Humans are no longer at the top of the food chain. The creatures known as "Insectors" hide amongst us, using their supernatural insectile powers to prey upon humans. Miseong, a seemingly ordinary high school student, is also secretly an Insector. But unlike others of his kin, he directs his powers not at humans, but at Insectors instead. Will he maintain control over his abilities and use them for the good of mankind, or will he succumb to the monster within him?
