Oxer, they are a terrible species
Sometimes they blend in with the crowd and no one can spot them
They harm mankind
Some righteous humans accidentally became armored warriors
At this point, they are responsible for fighting Oxer and protecting the Earth
Let's see where the Armored Warriors and Oxer go, and which side will win the final victory...
PS: I suddenly wanted to read fanfics about armored warriors, but found that there weren't many, so I planned to write one myself. If readers find it interesting, please recommend it to your friends. The author will update it every Sunday. Thank you for your cooperation!
