Gintama Movie 3: Yoshiwara Daienjou

Gintoki meets a young pickpocket named Haruta and learns that the boy is stealing not out of greed but because he longs to see his mother, Hinowa, the most celebrated courtesan in Yoshiwara. Gintoki, Kagura, and Shinpachi descend with him into the underground city, where the Night King Housen rules through fear and overwhelming strength.

A simple attempt to reunite a mother and son becomes a rebellion against the system that has kept Yoshiwara's women imprisoned for years. As Kagura confronts the violent legacy of the Yato and Gintoki faces an opponent who may outclass him, bringing even one ray of light to the city of night becomes a fight for everyone's freedom.
