The show’s Twitter page revealed the show will enter a new arc with this week’s episode.
Kamen Rider Zi-O will enter the “Oma Zi-O” arc beginning with the show’s 15th episode, “Back to 2068”. Within the series, Oma Zi-O is the future form of the show’s main character, Sougo Tokiwa, who has become the demon king who rules the future.
Up to now, the show has focused on Sougo interacting with past Kamen Riders, gaining their powers in the form of armors to be used in battle. The Oma Zi-O arc will see Sougo deal more directly with the problem of his impending future as the evil ruler of Earth.
