Alter Ego (アルターエゴ, Arutā Ego?) is an Alter Ego-class High-Servant appearing in the Lostbelts of Fate/Grand Order. She is later summoned by Ritsuka Fujimaru.



Alter Ego's True Name is Sitonai (シトナイ?), a Pseudo-Servant in the body of Illyasviel von Einzbern and a composite High-Servant.[1][2]

The Saint Graph's registered True Name is Sitonai. This is due to the fact that it seems like Sitonai is the one who manifests the strongest outside among the three Heroic Spirits (Divine Spirits) gathered inside the yorishiro.[1]

The person who became the container for these Divine Spirits is not a human Mage, but the latest and the final Homunculus created by the Einzberns. One possessing Command Seals that cover the entire length of her body, first-class precision in Magecraft and the best performance when it comes to being a Master. The ability to function as the Lesser Grail is also concealed in that body.[1]



The first component of the Alter Ego is Sitonai of Ainu mythology.[1]


The second component of the Alter Ego is Louhi (ロウヒ?) of Finnish mythology.[1]


The third component of the Alter Ego is Freyja (フレイヤ?) of Norse mythology.[1]



A girl who shows a pure smile. However, that smile hides a great cruelty----[1]

Personality-wise, she resembles that of the homunculus who became the base. The young Heroic Spirit Sitonai of the Ainu who displays the courage to fight unfitting of her age, the Goddess of Love Freya who shows sympathy to her opponents, and the witch Louhi who mercilessly slaughters her opponents... While it is possible to manifest any aspect of their personalities into the Alter Ego, for now it takes after the personality of “the girl who became the vessel”.[1]

Not good with cats.[1]
