The Priestess of the Alien God (異星の神の巫女, Isei no Kami no Miko?, lit. "Priestess of the God of Another Planet") is an unnamed woman who appears during the Cosmos in the Lostbelt scenario of Fate/Grand Order.



The identity of the woman is unknown. Before Chaldea is attacked, she is shown to be present in the Lost Room.[1]


This mysterious entity has a female humanoid figure and she has astral patterns covering parts of her body.


The woman remains silent and mostly emotionless. She is shown to react to seeing Ritsuka Fujimaru's destroyed room by gazing sadly at it,[2] and she reaches her hand out to Mash Kyrielight in the opening.


Fate/Grand OrderEdit


She was silently watching Ritsuka Fujimaru in the Lost Room.[1]

Second PrologueEdit

When Anastasia and the army of Oprichnik attacks Chaldea's headquarters, the strange woman walks through Chaldea's ruins, lingering in Ritsuka Fujimaru's room.[2]

The strange woman was at the hangar to see Ritsuka, Mash and Da Vinci and still unnoticed by anyone. She was present when the group went to save Goldolf Musik.[3]

Anastasia: The Permafrost EmpireEdit

She is present during the Crypters' meeting, silently observing them and only making a physical appearance when the meeting was over before disappearing from the place.[4]

The Priest can see the unnamed woman and calls her the Shrine Maiden of Another Planet (異星の巫女, Isei no miko?).[5]

She later appears at the end of the Lostbelt, destroying the Fantasy Tree "Orochi", in front of Chaldea, disappearing directly afterward.[6]

Götterdämmerung: The Eternal Ice-Flame CenturyEdit

She plays a minor role in the Norse Lostbelt, only making herself visible to Ophelia in her room and somehow pushing her into revealing why she couldn't finish Brynhildr when she had the choice before disappearing.[7] She later appears atop of Surtr's shoulders, surprising Ophelia. She seems trying to say something, but Ophelia is unable to read her lips, making her questioning if the Priestess is truly a being from another star.[8]

SIN: Land of Unified KnowledgeEdit

She unexpectedly appears in front of a restrained Koyanskaya. She seems to try to say something to the Alter Ego, but the latter is unable to understand her, due to the Priestess being unable to remember the human language, which makes Koyanskaya wonders if at least Kirschtaria can understand what she says. But even after her pleas of helping her escape, the Priestess looks unwilling to do it, dissapearing from the place as soon the voice of the Lostbelt King talking to the fox could be heared in the prison.[9]

Yuga Kshetra: The Black Final GodEdit

Peperoncino refers to her as "U-chan".[10]


The woman is shown to be present throughout Chaldea without anyone noticing her. She also completely froze and then shattered the Anastasia Lostbelt's Fantasy Tree with but a single touch.[6]

The instruments of the Shadow Border are unable to detect her presence, instead detecting simply [nothingness] where she stands. Holmes describes her as a void-like emptiness seeping out into the space around it.[6] She can somehow making her existence perceivable only for certain people, proven when, even in the same room, Sigurd in his spiritual form was unable to sense her presence nor see her, falsely believing his master was talking alone.[7]
