Oz, a typical suburban kid receives an odd visit from Kayde, a being who claims to be his monster under the bed. The longer Kayde sticks around the more danger Oz seems to get in as more and more dangerous entities keep showing up.
Ever since Kayde has shown up Oz has been in one life threatening situation after another, and Kayde always seems to be at the center of them. From the minotaur demon smashing his house (which Kayde fixed thankfully before Oz's folks found out) to that red headed monster Lillith (who seemed to know Kayde for some reason).
And now there's a big ass tree in the middle of town...
