Synopsis
As the battle against the dark forces approaches its conclusion, only the Undead King Leonis Death Magnus remains among the Dark Lords. Realizing he requires greater strength to achieve victory, Leonis seals himself underground, intending to be reborn after a thousand years to rebuild his demonic armies. But the world has transformed drastically in his absence. The war that led to Leonis's retreat is forgotten, replaced by a new threat: monstrous beings called Voids. Magic has been supplanted by advanced technology, and those with special abilities, wielding weapons known as Holy Swords, are trained at Excalibur Academy to combat these Voids. Reborn as a ten-year-old human boy, Leonis encounters Riselia Ray Crystalia, a diligent girl who discovers the remnants of his resting place. Believing Leonis has lost his memory, Riselia decides to assist him and enrolls him at Excalibur Academy. Despite his ambitions to conquer the world, Leonis must first navigate a world entirely different from the one he once knew.
