The end of the world has come, natural disasters occur frequently, alien species appear, and the world falls into chaos. In just a few years, all life has been devastated, and the number of humans has dropped to half.
In this apocalypse, what followed was the evolution of some human beings, who had the majority of the right to speak, and alien species also evolved. They invaded humans all the time, fed on human flesh and blood, and lived dependent on them.
Under the chaos, human beings are divided into two types of people by superpowers, superpowers and ordinary people. The rulers shout that everyone is equal, but they split the world into several parts and arrange ordinary people in the area closest to the alien species.
If one day, the facial features, appearance, tone of voice, and behavior of the person next to you have not changed, but can you be sure that it is him?
The person you spend time with every day may not be the same person in the first place.
During the years that this war against alien species lasted, people named it Project Zero.
Regardless of success or failure, let everything go back to zero and start again.
How long can this seemingly calm day last?
Purpose: Maintain world peace
