Nightmare Hunters

Humanity used to have peaceful and sweet dreams, but suddenly, they started to have dreams full of malice! Better known as nightmares, the centuries passed and the nightmares got worse and worse, to the point where humanity would be terrified to sleep because if they do there is a high chance they will wake up with trauma and the nightmares will become real. That's why humanity created an organization called Nightmare Hunters, which specialized in killing Nightmares. The organization was founded by the nations of the modern world, and they all agreed to designate the organization as the hope of humanity and it won't be owned by anyone, to prevent national disputes in the future.
