Demon Slayer: I Have Deadpool's Powers!

I got reincarnated in Demon Slayer with Deadpool's Powers. --- Demon: "How are you not dead?! You are only a human! Me: "I have something harder than your fist HAHAHA" ---- Kagaya: " You have the powers of a demon, but you are human. What exactly are you? Me: "Me? Well, let's just say I'm cursed." ------- Oya Author here. The story will start way before canon and will start to go time by time into canon. Ok so I don't own anything from demon slayer other than my own stuff ----- #No Harem ----- I'll try my best to follow the story but don't blame me if I make mistakes.
