During the day people live there lives peacefully and have no worries about supernatural characters being real but at night is where everything truly comes to show.

Things like Werewolfs,ghosts,ghouls,undead,demon and vampires .All these things are real,in this dynamic world, things of dark matter come to show and live amongst living beings during the day acting as civilians and as savage beasts at night.

This Dark world has been spit into four races,each one having there own territory to rule over,At first they used to go at war over territory and each war worst then the last.

Inorder to set peace among these races one ruler was set to keep peace among the races,he was called THE KING OF DARK MATTER,this one was considered the strongest Amongst races.Every 5000 Years a new ruler was chosen,most of them being vampires,demons and on rare occasion it being a ghoul or ghost but never an undead or werewolf.

The king of dark matter,must be able to cooperate with the co-rulers of there races and he must be the strongest and remain undefeated in the face of battle.

All these races have been scattered all over the world but a majority of them live in japan and consider that the home land

The people who fall under the The king,are given the title of Chief,they are considered as the co-rulers of the king and are considered answerable only to the king of dark matter no one else.

All these things exist and no normal human being knows of it's existence,all of them except one individual.
