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 Mephistopheles (メフィストフェレス, Mefisutoferesu?), the demon of temptation that appears in Goethe's masterpiece, "Faust". Waging a bet with God on whether Dr. Faust would fall into depravity or not, Mephisto attempts to pull him into the path of evil. Mephistopheles exhausts all arts of coaxing and succeeds into enticing Faust into the path of evil. However, just before his soul was cast to hell, Faust had his soul saved by a loved one.[1]

In reality, the superior magus Faust coined a single Homunculus, named him Mephistopheles and was greatly affectionate to it, but was betrayed as matter of course and died.[1]

FGO Caster scene



“Ah, the fiend! The fiend! The fiend has come! It's Mephistopheles! The foulest fiend in all the world!”

Caster introduces himself as "the man who was born to be a Servant." Although he may seem loyal at first glance, he has an extremely cruel personality. He thinks of the Master as nothing but "a toy to entertain himself" and will try drive the Master into despair if given the chance. In other words, one just have to take the proper attitude as magus and do not trust him.[1] He mockingly states that he is a pacifist and that there is no one greater when it comes to serving with loyalty.


Fate/Grand OrderEdit

In his interlude, he confronts Faust.


Mephistopheles is neither a Human or Demon.[1] He wields a pair of scissors. His Noble Phantasm is Ticking Bomb.


Koyasu-ko (コャスコ, ?) is his nickname in Fate/GUDAGUDA Order because he is voiced by Takehito Koyasu, who also voiced Caster.
