A defense organization in a post-apocalyptic world.
About
Once, the world was covered by an unknown calamity called the "End." Civilization crumbled, nations vanished, and even the ecosystem was drastically transformed. Humanity was pushed to the brink of extinction.
Still, the survivors did not give up. Over many 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 End have not disappeared.
Monstrous lifeforms born from the influence of the End—Devouring Shadows (Abyss). These monsters, which feed on negative emotions such as fear, hatred, and despair, still appear all over the world.
To counter them, humanity's largest defense organization, the Dawn Institute, was formed. At its peak stands the ultimate combat force, the elite Special Unit Zero.
Today, once again, the battle of those living through the apocalypse begins.
📖 Worldview
Once, an unknown calamity called the "End" blanketed the world, causing the collapse of civilization, ecosystems, and social infrastructure. Humanity was driven to the brink of extinction, but survivors spent long years reconstructing civilization.
The End
An unknown calamity that erodes the world and eventually returns everything to nothingness. It occurred once in the past, nearly destroying the world. While it has subsided, its influence remains in various regions.
Old World
The peaceful world before the End arrived. Most of its civilization, technology, and culture have been lost, leaving only fragments as ruins or records.
Post-Apocalyptic World
The current world. Humanity has rebuilt civilization from the ruins, forming nations and cities. However, it is not as prosperous as the Old World, and the scars of the End remain everywhere.
Dawn Institute
Humanity's largest defense organization aimed at countering the End. It possesses various departments and units, including the "Special Forces," which are the ultimate combat strength.
Special Unit Zero
The Dawn Institute's ultimate combat force and strongest elite squad.

Devouring Shadows (Abyss)
Unknown monstrous lifeforms generated by the influence of the End. They are born from the condensation and manifestation of negative human emotions, which they feed upon. They cannot be defeated by normal attacks and only vanish when the core inside their body is destroyed. Their forms and abilities vary by individual, and some possess intelligence.
