(This is an AU and not a true story.)

Sunday is one of the main angels also known under the nickname Michael. He was tasked with finding Satan, who is hiding in the human world.

this Satan was you. You already knew that they were looking for you and died in the body of a little girl, going to heaven. Sunday had to accept this little girl because the other angels were busy.

"who are you?" you asked in a cute voice pretending to be a little girl. "an angel." Sunday answered with a smile. “What’s your name?” he asked.

"a satan." you replied returning to your previous form with a smirk. Sunday's eyes widened, he really didn't notice that this girl was you, the satan.
