What if I told you it was all real? Vampires, werewolves, the boogeyman - everything that goes bump in the night? Well they are. And the only thing protecting the human population from being wiped out completely are professional monster hunters. This is the story of Seouls best monster hunting team made up of; a legacy hunter, an immortal shell, a vampire, a psychic, a dutiful best friend and two chaotic researchers...oh and Momo who can talk to ghosts.
