Kamen Rider Zi-O

Sougo and Geiz face a new Another Rider who can return all attacks against it with two times the power and their investigation on the enemy leads them to meet Daisuke Okubo, chief editor of the ORE Journal.

Sougo confronts a mirror version of himself, while Geiz looks for a way to destroy Another Ryuga and rescue him.

The defeated Another Riders begin reappearing and attack the people who they manifested from their contracts with the Time Jackers. Sougo investigates, but encounters a new enemy in the form of a vaguely familiar face who is masterminding the Another Riders' attacks and can transform into Another Rider with similar powers to Zi-O.

Tsukuyomi travels to the past to discover the connection between Sougo and Another Zi-O, while Geiz decides to finally put the new power he gained from White Woz to use.

Geiz reaffirms his intention to stop Sougo from becoming Oma Zi-O, but Woz allies himself with Heure to intervene in the fight between the two Kamen Riders.

Hiryū and Black Woz, as Kamen Rider Woz, confront Sougo and Geiz, respectively. The two riders however, are determined to overcome all obstacles and confront each other in their destined fight.

Sougo has finally made peace with Geiz and Tsukuyomi, but they have little time to celebrate as a new Another Rider, as well as other Kamen Riders from the past, appear before them.

With the forced battle between Kamen Riders Blade and Chalice threatening all life on Earth, White Woz appears before Geiz with the Zi-O II Ridewatch, the Geiz Revive Ridewatch, and a solution to this crisis.

Woz struggles to figure out how to properly celebrate Sougo's upcoming birthday as Another Hibiki attacks with Todoroki and the current holder of the Hibiki title dealing with the Another Rider themselves.

As Sougo's birthday arrives, he appproaches Kiriya Kyousosuke for Kamen Rider Hibiki's powers, but the latter reveals that he had never truly surpassed his teacher.

A lawyer visiting Kujigojidō is attacked by Another Kiva, Sougo's childhood crush who seeks to become "queen" of the world. Just then, an new enemy named Kamen Rider Ginga enters the fray to destroy the world.

Finally aware of who Another Kiva is, Sougo approaches her in an attempt to make amends just as the Time Jackers try to form an alliance with her to stop Kamen Rider Ginga. Meanwhile, Geiz travels to the year 2015 to find out what really happened to Sougo's first love.

Meteorites starting falling all over the city, and release Worms that start attacking; with Another Kabuto and the Hopper Brothers apparently leading them. To combat them, the Time Riders have to locate Kamen Rider Gatack just as Tsukasa returns with the revelation that Tsukuyomi has had something to do with this crisis.

After destroying the meteorite, the Time Riders learn that an even larger one is on the way with Sougo and Woz attempting to destroy it despite Another Kabuto's attempts to stop them. Meanwhile, Tsukasa leads Tsukuyomi to a strange house so she can learn a shocking truth.

As Kujigojidō receives a surprise visit from the Taros Imagin when they need Junichirō Tokiwa to repair the DenLiner, the Time Riders find themselves dealing with Kamen Rider Zeronos and a new Another Den-O.

Though Sougo acquired the Grand Zi-O Ridewatch, it disappeared as the result of Yuto's meddling with the timeline. The Time Riders realize that Another Den-O made a contract with the Mole Imagin as they and the DenLiner crew join forces to reclaim the stolen DenLiner from Another Den-O while Sougo ends up having another encounter with Oma Zi-O.

Sougo and Oma Zi-O have their climatic rematch when a temporal distortion returns the former to 2019. There, Sougo finds his timeline has been greatly altered with his granduncle not knowing who he is, Geiz and Tsukuyomi seeing him as their enemy again, and Woz now serving Hiryu who has took over Oma Zi-O's place as the tyrant king as the Another Rider Another Zi-O II

Geiz attacks Sougo, even in spite of the latter's refusal to fight his friend. Just then, Tsukasa returns to seemingly aid them. Meanwhile, Daiki Kaito approaches Hiryū and Woz to claim their "treasure"

With Tsukuyomi captured, Schwarz begins to reveal the story behind her amnesia as well as his plan, which sends Heure and Ora running; forcing them to seek out the Time Riders as they and Tsukasa join forces to confront Another Zi-O II and his army of Another Riders in a epic showdown.

As the Time Riders investigate the disappearance of a former classmate of Sougo's, they encounter Michal Minato/Kamen Rider Aqua, who has come from 2050 to take Tsukuyomi and Geiz back to their time for unknown reasons. However, while fighting Another Drive, the group are confronted by Swartz, who reveals his new power as Another Decade while he's gathering the Another Riders' power for himself.

With Another Drive's identity supposedly revealed, Geiz argues with Sougo over both trusting Heure and Ora while questioning if he has any right to remain in the present. Meanwhile, Swartz recruits Kamen Rider Eternal to his side after spiriting Sougo's classmate Kowada away.

Geiz becomes trapped in Swartz's Another World, with a revived White Woz taking his place to confront Black Woz. Meanwhile, Swartz's plan nears completion, but Michal Minato stands against him with the last of the courage that Kamen Rider OOO gave him.

Strange occurences happen all over Japan, from a strange wall dividing the country to Sougo's Ridewatches mysteriously losing their power. With Tsukasa's powers, Tsukuyomi takes Sougo to her original timeline to investigate as an army of Roidmudes led by Mashin Chaser stand in their way.

As Earth is subjected to a mass convergence with the A.R. Worlds and his friends continue to fight Swartz and the influx of past monsters, Sougo realizes he is the epicenter of the chaos and travels to 2068 to settle things with Oma Zi-O in a final confrontation.

Tsukuyomi has became a Kamen Rider, only to betray everyone and advance the A.R World apocalypse. After Geiz is killed attempting to stop Tsukuyomi, a disturbingly calm Sougo resolves to end Schwartz's scheme and stop his former friend by becoming Oma Zi-O as the final battle reaches its conclusion.
