Bakemonogatari , the famous anime series based on novels by Nishio Ishin, will have its own PSP game, Bakemonogatari Portable , released in Japan this August.
There's a limited edition version with its own PSP case, a DVD and CD with bonus content, and a special booklet with gaming info.
Aiming to keep the anime series' unique feel, the game apparently doesn't fit in any existing genre per se. Unfortunately, further details on the game has yet to be released.
