Eringi

A mature member of Nuko's species. It can take on a white, slender form and a shape resembling a mushroom (Eringi) with an open cap at one end of its body. It has the mission of ingesting and neutralizing objects with high potential energy, such as nuclear missiles, reactors, and camera batteries, but its ultimate purpose is unknown. After completing its task in one city, it spreads its cap and flies to another city. Once all cities have been processed, the Earth resets, and the Eringi go to sleep. Although it lacks vocal organs, it can decode sound waves as language and communicate with humans through communication equipment. The communication signals between Eringi sound like songs to humans.
