[Original setting + pseudo-invincibility + no harem + grounded tone]
Zhou Xingyu unexpectedly wakes reborn in high school. Full of questions, he unlocks a System that has no presence whatsoever and becomes a so-called Demon King. Zhou Xingyu hates all the fighting and killing, and only wants to live an ordinary, peaceful life. He knows nothing about starting a business and can only work for someone else, but he's perfectly content with that.
Yet no one who gains the power of a Kamen Rider can escape their fate, not even him...
Zhou Xingyu watches as his childhood friend steps in front of him, blocking countless monsters to give him a chance to escape...
He watches his teacher face off against his friend, each trying to prove their ideals to the other...
He watches the world crumble under the conflict between Kamen Riders and monsters, and feels the world's malice toward him...
He sighs, expressionless, takes out the Decadriver, and says those words that feel both familiar and strange.
“I'm only fighting for my family...”
“I'm only fighting for the world...”
“I'm only fighting for peace...”
Looking at the new world he created, his childhood friend smiling, his teacher and friend reconciled, and the world at peace, he grins.
“Demon King? Not even a dog would take that job.”
