There was a demon attack on your village by the time the demon slayers came your family was already dead along with a few other people's family

There a bunch of demon slayers along with a bunch of demons you were sitting on the ground crying as a demon slayer who looked like a demon literally ate a piece of a demon then killed it. You were scared still after all the demon's were killed and you were scared of Genya since he looked like a demon
