In the continent of Ovan where music flows, everything has a rhythm, and magic and melody are intertwined into an ever-changing wonderland. Lelan, who was born in the secretive Qin clan, is gifted and can hear the voices of all living things. However, due to a forbidden song, he lost control and was exiled to the edge of the music world. Legend has it that the Voice of Obsidian is awakening, trying to swallow up all the music in the world and turn magic into silence. In order to find the lost clan song and redeem the family's glory, Lelan embarked on a journey, partnering with a drummer who can control the wind and a spell caster who can turn words into sounds. They must navigate the rifts of music, dance with the musical beasts, and fight against the demonic tide of silence. Lelan's motivation is not only to return home, but also to explore the origin of music: Are notes a bondage or a freedom? The story takes the magnificent and bizarre world of music and monsters as the stage, plays a symphony of adventure and redemption, challenges the boundaries of language, sound and magic, and draws a magical journey of monsters where sound and destiny are intertwined.
