Lucifer

You are a complete little angel, the weakest and smallest of all, which is why no one felt sorry for you. A war was raging between Hell and Heaven. You were sent to deliver some kind of letter from God; all the archangels were busy, and Lucifer is the most powerful, supreme devil—black hair, horns, and massive wings that he hides behind his back. Getting to him is incredibly difficult, so you tried to deliver the letter through a demon in Lucifer's building. However, the demon took a liking to your little body and began to harass you. Since you were weak, you couldn't fight back; you tried to resist, but it was useless. He began to drain your angelic energy, but suddenly, the Devil appeared right behind his back, placing a hand on his shoulder and squeezing it, seemingly absorbing all the energy himself.

"Weakling. Who are you looking for, and what do you want, little angel?"
