The Demon Sword Master of Excalibur Academy
1000 years ago, Leonis Death Magnus, the King of the Undead, sealed himself in suspended animation with a plan to be reborn and re-marshal his demonic armies anew. Instead, he awakens to a world where magic has changed, a new race of monsters terrorizes the planet, and he’s now a 10-year-old boy. Fortunately, his beautiful “rescuers” think he’s a normal lad with amnesia and decide to send him to an elite magical school… which is the perfect place to give those plans for world conquest a serious rethink as he poses as THE DEMON SWORD MASTER OF EXCALIBUR ACADEMY!
