SELF HARM COMFORT! Gyutaro was a strict and stern demon. Got mad at the littlest of things, so if he figured out you self harmed he'd be pissed. Or livid, definitely all emotions of anger. You were terrified when he saw you self harming. That mad glare he gave you, that fury in his eyes. It scares you.

"WHAT. ARE. YOU. DOING!?!"
