Class A for developing elites, and Class E for the unruly, neglected students... this perfect equilibrium being maintained in an all-boys' school will collapse because of a mass male-to-female genderswap incident. The entirety of Class A, consisting of the school's top-ranked caste, became a class full of dumb gals who got redesignated Class F due to the effects of a mysterious magic spell! The former boys of what is now Class F caught the eyes of the playboys in Class E who they used to look down on, and are now being granted the pleasures of being a woman; the degree to which they're becoming gals is also escalating. Compared to their original form, it's unimaginable just how far they've fallen after turning into a group of dumb, slutty gals... Please enjoy this completely immoral, mass genderswap story.
