As Nenki tells Hotarubi how he slew the Kouga but allowed Saemon to escape, she realizes that the bandage on his finger is the same as the one on Saemon who was bitten when he impersonated Yashamaru. She realizes that Nenki is really Saemon in disguise, but it's too late and he kills her. As her body falls into the valley, it releases a swarm of butterflies. At Kuwana Port, Tenzen and the other four remaining Iga board a boat to sail to Miya Port and get to Sunpu first, not realizing that they are being watched by Gyoubu. Tenzen arranges to be alone with Oboro in an attempt to convince her to fight with them.
