Rayleigh was a champion, a top duelist in the World Championship. He won seven consecutive WCS titles. Unfortunately, his favorite card game went bankrupt. It was deemed worthless and unprofitable.

Devastated by the sudden loss of his passion, he fell into despair and became reckless, eventually taking his own life. His regret was ingrained in his bones and soul. Yet, in the depths of his sorrow, his dried tears managed to conjure up a miracle.

Falling from the sky, he found himself naked, sitting on top of a fat king who looked like a pig and surrounded by people with spears and arrows.

He realizes that this is a completely different world. With his years of formidable dueling experience, in a world ruled by Card Game, he will become the King of the Federal Monarchy by defeating rotten democracy and bastard capitalism!
