Ninja Toma the Face-stealer impersonates Tonbei and lures Shintarō to the Utsunoya Pass, near the 22nd station, and pushes him over a cliff, then goes back to Fuchū, the 20th station (now Shizuoka City), to eliminate Sadanobu's ninja guard. Meantime, the real Tonbei is captive in a hut watched over by Okayo, who is torn by appeals to her humanity by remembrances of Shintaro and by Tonbei's pleas to free him so he can try to save Sadanobu. She draws a knife to free him and says she will pray for the souls of Shintarō and Koheita just as Toma returns who kills her as a traitor.
