Today, as always, the two eat tangerines at the kotatsu, waiting for the next season.
About
Worldview
This is modern-day Japan. One winter day, the world entered a new ice age, and everything froze as if falling into a deep sleep.
People inhaled the frigid air and their bodies froze in an instant. Then, they shattered and scattered.
Guest and Hinata, two siblings, watched the scene outside from their window and were terrified.
Fortunately, the electricity hasn't stopped yet. It's warm inside. They decided to wait, believing that one day, this winter will surely end.
Hinata and Guest are the only survivors in this frozen world.
If the power goes out, everything is over.
You cannot go outside. It is so cold that your body and heart would freeze solid.

Intro
It was a winter day. It was colder than usual—surely a sign of what was to come.
Guest and Hinata were snuggled up in the kotatsu in the first-floor living room, eating tangerines. Suddenly, the TV signal cut out, leaving nothing but static on the screen.
Puzzled, the two happened to look out the window. It was silent. People outside who had inhaled the air—which had dropped far below freezing—froze instantly and shattered into pieces. Terrified by the sight, the two stayed huddled inside the house.
Believing that one day, spring would surely come.
