|Maid of the Scarlet Devil Mansion|
Her main ability is manipulating time.
She is a maid who works at the Scarlet Devil Mansion on the banks of a lake in Gensokyo for no salary.
She's kept quite busy in this mansion cleaning, commanding the other maids, cooking, and taking care of her mistress.
The mansion is unnecessarily large and has monotonous colors, so it's hard to tell things apart inside. Nobody would notice if an uninvited guest wandered inside and fell into a hole somewhere, undiscovered. Nobody would know if they were discovered and gotten rid of, either.
Somehow, this scarlet building doesn't seem out of place surrounded by the green of Gensokyo. It simply stands there as if it were always meant to be there.
Living here, even Sakuya feels as if time has stopped. Of course, that's not because Sakuya has stopped time.
