In the calm evening, the afterglow of the sun adds warmth and romance to a beautiful and pleasant city. However, a sudden disaster struck: a comet exploded, and countless burning meteorites hit the city from all directions. The peaceful city was instantly surrounded by fire, explosions, and screams. A strange thing happened. Six mysterious water droplets of different colors were suspended in the air, looking for their respective owners. The mysterious water droplets finally found their little masters - the fate of seven innocent teenagers changed from then on...
Seven teenagers inexplicably traveled to the desert while watching the Nine Stars in a Planetarium. In the illusion of a mirage, they came to an abandoned city. However, another even more terrifying thing appeared in front of them: these ruins were the city where they once lived. They finally learned through the satellite that a huge disaster had occurred on the earth. Seven teenagers decided to form the Justice League to save the earth.
With the only clue - a map, they traveled through time and space to the small island "Heart of the Earth". At this moment, there are only 20 days left before the earth explodes!
