OOO · Den-O · All Knights Let s Go Kamen Rider

On a not peaceful day, Hino Eiji (Hideo Watanabe), who transformed into Kamen Rider OOO, teamed up with his partner Ankh (Ryosuke Miura) to fight Shuka. Unexpectedly, at the critical moment, an accident occurred in the battle situation, and a space-time train DenLiner unexpectedly appeared in front of the two. They were surprised when they saw Kotaro (Michi Sakurada) who could transform into Kamen Rider Den-O. The two took advantage of the chaos to board the train, but the conductor strictly prohibited them from getting off, lest they disrupt the direction of history. The train went back to 1971, when Kamen Rider Den-O and the strange devil started a duel to the death.

When they returned to their own era, they found that the whole world had been turned upside down. Shuka was stronger than ever and almost ruled the world. Unwilling to admit defeat, Eiji and Ankh started a battle with Shuka...
