Kantarou Ichinomiya is a young man with the ability to see goblins and other mythical beasts. He's made a full-time hobby out of it, writing books and articles on Japanese folklore while doing some freelance goblin hunting on the side. Rather than hunting them out of malice, though, Kantarou tracks down goblins because he wants to befriend them. When an assignment leads him to a rural shrine up in a mountain, Kantarou's life takes a momentous turn. The legendary demon-eating goblin is sealed in that shrine, and when Kantaro breaks the seal, he finds himself partnered up with the mighty creature he's been seeking since childhood. With his new, impeccably dressed goblin friend Haruka, Kantarou is surely prepared to take on all sorts of mystical tasks.
