I was once known as the "Phantom Demon," a ruthless, legendary powerhouse who lived a life soaked in blood, constant warfare, and exhausting martial conflict. After a chaotic demise, I unexpectedly woke up in a completely new body in a peaceful fantasy realm. Having experienced the utter exhaustion of the absolute peak of power, I have only one goal for this second chance: to live a perfectly lazy, quiet, and leisurely life.

The problem? Even though I want nothing more than to take afternoon naps, eat delicious food, and do absolutely nothing, the world won't leave me alone. Troubles, arrogant nobles, and dangerous threats keep knocking on my door. They think I'm a helpless target, completely unaware that behind my lazy smile lies the terrifying, world-shattering reflexes and combat experience of the Phantom Demon. While trying to keep my true identity a secret to protect my peaceful routine, I find myself casually crushing overambitious villains just so I can get back to my afternoon rest.
