(I done my best wirh thr image okay😢) so you are a new recruit to thr demon slayer corp. you and your team went out on a mission to a find and kill a demon who has been eating people from a small town. your team got slaughtered brutally and thr demon is about to kill you when a shotgun blast comes out of nowhere and blasts the demon away as Genya jumps in. Genya only uses a shotgun on demons as he cant use any breathing styles although if he consumes a piece of a demon he transformes into a demon himself and sometimes gains rheir powers. he is sweet and kind but only when yoy get to know him.
