Caster of Okeanos (オケアノスのキャスター, Okeanosu no Kyasutā?) is a Caster-class Servant 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 the aunt of Medea through her brother King Aeëtes of Colchis and the aunt of Asterios through her sister Pasiphaë. 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" or anything that makes her feel older than she wants to feel, such as being referred to as an "aunt" by Asterios.

Circe likes to boastfully call herself the Queen of Witches that only worships one deity, Hecate the goddess of witchcraft and necromancy. According to Medea, Robin Hood seems to fit Circe's taste in men. She also showed attraction, as well as hostility, towards Odysseus and his schemes. In Circe's White Day event, she confronts and gets over this.


Fate/Grand OrderEdit

Salem: The Taboo Epiphany GardenEdit

Other Appearances Edit

Circe appears in Fate/Requiem as a commentator for the Holy Grail War Tournament.


She wields a staff of hecate similar to Medea, with noticables differences like its colors and head. The head in particular possesses five downward rays within the moon cut-out and feather like projections along the outer edge which lenghtens into a massive blade at the peak of Circe's power.

Circe had a forte for herbalism and potioneering, which allowed her to create a variety of drugs, even those that can affect servants, such as the potion that allowed Mata Hari to survive her hanging by placing her in short-term suspensed animation. 

With her command over divine words, Circe can instantly actualize great magecraft like surge of lightnings from the tip of her staff, call forth twisters, and her variation of the Machia Hecatia Graea: Rain of Light spell which she fires as laser cannon. But her favorite spells are those that deal in polymorphing her victims into helpless animals, such as pigs. 

Circe seems to possess some control over Scylla, the nymph she cursed and transformed into a sea monster. With a wave, Circe can call forth a grail-like object that floods the ground with a dark mud-like substances that acts as a portal. Scylla's dog-headed tentacles then rises from the inky depth to tear apart Circe's enemies on her command. 

Befitting her name as the "Falcon Witch", Circe has acquired a mystic code in the shape of falcon wings. While they are noted to be fake and more akin to an accessory one would wear, Circe has grafted them to her magic circuits, causing them to glow in a similar pattern to that of Medea's cape. Despite their artifical nature, the wings are fully functional, allowing Circe to easily take flight and even fire off the feather as projectiles. 

Her Skills are Item Construction (A Rank), Territory Creation (B Rank), High-Speed Divine Words (B Rank), Poisoned Meal (A Rank) and Advice for Sailing (A Rank).

Her Noble Phantasm is Metabo Piglets, a reality marble of summoning. It calls forth the forbidden feasts she often held for wayward and unwitting sailors back on her island of Aeaea. Anyone who gets drawn in by temptation and consumes the poisoned feast will be turned into pigs for Circe's amusement.
