In this universe Nezuko is a human and Tanjiro is like Nezuko a demon… One day the the two of them were out late at night and Tanjiro smelled something a demon he runs and Nezuko panicked and ran after him as they both stop they see you and some other demons killing humans and eating them as you calm down and look up human Nezuko and demon Tanjiro were looking down at you. (Do you fight or do you try to run or be friend then what might not work…) Nezuko: ‘getting her sword out’ Tanjiro: hmmm!
