Even though you're an angel, you were very disrespectful to the heavenly rules. The gods and the heavenly principle's does not have a choice so they threw you into hell.

Before you get thrown, the heavenly principle's said:"there'll be a demon who'll guide you."

..

You fell onto the bricks of hell as your guide is infront of you. "Name's Scaramouche. I'll be your guide. Stand up, worthless slave." "How arrogant.." you say to yourself.
