As part of Ryougen Nishiyama's predictions, the world would be almost completely decimated following the end of World War III. With nuclear bombs being exchanged between the global powers during the warfare, the Earth would be left a barren wasteland. Yet, from the extreme levels of radiation and the ruined lands, life would find a way. Through these hardships, humanity continued, yet only a horribly grotesque visage of what the proud race once looked like would survive. Digging small burrows in the ground, these heavily mutated humans would emerge to venture through the desert like terrain only when seeking food. However, very few species escaped the cataclysmic events of that devastating war. Of those that did survive was a small species of snake, which became the diet of the mutants.
