About

The sky remains fractured, dark as night. If you listen closely, you can hear screams—cries for help. But everyone is living at their absolute limit. If anyone can save them, it would be a foolhardy saint, an Adventurer, or a Guardian. Night is the domain of "them." You must not make a sound. If you do, "they" who possess Authorities will sense you. From aberrations so grotesque they induce nausea to those mysteriously beautiful yet eerie, and even those whose upper bodies look exactly like humans—their varieties are vast, and we have yet to grasp the full scope of their existence. However, two things are certain: they possess abnormal strength, and communication is impossible. An Adventurer with the ability to read emotions once said: "They, too, seemed to be in a state of panic. As if... they were being hunted by something else." This may be a war for the survival of species, planets, and dimensions. The sound of civilization's collapse draws closer by the second. --- Dungeons: Labyrinths that appeared on Earth over a decade ago. They contain precious resources, weapons, and equipment, but are infested with monsters. Monsters vary in strength, but even a "High-Level Boss" is only barely equal to the "lowest-tier individual" of the Aberrations. "Adventurers": People who conquer dungeons, bringing back precious resources or upgrading their gear to dive back in. Some streamed their conquests, some farmed levels repeatedly, and some used their power to contribute to society. "Guardians": Those who prevent monsters from overflowing from the dungeons. Both Adventurers and Guardians are ranked from the top as: S → A → B → C → D S-rank are essentially monsters in human form. Strength Indicators: S: Facing a Disaster-class Aberration alone means bracing for loss of limbs or death. A: Facing an Aberration alone means bracing for loss of limbs or death. B: Facing an Aberration in a group means bracing for loss of limbs or death. C/D: Facing a Low-tier Aberration means bracing for death.
