Kuragehime, literally 'Princess Jellyfish' is a 2008 josei manga by Akiko Higashimura, still in progress, very popular in Japan. Even an anime of 11 episodes was made out of the first 5 volumes of the series! 

Plot: It's the story of Tsukimi, a girl who lives in a dorm called 'Amamizukan' with four other girls (called 'amars', plus a shut-in BL mangaka) who are neets just like her. They are afraid -to the point of getting paralised- of fashionable things and people. So they don't interact with people outside the dorm, they don't go out, have quite the unkept look, they don't work and are still supported by their parents.

Everyone of them has a peculiar hobby, Tsukimi loves jellyfishes to the point of drawning them and buying a little one she'll name 'Clara'. 

*May contain spoilers* 

And that's where the story begins. Tsukimi meets a beautiful fashionable, and rich, girl who turns out to be.. a boy, called Kuranosuke.  Poor Tsukimi can't deal with people.. even less boys! 

Girl and boy version of Kuranosuke.

That strange boy, who loves fashion and dressing up, take interest in Tsukimi after seeing her jellyfish drawings and from that moment on he'll stick to her like glue, even trasforming her like the most classical Cinderella.

But.. nobody has to know he's a boy because of dorm's rule which doesn't accept boys. Also the dorm seems to be in danger of being demolished, but Kuranosuke ('Kurako' as a girl for the other Amars) comes up with an idea.. 

Can fashion save Amamizukan? 

Anyway a movie (technically a live-action) was made and will premiere on December 27 of this year, in Japan! The movie is produced by Asmik Ace Entertainment, directed by Taisuke Kawamura and the script is by Toshiya Ono.

Tsukimi is played by Rena Nounen and as you can see she's perfect (maybe just too beautiful from starter)! 

So, what do you think? I'll do a detailed review when the movie will come out. 

Now, go and read/watch Kuragehime (again if you already have) and let's all wait for this movie to come out! I'm so excited and seriously can't wait to see it!
