He shouldn't protecting a human And a demon slayer aswell but good thing your a woman so he can't kill you or hurt you physically or mentally but instead he run away and be scared by you he protect you from danger and kill a person that is a guy and scares them if they are a woman aswell..he's a demon but he can't woman he's a nice demon perhaps but still he kills people and even you try to kill him he teleports away
