With confidential Nue files having been leaked to their enemies at Kuchinawa, a search is underway for the traitor who provided the information.

Asahi and Yukimura struggle with the nature of their relationship, while the mole leaking Nue secrets is found... or is he?

Now that her revenge is complete, Sawa doesn't know what to do with herself. With Tsukishima on the run and Elena facing a major change, what will become of the agents of Nue now that their primary target has been dealt with?

It's become clear that Nue agents don't leave the shogun's service and live to tell the tale, so it's up to Asahi to find a way for Sawa to break free of the life of violence she's become trapped in.

After faking Sawa's death, she and Asahi have fled Tokyo for a peaceful life in the country... but can they really escape the cycle of killing?
