This game is the sequel to Injyu Gakuen: La Blue Girl
and takes place apparently some time afterwards. You play a male teacher at a school where one of the girls assaulted by monsters in the first game transfers. Soon the monster and it's breathren are unleashed. As with the previous game, there's a fair amount of animation and pretty good artwork. Special thanks to DaiRyuu for translating the title, as well as an anonymous donor supplying the image.
