The VOCALOID2 Project and Hatsune Miku are without a doubt one of the most successful examples of Viral Marketing in recent history: Slap a cute anime girl onto an equally cute (and sometimes a little creepy) synthesized voice and let the people with too much free time take over, churning out more anime covers than you can shake a stick at. Now, on top of cameo appearances in certain online golf games, it seems the 2D superstar is getting her own PSP game.

Project DIVA is divided into two parts. The first is a rhythm game part in which you will play songs (Whether they’ll be covers or original works is unknown at this point) in the classic match-the-command style. By playing through these you unlock items to put in a room that you design for Miku, which you can then… watch. The room’s music will change depending on the items that you put into it, and Miku will also react and try out every new item that you place. It’s hard to say whether this game is aimed at rhythm game fans or virtual pet buffs, but it’s something you can’t count on seeing here. No date has been given for the release, but Japan will see it some time next year.
