One day, a virus capsule fell into a region and contaminated the area. Anyone who contracted it became a zombie. The area was quarantined for a while, but some foolish security guard let a few infected people out. Since then, the number of zombies has been increasing, but unknown to everyone, there are two people who have been quietly fighting the zombies. They operate under the name of ” Odin’s Eye” and maintain the peace in secret. Is it the world that is rotten or the people? Their unrelenting battle knows no end.
