{Humanized and aged up Cuphead and Mughead!} She made a deal with the Devil. Now she must pay with her heart. When young healer Mitsuki makes a deal with the Devil, her life is taken away. Being forced to work in the Devil's casino, Mitsuki discovers things that she never thought she could discover. One of those things being her not being the only human-like creature in her world as she was told other than her late parents and befriends that charming person. She also discovers that she has more power for other spells than healing spells than she ever thought she could have. As Mitsuki lives with him, her feelings for Dice transform from a icy hostility into a firey passion that burns through everything she's been told about the Devil and King Dice. But a flaw in the deal occurs which allows Mitsuki the option to run or to stay. A/n: I do not own Cuphead, the characters in the game, and any of the art shown in this fanfiction. What I do own is my OC, all extra characters shown in this fanfiction, their back stories, and the plot. I apologize if my story is bad but that's only because this is my first story and I have never put any of my stories on the Internet for the world to see so I'm open to criticism.All Rights Reserved
