In the household of Helios, the god of the sun and the mightiest among the Titans, a daughter is born. However, Circe, the newborn, proves to be an unusual child—neither possessing the immense power of her father nor the dangerously seductive charm of her mother. Seeking companionship beyond her divine kin, she discovers an inherent gift: the ability to wield witchcraft, which empowers her to transform her adversaries into monsters and even threaten the gods themselves.
Feeling threatened by her newfound powers, Zeus decides to banish her to a secluded island. Here, she refines her occult skills, befriends and tames wild beasts, and crosses paths with numerous renowned figures from mythology, including the Minotaur, Daedalus, and his ill-fated son Icarus, the treacherous Medea, and the cunning Odysseus.
However, dwelling alone on the island poses its own dangers, and Circe unknowingly incurs the wrath of both men and gods. Eventually, she finds herself entangled in a fierce conflict with one of the most terrifying and vengeful beings among the Olympians. To safeguard what she cherishes most, Circe must muster all her strength and make a definitive choice—whether to align herself with the divine heritage she was born into or with the mortal world she has come to know and understand.
