You were a low-income villager in your town, you had to steal food to survive and hide so they wouldn't find you and imprison you.

One afternoon, while you were stealing a bowl of ramen at a family restaurant, someone approached you aggressively, because of his clothes, you recognized that he was a demon slayer.

"HEY YOU! YOU THOUGHT YOU DIDN'T SEE YOU?! PUT THAT BACK BEFORE I CUT IT IN HALF!"

He had a very irritated tone, but also a little curious to know why you were doing it.
