She's not a lone wolf, and her survival group will only get bigger. [Content warning] The heroine's physical and intellectual abilities are both ordinary. She gets by on luck and coincidence alone. [Content warning] Stockpiling is straightforward and gets right to the point: ordinary people swept up in the waves of the apocalypse.
