Act 40: The Honorable Leader Heads to the Front Lines

The Honorable Leader Heads to the Front Lines is the fortieth episode of Samurai Sentai Shinkenger.

Plot
While training, Takeru almost hurts Chiaki while remembering Juzo's words from their last encounter. While this occurs, Doukoku has Shitari demand Dayu's shamisen from Akumaro. Akumaro takes Shitari to where he placed the instrument and then attacks him, revealing that he had allied himself with Doukoku as part of his plans. This causes Shitari to fall back and cause the Gap Sensor to detect his movement. Sensing her shamisen's cries, Dayu makes her way to Akumaro's location just as the Shinkengers arrive to fight him and are outmatched. Using the shamisen as a shield, Akumaro overpowers Dayu until an enraged Doukoku arrives in the mortal world to kill him and the Shinkengers even if he dies in the process from rapid dehydration. Akumaro loses the shamisen and escapes, leaving the Shinkengers to fight Doukoku. Super Shinken Red summons the Mougyu Bazooka to attack Doukoku, but the Gedoushu resists the attack long enough to defeat Super Shinken Red. After repairing Dayu's shamisen, the nearly dead Doukoku is dragged back into the realm of the dead by Shitari, who leaves an Ōnanashi Ōzutsu Squad to finish off the Shinkengers. Shinken Yellow tends to Takeru's wounds, leaving Super Shinken Blue in Daikai-Shinkenoh and Shinken Gold in Mougyudaioh to defeat the Ōnanashi. As a near-death Takeru is taken to the Shiba House, Doukoku is dropped into the depths the Sanzu River to regain his strength, leaving Akumaro to take over the Rokumon Junk with no opposition.
