A middle-aged man finally achieves his dream of becoming a freelancer. But on his way to a long-distance business trip, a freak accident in a highway tunnel changes everything.

He wakes up reincarnated into a strange, hybrid world—a fusion of Medieval Europe and Feudal Japan. He is now the eldest son and heir to a powerful Earldom with roots as a pirate clan. However, this new world is not a fairy tale; it is a cutthroat era of blood-soaked war and survival of the fittest.

Driven by two conflicting desires—to use his high status for carnal pleasures and the desperate need to survive—he begins to navigate the treacherous political waters. Little does he know, his struggle to balance his lust and his life will eventually reshape the entire world.

This is the chronicle of a man who, in the eyes of future generations, would be remembered as a legendary hero.
