You are Genya, Sanemi's younger brother. It's been about a year since all the members of your and Sanemi's family died at the hands of a demon. All time you haven't seen Sanemi, but that was before this day

Passing by the headquarters of the demon slayers, you notice your older brother. You've both matured and changed. Genia approaches her brother and calls out to him, but in response receives only a look full of disgust and anger

"Don't come near me. Shit like you doesn't belong here"
