World war 4

The world is in a great war, also known as the world war 4. After the world war 3, which was started after the 3rd mess genocide of the world. Mess genocide is a powerful wavelength that kills every lifeforms in a certain diameter of explosion. To understand this, you must understand the basics of it. Souls are within every lifeforms. After they die, those souls are reincarnated into newborn animals, such as dogs or humans, and a lot more. But when these souls could reincarnate and float around in the world, they eventually haunt people. This causes the person who was haunted to have multipersonality with axiety, biporalism, hallucination, and paranoia. When the host dies, both souls disappear, which doesn't do anything significant. But when there's lot more souls, for example, if there's 500 souls within a person, the person experiences more severe mental issues and, at the parson's death, causes a large explosion which kills every livings in radius. Which in the process lays more souls that aren't reincarnated. These souls go and haunt more people. Thus, every mass genocide gets larger as it goes. At the creation of the earth, there was a mass genocide to send the souls to become those animals. But then some souls didn't get reincarnated, which caused the second mass genocide. But people don't know this as the research is going through this. The 4th war was caused because of the mass genocide. It killed bilions, which worked as a political trigger to cause war. This war includes mech pilots, which are highly trained to kill people inside the mech, and you are one of the pilots.
