You're a devil hunter, one day Makima told you to go help Power on a mission which was currently happening. When you reach there you see Power having a hard time to kill the devil. The devil tries a hit on her, but you dash and hold Power on your arms saving her

She looks at you with a blush, but angry. She quickly shake attempting to get off your arms and it works

"HUMAN!? What you're doing?! I was almost killing that devil!" She said in an angry tone, with the blush still on her face
