    Short summary describing this character.

    No recent wiki edits to this page.

    Caster served as Souichirou Kuzuki's Servant during the fifth Holy Grail War. She was initially summoned by a man who refused to take an active role in the Holy Grail War. Caster tricked him into using up his Command Spells before she found Kuzuki. Caster is a manipulative schemer who excels at magic and is skilled at reading the momentum of the war.

    As a Caster class, Medea is exceptionally powerful at spell-casting. She is also adept at creating a territory where she turned the grounds of Ryudou Temple into a place that further empowers her spell-casting. Because of her vulnerability in direct combat, she resorts to any possible means to win the war, including summoning a Servant, Assassin. Caster's greatest weakness is Berserker, and her strategy to win the war revolved around defeating him.


    Medea is the princess of Colchis who owned the Golden Fleece that Jason of the Argo Expedition wanted. The King of Colchis refused to give Jason the Golden Fleece, thus Aphrodite made Medea fall blindly in love with Jason. Medea helped Jason obtain the Golden Fleece while under Aphrodite's control.

    The King of Colchis then led his army to capture Jason, but Aphrodite made Medea board Argo and cut her brother Apsyrtus to pieces right before her father's eyes. Upon returning to Iolcus, King Pelias refused to return the country to Jason and plotted to assassinate him. Jason relied on Medea's magic 3 times to escape the assassination attempts.

    Medea then tricked King Pelias into getting killed and Jason reclaimed the throne. The Argonauts disapproved of Jason's methods and Medea's actions. She was denounced as a witch and was cast out of the country with Jason. They ran to Corinth and were welcomed by the king.

    The King of Corinth took a liking to Jason and offered him his daughter's hand in marriage and Medea was exiled. Medea later attended Jason's wedding and burned everything and everyone there except Jason. After that, the common folk treated her as a witch and blamed her for all the misfortunes that they experience. Medea was powerless to change their views and instead took to hating everyone.

    Fate/Stay Night

    Caster was initially summoned by a passive man who wished to wait the war out. Tired of waiting, she tricked him into wasting his Command Spells and killed him. Caster then wandered around Fuyuki City cursing her fate when she found Souichirou Kuzuki. He helped her without question and took Caster as her Servant. She fell in love with him because he was the first sincere man to help her.

    Since then, Caster used Ryudou Temple as her base of operations. She casted a spell on the city to siphon life energy from the local populace to fuel her magic. She also conjured a large barrier which surrounded the temple grounds. Any enemy Servant who attempt to force through will have their power drained. The only spot that is open is the front gate which is guarded by Assassin.

    At the temple, Caster presented herself as Kuzuki's bride-to-be and she was allowed to stay at the temple in the guise of planning for their marriage.


    Ryudou Temple was assaulted by Saber but she was denied entry by Assassin. Later, Caster attacked Shirou's home but she was killed by Gilgamesh.
