I just came upon the anime today, and I've watched the first two episodes. It's really good! The OP was enough to get me into the show!

It's about an apartment for women only, inhabited by otaku fujoshi, each with their own quirky obsession. The main character, Tsukimi, is infatuated with jellyfish, since her mother would take her to aquariums as a kid, and told her how she would make a dress for her that looked like the jellyfish there. She gets a complex about it, and loves dresses that resemble the jellyfish she saw.
Enter Kurako, a crossdressing politician's son, who is very fashion conscious. He "rescues" a jellyfish for Tsukimi, and invites himself over. The residents of the otaku-house are averse to Kurako on sight, not because he's actually a guy, but because she's "Stylish," a curse word among their sisterhood of geekery.
I really like the show because for once, I feel like I can totally relate to the characters. That's sad, isn't it? Even so, it's a very light-hearted and fun show. Definitely worth checking out!
