Now, Takeru Shiba, the youngest head of the Shiba Clan must gather his four vassals in order to battle the Gedoushu under the revived Doukoku Chimatsuri as the Shinkengers. However, as they are joined by his childhood friend Genta, the vassals slowly learn that there's a reason for Takeru's behavior that sets him apart from his predecessors.
