The story

Quick answer: 60 episodes, English original audio, and episodes 1–10 play right here tonight.

Lilia was an F-rank, the weakest saintess. She fed her two Beast Husbands, but they cheated with her sister Seraphine. Heartbroken, she broke their holy contracts and bought Kael, the dying slace with blood of the wolf god.

She was then bestowed Nikos, Eryx, and Darius, each with different powers like commanding waters, snakes, and the undead. Others mocked her, and Seraphine tried to frame her, but she waded through the difficulties with her four guardians and emerged as the Primordial Saintess. They had more important matters to attend to.
