Am I a Kamen Rider or the real young master who was switched at birth?

[Kamen Rider + True Young Master and Stuttering Fake Heiress + With Knight Spirit] (There's a minor villain from another world at the beginning, but he doesn't play much of the story, so please don't enter if you don't like that.)
Others transmigrate with a cheat system from the start. Ye Yang transmigrates with a magenta camera from the start. In his previous life, Ye Yang's world was invaded by monsters, and he was on the verge of death when Kamen Rider Decade and Kamen Rider Sora descended from the sky and saved him. Afterwards, everyone said he was obsessed with tokusatsu (special effects) and almost sent him to a mental hospital. Only Ye Yang knew that as the only person in the world who remembered the truth, he was definitely in big trouble. Sure enough, he was suddenly launched into flight by a Kamen Rider. The instant he was launched, he arrived in a white, misty space, and standing in front of him was the Kamen Rider who had passed by. Kamen Rider Decade handed him the same magenta camera and said: Young man, your journey begins.
Ye Yang only had time to shout, "Please don't be stupid enough to film any Zi-O spin-offs! You'll become a Pond Guardian!!" before he was transported to another world. A new life, still switched at birth, still an orphanage, still a disastrous start. Ye Yang just wanted to ask Kamen Rider Decade: If you're going to transport me, at least let me be transported to a better family!
Things got increasingly outrageous—
What? I'm the only son of the Lin family patriarch?
What? I have three older sisters?
What?! The fake heiress I was switched at birth is actually my online friend of several years?!
Ye Yang raised his camera and took a picture of his stunned face.
The magenta camera records the world, and he is responsible for finding all the moments worth pressing the shutter in this messed-up and absurd life.
