Katsura introduces the new Jouishishi member Shou-chan i.e., the Shogun and decides to teach him how to be an effective leader. He ends up getting more that he bargained for when the new member out-shines him in every way. Both leaders devolve into a rivalry with poor Gintoki caught in the middle.
Back at the Jouishishi headquarters, Katsura and the rebels are planning a celebration for the return of the White Yaksha. Katsura then introduces a new leader-in-training "Sho-chan". The rebels recognize that the new leader is in fact Tokugawa Shige Shige.
Katsura sets up a series of games: Jenga, Reversi, and Uno, to train "Sho-chan" about the ways of a leader only to lose in all three games handedly. The Joi rebels are impressed by his nobility and abandon Katsura. A depressed Katsura leaves to free Gintoki with everyone ignoring him, but ends up begging Gintoki for help.
Prison guards show up but Sho-chan and the Jouishishi save them and are planning to raid the building. Katsura and Sho-chan decide that it would be easier to go for the head of Tokugawa Soyo to prove who was the better leader. Inside the Hime's room Gintoki is surprised to see both the Jouis and the palace guards pointing their swords at the Shogun and Katsura respectively. The two admit that they had realized who they were and were also testing each other. Both state that they just wanted to see what the enemy commander was like and Shige Shige lets Katsura, Gintoki and the Jouishishi go free. They both promise that if one of them dies, then the other will try to make Edo and Japan a better place.
