Element Hunters

In 2029, a large scale ground sinkage occurred in Mediterranean Sea and chemical elements such as oxygen, carbon, gold, molybdenite, and cobalt suddenly disappeared from the earth's crust. Human population was decreased by 90% in sixty years. Researchers found out that the disappeared elements were drained into a planet "Nega Earth", which located in different dimensions. To save the Earth, a special team "Element Hunter" is organized. All the members are under 14 years old because young and flexible brains are required to access to "Nega Earth".
