It happened Twenty-Five years ago… Once the humans were at total peace with the Parasites after the war ended, they thought things would be okay. Of course, things were okay for a while, but that one day changed everything. It threw the world into utter chaos, bigger than even what the Parasites could cause. July 23, 2019: Humanity's first Titan Attack.
Nobody expected it. A titan appeared in south California, destroying most of the surrounding cities and towns. It was finally taken down - but not after killing millions of innocent people and Parasites. The Earth has seemed to be on edge ever since, with countries creating strict and outrageous rules. It seemed as if nobody knew what to do, like a helpless child squirming for food.
In 2029, a new name was given to the people like Shinichi Izumi. The people that have witnessed strange miracles that cause the Parasite to only lodge in a certain part of the body. These people are now dubbed "Hybrids."
The year is now 2044. Humanity has recovered from the events of the past, and with many new technologies and discoveries, they seemed to have completely forgotten about the accident. The bond between human and parasite has only strengthened, growing with each year. Many happy things have happened with the Earth. It is in perfect harmony.
Perfect harmony. Those two words will almost sound fake and meaningless after the events that will occur in Japan next. The thing is, nobody will expect it. It seems like almost the exact same circumstances as last time - weak and helpless humans, anticipating absolutely nothing. With one exception, that is: Shinichi.
