Alternate versions
Caster Lily

Caster (キャスター, Kyasutā?) is a Caster-class Servant able to be summoned by the Protagonist in the Grand Orders of Fate/Grand Order.



Caster's True Name is Medea Lily (メーデイア(リリィ), Mēdeia (Riry)?), the queen of Colchis, summoned as the younger aspect of Medea, from before she was called a "witch". Pure and innocent as a lovely girl, she has no vestiges of the "Witch of Colchis" or the "Witch of Betrayal" yet. Summoned as the Medea from before being cajoled by Jason, when she was being raised up like a princess while learning Magecraft from Hecate. A young girl with lovely bearing that anyone can love. If it wasn't for Jason, she would have lead a happy life.[1]


Medea Lily is summoned as her 14 year-old self.[1] Medea Lily's appearance differs significantly from her older self as her clothing possesses a lighter color scheme, with lavender purple being the predominant color of her robe compared to the dark violet in her older self's robe.

Another noticeable difference between the two is that Medea Lily is much more revealing in their choice of robe and lacks the cape Medea possess.


Medea Lily is pure and trusts people easily. Even towards the Master, she comes in contact with maximum affability. However, turning another way, this is nothing but something driven by the thoughts of "wanting to trust people". Be it the original Medea or Medea Lily, both are filled with distrust towards others.[1] Medea Lily is still completely infatuated with Jason, despite having memories of how events later play out.


Fate/Grand OrderEdit

Okeanos: The Four Sealed Seas of the EndEdit

Medea Lily appears with Jason, Hercules, and Hector on the Argo, searching for the Ark. Ultimately, she turns against Jason and through the use of a Grail, transformed him into one of Solomon's Demons via a blood ritual. They are both defeated by the Protagonist's party.

Salomon: The Grand Time Temple Edit

Medea Lily is one of the "Okeanos" Servants summoned to aid the Protagonist.


Just like her older self, Medea Lily primarily uses the Rain of Light spell as her main offensive spell via her High-Speed Divine Words skill. However, her Territory Creation and Item Construction skills are both inferior to those of her older self. She mostly cannot use offensive magecraft, but excels in healing-type magecraft. She also possesses two other Personal Skills, Poison Resistance and Romance of the Sea Foam.[1]

Her Noble Phantasm is Pain Breaker.
