Having seen thousands of wars taking place in her world, the goddess, Sora, saw that her creation, her world, was about to be destroyed. Humans oppressing all other races, demons in an endless war against angels ... All of this was bringing their world to an end.
No matter what she did, the world would end ... In a last attempt to keep at least some of her creations alive, she decided to send people from her world into a universe without magic, a world known as "Earth". However, she did not think that by doing this, the gods of other worlds would be interested in the planet earth, many of them sending dangerous beings.
Knowing this, Sora turned the most trusted people into "guardians of humanity". It is up to these "guardians" to protect the world and people. Will they be able to do that?
