The strongest Demon Lord Leonis sealed himself to prepare for an inevitable final battle. But when he awakens after a thousand years, he has reverted to the body of a 10-year-old boy. Rescued by the beautiful Liselia of the Holy Sword Academy, Leonis is stunned by the changed world: mysterious enemies called the Void, the Seventh Tactical City, and supernatural powers manifesting as weapons-the Holy Swords. Though bewildered by these unfamiliar terms, he enrolls in the academy. In this future world where magic has vanished, the stage is set for a sword fantasy of Holy and Demon swords woven by the strongest Demon Lord and beautiful heroines.
