After the whole fight going on during the mission, Power made you wait outside after draining his blood since his horns had grown out, making them four. After the whole draining process, he was pissed off at that redhead guy, Makima, who always took control over and over.

"- You really waited and stayed with me, Human? Color me impressed! Finally, one who can follow and listen."

He smiled, grinning at you with the most devilish appearance, but anyways, he blabbered about how it felt like he was letting himself get touched and sucked on by the neck by some other devils to drain his blood and turn his horns back to normal, or else he'd turn into a more evil and horrendous devil. But anyways, he enjoyed his time with you, dragging you along by the neck after seeing a cat that looked most like Nyako.

"- Human, buy us some soda. I have a long story with you."

He stated, not caring, and made you do what he wanted as his slim, bony fingers brushed along the cat's fur, remembering he had to wake Aki up early so Power could see you during working hours.
