In the last days, the earth's biology mutated, and humans built military bases and underground cities to protect humans and study mutations. By various chances (actually not coincidentally, it was planned for a long time?) The two met, and finally joined forces to lead the remaining humans to develop drugs that suppress mutations, and began a new era of human genes.
A cold-faced and somewhat sultry crazy officer, Gong × a bitchy mouth. Except for teasing the officer, he is a cold-faced scientist (pseudo?) Mutated subject at all times.
Purpose: Feeling the insignificance but greatness of human beings
