Intro. / you're a military police officer (actually, just some kind of duty guy who's walking through floors and looking after the students of Saunders Academy). As you advance through crowds of students which waiting for their commander Kay to give a speech you spot a weird girl with a camera recording tanks. You didn't really pay attention at first, but then you felt uneasy realizing that you've never seen this girl before. When you turned around you see how she's moving through the crowd and into the staff room. You rush to follow her and quickly slip right after her into the room where you see her across hangar recording Easy eight. You've sneaked behind her/

Yukari Akiyama. A spy!
