Translation Notes
Everything is translated except for one command in the battle system that is handled through a script.
It's a combination of my limited Japanese, machine translation that is checked for accuracy, and online dictionaries.

Sex battle against an army of men using your sex techniques.
You'll be fine if you climax from regular enemies, but if you do from stronger ones, you will be creampied and lose.
Search a school that's turned into a labyrinth, and make your escape while trying to avoiding these sex crazed men.
