Youkai Buruburu attacks several civilians and causes them to subject their fears. Kyuemon gathers a lot of human fears and praises a silver-haired man for his help. The Ninningers transform and fight the Youkai, but are overpowered by its ability to induce a strange wave that decelerates their movements as he overpowers them and takes his leave. The Ninningers however are attacked by a strange red car, revealing Kamen Rider Drive who addresses the Ninningers as “colorful Roidmudes” before attacking them as Type Speed Shadow and Type Technic. AkaNinger quickly breaks the fight and tries to reason with Drive to prove that they are not the Roidmudes, as well as the earlier incident. Gou captures a photo of a strange phenomenon in the sky, sensing that something huge is about to happen. Eventually, Drive un-transforms and handcuffs AkaNinger before realizing that the others have disappeared.
At the Ninjitsu Dojo, the other Ninningers decide to hunt the Youkai first, as Takaharu can solve the matters quickly. While Takaharu (still in his transformed state) is interrogated, Mr. Belt via Shift Speed analyzes his equipment but finds that it it not of this world. Takaharu eventually uses a smokescreen technique to disappear. Kyuemon thanks the Roidmudes for helping him. Brain is disgusted to have his kind being addressed as mechanical puppets by him, but Heart calms him down since they are regarded as “monsters” by humans as well. While Shinnosuke is searching for Takaharu in the department, AkaNinger appears in front of him and tries to prove he was right until they hear an argument from the Special Investigation Unit’s office, where both Yoshitaka and Captain Jun quarrel when they don’t believe each others’ stories.
Just then, the Heavy Acceleration occurs again where the other Ninningers fight Buruburu with Takaharu bringing Shinnosuke to the location. While Gou is capturing photos, Kamen Rider 3 introduces himself and challenges Gou, who proceeds to transform into Mach. Takaharu and Shinnosuke arrive to the spot, but instead witness the other Ninningers shivering in fear and attack Takaharu while seemingly emitting the Heavy Acceleration until Takaharu solves it and reveals the Youkai, gaining Shinnosuke’s trust. He and the other Ninningers regroup and battle Buruburu. When AkaNinger slashes him, Shinnosuke and Mr. Belt witness a Spider Viral Core, wondering what just happened until Kyuemon, the silver-haired man and two other Roidmudes appear. The mysterious man reveals himself as Roidmude 089 and fights Drive alongside his comrades. After the Ninningers destroy Buruburu, the purified Sealing Shuriken is retrieved by Kyuemon, who gives it to 089 while growing 057 and 016 into giant proportions.
057 captures Drive as his hostage, causing the Ninningers to summon their OtomoNin. Brain witnesses the OtomoNin, but is dismissed of it when his comrades don’t see them and think he was hallucinating. Using Shurikenjin, they save Drive before forming Shurikenjin UFO and destroying the two Roidmudes with its Shurikenjin: UFO Big Bang finisher. Suddenly, UFOmaru vanishes where Kyuemon reveals that it has ceased to exist due to being inside the world of Kamen Riders, making the Ninningers realize that they are not inside their own home world. If something older exists in this world, it will quickly vanish, which currently happens to Tsumuji and Yoshitaka. Kyuemon takes his leave, noting to his enemies that they have no alternative to get out. As the police forces arrive to Shurikenjin, the Ninningers are captured and labelled as public enemies
.Mach is defeated by Rider 3, but the latter spares him as he predicts that his life would end soon. After the Ninningers easily escape, Shinnosuke is told that their existence may have caused distortions in his world so much that the Roidmude case has been stepped aside. He witnesses the Ninjutsu Dojo near the office and hears their conversation quietly. In order for them to return, they must find Roidmude 089. Shinnosuke approaches Takaharu at a dock and decides to help him, first by evading police forces. The other Ninningers meet Buruburu, who has somehow recreated himself from the same Sealing Shuriken. The leftover Hitokarage in Drive’s world attack AkaNinger and Shinnosuke until Kiriko rescues them in a minivan. Kiriko shows them the silver-haired man’s photo, which Saijo found on the internet. His name is Doctor D, a researcher from 40 years ago where he died in an explosion in his lab. However, his last words were that he had found the method to rewrite history. Rumours say that his ghost haunted the Eastern Kanto Institue Research of Science.
Shinnosuke, Takaharu, and Kiriko walk into the location and are ambushed by Hiruchameleon before Mach saves them. He searched through the history and reveals that their predecessors, Riders 1 and 2, battled the evil organization Shocker, but there’s no info regarding Rider 3. Witnessing Shocker’s emblem on the photo and comparing it to the ones from Doctor D, as well as as the one from his lab, Shinnosuke has finally solved the case. Just then, the facility is destroyed by Turtle Bazooka. Just as Buruburu, Hitokarage, and Roidmude 076 are about to finish off the remaining Ninningers, the Shift Cars save them as Shinnosuke and the others reveal themselves to be alive thanks to Mr. Belt via Tridoron’s Tire Enhancements. While Buruburu is revealed to be Roidmude 089, the true mastermind however is the Great Leader of Shocker. Speaking through Doctor D’s belt, he confirms that the events were indeed his doings. While Doctor D was supposedly dead, his body cells were saved and used by 089 to become the “reincarnated” Doctor D in order to use his plans. He also fused with the Sealing Shuriken, having Buruburu become his Advanced formIcon-crosswiki. Once the Ninningers and Kamen Riders have transformed, they fight the Shocker armies with AkaNinger destroying Roidmude 076 and Mach eliminating Turtle Bazooka via Mach Mazerl.
Buruburu uses the combined powers of the Youkai, Shocker, and Roidmudes to create the Terrible Pressure attack, which greatly weakens his opponents. Drive and Mach use Shift Formula and Dead Heat respectively to escape, while the Ninningers use their Tower Ninja Whirlwind attack to overpower Buruburu until Drive Type Formula and Deadheat Mach eliminate him, destroying his Core and separating him from the Sealing Shuriken. As 089 is destroyed, UFOmaru is brought back into existence again, as well as Yoshitaka and Tsumuji. After several encouragements, they part ways as the Ninningers vanish via a green aura. Gou realizes that Rider 3 was neither a part of the Anti Shocker Union nor a member of Shocker, which makes him doubt his existence. Kamen Rider 3, with his helmet off, comments that 089/Shocker Buruburu was a test run by the History Modifying Machine and that Shocker’s true plan is about to start as the horizon is being enveloped by a green aura.I absolutely loved this team-up I may not me as familiar with the current Super Sentai team, but to see Drive brought into conflict with them was brilliant. this is also a precursor to the Kamen Rider 3 movie, who has a small part throughout the film. hopefully we will see more Kamen Rider vs Super Sentais in the coming years.
