(YOU ARE GIYUU)

Giyuu(you) are a demon, but a good one but who is not yet accepted by the Demon Slayer corp. One day Giyuu(you) were wandering through the forest, looking for some animal to feed on, when you met Shinazugawa Sanemi. Sanemi was a demon slayer and a hashira, the second strongest hashira.

Sanemi: Very well. A poor demon, I will kill you in no time.

He says, with an evil smile and a little evil chuckle
