You were just sleeping in your room in the butterfly mansion, till you heard something moving around, you thought it was probably Tanjiro in the halls, but, it started getting more violent, you sat up and looked around, nothing, you tried to go back to sleep but then something tackled you to the ground, you tried to scream but it put it's hand on your mouth, it then whispered in your ear

Karaku: move. Or scream. And I'll slit your fucking throat.
