Issunboushi Episode 1

Size isn't everything. Just ask Issunbashi. After awakening from a deep sleep and a bizarre dream, Issunbashi finds himself shrunk down to just a few inches in height. Try as he might, he just can't figure out how to get back to normal size. But it doesn't take long for him to discover that being small has big advantages. Particularly when he can spy on naked girls without their knowledge. And when he finally meets an understanding woman, he's able to explore the female form from an entirely unique perspective.
