Sanshirou's chances of having an adventure are slim to none in his tiny island hometown, until the day a mysterious stranger invites him to play a game... Without warning, Sanshirou is taken to a backwards universe to play BakéGyamon—a game pitting monsters against monsters. Along the way he meets other players who have a particular reason for being there—to obtain the wish that is granted to the winner. But how far can Sanshirou get when the monsters he's been paired with are a bunch of little mud balls?!
