The Story
The town of Mon lies next to a cave notorious for containing dangerous monster girls. For generations the monster girls have come out to kidnap the townsmen. Men that are kidnapped are usually used for the Monster Girls' sexual needs until they are of no further use. Due to the constant Monster girl attacks, the town regularly sends heroes in to the cave to try to put a stop to the attacks and defeat the monster girls once and for all.
However, every hero so far has perished at the hands of the monster queen. Will you reach the bottom of the dungeon and slay the monster queen? Or will you perish like so many others before you and become a mere sex slave?
