A battle with witches ended in victory for the samurai centuries ago, but their war is far from over. Yurei, an ancient witch whose ancestor was slain by the legendary warrior Kai, has surfaced in modern day Budapest seeking to unite both halves of the fabled Tengu Sword. Prophecy claims a descendent of the 47 Ronin can wield that blade to defeat Yurei's evil. Some suspect Luna, a streetwise New Yorker, possesses that power, and it's up to ronin Reo and apprentice Onami to build her body into a weapon. With their lords mysteriously missing, and a traitor hiding among them, the samurai must summon all of their skills as martial arts masters to combat the mystic magic of the witches and uncover the truth about their bloodline's destiny.
