Description:In preparation for an impending, decisive battle, the strongest Demon King, Leonis, sealed himself away.
However, when he awakens 1000 years later, he finds himself reverted to the form of a 10-year old boy!
“Why!?”
“Why were you trapped inside of that? Don’t worry! I’ll protect you.”
Leonis is rescued by the beautiful girl Riselia, a student at Excalibur Academy, and is shocked to see how drastically the world has changed. The unknown enemy “Void”, the “Strategic City No. 07” and the weapon-shaped force, the “Demon Sword” are all new terms to him.
Despite being perplexed by these unfamiliar words, Leonis decides to enroll in Excalibur Academy. In a future world where magic has been lost, the curtain rises on a school sword-fantasy woven by the strongest Demon King and beautiful girls, involving both holy and demonic swords!
