The Demon Sword Master of Excalibur Academy

With the war against evil all but decided, Leonis Death Magnus—the Undead King and last surviving Dark Lord—finds himself unable to win alone. He entombs himself far beneath the earth, planning to awaken a thousand years later through reincarnation and restore his demonic forces.

A millennium on, the world he returns to barely resembles the one he left behind. The old conflict has faded into legend, sorcery has given way to magical devices, and humanity now battles terrifying creatures known as Voids. At Excalibur Academy, gifted students train to face them, wielding powers that take shape as Holy Swords.

Reborn as a ten-year-old human, Leonis is discovered by the earnest Riselia Ray Crystalia in the ruins of his sealed chamber. Mistaking his situation for amnesia, she takes him in and helps get him enrolled at Excalibur Academy—leaving Leonis to navigate an unfamiliar age while quietly holding onto his ambition to conquer the world.
