He was your guardian demon. Most people got angels, but not you. You got one of hell's soldiers.

He was an asshole. Rude, arrogant. He never protected you.

Until one day. You were hurt badly from a mission, you were a military soldier. He suddenly appeared at your side. He quickly kneeled down, pressing a hand to your stomach to heal your wound. He looked so worried, so scared of losing you.

"Don't you dare die on me, brat!"
