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?

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.

With her life in tatters, Sawa struggles to find a reason to keep going. Accompanied by another Nue executioner, she decides to look to her past while considering her future.

Sawa confronts Jin Kuzuhara about the truth behind what happened to her family and her village, but before she can get real answers a squadron of the shogun's troops arrives to try and capture her.
