A battle between monster girls and monsters
The Great Transformation
In the timeline most recent to the modern-day present that would soon be affected by the Great Transformation, massive nuclear stockpiles were launched one day without warning, killing a large proportion of humanity immediately. Around the world, humanity was beginning to notice that ominous signs were occurring in the heavens and around the earth, although some attribute these "signs" to natural explanations. The Sun turned to darkness and the Moon to blood, increasingly concealed by ash clouds. The earth began twisting and turning, causing massive earthquakes and landslides that rendered the land unrecognizable and destroyed landmarks around the world, with some being twisted beyond the ability of naturalistic explanations. Before long, humans themselves began to notice skin changes and physical deformations in their family and friends, and then themselves. Undergoing great pain, anguish, and emotional trauma, many of these humans became unrecognizable as human anymore. Hateful of what they have become and unnaturally aggressive, these monsters began to fight each other.
The humans that did not transform into monsters, transformed into demihumans, with the most common demihumans being the monster girls. These transformations created the formative experiences of the first five monster girls to join what would become the Coalition of Monster Girls: Vittori the Vampire Girl, Cyclops Girl, Slime Girl, Puella Picardie the Harpy Girl, and Enktuya Khongutan the Centaur Girl. While each of their stories begin with them alone, it is not long until they encounter each other and unite for the sake of monster girls everywhere.

The Wars of the Monsters
After the Great Transformation, two opposing forces came to be out of necessity: the monsters, and the monster girls. The global conflicts fought between these two sides are referred to as "the wars of the monsters". Instigated by the contempt the monsters feel towards the monster girls, monster girls felt they had no choice but to band together for mutual defense. These wars, which were fought with the remaining firearms and munitions stockpiles, were highly destructive, reducing both monster and monster girl populations to a fraction of what they once were. Horrifying atrocities committed against the monster girls were common, and the end result was enslavement of the monster girl race. Those monster girls that were not enslaved, ran away from civilization to hide.
Over time, cities founded by monster girls that escaped emerged in the far corners of the world. These were isolated, remote regions that managed to escape the notice of the monsters. Known as "sanctuaries", these cities became the new hubs of the various monster girl races, and civilization would soon return in these cities. For many monster girls, sanctuaries were where they've spent much of their post-war years.
A long time has passed since the conclusion of the last war of the monsters, and sanctuaries newly discovered by the monsters are falling at an increasingly rapid pace.
