After Sawa learns that Yoshinobu himself ordered Kuzuhara to have the Treasurer killed, Makoto suggests that Sawa drop the “sister act” and cut little Asahi loose. All of them in Nue have assigned roles to play, and none of them can afford to let sentiment dull their wits.
After recalling when Kuzuhara first showed her a slideshow of her family and village’s destruction and the person responsible, ordering her not to cry, Sawa puts up the hard front Kuzuhara aimed to teach her in dealing with Asahi. Sawa refuses to let Asahi kill her until she’s killed Janome, and tells her to be gone by the time she returns that night.
Sawa, Elena, and Makoto all confront Nue’s cleaner, whom they suspect is a traitor passing secrets to Kuchinawa, finding money in the coffin he’s pushing. He pleads his innocence, then sets off a bomb with a detonator in his hat. Sawa follows him down a secret tunnel hidden in a tomb, while Elena intends to head him off on the surface. Meanwhile, a dejected Asahi seeks comfort in her grandmotherly neighbor Yamazaki.
But the cleaner never went in the tunnel; he hid in the coffin. When Makoto, who lied to Elena about a twisted ankle, opens it and the cleaner pulls a gun. A shot rings out, and Makoto later reports that the cleaner killed himself. But at this point Makoto was already acting super suspicious.
While burying the cleaner themselves, Elena asks Sawa what coffin she’d want to be buried in, her preference being red. Sawa doesn’t answer at first, then says blue, like her blood and that of her clan. That said, she won’t be put into a coffin until Janome is in his.
Makoto meets with Kuzuhara, who reveals he is a woman by tearing his clothes to reveal her chest binding, warning her to never forget where she stands. But Kuzuharais seemingly in the dark about where Makoto actually stands. Before the Treasurer died, she gave Makoto a karuta card that serves as a treasure map. Makoto follows it and discovers a small book that the Treasurer said could bring down “Tokugawa, Nue…all of it.”
Sawa comes home to find Asahi gone, but on her desk is the piece of paper with “Yuki” written on it Asahi had reconstructed with paste. Sawa then sees that Asahi left the satchel she gave her containing cash and a boat ticket to her new home, and blood on the walls.
Her white crow comes to help her search for Asahi, but we find out where she is first: in the clutches of Janome, who had disguised himself as Yamazaki with an elaborate prosthetic suit. We also learn that Makoto is indeed in cahoots with Janome, serving as a double agent. Or maybe triple, if Kuzuhara knows she’s infiltrated Kuchinawa.
In any case, for Sawa, who’d prefer clarity and simplicity, nothing is simple or clear, and never really was. To whit: she aims to save her would-be murderer from the man who murdered her family, and with whom her fellow Nue agent is working. Not ideal!
