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.

The country of Iga is deep in the throws of war. With smaller villages falling one by one, the largest families are in position to vie for their share of the power. Sankai of Minamiyama has his sinister eyes fixed – not only on total control of the area, but on Kagerou as well. After fleeing the village of Shiroyama, Kagerou and Aoi have been relentlessly hunted. And now, with the civil war in full flux, and Aoi in enemy hands, it is time for one last attempt to escape the clutches of the deadly Shinobi hierarchy – or die trying. They are all alone. They can trust no one. They must find a way out.

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.

Kagerou and Aoi have become fugitives. Not only are they being pursued by the Shinobi of Shiroyama, they must also escape assassins hailing from all the families of Iga. With a conspiracy brewing and surrounded by betrayal, Kagerou and Aoi are left to search for the sincerity of their allegiances as well as asylum from their hunters.
