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?
