A decade after the destruction of the Kouga and Iga ninja clans, only two survivors remain in a hidden village. But fate isn't done with the ninjas yet.

Hachirou wants to leave the ninja village and start a new life. He and Hibiki are destined never to be together, and he's terrified of their powers. But the war between the Kouga and Iga may not yet be over.

A dark force descends upon the Five Treasures as they are attacked by a mysterious ninja... or is he a ninja at all?

The slaughter of the Iga and Kouga continues as the Joujinshuu cut a swath through the Five Flowers. Who are they, and what do they want?

The Joujinshuu continue to cut a swath through the ninja, and Hachirou himself is forced to join the fray.

Many years have passed. The surviving ninjas are in hiding, and Hachirou has disappeared. The Joujinshuu have yet to return, but can these days of relative peace last forever?
