Raikō tells Gintoki to find and destroy the ghosts who are killing the samurai. Gintoki encounters the two women and realizes that they are Yone (his mother) and Shige (his wife). They have made a pact with the underworld to return and kill samurai in revenge for their deaths. Because Gintoki has become a samurai, by their pact they must kill him, but Shige breaks her pledge to spend seven nights of love with Gintoki. Then, because she has broken the pact, Shige is condemned to the underworld. Gintoki lies to Raikō that he has destroyed one of the ghosts.
