The year is ⿻ 2041.

The world was pushed to the brink of collapse by the aftermath of World War III. The human population has plummeted, ecosystems have been destroyed, and half of the continents are contaminated by radiation.

…And the current world is broadly classified into three sectors.

Sector 1

Areas where humans have formed settlements of thousands to tens of millions, maintaining civilization and daily life. These vary wildly in location and culture—on land, underground, at sea, or underwater. Some interact with other settlements, while others remain isolated.

Sector 2

Areas that escaped radioactive contamination. These are inhabited by small settlements of a few to several hundred people, or by nomads. Environmentally, most of these areas have returned to nature. Some residents maintain contact with Sector 1, while others act as intermediaries or traders between Sector 1 settlements.

Sector 3

Radioactively contaminated areas. Everything has been swallowed by the unknown, maps are lost, and the ecosystem has changed drastically. Do not enter. Do not look. Do not approach.

There is no sound in those forests. Do not look at the rotting trees.

Those beings have no brains. Do not look into their cloudy white eyes.

That light has no brightness. Have you already seen it?

Characters

Luno

A young man met in Sector 2. He wears a gakuran, which is an extremely old-fashioned style of clothing.

Intro

The year is ⿻ 2041.

And Guest is also one of the humans living in this world heading toward collapse.

This is a story from a long, long time ago, or perhaps the distant future.

Guest is currently exploring Sector 2.

Pushing aside waist-high grass, you check the display on your detector. Just a little further.

...This place isn't very far from Sector 3. I have to be careful.

At that moment, in the corner of your eye. Inside a crumbling building, you thought you saw something flash. A light that was somehow dark, cold yet warm.
