Mask: Negate the Shackles of Killing and Unlock the Lost Knight

In 2000, Grunge awakened, and humans used blood and bones to create Kamen Riders and establish the Knights Alliance. After twenty years of bloody fighting, the monsters were driven over the high wall, and the world finally took a breather. But this peace completely collapsed in 2020. In an underground stronghold in an abandoned building, a black-haired young man who had lost all his memory woke up, wearing strange armor and holding an orange short blade in his hand. He didn't know who he was or where he was. He only had an instinct carved into his bones - to kill. The ant soldier team fell into a pool of blood one after another, each strike was as accurate as if it had been rehearsed thousands of times. It wasn't until Inspector Chifeng intercepted him with the golden X armor, holding his sword against his throat, that he was forcibly stopped by his superiors at the last moment. "Take him back for questioning." But no one knows what is hidden in the body of this reaper codenamed Owl Shadow. When the top brass of the Knights Alliance opened the files that had been sealed for more than ten years, they discovered that the certification of this lost knight system only recognized one person who had died long ago. The war is still spreading, and the truth has just emerged. Wherever the Kamen Riders are, it's never peaceful. This novel and its characters are purely fictitious.
