Year's ago, all living beings started to kill each other with no apparent reason or the reason was ”Killing was fun”. This apathetic thought worried God, so God ordered the Arc Angels to warn the people. But these people ignored the word of God. The Arc Angels were ordered by God to use violence if they refused, So the Arc Angels destroyed the strongest clan, but this doesn't stop the people. With no other choice, The Arc Angels had to use more violence. Pillars made of light descended through skies through the world, then a wave of lights and people who were caught by the waves died, And 2 billion people were killed. This Devastating power caused people to shivers in fear. So the people accepted the contract made by The Arc Angels and peace was formed, there was no murder, no rape, no everything, Just only peace. Fast forward to the future. People started to invent called ”VR Game Cabin”  The VR Game Cabin was simple, It design was a chair like with openable doors once you sit the chair the door will close and a cord will Peirce your neck and you will enter the virtual world. Then many companies started to make fighting games.
