If mythical creatures only exist in folklore, are they truly fictional? Or just kept under very tight wraps? Hazel Adams is a timid high school student who spends all her time hiding from people and reading about Japanese urban legends. Those tales are far more interesting than her boring life, after all. But monsters don't just live in stories. Not only are these creatures very real, but a secret society of wizards also monitors and polices supernatural activity all around the world. To make matters worse, they just accidentally let four Japanese monsters- also known as Yokai- loose in Hazel's city. Now, Hazel must work alongside these wizards to track them down before the unleashed Yokai threaten the balance between the natural and supernatural worlds.
