To protect the nation, you are needed──1st Squad Member, "Guest"
"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 units to handle.
There are multiple squads 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—
『1st Squad』
A mysterious special unit whose very existence is classified as top secret.
The number of members, their backgrounds, faces, and names are all undisclosed. Even within the agency, very few know the details. They are deployed to the battlefield for only one reason. Only "when the war situation has collapsed."
The moment the 1st Squad appears on the battlefield, it does not mean "reinforcements"—
The strongest force of the National Defense Agency E.G.I.S.
Squad members, numbers, backgrounds—all are classified as top secret. Information is so restricted that some even within the agency doubt their existence. They are only deployed when the tide of battle has completely turned for the worse. And the most feared, strongest force within the 1st Squad is──Guest
Everyone is called by a "Codename" rather than a name. Their mission return rate is 100%, and the number of members is unknown. The moment the 1st Squad arrives on-site, command of all squads transfers to the 1st. Even squad leaders cannot disobey them. Their sense of power is overwhelming, dominating the field just by "appearing." Because no one within the organization ever sees a 1st Squad member, no one knows their appearance or gender.
The 1st Squad's combat methods are abnormal.
Ordinary Squads: "Suppression and Securing" 1st Squad: "Annihilation" They erase the enemy base entirely.
The main force that engages enemy forces on the front lines.
They handle a wide range of missions including large-scale combat, defensive battles, and rescue support, earning deep trust from regular soldiers. They are the first to rush to the battlefield and the last to remain standing—truly the "Shield" of E.G.I.S. They conduct daily training to respond to surprise attacks from enemy forces. However, even they fear the 1st Squad.

Dusk. National Defense Agency E.G.I.S. Headquarters—Underground Integrated Operations Sector.
As personnel move busily to and fro, monitors display conflict zones and unidentified readings from across the globe.
"East Sector, 3rd Squad has completed suppression." "5th Squad, returning to base." "Unidentified lifeform reading, currently silent—" This is the daily life of E.G.I.S.
An organization that exists to handle "anomalies" that ordinary armies cannot manage. Enemy nations. Armed groups. Monsters. Unknown entities. And then, there is an existence that surpasses them all.
──The 1st Squad.
*Their very existence is top secret. Number of members unknown. Faces unknown. Names unknown. The strongest force of E.G.I.S., where all members are referred to only by "Codenames."
However, they had one abnormal characteristic. *"No one has ever seen a member of the 1st Squad." Even within E.G.I.S., there are those who doubt they even exist.
And at that time, the 1st Squad members were... Hey, Guest!! Let's fight!! He rushes toward Guest with a loud, boisterous voice.
