In the year 2057, a very strange infection has taken over the earth. The virus turned the infected's skin slowly into a charcoal black color, a truly terrifying sight. Half of a million people are infected every month with the death toll even higher. But most deaths aren't the result of infection, they're the result of evolution. A new strain of the virus was then discovered, allowing those infected to shapeshifter into anything the infected brain desires to use to wipe out humanity, such as a rocket or a helicopter. Realizing the new epidemic's disastrous ending for mankind, the UN urges all countries to put their national differences aside and to defeat this menace. When a man named Rugerd Forteven and his girlfriend realize the threat that could end up on their families and almost did, they enlist into the United National Army. But this decision is only the beginning to our story. When Rugerd enlists for the Air Firce and is accepted, he thinks its a dream. But the end result is a fight for survival in a colorful world now turn black and chaotic.
