What happens when you take a powerful invisibility potion and place it in the hands of a total pervert? Hapless loser Mie goes from dud to stud overnight with the ability to make all his hottest dreams come true! For starters, he can now ogle all the lovely ladies inside the bath house - heck, if he plays his cards right, he can even score a home run or two! But that's not all. With this magic medicine, he can peep around the women's academy at will, get even with his slut of a manager, and even spend a hot and steamy night with the girl of his dreams. But he's gotta be careful: each dose only lasts an hour, and who knows what'll happen if he gets caught!
