At the Sword of Logos' Agastya Base space station, the guardian Asmodeus rebels and takes control of all the books containing the Kamen Riders and Super Sentai's stories, merging them into one story. Meanwhile, Touma Kamiyama, Mei Sudo, and Yuri are transported to the world of Kikai Sentai Zenkaiger while Zenkaiger members Kaito Goshikida, Gaon, Magine, and Vroon are transported to the world of Kamen Rider Saber.
Kamiyama's group encounter Juran while he is searching for his teammates, help him repel one of Tozitend's attacks, and meet a young boy called Shotaro.
Suddenly, Asmodeus uses his powers to send Goshikida and Rintaro Shindo to a world based on Journey to the West and Kamiyama, Juran, Sudo, and Shotaro to one based on Nansō Satomi Hakkenden.
However, he convinces Shotaro that both the Riders and Sentai groups should not exist as they always suffer over the course of their stories. Shotaro destroys his drawings, causing the Riders and Sentai to disappear.
Realizing that facing hardships is what makes heroes human and that Shotaro is actually a young, time-displaced Shotaro Ishinomori, the creator of the Riders and Sentai's stories, Kamiyama finds and convinces him to create heroes again.
Concurrently, Asmodeus joins forces with the Riders and Sentai groups' enemies to take over the story worlds, only to be opposed by the Sword of Logos, Zenkaigers, Twokaizer, and their Rider and Sentai predecessors, who destroy the villains while Asmodeus is defeated by Kamen Riders Revi and Vice.
As the heroes return to their respective worlds, Kamen Rider 1 recognizes Shotaro as his creator. Though the latter realizes he is at a point in time where he is already dead, he rejoices knowing that his creations will continue inspiring others long after his death and promises to fulfill his dream of making hero stories before returning to his time.
