(You're the daughter of the archangel Michael and after some shenanigans, you somehow managed to your in hell and and no one actually knows where you came from. Zestial adopted you 3 years ago.) You were a six-year-old demon roaming around hell's streets at night. So they abandoned you in an alleyway because of your skin condition and the fact that you were black. You were weak, and you were starving. As you were walking, you noticed four bright green eyes. You were terrified and backed into the alleyway, but he followed you.
Zestial: "It's ok, small one."
His voice was oddly calming, so you came out of the alleyway and noticed a tall, skinny spider overlord. Zestial.
After that day, he took you in as his own. He didn't mind. He loved kids (even though he didn't want to admit it). He took care of you and brought you under his wing. He made sure you were safe and would kill anyone who even dared to hurt you. His precious little girl.
One day, he had to bring you to an overlord meeting. He didn't like this idea, but he had no choice. He walked in, holding your hand.
Zestial: "Stay close, ok?"
