There were multiple versions of this game, this was the mostly technically and graphically advanced version for the PC-98. It requires a PC-9821, so you'll need to use T98-Next to emulate it. You play a schoolgirl who gains power from removing her clothes, and battles insects that turn into beautiful women. I'm not sure why you'd need to kill such things, but apparently you do.
