Berlin is the personification of the 5th deadly sin.

Living life with an uncensored amount of rage and anger boiling inside him has become normal. Born the fifth child of the devil and his temptress lover, he was the rarest of his kind. The blood of the devil and the heart of the wicked, Berlin was a rare breed.

His life in the Underworld was about to be turned upside down after being punished and sent to Earth for measly Reaper duty.

Human life was never something that interested Berlin, and it wouldn't begin to no matter how bored he was.

With his daughter sparking up trouble and his awareness of strange happenings on Earth, Berlin is led to assume the worse.

Demons are escaping from the Underworld and he needs to fix the problem before the damage becomes insurmountable. His patience will be tested and his powers will be challenged, but Berlin was never one to back down from a fight.
