(Scale, as in the musical term) Because of the general of the MagiCorps saved Schel from a Mozoku (Monsters of this world) he has a dream to become the greatest magician ever. So he travels to the capital Sforzando the magic city and enters the MagiCorps School of Magic. There he meets Great, a violin magical music user, who is also the son of the great hero Hamel, who defeated the Demon King Chestra. As Schel tries to become the greatest magician, he also holds some secrets of his own. But how will Schel survive magic school with so many rivals to compete against?

Pandora's Box led a cursed existence. Through the curiosity of a woman, evil was unleashed and very nearly covered the world in darkness. Miraculously, humanity managed to seal Maou Kestra back into the box, but only with immense sacrifices. Even without their lord, the demons are still a formidable force that has only grown stronger with time, locked in the abandoned capital of the North, Hameln. Fifteen years have passed since that fateful battle...

Enter Hamel, a travelling minstrel who is so self-centered that he'd sooner cook his guardian crow (and family friend), Oboe, than go hungry for even a minute. Welcome to the world of music and hilarious insanity that is the Violinist of Hameln. Watch as Hamel takes cheap shots at his opponents and bashes pigeons with his giant violin and turns them into dinner.

How WILL the world be saved from Maou Kestra (it's a pun for orchestra, if you haven't noticed) with a hero such as this?
