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]

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]

In battle, Sitonai wields a sword and a bow. She also fights using her fists and her familiar.[2] Her Noble Phantasms are Optateshke Okimunpe[1] and Pohjola Fimbul.


Her Class Skills are Territory Creation (A), Item Creation (B), Goddess's Divine Core (B), and Magic Resistance (C).

Snow Fairy (スノーフェアリー, Sunōfearī?) is an evolved version of the skill Child of Nature. It is the ability to spontaneously freeze any surrounding target. Once designated as an attack target, even loved ones can be frozen.[1]

Emotional Freezing (感情凍結, Kanjō Tōketsu?) is a skill which involves freezing one's emotions. While she is a girl who smiles innocently, her thoughts can sometimes become like that of a cold-hearted demon, and her mental state can be wielded as a weapon. The heart of ice may sometimes become a sword, or it may sometimes become an armor.[1]

Kamuy Yukar (カムイユカラ, Kamuiyukara?) is the divine hymn of he who claimed himself a Kamuy. As an Alter Ego, uttering the Kamuy Yukar allows Sitonai to borrow the power of various Kamuys in Ainu lore. It is possible for her to even use the power of the Pase Kamuys (the superior Kamuys) related to mountains, villages, and the sea.[1]

Crimson Gold (赤き黄金, Akaki Kogane?) is a skill of the Norse Goddess Freyja. She, who attracted not only gods but also giants, loved only one person and it was said that tears of crimson gold flowed out as Freyja wept thinking about him, who lived only to travel. This skill is not used in Fate/Grand Order.[1]
