That's cute, but I don't believe monstergirls and gods like her really want that scenario to happen at all as the consequences are far more greater than they appear to be at first glance, and not to mention too many variable could play at once. They would also be saddened at the number of innocent lives lost, surrounded by subhumans in the world destruction.
I won't lie though, I do daydream every day about such a scenario like that on a global scale - capable of opening super portals on our world bringing in monstergirls in order to heal the world and humanity alike, it resembles like a generic JRPG but it works. I have a scenario that doesn't involve any wars at all but it's still edgy as hell.
