The Multiverse, a term given to the group of parallel worlds, dimensions, realities, realms, or universes. And in one of these dimensions, known as Dimension-1218 (also known as the “Real World”), this “Multiverse Theory” has never been actually proven true. That is until an autistic 18 year old boy named Nick Brown, who just graduated from high school a year late due to the Covid-19 Pandemic, discovers a mysterious, yet familiar-looking, belt and a book containing bizarre cards, each depicting either one of the famous Kamen Riders, Super Sentai/Power Ranger, or a monster, amongst other things. Now, Nick must use his new found powers to fight enemies from the supernatural, the paranormal, the mythological, and other dimensions, while also traveling to these alternate worlds, as the new Defender of Worlds, and successor of the Destroyer of Worlds, and maybe also find a world where he’ll find a sense of belonging. And, what if Nick and his siblings, who also become Kamen Riders, become the new Power Riders (known in the Japanese original as; Kamen Sentai Goriders), a Super Sentai/Power Ranger-Kamen Rider hybrid team, with all of the powers and equipment of the two superhero legacies, and they also team up with individuals who died in their Dimensions of origins, but mysteriously been revived? He’s just a passing through Kamen Rider, remember that!
