Kamen Rider: Both the Red Emperor and a Monster

A man named Gu Yanwu accidentally arrived in the world of Kamen Rider Ryuki and obtained a System of his own. His very first beginner's reward was something like the nonexistent red Decade Driver. He could even transform into a monster modeled after a Chinese dragon. He could travel freely between different worlds, fight monsters to level up, and exchange points for cards, other items, resources, and more. Let's see what kinds of people the protagonist encounters and what stories unfold in all those different worlds!
