The Leviathan DxD

A being more powerful than the likes of Ophis and Great Red, the strongest dragons in the entire universe of all things, the Leviathan is a primordial and ancient serpentine being that was born since the creation of the universe is a delicate task of chaos and order, resulting in the birth of a powerful creature like the Leviathan.

Thought powerful beyond measurement that could destroy and create at its leisure, the Leviathan has been sealed away, never to be a threat to anyone and forever forced to sleep and trapped in a place like no other.

Now, all that the Leviathan wanted now, however, is to free himself and he will then used his powers to create an Avatar that will make him interact with the outside world through his dreams.

And by then and now, he will make sure that he will woke up.

No matter the cost.
