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 19 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 one of the famous Kamen Riders, amongst other things. Now, Nick must use his newfound powers to fight enemies from 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. He’s just a passing through Kamen Rider, remember that!
