Defense organization in a post-apocalyptic world
Once, the world was covered by an unknown calamity called the "Finality." Civilization crumbled, nations vanished, and even the ecosystem was drastically transformed. Humanity was pushed to the brink of extinction.
Even so, the survivors did not give up. Over long years, they reconstructed the lost civilization and built new nations and cities.
—And now.
The world has once again become a place where people can live.
However, the scars left by the Finality have not vanished.
Monstrous lifeforms born from the influence of the Finality—Devouring Shadows (Abyss). These monsters, which feed on negative emotions such as fear, hatred, and despair, still appear in various parts of the world.
The Dawn Institute is the largest human defense organization countering them. The ultimate combat force standing at its peak is the elite few of Special Unit Zero.
Today, the battle of those living through the apocalypse begins once more.
A past unknown calamity called the "Finality" once covered the world, causing the collapse of civilization, ecosystems, and social infrastructure. Humanity was pushed to the brink of extinction, but survivors spent long years reconstructing civilization.
An unknown calamity that erodes the world, eventually returning everything to nothingness. It occurred once in the past, nearly destroying the world. While it has currently subsided, its influence remains in various regions.
The peaceful world before the Finality arrived. Most of its civilization, technology, and culture have been lost, with only fragments remaining as ruins or records.
The current world. Humanity has reconstructed the once-collapsed civilization, forming nations and cities. However, it is not as prosperous as the Old World, and scars of the Finality remain everywhere.
The largest human defense organization aimed at countering the Finality. It possesses various departments and units, including the "Special Forces" as the highest combat power.
The highest combat power of the Dawn Institute and the strongest elite minority unit.
The world's largest giant fortress city. It serves as the headquarters for the Dawn Institute and humanity's ultimate defense stronghold, where members from all over the world gather.
Unknown monstrous lifeforms generated by the influence of the Finality. They are born from the condensation and manifestation of negative emotions from humans and living creatures, which they feed upon. They cannot be defeated by normal attacks and only vanish when the core inside their body is destroyed. Their appearance and abilities vary by individual, and some possess intelligence.
