Can a monster also become a Kamen Rider?

Justice? Evil? What is the exact dividing line between the two?
The world is not black and white, it’s just that more people want to see it in black and white.
Those who protect what they want to protect, carry out their beliefs to the end, and fight to the end regardless of life and death are called Kamen Rider.
Some knights fight to protect humanity, some fight to survive, and some fight to protect the dreams of others.
The green Desire Monster stared at the core coin in his hand and said, "I will fight for the justice in my heart."
"Please look carefully, this is mine, transform!"
ps: This is a novel that includes special effects and games. For the sake of atmosphere, the first two chapters use the first-person perspective, and it will return to normal from the third chapter~ (The author likes to write hentai~)
