Closing Act: The Samurai Sentai is Eternal

The Samurai Squadron is Eternal is the forty-ninth and final episode of Samurai Sentai Shinkenger.

Plot
As the Shinkengers battle thousands of Nanashi Companymen, Doukoku decides to break the Shinkengers' fighting spirit. While Shinken Gold and the vassals hold off the Gedoushu forces, Shinken Red attempts to use the Shiba House Disk on Doukoku. But Doukoku resists and becomes enraged that they refuse to show weakness to him. He then leaves the battle to attack and kill Kaoru directly. Jii arrives to hold off the Nanashi Company, allowing the Shinkengers to recover and defeat them. Leaving DaiGoyou with Jii, the Shinkengers chase after Doukoku. They encounter Tanba, who gives them another Shiba House Disk, which Kaoru risked her well being to create, along with his own Twin Disk. Shinken Red uses the Twin Disk to summon a second Rekka Daizantou, and the Shinkengers manage to overpower Doukoku as Shinken Blue uses the Shiba House Disk to deliver the deathblow. Assuming his second life, an enlarged Doukoku overpowers the Shinkengers in Samuraihaoh. Under Takeru's guidance, Samuraihaoh charges Doukoku head-on, as he breaks off the Origami combinations until only Shinkenoh remains. The Shinkengers use all their Modikara in one final attack, successfully destroying Doukoku for good. With Doukoku's demise, the Sanzu River withdraws from the mortal realm as Shitari goes down with the Rokumon Junk. Later, after Kaoru leaves him with the task of continuing the Shiba House's fight against the Gedoushu, Takeru bids farewell to his friends: Genta heads to Paris to make a name for himself in the cooking world; Kotoha returns home to Kyoto to take care of her sister; Chiaki leaves for college; Mako goes to live with her parents in Hawaii; and Ryunosuke resumes his kabuki career. Until the Gedoushu resurface, Takeru will remain on watch for them while Jii attempts to give his lord a hobby outside of being a samurai.
