment building, Amamizukan, with other women otaku. One day, Tsukimi, who has an intense love for jellyfish, tries to go to Shibuya for a jellyfish exhibit, but turns back when she becomes apprehensive at all the stylish girls walking around Shibuya. Later, when reminiscing about her dead mother, Tsukimi goes to see a spotted jellyfish she named Clara at a local pet store to cheer her up. She is shocked to find a moon jellyfish in the same tank, as this will eventually cause the spotted jellyfish to die. Overcoming her fear of talking with the stylish male shop clerk, Tsukimi tries to explain the imminent danger to the jellyfish, but is pushed back when she tries to enter the store. She bumps into a stylish woman outside the store, who eventually reasons with the clerk to give Clara to Tsukimi, since it will die anyway. They take it back to Amamizukan and put it into the bathtub for the night. The woman stays the night, and the next morning Tsukimi discovers the woman is in fact a cross-dressing man.
