Shadow Monarch in a normal modern world not until...

Synopsis: Reborn into a peaceful modern world devoid of monsters, dungeons, and magic, Drix finds himself in the body of a newborn, carrying the immense power of the Shadow Monarch. With no threats to face and no enemies to fight, Drix embraces his new life, honing his abilities in secret while enjoying the tranquility of a normal existence. Over the years, he grows to accept this world as his sanctuary—a place where he alone wields power in a calm and ordinary society. But just as he begins to fully settle into this quiet life, an unsettling, familiar sensation pierces the calm. Mana—an energy he thought impossible in this world—begins to emerge, spreading slowly but surely. As the once-ordinary world starts to shift, Drix must prepare for whatever lies ahead.
