Haruto finds a group of humans who resemble his friends that cannot change into monsters, who are protecting a chest they stole from Amadum that contains the Rider Rings. The alternate Haruto and Koyomi of this world use these rings to summon the 13 Heisei Kamen Riders to protect themselves from Amadum's forces so that they can leave this world. A Kosuke from the past arrives in this universe to aid Haruto, as he got sucked in as well. Amadum plans to use the rings to break free from the Magic Stone and unleash an army of monsters upon the world. During a battle between the Kamen Riders and the monsters, the children open a portal to Earth. Their cries for help are heard in Zawame City by Kouta Kazuraba, who leaps into the portal to The Magic Stone and transforms into the newest Kamen Rider, Gaim.

Amadum then tries to use the Rings to destroy Haruto, but the Kamen Riders refuse to obey him. Tsukasa transforms into Decade and fights alongside Haruto and the other riders destroying Amadum's forces. Amadum uses his power to steal their abilities and nearly defeats them, but the alternate Haruto summons Kouta back as Gaim. Wizard tells Gaim what it means to be a Kamen Rider like his predecessor before him and Kouta officially adopts the moniker. The Kamen Riders get their powers back and change into their strongest forms. All 15 of them then use their respective Rider Kicks and then Gaim and Wizard slash Amadum, destroying him.

He also told Zack that he can use the Energy Lockseed by using a Genesis Core from the Genesis Driver, which Zack notes that he can't use the Energy Lockseed since Kaito's Genesis Driver was already damaged by Ryoma's self-destruct mechanism.
- Peko, after leaving Neo Baron, meets Zack and told him that he was forced to join Neo Baron as he couldn't forgive Shura's sins for using Team Baron's name for evil purposes. Zack forgives him and told Peko to do something for him, which is later revealed to check if the Genesis Core from Kaito's Genesis Driver is still usable.
- Zack confronts Shura, and found out that Shura has a Lockseed on his own, which enabled him to transform as Armored Rider Black Baron. Zack fights him as Knuckle, with him gaining the upper hand until Shura sends the Kurokage Troopers at him. Defeated, Peko then appears to give Zack a Genesis Core, finding out that the Genesis Core from Kaito's Genesis Driver is not affected by Ryoma's self-destruct mechanism.

Becoming Kamen Rider Ex-Aid for the first time, Emu saves a young boy from the Salty Bugster whom had plagued him.
- Heeding the request of Kuroto Dan, Emu participates in a VR simulation at CR to record his specs in the Action Gamer.
- Hiiro Kagami joins CR, using his Taddle Quest Gashat to become Kamen Rider Brave. A genius surgeon who takes issue with the pediatric intern Emu, Hiiro proves his effectiveness as he terminates the Aranbura Bugster plaguing Rensuke Natori.
- Having purchased a new Gamer Driver and Bang Bang Shooting Gashat from Dan, Taiga Hanaya re-emerges and makes a with Emu to take down the Revol Bugster. Prevailing against the Bugster as Kamen Rider Snipe, Taiga takes the Mighty Action X Gashat from Emu who is at least happy that the paitent has been saved.
- Blackmailing Dan, Taiga receives data from his own specs having undergone a simulation to assess Bang Bang Shooting.

- After his successive defeats at the hands of Kamen Rider Genm, Hiiro fights a simulated Genm at CR. Though prevailing, Hiiro, realizing that Dan had set the difficulty to Easy, is disatisfied knowing the real Genm is much stronger.
- Alerted by Dan to four Rider Gashats which have been stolen from Genm Corp., the Kamen Riders discover the thief, who is later found out to be the human form of the Bugster executive Graphite, while finding a Bugster using the power of the Gekitotsu Robots Gashat.

Brave, defeating this Bugster himself, claims the Beat Gamer to access his own Level 3 which allows him to fight back against Graphite.
- Taking a simulation of his own, Dan defeats Graphite who enroached on the simulation to test himself. Satisfied at his performance as Kamen Rider Genm, Dan is assured that no-one can stop him.

Managing to take out one of the Bugsters, Ex-Aid gives the recovered Giri Giri Chambara Gashat to Lazer. Though accessing his own Level 3 Gamer, Kiriya is unable to convince Emu and Kagami that Kamen Rider Genm is Kuroto Dan as the Bugster executive Parad appears before them instead before secretly spiriting Dan away.
- Finding and disarming the remaining Bugster attacking Okada's factory, Snipe chooses to spare the Bugster, endangering the paitent, in a bid to claim the Level 3 Gashats of Ex-Aid and Brave. Though the Bugster is ultimately destroyed, Snipe succeedes in taking the Gashats in addition to the Combat Gamer he now possesses.
- Having taken the Proto Drago Knight Hunter Z, Graphite's form evolves as he infects Kyotaro Hinata and numerous civilians with an especially potent Bugster Virus. Dan, having allowed Graphite to take the Proto Gashat, gives the refined albeit incomplete Drago Knight Hunter Z to Emu, which he unlocks by freeing the Hunter Gamer from the dragon Bugster within Hinata. While accessing Level 5 for the first time enables him to match Dark Graphite's power, Ex-Aid finds the Full Dragon mode unable to sustain as its power overwhelms him.
- Taking on the power of his three rival Kamen Riders, Ex-Aid is able to lead them in a final battle to take down Graphite. Dividing the Hunter Gamer, the four Kamen Riders briefly work together and succeed and destroying Dark Graphite, thus curing Hinata and his other victims. However, this was all part of Dan's plan. Collecting all the data he needs, Dan proceeds to the next stage having completed "Phase One".
- Through recording the past Kamen Riders, Dan, aspiring to gather the power of Legends, creates a set of Legend Rider Gashats. Using Ex-Aid as a pawn to finish collecting data on the Gashats by pitting him against a Collabos Bugster, Genm finalizes a Ganbarizing Gashat through their power only to be interrupted by the shock return of Dr. Pac-Man who presents his own three Bandai Namco Gashats.
- Escaping with Emu, "Dr. Pac-Man" hands his Gashats to him along with Hiiro and Taiga, granting them new Gamers which allow them to defeat a trio of Kamen Riders manifested by Genm using Ganbarizing. Caught and unmasked by Genm, "Dr. Pac-Man" presents a fourth Gashat, Taiko no Tatsujin.
- Confronting Kamen Rider Genm with their co-operative Level 5, the four Kamen Riders manage to defeat him with Ex-Aid claiming his Shakariki Sports Gashat, thus clearing all ten of Genm Corp.'s games. However, having used the data of his own "death" in the Gashacon Bugvisor to revive and complete a new game, Dangerous Zombie, Dan drops the charade as he reveals himself to the Kamen Riders, with the others realizing that Kiriya was right all along.
- December 25th: Saving a young boy from an evolved Salty, Emu realizes that the Bugster virus is evolving. Meeting Kuroto Dan in a final confrontation, Kiriya Kujo is killed in action by the latter's Zombie Gamer Level X. While Lazer's Gashacon Sparrow is taken by Dan, Emu inherits Kiriya's Gashats and Gamer Driver as he along with Asuna, Hiiro, and Taiga find Kiriya in his last moments.
- Emu begins his surgical internship under Hiiro's wing (much to the latter's dismay). CR's next patient is surgeon Kazuki Shirakawa, who is infected with Aranbura. Genm interrupts the operation to steal Ex-Aid and Brave's Gashats. Emu has his Gashats taken by Hiiro after the former loses control and attacks Genm in the middle of the operation. Hiiro is attacked by Aranbura, with Genm and Snipe joining in soon after. Simulateously, Parad confronts Emu outside the hospital, giving him a blank Gashat and advising him to use it against Genm.
- In the confusion caused by Ex-Aid becoming two separate riders, Genm and Aranbura escape.
- Nico Saiba attempts to become Kamen Rider Snipe to defeat Emu but instead recreated the Revol Bugster, who is now at Level 5, thus giving her the Game Disease.

2024 (Potential Future)
- Had the heroes of Earth failed to defeat the Inves, the Helheim Forest would have taken over the world and six billion people would either be infected and become Inves themselves or culled off to ensure Project Ark's success.
