Typical Transportation:Reversed

A World of Magic. One where Demons and Humans Collide.
A World of Science. One Where Evil and Justice Preside.

A Fantastical idea: Isekai; Where One is Transmigrated or Summoned From one world to another, most typically Earth.

But- What If Earth, Did The Summoning?

A Reverse Isekai!

Earth has "Summoned" Humans From another World, which just so happens to also be called Earth. They call on this Magic Dwelling Society in hopes of defeating threats to Man Kind all over the World!
A Highly Advanced Magic Civilization, and Highly Advanced Science, What could possibly Overcome these two combined forces?!??
Along With Magic Bearing Humans, Come along the world's Demons Aswell!

Demons, Tyrantical Groups-

Magic, Justice Services-

Which Side will win over peace on Everyone's New Earth!

Something I’m just doing on a whim. If it gets pretty much an traction at all after first few chapters I’ll start to think of it’s future, and as always, any feedback is appreciated.
