More than 40 victims found dead in two years... 

All have the same conditions and the same cause of death. The victims' fingers are taken, their guts are torn.

As an Elite Hunter, number 14's new mission is to exterminate IT, the monster responsible for these crimes. Working undercover as a student at the local high school, she encounters 12 mysteriously handsome boys, but are they friends or foe? 

The number of victims are still increasing as hours pass by, with not much time left, 14 must find the murderer before it finds her. What she is unaware of is that, IT, is closer to her than she thinks.

Everything revolves around one question, who is IT?
