Synopsis：In the beast world, the Stone family reigns as the strongest beast tamers. On their coming-of-age day, twin sisters Casey and Melly awaken their beast-taming powers and must choose powerful beast-men for dual cultivation to boost their spiritual strength, summon mighty spirit beasts, and compete for the title of Sovereign of All Spirits to secure tamers’ rule over beast-men. In her past life, Casey awakened “Beast Horde Descent,” while Melly awakened “Ferocious Beast Transfer” and used it to dump every savage beast attack onto Casey, branding her the “Calamity Girl” and leading to her tragic death. Reborn to that fateful day, Casey now awakens “Beast Bloodline Evolution,” an ability that can elevate any ferocious beast into an ancient divine beast. This time, she will overturn her fate, tear off every hypocritical mask, and ruthlessly drag all who ruined her into the abyss.
