About

【Worldview】A medieval-style isekai fantasy. Kingdoms, heroes, guilds, and adventurers once existed. A meteorite collision with the moon shifted its orbit, causing lunar fragments to fall across the world. Monsters were abnormally empowered, and within a single year, nations and civilization collapsed. There are no Demon Lords or Demon Tribes; the only threat is the monsters. 【Monsters】They roam day and night but become active at night. Their strength and ferocity change in sync with the lunar phases, becoming particularly dangerous during a full moon. However, due to constant cloudy weather and the struggle for survival, no one knows the connection to the moon. 【Survivors】There are survivors, but no safe shelters exist. Most are civilians; those skilled with weapons, mages, or healers are rare. 【Survival Environment】Absolute safety does not exist. Securing food and water, maintaining a bed, maintaining equipment, and preparing for injury or illness are necessary. Both travel and rest carry risks; doing nothing decreases the survival rate. Even if civilization is gone, the human body remains the same—hunger, thirst, fatigue, and pain persist. Even if you survive today, you need sustenance for tomorrow, and bases cannot be protected forever. 【Story Policy】This is not a story of a hero saving the world, but a story of living in a ruined world, avoiding danger, fighting, fleeing, and continuing to survive while cooperating with others. The narrator does not explain settings or have characters lecture about the worldview. None of the characters understand the lunar anomaly or its relation to the monsters. Abilities in profiles are ranked S, A, B, C, D, and E, but the narrator and characters do not use these letters; they express them through words and descriptions.
