Beginning: Fight! Legendary Seven Riders
Meteorites fall from space all over the world, carrying a mysterious substance called SOLU. As Kamen Riders 1, 2, V3, and Riderman battle Dustards and Waste Yummy in Europe, Kamen Riders Amazon and X fend off Masquerade Dopants in Chile. In the Middle East, holding off all three grunt types, Kamen Rider Stronger fails to stop Foundation X from retrieving the SOLU. In Japan, Foundation X agent Lem Kannagi reports his progress to Chancellor Kiima and proceeds in the next phase of his plan.
OOO: Ankh's Resurrection, the Medals of the Future, and the Leading Hope
One of meteorites causes a time hole to open in Japan as a bloodthirsty Kamen Rider from 40 years in the future emerges to fight this era's Kamen Riders. As Kousei Kougami informs Shintaro Gotou of the event, giving him the Birth Driver while revealing to have been researching the means to recreate the Core Medals, Erika Satonaka informs Hina Izumi as they make their way to the airport to meet Eiji Hino. However, the ladies are attacked by Waste Yummy with Satonaka attempting to fight them off with the Birth Buster before Eiji arrives to save Hina in the nick of time. However, the mysterious Kamen Rider appears and knocks him out as Akira Date arrives and becomes Kamen Rider Birth Proto Type to fight the enemy Kamen Rider before Shintaro arrives and joins the fight as Kamen Rider Birth. The two Kamen Rider Births are easily overpowered with Date's Birth Driver damaged beyond repair. However, "Eiji", revealed to be the Greeed Ankh, manages to rip out some of the Core Medals from inside the Kamen Rider as the real Eiji arrives, becoming Kamen Rider OOO and assumes the Random Combos Gatatoradol and Gatagoritar to weaken the enemy. But upon realizing something is off, Kamen Rider OOO hesitates as the enemy Kamen Rider escapes.
Soon after, Ankh resumes his usual form, with Date and Shintaro hospitalized, the gang go to the Cous Coussier where the Greeed refuses to explain the circumstance of his return while Eiji reveals that the Kamen Rider may not be acting of his free will due to the Core Medals inside him. But suddenly, several Waste Yummy burst into the Cous Coussier and Eiji and Ankh hold the homunculi off while Hina and Chiyoko Shiraishi get everyone else to safety. Once done, the two encounter the mysterious Kamen Rider. Though Ankh tells him it is a lost cause, Eiji refuses not give up reaching the Kamen Rider and almost dies if it were not for the youth behind the Kamen Rider managing to restrain himself. As Eiji learns that his name is Michal Minato, the youth reveals himself to be the Kamen Rider for 40 years in the future. However, his fear of water made him unable to use the Kamen Rider Aqua system he was granted and he instead uses a Core Medal system created by Kougami to become Kamen Rider Poseidon. Unfortunately, the Core Medals and remains of Kiyoto Maki emerge from a manifested black hole and enter Michal's body, giving Kamen Rider Poseidon a will of his own.
Waiting Kamen Rider Poseidon out, Ankh attempts to rip the Core Medals out from the Kamen Rider before the entity leaves Michal's body and decides to fight the Kamen Riders in another time period. Kougami warns Eiji that he does not stand a chance, but he does not believe Kougami, and gives Michal a pair of boxers and tells him to do what he can today in order to see tomorrow. Arriving at the location of the time hole just as Kamen Rider Poseidon is about to leave, as Ankh holds some Waste Yummy off, Eiji becomes Kamen Rider OOO to fight Kamen Rider Poseidon with Date, Shintaro, and Satonaka providing back up. Managing to face his phobia of water, Michal joins the fight as Kamen Rider Aqua to face Poseidon on the water before taking their battle to the land. Assuming Tajadol Combo, Kamen Riders OOO and Aqua combine their signature attacks to destroy Kamen Rider Poseidon. After Kamen Rider Aqua leaves, Ankh is nowhere to be seen as Eiji reveals to Hina that Ankh actually came from the future, giving him hope that he will somehow revive their friend. However, the two are caught off guard by an explosion as Kannagi retrieves Poseidon's Core Medals.

In Futo, Shotaro Hidari chases after a Foundation X convoy before managing to stop it. As Philip is preoccupied, Shotaro decides to become Kamen Rider Joker to destroy the Kamakiri and Kabuto Yummy. By then, Kannagi and his two aides arrive to a secret airport to enter their spacecraft the Exodus and install Kamen Rider Poseidon's Core Medals into a Driver before the Seven Riders arrive. After disposing of the interlopers, Kannagi states that only the SOLU is needed. However, Kamen Rider Joker's interference causes the SOLU sample to leak into the sewer.

At Amanogawa High School, they are hosting a cultural festival where Gentaro Kisaragi gets his fortune told by Mr. Chuta Ohsugi before the Kamen Rider Club, consisting of Gentaro and his friends space nerd Yuki Jojima, budding scientist Kengo Utahoshi, football team captain Shun Daimonji, cheerleader Miu Kazashiro, and goth Tomoko Nozama, begins its dedication to the past Kamen Riders. However, other than social butterfly JK being a no show, a mysterious girl falls from the sky as Gentaro saves her and they take her to the hospital. The Kamen Rider Club learns her name to be Nadeshiko Misaki from Subaruboshi High School before the group is attacked by Dustards. Realizing that the Dustards are after her, Gentaro protects Nadeshiko from them before he transforms into Kamen Rider Fourze to fight just as Nadeshiko suddenly transforms into Kamen Rider Nadeshiko to help take out the Dustards. Soon after, the Virgo Zodiarts arrives to demand Nadeshiko Misaki from Kamen Rider Fourze as he assumes Elek States to fight the Horoscopes. Deciding to change back into Base States, Kamen Riders Fourze and Nadeshiko execute a Double Rider Rocket Punch to force the Virgo Zodiarts to fall back. After, the Kamen Rider Club learns that Gentaro is in love with Nadeshiko. Spiriting Gentaro off before she can answer Kengo's questions of where she obtained her Kamen Rider system from, Nadeshiko starts to become more vocal as she and Gentaro become closer before he takes her to the Rabbit Hatch. When Nadeshiko takes off her space helmet to kiss him, Gentaro realizes that she is not human.
Kengo reveals that she is one of the Seeds Of Life from the Universe, or "SOLU", an alien lifeform that mimics what it sees. Though Kengo explains that a SOLU is unable to be truly conscious, Gentaro refuses to accept it as he runs off. After Yuki manages to cheer him up, Gentaro refuses to let Nadeshiko go as he takes the container holding her from Foundation X posing as college scientists. Touched by Gentaro's feelings for her as she emerges from the container, Nadeshiko hugs him out of gratitude before Foundation X decides to take Nadeshiko by force as Kamen Rider Fourze chases after them on the Massigler before forced to fight Katal as he mutates into the Mutamit Suddendath. After Shun uses the Powerdizer to help in the fight, Nadeshiko becomes Kamen Rider Nadeshiko to fight Foundation X's Masquerade Dopants before joining Kamen Rider Fourze in defeating Suddendath. After Kamen Rider Fourze accepts that she is not real but he still loves her, Nadeshiko is captured by Kannagi who converts her into the SOLU Switch much to Gentaro's horror. After defeating Gentaro, Kannagi leaves the boy at Suddendath's mercy as the rest of the Kamen Rider Club holds the Mutamit off. Touched by his friends' actions, Gentaro transforms into Kamen Rider Fourze, again, and assumes Fire States before finding Nadeshiko's Rocket Switch Super-1, using it to become Kamen Rider Fourze Rocket States to destroy Suddendath. Soon after, the Kamen Rider Club meets Eiji as he asks for Gentaro's help in defeating Foundation X.

However, Kannagi sends his remaining aide Solaris to finish the Kamen Riders off by becoming the Unicorn Zodiarts while her followers become the Orion, Chameleon, and Hound Zodiarts. To return the favor to Eiji for before, Shotaro and Philip become Kamen Rider Double to hold off the Foundation X Zodiarts as Eiji and Gentaro assume their Kamen Rider forms to reach Kannagi. Amused at the Kamen Riders' intent to stop him, Kannagi puts them at the mercy of an army of Dustards, Waste Yummy, and Masquerade Dopants. As Kamen Rider OOO assumes his various Combos to take out some of the grunts, Kamen Rider Fourze uses his Astroswitch combinations to wipe out the rest before the Exodus begins takeoff. As Kamen Rider OOO is overpowered by replicas of the Greeed and the Museum Dopants, Kamen Rider Fourze reveals he has found four Kamen Rider themed Astroswitches and three Kamen Rider themed Core Medals. When the two Riders use the items, they are revealed to be the Seven Legendary Kamen Riders and are able to return to their normal forms. They tell the two Kamen Riders to stop Kannagi while they hold off the monster replicas as Kamen Rider Aqua arrives to give Kamen Rider OOO a new set of Core Medals from the future.
