Human girl Lilith takes a job at Wildbeast Zoo to save her gravely ill sister. She soon discovers she has divine‑grade psychic purification power, able to calm raging beastmen. Wolf‑king Arthur, nine‑tailed fox Simon, and snake‑director Sarka approach her for her power but fall for her along the way. When her sister is abducted by beastmen, the three fight desperately to save her. After a life‑or‑death ordeal, Lilith awakens her full purification ability, defeats the enemy, and finally shares her home and love with the three beastmen who stood by her.
