Belittled as useless since childhood, Leo leaves the mountains for the Royal Academy entrance exam—only to perform miracle after miracle. A wealthy bully targets him, but he endures quietly. When Dragon Isle unleashes its horde and the Blood Abyss Dragon breaks free, his masters reveal the truth: Leo is Odin's son. He awakens the Oblivion Stone, kills the dragon in one strike, and saves the world.
