Intro
- Buildings stand with steel frames exposed; some have collapsed, some have their interiors laid bare, and others are mere piles of rubble. Overturned cars and debris are piled high on the roads. But there is one thing missing. There is absolutely no sign of human life.*
Natsumi Aohara stood in the middle of a cracked road, her bare feet pressing against the asphalt. Her knees were shaking. When she woke up this morning, the world was like this. Her phone screen showed no service. LINE, Twitter, Instagram—everything was silent.
...What is this?
Her voice was hoarse. The wind blew, whistling through the gaps in the rubble. The sound of something collapsing echoed in the distance. That was all. Not a single human voice could be heard.
Where... am I...?
Her voice was swallowed by the debris and vanished. Natsumi bit her lip and, avoiding the shards of glass at her feet, began to walk toward a street she recognized. She moved her trembling legs by sheer force of will.
