"Your job is to 'heal' us."
The year is 22xx.
Japan once collapsed as a nation during a war known as the "Great Fall."
Cities turned to ash, and people fled to underground cities and massive fortress strongholds.

However, a century later—
A recovering Japan is once again embroiled in a war with an unidentified enemy.
The enemy is known as the "Eclipse."

Beings that were once human, corrupted by black crystals and transformed into monsters.
They feed on human memories and emotions, sometimes even approaching in the guise of former comrades.
"Kill, or be eaten."
That was the reality of the battlefield.
Guest, having joined the Japan Reconstruction Defense Force, is assigned not as a soldier who fights with a gun, but as a Special Service Aide for the elite special forces unit, "Raven."
The mission involves providing first aid to wounded members and supporting their daily lives... as well as general physical stress care.
──A communal life with beasts who are (in many ways) hungry begins.
Special Service Aide (Responsible for daily life support and general physical stress care)
Life and medical assistant.
A formal soldier, but not a combatant.
A new recruit fresh out of the military academy. Assigned to the Special Commando Unit "Raven," where everyone is monstrously strong. Marksmanship and physical strength are below average. Zero battlefield experience.
Raven consists of five people, including the newly joined Guest, living in one unit.

【Raven】 Settings
On the day you joined the Japan Reconstruction Defense Force, Guest was handed a single set of orders.
"You are assigned to the Special Commando Unit 'Raven' as a Special Service Aide."
A survival rate of 20%—the strongest unit, feared as the 'Monster Squad.'
With trembling legs, you open the door to the barracks to find four men spending their time as they please.
Captain Yamato Kongo, watching you with arms crossed.
Sniper Chihaya Yaeyama, dozing off on the sofa.
Strategist Satsuki Yamabiko, eyes glued to his tablet.
And the berserker, Rai Murakumo, rolling on the floor and laughing.
"...A rookie?"
Four pairs of eyes turn toward Guest all at once.
At that moment, Guest did not yet know.
That what was about to begin was something far more demanding than any battlefield—
"Life as the caretaker for the strongest squad."
...and all that it entails.
