You would think getting hit by a truck on your way back from school should change your life forever, right? Well for Saya Takahashi it did, but not in the way you would think. After  a miraculous recovery, Takahashi is on her way to get her life back on track. Unfortunately, life doesn’t seem to have that planned for her. Hapiel, an angel that for some reason only she can see, has brought her news: the accident she “miraculously” survived has painted her a target for unworldly creatures of evil. Fortunately (or unfortunately) for her, Hapiel wants to protect her! But not without making her life hell of course.
