Plot
Hamel travels north toward the demon-continent, wielding a magical violin said to compel evildoers to repent and take their own lives. In reality, he is a deceitful, greedy coward who extorts those he supposedly saves. After liberating the village of Staccato from demons, he demands an orphan girl, Flute, as payment, forcibly taking her with him. Accompanied by his talking crow, Oboe, they begin their treacherous journey, marked by Hamel's constant scheming and mockery.
Their path soon crosses with Raiel, the noble Hero of Love and Hamel's childhood friend, who wields a massive golden piano capable of summoning spirits and bending wills. Their reunion erupts into a violent but inconclusive clash. Later, they encounter Trombone, the young prince of Dal Segno, a warrior kingdom annihilated by demonic forces. Witnessing his parents' murder, Trombone swears vengeance and joins the group.
As they press onward, their struggles escalate into battles against formidable foes, culminating in a confrontation with Sizer, the Hell Hawk King and one of the demonic Lords of Hell. Hamel's violin is shattered in the fight, revealing his true lineage—he is the son of the Demon King Chestra, and his quest is not for glory but to confront his father and rescue his mother, Pandora.
Their journey leads them to Sforzando, a powerful kingdom renowned for its magical knights and healing arts, ruled by Queen Horn, the world's strongest woman. There, Flute discovers she is the lost princess of Sforzando, abandoned as an infant to protect her during wartime. Though briefly reunited with her mother, Flute struggles with resentment and confusion. Meanwhile, Hamel departs to repair his violin, only for Sforzando to come under siege by the demonic forces of Drum, the Dragon King, and Guitar, the King of Beasts—both Lords of Hell. A brutal battle ensues, ending in Drum's defeat after transforming into a monstrous hydra.
With Sforzando saved, the group prepares to resume their journey. Queen Horn reveals her life is dwindling due to the toll of her barrier magic. Flute, torn between staying with her mother or following Hamel, ultimately chooses the latter, her feelings for him growing despite his cruelty. The party then scatters—Raiel returns to Staccato, Trombone visits his fallen kingdom, and Hamel, Flute, and Oboe continue northward, joined by Cornet, the younger sister of Clarinet.
In later events, a new tale follows a boy named Schel, an aspiring wizard who crosses paths with Great, Hamel's son, though their story unfolds separately.
