Casey Stone and Melly Stone, daughters of the Stone family—the strongest beast tamers in the beast world—awaken their beast-taming arts on their coming-of-age day. They must choose powerful beast-men for dual cultivation to enhance their spiritual power and summon mighty spirit beasts, becoming the Sovereign of All Spirits to consolidate beast tamers' rule over beast-men. In her previous life, Casey awakens the Beast Horde Summoning ability while Melly awakens Ferocious Beast Transfer, which she uses to frame Casey for all the savage beasts she summons. Casey is branded a disaster and dies miserably. But Casey returns to the past, and this time she awakens Beast Bloodline Evolution, the ability to upgrade any ferocious beast into an ancient divine beast. She's fully prepared to ruthlessly expose those who cause her death.
