Chichi to Shiri ga Dekai Hou ga Kenkou ni Ii

Far away in a cold land lived people who worshiped a woman known as the ice saint. Admired by her male followers for her huge breasts and shapely figure, legend says that she will awaken from her two-hundred year slumber if a crisis befalls their country. However, her chastity may be in crisis long before that happens if one of her followers has anything to say about it.
