Diangelion

The Demon Lord of Destruction with superior power and her most loyal follower.

Lu was slowly recovering her demonic powers until the day the El was restored. A dark demonic energy surrounded her body, giving her the power of absolute destruction. Ciel accepts the overwhelming demonic energy from Lu, dutifully following her violent tendencies as her loyal shadow. They go on a hunt, to find a new toy for the Demon Lord of Destruction to play with again.
