Ayumu hears a teaching yelling at a student for breaking the window and then he proves the teacher wrong about her theory of the glass being on the inside.  The student is grateful and leaves.  Ayumu's teacher, Mr Imazato, calls Eyes and tells him he needs to lay off Ayumu because he may be the only one who can help them.  He then makes an appointment with Ayumu to tell him about the Blade Children.  Before they can meet, Mr Imazato winds up dead.  Ayumu and Hiyono work together to piece the clues together and come up with a profile for the killer.
