* Kamen Rider Gaim has four arcs. Each focusing on a different antagonist. The first arc had rival dance teams (1-11), the second arc dealt with the Mega-Corp (12-23), the third arc introduced the rulers of the central antagonist (24-32) and the final arc is an all-out war (33-47).

* Kamen Rider Ex-Aid also has four arcs. The first arc is about the effort of the Riders to complete and gain the original 10 Gashats and the secret surrounding the mysterious "Black Ex-Aid" (1-12). The second arc focuses on the secret to the main character's immunity to the Bugster Virus and the arc villain's master plan (13-24). The third arc has the heroes dealing with a Deadly Game that the villains has unleashed upon humanity (25-40). The final arc has the main characters and former foes joining forces to finally defeat the Big Bad(41-45).

* Kamen Rider Build has three arcs. The first arc introduces settings, main characters and the mysterious evil organizations they fight against (1-16). The second arc has the civil war between the three regions of Japan and the toll it takes on the main characters (17-28). The final arc finally reveals the Big Bad, secrets about the main characters and the people close to them and the final battle against said Big Bad, with even former foes joining the heroes for the fight (29-49).

* Kamen Rider Zi-O has four arcs. The first arc introduces the characters and has the mysterious group of time travelers erase the past history of previous Kamen Riders while showing tribute to Build, Ex-Aid, Fourze, Faiz, Wizard, OOO, Gaim, Ghost, and Decade (1-16). The second arc involves the alternate version of a main character coming from a timeline where the Evil Overlord was defeated while paying tribute to Ryuki and Blade (17-30). The third deals with the fallout of the multiple Time Paradox as well as learning more about the female lead's past as well as tributes to Agito, Hibiki, Kiva, Kabuto, and Den-O (31-40). The final arc reveals the motivation of the Big Bad and how the heroes must fix the time distortion before their universe is destroyed and showing tributes to W and Drive as well as the Movie Riders (41-49).

Look like Zero-One is continuing the trend of multiple arc show with 2 arc so far.
