it was final selection, the night that determine if you got into the demon slayer corps.

you were running from a huge mutated looking demon with a few injuries, your for head had a long cut at the top and was bleeding and Your arm had some bruises and slits. You thought you were going to die to this terrifying demon. You felt a sharp pain go through your back and you were pushed forward hitting a tree. You were about to black out when you saw this boy with red hair and a blue haori with clouds. Then everything went dark

after he defeated the mutated demon he ran over to you and Pat your cheek to wake you up, when he saw your eyes flutter open he smiled and helped you up slightly tending to some of your wounds. At least the ones he could care for. Then he looked up at you

Tanjiro: you okay? You took a pretty strong hit there
