Takeru Shiba, the 18th head of the Shiba Clan, must gather together his four retainers to become Shinkenger to face against the return of the Gedoushu and their leader, Dokoku Chimatsuri.

Takeru's new retainers show difficulties in adjusting to their new lives as Shinkenger as another Ayakashi attack forces them to learn the rules of their master.

Ryunosuke is sent to catch the Marlin Origami living in the wild, where he must work with a jaded fisherman to save his team from a poisonous Ayakashi.

When brides are being abducted for Dayuu Usukawa's selfish desire, Mako goes undercover to help the team track them down.

When a dream-making Ayakashi attacks the city, Mako becomes trapped within where she witnesses Dayuu's horrifying origin.

Takeru is forced into having a showdown with Juzo Fuwa, but Ryunosuke stands alone in trying to stop his lord from going through with this selfish decision.

The Shinkenger are recruited by a nurse to save a sickly child held hostage by the remains of Manpuku Aburame's forces.

A boy from the birthplace of Origami comes to the Shinkenger hoping to give them the Ushi Origami, an Origami infamous for rampaging in the past.

With the Ushi Origami running amuck and Hiro trapped inside, the Shinkenger must work with his grandfather to figure a way to stop the rampage and prevent Happouzu from taking control of it for Akumaro.

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 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.
