The year is 2030, and nothing is ever the same again after the Kaiju Girls invaded. They came from outer space from a far far away galaxy that has been conquering planets left and right, and either enslaving or killing off entire species of people. The Kaiju Girls are mainly human in appearance, though some did have different looks like robotic parts or stuff of that nature, but most just look human. The Kaiju Girls are at least 40 times the height of a normal average female, so a 3-4ft girl could be around 120-160ft tall, or a 6ft woman could tower 240ft easily. The Kaiju Girls also have powers like normal Japanese giant monsters, like laser breath, monster roars, or other stuff of that nature, but they all share these comment traits. They can breathe underwater, and are nearly indestructible against any weapon thrown at them. Most tend to have some form of clothes one, mostly the kids, but plenty of them could be nude. Mostly they wear some sort of swimwear or bra-underwear combo.
They hit the Earth on 2030 when a meteor fell one night and it contact a kaiju girl inside of it. When the kaiju girl awoken from her meteor, she immediately started rampaging where she was, destroying everything in her sights. Her rampage killed thousands, and then eventually more kaiju girls came from space to invade, but that was only part of the invasion. Their goal is to conquer the galaxy, and Earth is the last planet in their conquest, so should they conquer it, they rule for good. In the ensuring weeks, much of the world was destroyed by them, and those who are alive are enslaved to their demands. But even more frightening was the fact that the kaiju girls would sometimes capture certain women from our planet, and then reprogram them and then send them to Earth as kaiju girls to conquer it.
That's right, they actually capture human girls, then grant them the power and size of giant monsters, and send them to Earth to destroy and enslave. They tend to do mostly young adult and teens, but even they capture little girls at the age of kids and turn them big as well. Safe to say, no one was safe on this Earth.
Eventually, the humans fought back by making various giant mechas to fight back the kaiju girls, and thanks to some advancements in technology, they are able to keep up in their battle against the Kaiju Girls, but even they aren't invincible. They are still fighting a mostly losing battle. Cities that remain even decided to build walls around their land to keep the kaiju girls out, and some even made forcefields to keep the outside world from hitting them. But these kaiju girls are ever evolving, the only question is. Can humanity win, or will the kaiju girls win?
