Devilish Girl is a character from The Legend of Zelda: A Link Between Worlds. She runs the Treacherous Tower, a challenge dungeon located atop Lorule's Death Mountain. She appears to be the Lorule counterpart of the Bee Guy.
The Devilish Girl waits for contenders to come and challenge the Treacherous Tower's various levels of difficulty for a fee, though she does not expect people to return alive. She has a cheery personality, often shouting in joy over being given Rupees. The Devilish Girl gives Link various things for completing the Treacherous Tower, such as a Piece of Heart for beating the Intermediate level. She also gives Link upgrades to his Lantern and Net. If Link completes the Treacherous Tower with a faster time than he previously did, she rewards him with Rupees.
