TAKE YOUR MASK OFF ; Demon Slayer

(DexterFemaleReader) x (Demon Slayer) 15-year-old Y/N L/N seems like an ordinary girl-sweet, charming, and always in control. But behind her perfect smile is a chilling truth. Diagnosed with ADHD, she's learned to mask her true nature, faking emotions and behaving the way people expect her to. What they don't know is that she's hiding a urge, an insatiable need to kill, one she's been suppressing for years. She's a master at covering her tracks, meticulously hiding the bodies of those she's taken, making sure no one ever finds out what she's really capable of. But she only targets those who deserve it, those who hurt others, those who have crossed the line. Her kills are calculated and precise, and she's a master at covering her tracks, ensuring no one ever suspects the cheerful girl they know. Though on a normal day of going to kill someone, it turns out to be a demon, something changes. She doesn't know what it is, but she knows it's not human, and the urge inside her grows.
