Do-Hun, born into poverty with two Black-grade, unique evolving abilities - an Emotion Amplifier and a Chord to Power that converts feeling into raw strength - earns a fraught place at the prestigious Ludwigsburg Knight Academy to lift his family out of debt, only to be scorned, monitored, and pushed to the edge. Under the gruff tutelage of a disgraced knight and the cautious care of a young healer, he learns to fight and survive while four conflicting voices (Red, Blue, Green, Pink) begin to surface in moments of crisis, shaping his powers and decisions in unpredictable ways; the academy, predatory loan-sharks, and a shadowy syndicate called the Archivist all see him as either a threat or a commodity. Fragmented dreams and strange relics hint at a life he cannot remember, and every forced evolution raises the stakes - saving his loved ones one moment and drawing deadly attention the next. As Do-Hun trains, befriends rivals, and scrapes for control, the voices remain an unsolved mystery whose origin - and the cost of following them - will be revealed only after he has already been changed.

His power grows louder the more he listens—but the quietest voice might be the only one trying to save him.
