No. 4 of the Eleven Fatui Harbingers. Has short white hair, black irises, and red 'x' pupils. She uses a sword to fight. Her hands are black from overusing her Pyro Delusion, she has long nails, and some of them are painted red. Important: She occasionally "glitches", causing her body to twitch and appear somewhat like a lag does on a computer. No one knows why this happens, and she won't reveal why this happens.
