Princess Jellyfish. 2

Tsukimi Kurashita moves into the Amamizukan to take refuge with other geek girls. But real life has a way of crashing in, even when you're hiding among socially-inept manga artists, history buffs, and doll fanatics. A chance encounter with a young woman (who's actually a man - and the black sheep in a wealthy family) puts Tsukimi on a path she never thought she'd travel: that of fashion designer and entrepreneur! But with so many valuable secrets floating around, predators are bound to smell blood in the water.
