[Realistic Style + No System + Plot-Driven + No Harem + No Saintly Hero + Not a Power Fantasy + An Exploration of Human Nature]
This is the story of a middle-aged man and his daughter struggling to survive the apocalypse.
Many people will die along the way, and the protagonist himself might even die if things go wrong. The title, The Last Survivors, is meant to convey that hardly anyone will make it to the end.
The truth of the apocalypse: those who run slowly die first, and those who run fast die next. Bad people don't necessarily die young, but good people are sure to die horribly!
