Kamen Rider OOO Wonderful: The Shogun and the 21 Core Medals

Synopsis

While leading an expedition in Thuringia, Germany, Kousei Kougami and Erika Satonaka unearth the tomb of an alchemist named Gara. With the seal broken, Gara uses his magic to revive himself, capture Kougami and Satonaka, raise a tower protected by a magical barrier, and transport it to Japan. Eiji Hino, Ankh, and Akira Date investigate and battle knights emerging from the tower. Their fight attracts the Greeed and Gara, who steals most of the combatants' Core Medals and attempts to kill a young boy named Shun Wakaba. After Eiji rescues Shun, Gara announces his intention to become the ruler of a new world before Shintaro Goto arrives and reveals who Gara is. Ankh senses a being similar to Gara and leads the group to a girl named Bell, who is amassing human desire to power Gara's doomsday machine.

As the machine activates, Eiji, Hina Izumi, and several civilians are transported to the Edo period. He attempts to keep the peace between the present and past individuals until the Nue Yummy attacks him. Eiji borrows Date's Rider equipment after losing his, before partially regaining his equipment and escaping with Hina. As Tokugawa Yoshimune dispels rumors about Eiji, Shun reveals to the latter his mother, Satsuki, was kidnapped and possessed by Gara. Meanwhile, Kougami convinces Gara to use Eiji's infinite desire to accelerate his plot.

The next day, Eiji fights the Nue Yummy again, but is overpowered until Hina, Yoshimune, and the Edo civilians help him destroy it. Bell appears before Eiji and offers him the choice of returning to his time while everyone else is erased from existence. He agrees on the condition that he be allowed to bring his family with him. Bell grants his wish, but realizes too late that he considers everyone in the world his family. Gara's machine is overloaded while the displaced individuals are returned to their proper time periods.

After Date and Goto destroy the barrier protecting it, Eiji and Shun storm Gara's tower. As Kougami and Satonaka secretly break out, Gara assumes his true monstrous form to battle Eiji. Shun's presence allows Eiji to free Satsuki before the fight is interrupted by a crash-landing Kamen Rider Fourze, who befriends Eiji before the pair knock Gara into his tower. As Fourze leaves to return to school on time, Gara transforms into a dragon and overpowers Eiji and Date until the Greeed give Eiji their remaining Core Medals so he can destroy Gara with Date's help.
