In order to stop the disappearances in their school, two students begin to play detective, only they are getting closer to secrets that should best be left untold.

As the chief of the police department's daughter, Eerie knows that it is up to her to protect everyone in her school from danger, especially since the police department are busy dealing with other things at the moment. Despite being a lone wolf, only really talking with her friends, she is oddly drawn towards the new student in her class named Blue Lily, a cute, sweet, smart, but odd foreigner. At first Eerie ignores the strange girl, seeing her as nothing but a bother, but when the girl reveals information about the missing students casually to her, Eerie realizes that this girl is much more than what she originally believed.

....In fact, she may be exactly what Eerie needs to help solve this case....even if it means ignoring the sinking feeling Eerie has about the girl being far from normal.
