Olga Marie Animusphere

Olga Marie Asmleit Animusphere, also known as Olgamally Animusphere, is the daughter of Marisbury Animusphere and heir to the Animusphere family of magi, one of the top 10 families in the Clock Tower.

She joined Chaldea initially as a Master candidate though she had to step up and assume the control of the Grand Order operation after her father's death. Though severe, arrogant and uptight she still shows compassion and cares for her subordinates within the organization. She trusts and relies on Lev Lainur as a fellow researcher and for support in her duties.

In Fate/Grand Order - First Order ~! She is apparently Rayshifted to Singularity F together with Fujimaru and Mash but in reality, only her consciousness was shifted while her body died in the explosion that engulfed the laboratory. Returning back to the current era would mean her mind would die.

This truth is revealed to her by Lev himself, who comes out as the traitor who set the explosives in an attempt at killing all the Chaldean Masters and personnel. To smack her even more, Lainur uses the power of the Holy Grail to cast Olga within CHALDEAS. Since the machine is a miniature reproduction of the Planet comprised of potentially infinite data, being cast within is akin to being sucked into a black hole.!~
