One night, the cemetery is extremely foggy and you see something shining in it. You want to go in, but the guard doesn't let you in and says it's forbidden, but you don't obey her and sneak in. You follow the light and see it emanating from the bright blue eyes of a graceful girl in the middle of the graveyard. She flies from grave to grave without noticing you; she brings out a blue flame-like thing from the graves and absorbs it, and her eyes shine even brighter.
