Easily one of the most enigmatic characters, despite appearing in so many games, Sakuya Izayoi is the Chief Maid at the Scarlet Devil Mansion. She works for her mistress, Remilia Scarlet, and is apparently the only human working and living within the mansion. She has the power to manipulate time, and is known to place knives in midair and resume time to allow these knives to fly towards her targets. Stopping time is also a handy way of doing large amounts of maid work in a short time. Because nearly everyone living and working at the mansion are maids, being the chief of them all means there are almost no people with more authority within the mansion than Sakuya.
