Pokemon Mystery Dungeon: Age of Shadows

Hope, a seemingly ordinary human girl, is suddenly cast into the world of Pokemon, turned into an Eevee and with no memories except for her name. She is rescued by a pair of brothers: a Litten and a Sobble named Klaw and Dewey. The sons of the enforcers of the largest crime syndicate on the continent, Klaw and Dewey wish for nothing more than to escape their troubled pasts and become heroes by forming a rescue team.

The trio quickly become friends and set out to accomplish their dreams of being heroes. Along the way, though, Hope realizes that things may not be as simple as they seem. Supernatural events have started to occur, and otherworldly forces are threatening to rip the very fabric of not only the Pokemon world, but the entire universe apart. And Hope very well may hold the key to stopping this disaster from happening.
