After a crisis on Earth, humanity, or should I say the entire world, changed after an incident.

In three decades, the world drastically changed in terms of technology, drones, world order, and many more. It was accomplished by only one person named Takahashi Tsubasa, with the help of his advanced drone technology. He was also awarded by the world government, the UN, for his creations.

According to the history that was told to children, across the world in different locations, portals started appearing out of nowhere, and from these portals, a monster emerged. It was described as having a big body like a lion without fur and just bare skin, with only one eye on its forehead. But what was more terrifying was its sharp fangs, which stuck out like vampire fangs. The monster, with its sharp fangs, could easily transform anyone into it by biting them.

The incident occurred all over the world. After that, a barrier appeared out of nowhere in each country. There was also an instance where whole countries disappeared through portals, which shook the entire world and caused a lot of confusion when they were teleported near different countries to various locations among different people.

There were also stories of how one person among the crowd at each portal location was there to fight back against each monster, and the monsters were then sent back after their defeat through the portals they came from, with the help of people that nobody remembers. Each individual from a different location entered the portals, and they never returned; the portals were never seen again, and the mystery of the people who helped them remained a secret.

Then the era of drones came along, led by the scientist Takahashi Tsubasa, which helped to maintain the environment in particular areas that were in great need because of the teleportation incident. This was nearly accomplished by drones that could withstand for a few days (exactly 2-3 days) without disturbance and it was later then that it was perfected. (which withstand more than a year)

After a year, people started to adapt to the new laws, environment, and technology, along with a lot of new changes that happened in the past three decades.

Crimes also increased, and big drones were used to find the locations of criminals. Robots were deployed to capture criminals, but this only lasted for two decades. Criminals only grew because of that, but the robots and drones were also further enhanced to capture criminals.

A few years back (exactly 3-4 years from the present time), the crime rate still decreased due to an unknown vigilante. It is still not known who he is, but he has been a great help to the people. Last year, he announced his name as Nitro after helping people for the last three years; he revealed himself in broad daylight as well.

Takahashi Tsubasa has a son and a daughter; actually, he had three children, but after his wife went missing, and before she went missing, one child (the younger one) got lost at a carnival after she went to search for the younger one sibling but instead goes missing.

His son kouzuki Tsubasa is genius like his father but there is also a secret he is keeping from his father.
