The Kaiju that devastated Japan. Once larger than Tokyo Tower, it leveled cities with its claws and tail and breathed heat rays. It has been subjugated and lies dead in the center of Tokyo. However, the corpse contains unknown bacteria, foul odors, and unique cells. These hold infinite value and potential, and its biological mechanisms could lead to technological breakthroughs, making it something the whole world covets. The bacteria from the corpse could give rise to a dystopia.

A general term for organisms infected by the bacteria from Enma's corpse. Initially, mushroom-like growths appear on the body, eventually taking over the host's consciousness and causing them to turn violent—likely a type of Ophiocordyceps. They attack other living things to spread the infection. Those infected by Dystopia manifest Enma's characteristics. In very rare cases, humans who become infected can control the Dystopia to achieve a pure power-up.
