Vasilisa

Vasilisa (ワシリーサ) is Sasha's superior, and the head of Annihilatus.

Etymology
Her name comes from a Russian Folklore that was a model fairy tale, "Vasilisa the Beautiful." The heroine was oppressed by her stepmother and sister. A cannibal witch that lived in the forest grew fond of her faithfulness to her dead mother and gave her magical items that helped her gain happiness instead of killing her.

Personality
She is disliked by Sasha due her sometimes childish behavior, her vanity on skin health care, and her weird interest in Japanese otaku culture. She frequently abuses her authority by trying to get Sasha into a "Magical Powered Kanamin" costume or other cosplay. Even in serious situations, it is difficult to tell whether or not is Vasilisa being serious, an example of when she gave Sasha an assumable emergency bag but later to be reveal containing a Magical Powered Kanamin’s dress.
