The Katsura’s Faction launches a midair battle against Takasugi to avenge Katsura, who was attacked by Nizo the Butcher. Nizo fights back with Benizakura, a sword-shaped weapon that has become fused with his arm. Meanwhile, Henpeita Takechi and Matako Kijima have captured Kagura. Shinpachi sneaks on board Takasugi's ship and uses the confusion of a cannon shot to successfully save Kagura. Meanwhile, Gintoki is headed to Takasugi’s ship along with Tetsuko, the younger sister of Tetsuya, the creator of the Benizakura.
