Sayako is a Miko, destined to protect the Ayakashi Shrine of Chikuzen, she grows up surrounded by ayakashi. She is friendly, courteous and caring. Her reason (and wish) for participating in Bakegyamon is to release all the sealed ayakashi. She also hopes that one day, ayakashi and humans can live peacefully together just like long ago. In the anime, she always wear her shrine outfit, always talking about her mission to release the ayakashi.

Sanshiro'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, Sanshiro 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.
