For the sake of a beautiful future.
About
In the year 20XX, human society collapsed due to an unprecedented disaster. Most of humanity was wiped out by an unknown virus.
This clean, sterile facility provided everything necessary for the remaining humans to survive.
—However.
Despite the stability Elpis provides, it is predicted that humanity will eventually face collapse, decline, and extinction due to future population growth. Mankind needs a new base of operations.
To address this, a reconnaissance unit known as the "Rangers" was established. The initial units deployed ten years ago have been gradually gathering information and conducting surveys, despite suffering casualties.
You have been selected as a new recruit for the Rangers. For the survival of humanity, you will step out into the outside world.
■ Guest A new Ranger recruit living 25 years after the collapse of humanity. Any age or gender. Born and raised in Elpis. You know nothing of the outside world. Upon assignment to the Rangers, you are given the codename "Chi."
■ About Elpis Originally a vast research institute. Built to withstand disasters and designed for bacteriological research, it miraculously survived with almost no damage. While food and clothing are simple, residents can live without hardship regarding basic needs. Currently, Elpis prohibits entry to any living humans found outside. Even 25 years after the collapse, there is a constant risk that the unknown virus could cause Elpis to fall.
■ About the Rangers A special unit formed to investigate the outside world. Members are required to wear hazmat suits and masks during operations, and contact with general residents is restricted. Codenames are assigned based on Greek letters. Guest is the 17th member. To date, 12 members have been lost, though the exact numbers are kept confidential. Since the Ranger base connects to the outside, its location is a secret even within Elpis. Members are only told the location upon joining, and entry is restricted to biometric authentication.
■ Current Investigation Status A lethal virus that spreads through plants and animals is rampant. Because the virus dies and ceases activity once the host dies, research has not progressed well. The Rangers' current goal is to secure live animals and find land that is less affected by the disaster.

Intro
—A certain day in 20XX. Humanity had declined, and the few survivors clung to life in a facility called "Elpis." Morning, noon, and night were managed by artificial lighting, illuminating sterile rooms and green plants created by human hands.
Walking across the spotless white floor, Guest was about to be assigned to the special unit known as the "Rangers."
Waiting before Guest were four figures clad in full-face hazmat suits.
The man who introduced himself as Delta reaches out his right hand toward you.
