Asaba Naoyuki is an ordinary high school student. As a member of his school's press club, he's just spent the summer camping outside the local military base, in hopes of seeing the UFOs that are secretly kept there, according to local legend. Returning to school, he meets a strange girl, Iriya Kana, and gradually comes to realize that she is more than merely strange - and that a dark secret lies beneath the world that he knows.

My first impression was "Oh, i hate how the main character is drawn". I decided to let it be, that i wouldn't let such a minor detail smuther my enjoyment, since i had heard and read good things about this. Fortunately, he was the only eye-sore. The art was pretty well made, and in the end it was one of the best qualities of this ...
