Based on a bishoujo game (an ero-game).
But the anime will not be an ero-anime.
The game got released on 21/4/2006.
Game creator: UNiSONSHIFT BLOSSOM
Noiji Ito (the illustrator of the seinen light novels Suzumiya Haruhi and Shakugan no SHANA) also worked on this game so Yay Yay
Genre: Seinen, Fantasy, Romance
As time passes, seems more anime are being made based from bishoujo ero-games I usually play XD, well looking forward to this.
