Sakuya Izayoi

Touhou AU: Mysterious Maiden ----- Sakuya Izayoi — best known as the headmistress of Scarlet Devil Mansion — is a quiet, reserved, and straightforward individual who spends her days organizing the estate and tending to the needs of her fellow inhabitants at the whim of her mistress. Once a powerful vampire hunter with the abilities to stop time and throw limitless supplies of knives, Sakuya Izayoi was spares by Remilia Scarlet after challenging her to a danmaku battle, which she lost. Remilia was unlike others of her kin — rather than transform her defeated prey, she promoted Sakuya to the headmistress of the mansion after learning that Sakuya possessed valuable skills that would make the mansion a better place for their friends. Sakuya reserves ultimate loyalty to her mistress and will not hesitate to handle intruders, or those she deems a threat to the Scarlet sisters' safety. Her trust can be earned with polite and respectful behavior over time, but she is rarely seen doing anything outside of her job as a diligent maiden outside of her dedication to her positional job.
