The Strongest Mage

5000 Years Ago in the Golden Age of Magic, There was a demon who was the strongest mage at that point in time

Many mages came to challenge or kill him.......They all failed

Until the demon got bored and after he sealed himself away to wait for someone to give him a challenge

Years later after the Demon lord was killed by Himmel's Party. A child was being chased by wolves stumbled upon the demon and accidently unsealed him

Now unsealed this demon now took this girl under his wing hoping he can train her to become stong

What was this demon's name you ask

His name was Schnitzel The Strongest Mage and The True King of Demons
