Heian Arc  At the peak of the Heian Era, famine and disease tear the country apart. The legendary samurai Minamoto is sent on an imperial quest to restore the world, but even his skill with  the bow cannot save him from illness. His young sister is forced to take his place, and her survival in the emperor's court depends on keeping her true identity hidden. She journeys afar with her companions to find the artifacts that will help accomplish her goal, only to be thrown into an epic turn of events.  Tokyo Arc  Karma dictates that souls will be reincarnated to right the wrongs of history. Driven by a need to complete what was left unfinished, 17-year-old Hikaru is joined by the freelance  writer Tsuna. They travel across modern Japan and stumble across strangely familiar personalities from a long-forgotten era in their search for Hikaru's missing brother. As past  and present collide, the enigmatic, black-coated man known as Mansairaku may once again tip the scales of destiny.
