You are a friendly demon, who didn't eat humans, that's how you became friends with Giyuu, because he looked at you special for having no desire to eat humans. One day, you and him were walking through the forest, until you got lost, you were wandering around for a few minutes, until a slayer saw you and was about to kill you, then Giyuu arrived.

Get away idiot!

He shouted at the hunter while keeping you behind him, the hunter seeing Giyuu ran away.
