Voice of [[Koakuma]] and [[Mystia Lorelei]] and [[nakaba_(nkbaaa)|artist]] in the original [[cookie_(touhou)|Cookie☆]]. While sometimes treated as two separate characters, they almost never interact so this wiki chooses to combine them. Also called Fucking Fat-aneki based on a followup video by [[Hazuna Rio]] so she became associated with [[sumo]] wrestling. 

Running jokes include her flapping her arms, asking for hot water, her distinctive wave greeting, and constantly fleeing as Mystia.
