The plot for the manga revolves around the hero Hamel who travels northbound towards the continent of demons in order to avert a great disaster. Using his magical oversized violin, he plays music that would force his enemies to repent for their sins and kill themselves – or so that was how the story should have been. The so-called Hamel is instead a selfish, cowardly, heartless, and immoral fiend that seeks to take advantage of those around him, and extort from those he saves. After saving the remote village of Staccato from nearby demons, he decides to abduct an orphaned girl named Flute as payment for his services. Hamel, Flute, and Oboe, Hamel's advisor who is a talking crow, head north on their long, arduous and ridicule filled journey. Along the way, they meet Raiel, the hero of Love who plays beautiful and powerful tunes that can summon spirits and manipulate people with his 500 kg solid gold piano; he is actually Hamel's childhood friend. Their first encounter results in a not so deadly battle for revenge. Next they encounter Trombone, the young prince of Dal Segno, the warrior nation renowned for their knights and their swordsmanship. Having his country burned to the ground and his parents murdered in front of his eyes, the young prince swears revenge and joins are party northwards in their quest. Adventure, hilarity, and humiliation ensues as Hamel leads the ragtag band north while performing street performances bicker with each other. Along the way, they fight dreadful enemies and eventually meet Hell Hawk King Sizer, one of the Lords of hell, the guardians of the Demons Legions. In a mostly one sided battle, Hamel's Violin is broken. It is also revealed that Hamel is actually the son of the Demon King Chestra, and that he heads north in order to defeat his father and save his mother Pandora.
