Alter Ego (アルターエゴ, Arutā Ego?) is an Alter Ego-class Servant working alongside Beast VII in the Lostbelts of Fate/Grand Order: Cosmos in the Lostbelt. While working in the same capacity as the three apostles of the Alien God, she is an independent agent currently attempting to become one of the seven Beasts. She assumes the name TV (Tamamo Vitch) Koyanskaya (TV(タマモヴィッチ)・コヤンスカヤ, TV (Tamamo Vicchi) Koyansukaya?), acting as a human with the Russian "NFF Service". She is hired as Goldolf Musik's assistant before revealing her true motives.[1] She appears similar to the Assassin used to promote the Cosmos in the Lostbelt, but they are not yet confirmed to be the same person.



Alter Ego's True Name is Tamamo Vitch (タマモヴィッチ, Tamamo Vicchi?),[2] one of the members of the Tamamo Nine.


Alter Ego appears to be a voluptuous young woman with long pink hair and gold eyes. She wears a white suit jacket that is strategically a few sizes too small, a matching skirt that isn’t, and a pink scarf.[1] Koyanskaya wears two accessories that hint at her true identity as (a) Tamamo. Her glasses are identical to those worn by Assassin, and her earrings have the same geometric ‘fox-head’ shape as the symbol on Tamamo no Mae Lancer’s bikini. Also worth noting is that her gold eyes are the exact same color as Tamamo’s, though their hair colors differ slightly.

In the Chinese Lostbelt, Koyanskaya had her ears and tails out in the open and hair arranged in buns and wears a Chinese qipao with a frontal cutout in the same geometric fox-head shape as her earings (and Tamamo Lancer’s swimsuit) that shows off her lower chest, with a bell hanging from the center.


Alter Ego acts very professional at first and tries to act cute but is very sadistic and has no remorse when taking out lives of other Chaldea crews and is unwilling to let anyone go alive during the attack.[1]

As noted by Kotomine, she has a strong sense of self-preservation and will prioritize her survival above all else, like a rat fleeing a sinking ship. This is best shown during the Yuga lostbelt, where after having been beaten by Arjuna Alter's forces, Vitch shamelessly begged for aid from Chaldea to avoid being killed via a hastily written hitch-hiking sign.  She states her goal is to become a nine-tailed fox, one separate from the original Tamamo, and thus a new Beast of Calamity of her own design. 


Fate/Grand OrderEdit

Prior the events of the second prologue, she met Goldolf and convinced him to buy Chaldea and become the director. She assassinated every competitor in the way so he could have the sole monopoly over the observatory.[3]


Alter Ego was seen walking alongside Father Kotomine.

Second PrologueEdit

Koyanskaya confronts Ritsuka Fujimaru after their interrogation, but is interrupted when Fou attacks her. She responds in kind, kicking and grinding him under her heel, and implies that she knows both of his true nature and that his powers and sapience are significantly reduced. Keeping him in place, she coerces Ritsuka into a small interrogation of her own in exchange for freeing Fou.[1]

Anastasia: The Permafrost EmpireEdit

Götterdämmerung: The Eternal Ice-Flame CenturyEdit

S I N: The Land of Unified KnowledgeEdit

Vitch appears in the Chinese Lostbelt with her ears and tails out in the open. The king of the third lostbelt reveals her identity as Daji (妲己), the favorite concubine of the ancient king of China, Zhou of Shang, who was also portrayed to be an evil fox in Fenshen Yanyi.

Yuga Kshetra: The Black Final GodEdit


As an apostle of the Alien God, she has the ability to move between the Lostbelts.[4] Two of her Skills are Presence Concealment and Independent Manifestation.[2]



Alter Ego temporarily manifests as a Beast, but she has yet to fully reach that status. Called Treasured Beast (愛玩の獣?), she possesses the Skill Nega-Weapon.
