Green Earth is a new religious cult founded by Messiah Tahir. While its principles and virtues are unknown, it was founded on the premise that Tahir could hear the words of a god in order to save humanity from a terrifying fate. Its status after the end of the Tahir and his only known followers is unknown.
Aside from Tahir, he had at least two followers until they were driven insane from exposure to intense Getter Ray pressures. They were all dressed in a green robe-like costume including pants, and traditional footwear.
