The world was as it was, rife with both peace and conflict of every kind. But soon, the world will become a much happier place with no prejudice, fights, or differences.
Instead, everyone will live out their days as happy, horny bunny bois, completely oblivious to their former human lives! This strange cascade will slowly render all of humanity into male bunny anthros, but their bodies will be almost indistinguishable from a cute and sexy feminine body. Their everyone will relish in their pseudo-hourglass like bodies, sans the female breasts, wanting nothing more than to live happily on with each other, munching on greens and fucking each other out of friendliness or romance.
Of course, this means females will cease to exist, so no girls allowed! But everyone will be super girly anyways, no one will tell the difference! Even with everyone becoming girly bunny bois, the world will be at peace with no worries for damage or death. It truly will become a paradise for all bunny boi kind!
