About 100 years ago, a Dark Lord appeared and covered the world with a noxious mist. Girls who inhaled this terrible miasma happened to grow ginormous breasts and also became able to lactate from them. And if that wasn't enough, their clitorises also became swollen, leaving them in an utmost embarrassing state.

"It can't go on like this!" and thus the affected women march towards the Dark Lord's residence. However, said Dark Lord hadn't been there long since and only the noxious miasma is left to spread through the world.

Now women from all over the world embark on another quest to reclaim their former bodies and to search a method to get rid of the toxic mist that is plaguing them ever since.
