In the world of the Ninja, fighting skills play a small role in one's rank in the Shinobi order. Kageru is the best in his class, but his birth predestines him to the lower class. His friend Aoi is dealt the same fate; together they'll have to question themselves.

Beleaguered police detective Nishi takes desperate measures to try and set things right in a world gone wrong. With his wife suffering from leukemia and his business partner paralyzed from a brutal gangster attack, Nishi borrows from a yakuza loan shark and then robs a bank to clear his debt.

Hunted. Kagerou and Aoi have managed to escape the powerful clutches of Shuuzan and his men as well as the vengeful rage of Jinsei - the Shinobi Murderer. But, their troubles are far from over. If Kagerou and Aoi are to have any hopes of survival, they must get out of Iga. But between themselves and the border stands a barrier of both friends and enemies - neither of which can they trust.
