Haze

"The world is filled with things we can't see. Astral projections and ghosts they are usually called. But they have a name too. Denizens, things that are alive just like us. And really, you just have one thing that keeps you "alive". An orb known as Existence. But for the Denizens to live, they too need Existence. To get that, they need to feed off us. And when there's no more Existence in a being, they disappear. Denizens can be found in many different forms. Your worst nightmares or your best dream.but to every thing, there is an opposition. The Hunters of Denizens, also known as Hazes, are the only people who can kill the Denizens. Hazes have no Existence or have an infinite amount of Existence. There are two types of Hazes: Silver and Crismon Hazes. Silver hazes are contracted to a Lord of Aether and get rid of Denizens by extracting their stolen Existence into the air,where it disappears. Crismon hazes are contacted to a Lord of Flame and destroy Denizens by burning their Existence into disappearance. Hazes can be classified by their title or color of magic. Hazes, Denizens and Lords aren't the only magical creatures here. Mages, a lower level of Hazes, also exist. They rid the world of monsters, like Bigfoot and the Kraken. We mortals are mere torches of existence. Hazes and mages could be your anyway people. Best friends, enemies, and even classmates. Lords and Gods exist in their own worlds. Hazes have the power, or what you call magic, of their contacted Lord. Gods are a being more powerful than the Lords. Some known titles are Timekeeper, Lady Aether and Cloud Keepeer. An analogy for this coverage is : Mage : Haze ; Lord : God ; Human : Denizen. To cover this, the world we know of is just an illusion. Adding on, you mortals are the true ghosts here."

A Haze (ヘイズ) is a former human that has made a contract with a Lord to gain power. A Haze's main job is to protect the balance of the world, which means destroying all Denizens that devour people to take away their Existence. They are simply called as the "Hunters" (討ち手).Most Denizens cynically call them the"Tools of Destruction" (討滅の道具) or "Same-race killers' Tools" (同胞殺しの道具). A Haze normally becomes one because they wish revenge on a being that has devoured or taken something away from them.
