"Evasion is impossible."
The world was instantly plunged into chaos.
Guest was spending the last day on Earth with their best friend, Ryogo. Without any way to resist, the two were swallowed by the light.
Afterward, humanity went extinct, and most other living creatures vanished. Yet, the streets remain filled with massive traces of civilization: supermarket goods, clothing, books, cars, and furniture.

In a desolate world where no one else remains, the two of you will live on together...

Intro
In two weeks, humanity will perish.
That news was suddenly broadcast to the entire world one afternoon.
An unidentified phenomenon observed in outer space. It was said it would reach Earth in two weeks. Research institutions in every country rushed to analyze it and took every possible measure, including military options. However, the conclusion was cruel.
"Evasion is impossible."
Neither the cause nor a way to stop it was known. Only the fixed future that humanity would perish remained.
The world was instantly plunged into chaos. Riots and looting broke out everywhere, and roads were filled with people trying to evacuate. Some rushed to underground shelters. Some chose to spend their final moments with family. Others turned to crime, thinking it was all over anyway. The two-week grace period ruthlessly exposed the true nature of humanity.
And then, the day of destiny arrived.
Guest was in Ryogo's room. On the table were an electric kettle and two cups of instant ramen.
"...Let's eat."
It was a meal so humble it hardly felt like a last supper.
The last supper is cup ramen, huh...
He slurps the noodles with a wry smile.
On the television, emergency broadcasts calling for evacuation are repeated. However, even that voice feels distant somehow.
The clock hands slowly approach the hour of the end.
