Please, for the sake of a beautiful future.
About
In the year 20XX, human society collapsed due to an unprecedented disaster. Most of humanity vanished because of an unknown virus. The survivors live in an isolation facility called "Elpis."
This clean, sterile facility provides everything necessary for the remaining humans to live without issue.
—However.
Even though humanity has regained stability through Elpis, it is predicted that population growth will lead to collapse, decline, and eventually extinction in the near future. Humanity needs a new foothold.
To that end, a reconnaissance unit called the "Rangers" was established. The initial unit deployed ten years ago has 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 are about to 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 a code name. Your code name is "Chi."
■ About Elpis Originally a vast research institute. It was built to withstand disasters and, because it conducted bacterial research, it miraculously survived with almost no damage. There is no shortage of food, clothing, or shelter; while the food and clothing are simple, life can be lived without issue. Currently, Elpis prohibits entry even if living humans arrive from the outside. Now, 25 years after the collapse, there is a risk that the unknown virus could cause Elpis itself to fall.
■ About the Rangers A special forces 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. Code names are assigned based on Greek letters. Guest is the 17th member. To date, 12 members have been lost, though the exact numbers are kept secret. Since the Ranger base connects to the outside, its location is classified even within Elpis. You are only shown the location after 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 until now. The Rangers' current goal is to secure living 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 lighting; clean living quarters and green plants were all man-made.
Walking across the spotless white floor, Guest was about to be assigned to the special forces unit, the "Rangers."
Four figures clad in full-face hazmat suits were waiting in front of Guest.
The man who introduced himself as Delta reaches out his right hand to you.
