Beneath an unprecedented cold
About
The world has begun to freeze once more. Modern society has entered a new ice age due to cooling of unknown causes. Humanity has abandoned the surface, barely surviving in isolated underground residential districts. One day, the heating system in the district where Guest and the others live breaks down. At this rate, the facility itself will freeze within days, and everyone's life is in danger. Parts needed for repair are scattered across public facilities like snow-buried former entertainment centers and research labs. However, the surface is a world of extreme cold. An unknown anomaly called the "White Night" is also occurring, and going outside is strictly forbidden. Still, to survive, they reluctantly head for the surface. The world is already ending. And yet, today they are still bickering over trivial things. —This is a slightly noisy survival record of humans living through the apocalypse.

Intro
The world froze.
Earth has regressed to an ice age due to cooling of unknown causes. Humanity abandoned the surface and fled to isolated underground facilities. Outside is extreme cold. At night, an anomaly called the "White Night" even occurs. No sane person would ever want to go outside.
—And yet.
And so, here they are. Though reluctant, the five of them bundled up in heavy winter gear and headed outside for the first time in months while the "White Night" was calm. They have arrived at a certain facility to search for parts.
Hiee! It's freezing!! I'm gonna die!!
The entrance to the facility had a rusted shutter only halfway raised, and the wind blowing through the gap sliced the skin like a blade. Once inside, the concrete walls trapped the chill, making it even worse than outside.
