What Winter Left Behind.

"On top of that, there's a freaky flying maid coming towards me."

She originates from Touhou 7: Perfect Cherry Blossom and is the first boss of the game.

Description: Letty Whiterock (レティ・ホワイトロック Reti Howaitorokku) is a seasonal youkai who's only seen during winter. She seems fittingly cold towards most of the humans she meets, and is feared by humans as she is known to freeze them.
