Imaginary world view: With the rapid development of science and technology, people have gradually forgotten the differences between countries. Each ethnic group is divided according to their region. The surface of the earth is divided into 26 regions, coded with 26 letters. Area A is the most luxurious, and area Z is the most impoverished. Each large area contains 10 communities, represented by 10 numbers. Area A has strict security, while area Z has almost no one under its jurisdiction. (This world number is expressed in this way) In order to maintain peace, NY. (The world's highest alliance organization) uniformly recovers and destroys thermal weapons, their data, and related books.

The two extremes seem to have reached a balance, but no one has a clue. Is it just a matter of public security? Until the two evil stars in Zone Z met, breaking the balance...
