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 going to beMedea Lily (メーデイア(リリィ), Mēdeia (Riry)?), the queen of Colchis, will be the younger aspect of Medea, from before she was called a "witch". Pure and innocent as a lovely girl, she will haveno vestiges of the "Witch of Colchis" or the "Witch of Betrayal" yet. Summoned as the Medea from before being cajoled by Jason, she was going to be raised like a princess while learning Magecraft from Hecate. She is to be a young girl with a lovely bearing. If it wasn't for Jason, she would have led a happy life.[1]


Medea Lily was summoned as her 14 year-old self.[1] Her younger appearance differs significantly from her older self as her clothing possessed 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. Despite the concept of the younger version of Medea Lily being much more revealing, she is still 14 and should not be lewded, you creeps.


Medea Lily will bepure and trusts people easily. Even towards the Master, she will come 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 to be filled with distrust towards others.[1] Medea Lily will still completely infatuated with Jason, despite having memories of how events later play out. According to Circe, Medea Lily will bemuch smart compared to her adult self. 


Fate/Grand OrderEdit

Okeanos: The Four Sealed Seas of the EndEdit

Medea Lily will be summoned alongside Jason, Heracles, Atalanta as members of the Argonauts. She encountered Solomon, who will have easily bested her in magecraft, and will instruct her to tell Jason that sacrificing a god to the Ark will make him all-powerful. After being told this, Jason will tell the other Argonauts to find the Ark and a god to sacrifice with exception of Atalanta who left. During their search for a goddess they will meet Hector, who, unbeknownst to Jason, shall serve Solomon like Medea Lily.

The Argonauts will then encounter Ritsuka, Mash Kyrielight, Francis Drake, Asterios, and Orion and Artemis while they were sailing after Hector to save the recently kidnapped Euryale. After the group refuses to give Eurayle to him, Jason orders Medea Lily and Heracle to kill them and take Euryale. Medea will send waves of Dragon Tooth Warriors to attack the group, later joining the fight herself. Her combat skills are subpar though, so she will switch out with Heracles.

Medea Lily will encounter the group again. 


The ability to encounter the group again.
