Suddenly, he meets a mysterious girl hailing from the year 2068, named Tsukuyomi, who comes with an ominous warning: Sougo will become Ohma Zi-O, the tyrannical Overlord of Time.

He is aided in his quest by Geiz Myokoin, a resistance fighter also from 2068 capable of becoming Kamen Rider Geiz who initially intended to kill Sougo to prevent his future tyranny, and a self-titled prophet named Woz, who wants the youth to become the tyrant Ohma Zi-O, who later gains the power to become Kamen Rider Woz.

Along their journey, Sougo and his friends meet several Kamen Riders from the past and their allies; earning their trust and obtaining their powers.

Following his high school graduation, Sougo discovers that Swartz, the Time Jackers' leader, is Tsukuyomi's older brother and was manipulating both the Riders and his fellow Jackers in his plan to fuse the entirety of the Kamen Rider multiverse into a single, unified world to destroy it and save his world.

Despite their best efforts, Sougo and his allies fail to stop Swartz until the former accepts his destiny and becomes Ohma Zi-O to destroy him.

However, instead of taking control of the world as foretold of him, Sougo renounces his powers to undo Swartz's damage; creating a new reality where he lives in peace with Geiz, Tsukuyomi, and the other Time Jackers.
