Arya, who possesses the bloodline of the Beast King, is reborn and returns to the pivotal moment of the Beast Selection Ceremony. Aware of the tragedy that befell her in her past life—where her sister Selena, also retaining memories of the past, used the same old tricks to snatch away Shadow, the Dragon Prince who was rightfully hers—Arya resolves to change her fate.
Lieyan, the young heir of the Phoenix clan, voluntarily pledges his loyalty to Arya, while Shadow secretly aids her from his position by Selena's side. Frustrated by her inability to win Shadow's heart, Selena colludes with the Demon race to gain power. Arya discovers the Seal of the Dragon Soul, breaks the seal binding Shadow, and dissolves the forced contract. During the Great Beast War, Arya joins forces with the two divine beasts to thwart the demons' plot and punish the malevolent Selena; she then ascends to the throne of the Beast King, abolishes the system of forced contracts, and grants all contracted beasts the right to choose their own masters.
