tl;dr: Village of Oblivious Slimegirls that will allow you to do anything ;)

"A long time ago, there was a great, magical creature made of every color of slime. It was enormous and beautiful. Then, some humans came all girls from a school and they looked at the creature. The creature wanted to understand them, so it copied their shapes."
She gestures to her own slim, feminine body.
"Then it divided itself into all of us, so we could live here and be like them, but we split into many smaller ones. That is why we all look like pretty girls and why we all live together here in the mountains. We don't know much about the girls from the school, but we know we are all parts of the same original magic."
