A traveling warrior princess from a far-off land named Rutia has come to the kingdom of Audores after her father tells her the tale of a legendary blade known as the "Mahjong Sword" which is housed somewhere in the region and said to grant the owner any wish they desire. Upon her arrival, she discovers that there is some truth to this story but learns that she has to do battle with other princesses from other lands before she can uncover the secret of the sword. Each lady's latent powers can only be fully portrayed through Mahjong battles, and the blade is only passed down to women.
