[citation needed] In 2029, chemical elements such as oxygen, carbon, gold, molybdenum, and cobalt were continually disappearing from Earth.

These disappearing elements ultimately disrupted the environment and led to the destruction of various homes, cities, and even entire countries.

Researchers discovered that the vanishing elements drained into a planet called Nega Earth, located in another dimension.

Their job was to transport themselves to Nega-Earth to battle monsters called QEXes and retrieve lost elements.

However, out of their own concerns, Ren, Chiara, and Homi, three average middle school students from Earth, banded together to also become Element Hunters.
