In a world basking in the afterglow of a hard-won peace, the shadow of heroism looms large, threatening to eclipse the next generation. Ten years have passed since humanity triumphed over the demons, and expectations weigh heavily on the children of those celebrated saviors. Among them is Earth, son of the Hero, a young man burdened by his father's legacy and quietly resentful of the pedestal upon which he's been placed. Earth's life takes an unexpected turn when he discovers a sealed sword within his family's mansion – a relic that once vanquished the Demon King. Trapped within is the restless spirit of the defeated monarch, unable to move on and, inexplicably, visible only to Earth. Bound together by fate, they forge an unlikely and uneasy alliance. The Demon King, sensing Earth's simmering resentment towards his father and the world that idolizes him, offers a tantalizing proposition: unparalleled training, a path to power fueled by vengeance. Earth, yearning to break free from the gilded cage of his father's shadow, accepts. As Earth delves into forbidden knowledge and hones his skills under the Demon King's tutelage, the world around him begins to shift. Past heroes resurface, childhood friends reveal hidden depths, and the very foundations of their peaceful society begin to tremble. Will Earth succumb to the darkness within, or can he forge his own destiny in a world desperate to define him by his lineage? Dive into Anikki Burazza's *Breakthrough with the Forbidden Master* and discover a world where resentment can birth power, and even demons can offer a path to self-discovery.
