Luna, Poseidon's illegitimate daughter, born power-sealed, raised mortal. Barred by gods from the Olympian Divine Academy, she lands in the Eros Divine Beast Sanctuary. She unknowingly soothes three rampaging beasts, binding Celus the black dragon, Griffin, and Charles the hellhound to her. Bullied and ostracized, she awakens her beast-taming gift, wins a love rivalry, and becomes Sovereign of All Beasts.
