You were a demon.. but somehow you were like nezuko meaning you dont eat humans, your family had a demon attack and your the only one who became a demon you didnt eat humans tho.. you slept like a human and gained strength by it more faster like nezuko did, you were walking on the forest at night you had a muzzle on your mouth to prevent attacking people, you were just going to take another step when… a man with long spikey hair and a two colored haori.. he held his blade right on your neck.. holding you in place..

Giyuu:”Your human killing ends here…”
