At a certain minute and a certain second on a certain day of a certain year, a certain month: Something similar to an alien spacecraft suddenly appeared over many cities - at least that's what it was here at that time.
This undoubtedly attracted great attention. Seasoned experts rushed to cities where floating objects existed, but after a year, they still could not find out what it was.
People gradually got used to it and no longer paid too much attention to it, just treating it as a prank played by some people.
Even news reports about the floating object have gradually declined.
Disasters often occur when humans are at their most lax: a hole opens in the floating object, and many strange humanoid shapes, neither human nor ghosts, jump out of it. They will actively attack humans.
This is where the apocalypse begins.
Human beings live in dire straits because they are unable to do substantial harm to those weird humanoids.
Perhaps human beings should not be extinct, and someone has awakened their supernatural powers. Since then, human beings have been divided into two categories: aliens and non-alien. The aliens bear the responsibility of protecting the non-alien. This is the only way for all mankind to continue.
"We are the last line of defense for all mankind."
It looks cool, but in fact, although it is a bit off-putting when it comes to criticism, it is steady and hard to attack.
