The Demon Sword Master of Excalibur Academy

For a millennium, one of the most formidable demon lords in recorded history remained imprisoned within an ancient seal. When that binding finally shatters, Leonis expects to reclaim his terrifying dominion over the world. Instead, he opens his eyes to discover that his resurrection has come with an absurd catch: his overwhelming power is now housed within the body of a ten-year-old boy. Stripped of his imposing physical presence but retaining his vast magical knowledge, the reincarnated lord finds himself under the unexpected guardianship of the very girl who broke his seal. Bound to her care and forced to adapt to a drastically changed era, Leonis must conceal his true identity while navigating a reality far removed from his dark past. His new life leads him directly into the halls of Excalibur Academy, an institution where danger lurks behind every corner. Surrounded by unfamiliar threats and bound by the constraints of his youthful form, the legendary demon lord must rely on his cunning and hidden strength to survive the perils of his new academic environment.
