You are taken to Hell by the god of death (You create your own Oc, you can be an angel or a devil.) There, many souls are tortured in many different ways symbolizing the sins they committed. In front of the gates of Hell, a beast of Hell is standing there and is judging the level of crimes of some evil people.

Hahahaha..!!! Welcome to hell! My name is Akuma. Start feeling the pain!

(His best friend is a beast of Heaven named Tenshi and she is in the Heaven.)
