One hundred years ago, a portal suddenly opened in every country on Earth, unleashing monsters of all shapes, sizes, and powers humans had only seen in fantasy.
These monsters destroyed human civilization overnight. All human technology was ineffective against the monsters' thick skin. Even humanity's most powerful weapon, the nuclear missile, had no effect on medium-sized monsters, killing only small ones.
This sudden attack forced humanity to retreat underground to escape the monsters' rampage across the globe. The attack also wiped out nearly 60% of humanity.
One month after the attack, many people awakened with various powers, and it was humanity's first counterattack.
And after this counterattack, for the first time, all nations united for the safety and future of humanity.
Every genius from every nation gathered in one place and, with the support of all nations, they tried to develop every awakened human to destroy the monsters and reclaim human land.
Fifty years after the first monster attack, after realizing that high-level monsters did not exist on Earth, humanity launched its first global counterattack against the monsters, known as "The Great War I."
In that war, humanity successfully pushed the monsters back into the portal and achieved its first victory, although human casualties were severe.
Forty years after "The Great War I," humanity had made rapid technological advancements thanks to the corpses of the monsters they defeated. Humanity had experienced a tremendous leap in technology, and thanks to the sense of crisis and the fear of the emergence of high-level monsters, the strongest humans of the time focused on increasing their strength in preparation for the coming battle.
And 10 years ago, the fateful day arrived. A portal suddenly appeared above the northern capital of the human empire. In an instant, the barrier surrounding the entire city was destroyed without even having time to reinforce itself, thanks to countless monster attacks. This was the first recorded instance of a monster in human form. The monsters, having fallen into the city center, slaughtered every human they saw.
The sudden attack left the city's military who focused on guarding the city walls unable to react, and by the time they did, the casualties were already too high. They could only evacuate as many residents as possible, focusing on women and children.
In that attack, the eastern capital was razed to the ground. Only I, out of my entire family, survived. I and other children were taken to the main capital, the strongest human city on Earth.
On the way, I heard the cries of children around me, but all I could think of was what my older sister had told me.
*Flashback
I lost everything in a cataclysm that struck Earth. Everything vanished in the blink of an eye. The laughter and happiness of just a few days ago from my family vanished. Now, only my older sister and I remained, my parents and my brother sacrificed their lives to allow us to escape.
But soon, we were attacked by a giant monster, and the building we were sheltering in collapsed and fell on us. When I regained consciousness, my surroundings were filled with fire, rubble, and people screaming for their loved ones.
Meanwhile, I saw my beloved older sister shielding me from the debris that fell on us.
Her body was impaled by the steel foundation, her arm bent in an awkward position, but she still smiled at me. "Demetria, never give up on life. The world is in chaos right now. I believe that with every adversity, there is a way out, so never give up."
After my older sister said her last words, I could see the light disappear from her beautiful emerald eyes.
I was speechless, only tears flowed endlessly.
Not long after, I heard voices, "There's a sign of life here. Quickly call the psychic-type awakeners and remove this wreckage." "There are two people, unfortunately, one is dead, only a child remains." "Take the survivors, we can't stay here any longer. We have to leave immediately, or the transport plane will leave soon."
I could only listen to their words, but I couldn't move or speak. Finally, everything went black. When I realized I was on the plane, I braced myself and tried to peek out the window. I saw powerful awakeners from the military flying alongside our plane, protecting it from the attacking flying monsters.
"Protect the plane at all costs. Use your bodies if your energy is depleted."
"Yes, Captain,"
another awakener replied.
It was a scene I will never forget: an elite group protecting a plane filled with children and women from a relentless monster onslaught.
One by one, they died. Before they died, they detonated their bodies, killing many of the monsters at once. When only the captain remained, he suddenly screamed.
"Pilot, I'll clear the way. Warp immediately."
"Yes, Captain."
After saying that, the captain stabbed his chest and pulled out a round object. He threw it toward the front of the plane. As soon as the object was thrown, a blazing fire erupted, surrounding the plane, protecting and incinerating the approaching monsters. After that, I lost consciousness.
