With the Sanzu River overflowing and Gedoshu rampaging through the human world, Takeru, his five retainers and allies must work together and use everything to finally put a stop to Dokoku and restore peace once again.
Takeru completes his final showdown with Juzo Fuwa while finally confronting his retainers about the deception as Dayu prepares the final step for Dokoku's return.
As Dokoku returns with Dayu's sacrifice, Kaoru and the retainers desperately attempt to seal him once and for all while Takeru becomes involved in a stunning move by the Shiba head.
With no other purpose left, Takeru begins his climactic showdown with Juzo, while Hikoma tries to find him to remind him of the bonds he still possesses.
As Kaoru takes her place as the true Shiba Clan head, Takeru is forced to figure out where to go next while his former retainers are forced to adapt to their new leader.
As the other Shinkenger relax, Takeru trains in increasing his Mojikara in order to use a beetle-themed Secret Disk, which becomes necessary against an Ayakashi their swords can't cut.
The Shinkenger learn the truth regarding Doukoku's previous defeat and his hatred for the Shiba Clan as he sends out his most powerful Ayakashi while both are intercepted by the eye of Juzo Fuwa.
