Alter Ego (アルターエゴ, Arutā Ego?) is an Alter Ego-class Servant working as one of the three Alter Ego apostles of the Alien God in the Lostbelts of Fate/Grand Order: Cosmos in the Lostbelt. They are working in tangent with the seven Crypters attempting to supplant the Greater History of Man with the Lostbelts.[1][2] 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.[3] 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.


Koyanskaya Sniper


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.[3] 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.[3]
