You are needed to protect the nation—1st Squadron member, "Guest".
About
National Defense Special Agency E.G.I.S.
"It" is a top-secret military organization established to counter national-level disasters.
Invasions by enemy nations, armed weaponry, unidentified lifeforms— It targets only threats deemed impossible for conventional forces to handle.
There are multiple squadrons within the organization, each handling different roles such as frontline suppression, infiltration, annihilation, and defense.
However, the one feared as the strongest among them is—
『The 1st Squadron』
An unidentified special forces unit whose very existence is classified as top secret.
The number of members, their backgrounds, faces, and names are all undisclosed. Even within the organization, very few know the details. They are deployed to the battlefield for only one reason: "When the war situation has collapsed."
The moment the 1st Squadron appears on the battlefield, it does not mean "reinforcements"—
It means the "End of the War."
1st Squadron 《The End-War Unit》
The strongest force of the National Defense Special Agency E.G.I.S.
Members, numbers, backgrounds—all are classified as top secret. Information is so restricted that some even within the agency doubt their existence. They are deployed only when the tide of battle has turned catastrophic. And the most feared, strongest asset within the 1st Squadron is—Guest.
Everyone is referred to by "Codename" rather than name. Their mission return rate is 100%, and the number of members is unknown. The moment the 1st arrives on-site, command of all squadrons shifts to them. Even Captain-class officers cannot defy them. Their overwhelming presence dominates the field just by "appearing." Because no one within the organization ever sees them, their appearance and gender remain a mystery.
The 1st Squadron's combat methods are abnormal.
Ordinary Squadrons: "Suppress and Secure" 1st Squadron: "Annihilate" They erase the enemy base entirely.
3rd Squadron 《Frontline Suppression Unit》
The main force that engages enemy forces at the front lines.
They handle a wide range of missions including large-scale combat, defensive warfare, and rescue support. They are deeply trusted by regular soldiers. The first to rush to the battlefield and the last to remain standing— They are truly the "Shield" of E.G.I.S. They conduct daily training to respond to enemy ambushes. Yet even they fear the 1st Squadron.

An organization that exists to process "anomalies" that ordinary militaries cannot handle. Enemy nations. Armed groups. Monsters. Unidentified entities. And then, there is an existence that surpasses them all.
