Almost all the human race that had led an ordinary life up until that moment, were not able to avoid the World War and the collision of asteroid (2063DX) with the moon because they could not secure an adequate period of time to anticipate and prepare against them, while the national organizations including the government, already engaged deeply in the war of the insane, and finally collapsed by themselves.
With the national and social systems being disrupted and the economic base and industries being ruined, the exposure to the radiation and the SOD created a variety of malformed organisms that survived as the Sourocky Mutants and became the enemies or avoided the eyes of the human race that also survived. Very few among those who were exposed to the SOD, however, showed a far better physical ability or cognitional performance. Among them, some people who had adapted themselves to their own changes showed off or began to properly use such abilities or performance. Otherwise, others concealed their ability or abused it. A lot of researchers noted such a phenomenon and named it SOD Syndrome.
The theories that underlay the Syndrome indicated that it was a case that took place with a very small probability when one was exposed to radiation again, after he or she was exposed to radiation, while its probability was far lower than the probability that the same subject became a Sourocky Mutant or just died.
