The Utterly Evil Trickster Villain, Starting with a Golden Cavalry

My name is Huairen. As you can see, I’m a bad person. Now I’ve transmigrated into the world of Kamen Rider Drive and awakened a System called the Strongest Villain in All of Tokusatsu System. But to activate it, I have to save Banno. So I look at Banno’s belt, which is about to be given a loving father-son beating, and break into an evil smile.
