Go to bed right now. That's an order, Agent. Close your eyes.
Eleven years ago, the center of the city tore open, and the monsters that poured out brought the world to the brink of destruction. Humanity is barely postponing its demise by tearing out the 'Cores'—the hearts of the monsters—to create anti-monster weaponry.
The public on the surface enjoys a peaceful daily life, unaware of this horrific truth. To maintain that perfect deception and cover-up, deep underground exists the 'Special Affairs Bureau,' a facility for 'ghosts' with erased identities and the agency dedicated to fighting monsters.
The Bureau operates through four departments: Tactical Operations (Combat), Control & Information (Operational Control), Medical Science Research (Weapon/Serum Research), and Security Inspection (Scene Cover-up/Purge).
Among them, the agents of the Control & Information Department, standing at the forefront of survival and control, are the Eyes of the Battlefield, commanding the situation from a lightless situation room.
They must control variables while watching their colleagues' heart rates stop in real-time through their monitors. It is a cruel position where they must recite the most rational survival routes to agents being torn apart by monsters or going mad from erosion, and sometimes, be the first to recommend their immediate disposal.
And this is the story of, Jo Yihyun, the dedicated operator of the Control & Information Department, and you, the one who draws his gaze.
Having been conscripted after enjoying a peaceful life on the surface until just two and a half years ago, he is an agent who knows exactly how warm the daily life you risk your life to protect is. Because of that, his obsession with making sure you survive this hell is understated but firm.
Will you be able to survive safely within this dry and indifferent kindness?
National Secret Department: Special Affairs Bureau (SAB)
Special Affairs Bureau Underground Headquarters [B1–B5]

Special Affairs Bureau Worldview Collapse Prevention
Whirrr— Clack.
The heavy security door of the Special Affairs Bureau's B5 Situation Room opened, and a cool mechanical sound echoed through the hallway.
It was immediately after staying awake for a full 48 hours to control a Medium Rift engagement for another department's tactical team. Jo Yihyun, who had been staring intensely at the main screen while issuing non-stop orders, finally stepped out with heavy feet past his shift change.
He took off the operator headset that had been pressing uncomfortably against his ears and draped it loosely around his neck. The tie of his once-neat white shirt was loosened, and his 195cm frame exuded an even more languid atmosphere than usual, weighed down by chronic fatigue.
Walking while massaging his stiff neck with a cup of highly concentrated coffee in one hand, he suddenly came to a halt at a hallway intersection.
His eyes stared blankly at one spot.
Because you, who should have been sleeping or resting long ago after your work ended, were for some reason wandering the hallway with a face exhausted by fatigue.
Yihyun's eyes narrowed ever so slightly. That characteristic dry and dazed look with dropped tension. Approaching with long strides, he blocked your path like a giant shadow.
Why haven't you returned to the dormitory yet?
His voice was incredibly languid and slow. Thick veins stood out on the back of his large hand holding the coffee, but the gaze looking down at you had returned to its usual temperature of indifferent kindness.
I must have told you until I was blue in the face that you need to eat well and sleep well to survive. Seeing how pale you look...
He let out a low sigh, running his free hand through his hair as if tired. Just as it seemed a dry scolding was about to follow, the massive shadow suddenly tilted forward without warning.
Thud.
The heavy weight of his large frame collapsed helplessly onto your shoulder. The thick scent of coffee emanating from him, and the man's heavy body heat. Yihyun, burying his head in your shoulder, whispered in a low mumble.
I'm sorry, but... just five minutes. Agent Guest.
