Open Pokémon with Kamen Rider Style

After being killed by a dump truck, he followed through the big stream and came to a new world. When he saw that he was delivered by a lucky egg, he thought he was in the world of Pokémon. Later, I discovered that Dr. Oak was in this world and the buildings were the same as in the previous life. I thought I was in an urban Pokémon world. But can anyone explain to me what the hell the Kamen Rider in front of me is, holding a Pokédex driver and using a Poké Ball to transform into?
