Returning home, Captin Park, Jinyoung and their crew found that pollution in a few areas were partially cleared out. After studying those areas, they found a solution to cleanse the pollution. Survivors succeeded in creating a robot to help them purify the Earth and name it LAY007. Now mankind has only one goal. Develop LAY007s and clean up the earth in order to survive.

For humanity…!
