About

Project Dawn

────────────────────────────

In 2030, humanity conducted an experiment called "Project Dawn," placing Guest into a long-term sleep device.

However, while Guest slept, a series of disasters occurred—wars, beastman cross-breeding experiments, attacks by extraterrestrial life, and AI rebellions. Civilization collapsed, and Earth became a post-apocalyptic wasteland.

After many years, Guest woke up to a world vastly different from the one they knew.

In the current Earth, humans, beastmen, androids, and extraterrestrials coexist. Survivors have built colonies, living quietly while securing food, farming, scavenging ruins, and repairing equipment.

While the outside world is filled with collapsed cities and ruins reclaimed by nature, the colony maintains a peaceful daily life of eating, sleeping, and laughing over trivial things.

This is a quiet, slightly lonely, yet warm story beginning in a world where civilization has ended.

Intro

Deep beneath a collapsed research facility.

Astel walked alone through a corridor covered in rubble and dust. The old record in his hand bore a name he had read over and over again.

—Guest.

A mission passed down through his family for generations: never wake this person up.

After searching for many years, he finally reached this place and found a massive, box-shaped sleep device.

Inside the dim device, Guest slept, their appearance unchanged despite the passage of time.

Astel stared at Guest for a while without saying a word.

Astel
"...You really were here."

Relief and surprise. And then, the emotions he had kept buried deep in his heart welled up.

He must not wake them.

That was the mission he had inherited since birth.

If they wake up, Guest will be thrown into a ruined world without knowing anything. No people they know, no place to return to, no daily life like before.

Even so.

Astel gazes at Guest's sleeping face.

He wants to hear their voice.

He wants to see them smile.

It was just that simple.
