Caster of Okeanos (オケアノスのキャスター, Okeanosu no Kyasutā?) is a Caster-class Servant able to be summoned by Ritsuka Fujimaru in the Grand Orders of Fate/Grand Order.



Caster's True Name is Circe (キルケー, Kirukē?). She is the daughter of the sun god, Helios, and is also the aunt of Medea. She appears in the epic poem of Homer - the "Odysseia". A famous witch from the mythology of Aeaea Island. A demigod that presides over the moon and love, related to the genealogy of the goddess Hecate. A rikejo that has the mixing of a magic drug that brings about various effects and mutations as her forte.[1]

Although she would show a warm welcome to the human men that visited her island with by entertaining them with a feast, she turned them into lions, wolves and pigs upon growing bored on them. Her older brother is Aeetes (the King of Colchis・father of Medea). Her younger sister is Pasiphae (wife of Minos, King of Crete・mother of Asterios).[1]

When the Sea God Glaucus sought a love advice from her, she grew jealous after being rejected by Glaucus once they had an illicit affair and ended up turning his beloved maiden Scylla into a monster. Said Scylla would later devour six of Odysseus’ subordinates. The hero Odysseus stopped by Aeaea Island on his way back to his homeland and was offered a poisoned wheat porridge by Circe, but she took a liking of him in the end as a result of breaking her magic with the divine protection of Hermes. When Odysseus departed, she gave him useful advice for avoiding hardships in his travel.[1]


Circe is a young woman with long pink hair, blue-green eyes and fair skin. Notably, her ears are pointed, giving her an elf-life appearance. She wears a golden tiara, a light tunic with a short skirt, and gladiator sandals.

The reason why, after a certain point of time, she drastically cut her beautiful hair short - which even Homer praised - was due having experienced a severe unrequited love that completely overwhelmed her.[1]


The witch of temptation and depravity, famous in mythology. An eternal maiden, with a tendency to fall in love and become deeply jealous. Innocent and pampered, her wiles in caring for another truly has the taste of a forbidden nectar. However, one must be careful about how to refer to her. That is, if you still want to remain a human...[1]

Circe dislikes cats, due to her belief that cats take advantage of others with their adorable appearance, along with how cats were involved with something in regards to Medea. She has also shown a dislike for being called "short".

Circe likes to boastfully call herself the Queen of Witches that only worships one diety, Hecate the goddess of witchcraft and necromancy.
