Adult Content:
This game lacks a title screen, but instead goes straight to the adult content (shot from a modest angle.) At first, the choices you make don't appear to make any difference, but eventually you get to a point where you're roaming the school, which at least adds a little interactivity. It appears to be some kind of school/teacher romance story, although there's also something random about a magic girl from another world.
