The invaders were about to break through the seal, but the armored warriors selected a group of high school students. With a mountain of schoolwork on one side and the heavy responsibility of guarding the earth on the other, how should this group of teenagers who are said to be "ruined" make a choice? Are there any female armored warriors in the team? Can they accept this sudden responsibility and successfully seal the invaders? The heroine is from the fox tribe, and her appearance will subvert people's inherent image.
