Saintly heroine? None. NTR? None. Character development? Maybe. In short, you might not get what you want, but you won't get what you don't want, either. The apocalypse arrives, plunging the whole world into chaos. Besides zombies, there are parasitic monsters. Is it a natural disaster or a man-made one? This is a diary of the apocalypse, left behind by a soldier from that era. It will reveal how the apocalypse began and ended. If you really found yourself in a situation like this, what would you do? This work has no romance, no harem, no detailed character development, and no System. If I notice any contradictions, I'll make sure to revise them. Just like its title suggests, the story is written mostly from the protagonist's personal perspective, so there won't be much dialogue or detailed plot.
