Become Agent Knight Z in the World of Magical Girls

[Magical Girl + Kamen Rider Zez + Multiple Heroines] Traveling to a world full of magical girls, both parents died at the beginning, leaving only a sister who is not related to him by blood. I originally expected that as a boy, I could transform into a magical girl. After all, the male protagonists in magical girl novels are like this. But, you tell me, I can't change at all? Are you kidding, that's not what the novel says! Am I not the hero in the novel? Fortunately, there is no perfect road. As long as I want to walk, the road is at my feet! Obtain the driver of Kamen Rider Zez and become invincible in the world! However, why is the body used to act as an agent actually a little lolita? Originally, I just wanted to live a double life as an ordinary person on the surface, but secretly an agent and a Kamen Rider. But, you magical girls are looking at me more and more wrong? Why, why even my sister looked at me strangely. Yeah, don't come over here!
