Introduction
The word world itself was something gray nowadays. There weren't many signs of life in sight. Decades ago, humans were obliged to be vaccinated to increase their immunity to survive the worsening pollution on earth.
But like a bolt of lightning in broad daylight, the side effects of the vaccines became a nightmare for this world. The minority of people who got vaccinated turned to be very aggressive, incredibly strong, and had permanent animal instincts in their behavior. What's wrong with them?
Their bodies resisted the change but they just couldn't fight it. It couldn't be removed to the point where their bodies were just like being taken over and replaced by only ferocity, just like a hungry beast.
Yes, they literally turned into a beast who ended every human being they met.
On the other hand, most of the other humans who got vaccinated fortunately didn't feel that insane side effects. But still, there's another issue; apparently, their bodies reacted to the vaccines differently.
Some reacted by becoming very weak, and some turned very strong. But these two kinds of humans were at least still being themselves and didn't transform into a bloodthirsty beast.
Because of this issue, the leader of every country around the world agreed to classify humans based on the side effects of the vaccines. There were four groups in this classification; red, yellow, green, and blue.
Red, for those with very bad side effects which made them physically extremely weak, vulnerable to be infected (if these people got bitten by beast), and not strong enough to the air pollution.
Yellow, for those who were strong enough to survive. They're also immune to the bad pollution but there's still a possibility to be infected if got bitten by a beast though it was a rare case.
Green, for those who were physically strong, they were agile and fast. Their strength was slightly above the average human in general. They're also immune to the beast bite infection and air pollution.
Yellow and green were the majority. Most of the people who got vaccinated belonged to these two groups.
While the last was the Blue group. This group was for those who became "superhuman" because of the vaccines. Even though their numbers were small, their existence brought hope as it was expected to positively impact society.
This Blue group was remarkably strong, fast, agile, and of course, they were also immune to beast-bite infection and air pollution. Their resilience was incredible and their bodies also had an impressive ability to heal themselves. There was just one weakness: Their strength would decrease as it darkened. They would totally weaken at night. Their power would be drained if they happened to be involved in a fight.
But one exception in this blue group whose strength was not affected by day or night. It's the sapphire blue one. It was the strongest group among all, the special one. But this kind of group was extremely rarely found.
Governments made the blue group as "soldiers" for the country to protect those who were weak because the beasts were increasingly rampant in chasing humans, slaughtering the weak, making them easy prey.
With the military training, the blue group sharpened their combat and fighting skills, strengthened their self-defense, and became the guards for each area that had been divided into several camps.
Now, everyone had a group badge around their necks to make them easier to be recognized. Whether they belonged to the Redties, Yellowties, Greenties, or Blueties group.
As time went by, the Redties were becoming less visible because they were the weakest not only for the beast bite but also because of the air pollution poisoning, causing the human population to decrease day by day drastically.
With that being said, there's one question that came to every human mind; what exactly could the Blueties do to prevent human extinction from this planet?
Let's find out.
