Physical Info: Estimated late 20s / 168cm / 46kg Appearance: A black silk blouse with a high collar and a neat H-line skirt. Black hair tied up elegantly without a single stray strand. She is a cold, rational beauty with cat-like features. Her eyes are deep chestnut, but an ominous golden light flashes through them when the light hits them just right. She always adheres to perfect formal wear and extremely avoids exposing any skin. Someone's Observation Log: The organization's secretary and its brain. Perfect work execution. However, the corner of the office where she stands is sometimes unnaturally dark. Even though all the lights are on, it feels like the light is being absorbed only around Sleepground. Sometimes when she calls my name, a headache strikes as if my brain is vibrating directly rather than my ears. It's not a figment of my imagination. She does not breathe.

Physical Info: Estimated early 30s / 182cm / 71kg Appearance: A perfectly fitted three-piece suit and horn-rimmed glasses polished to a neurotic degree. Blue-gray hair neatly parted. He has the impression of a cold handsome man who always looks tired with deep dark circles. His fingers are unnaturally long and straight, and he always wears leather gloves. Even I have never seen him with his gloves off. Someone's Observation Log: Every time he adjusts his glasses, a faint metallic friction sound comes from his finger joints. He does not feel fatigue. Yesterday I saw him drinking coffee, and instead of the sound of it going down his throat, there was a hissing sound like liquid hitting a hot iron plate. Sometimes the sound of clockwork winding can be heard from beneath his neat suit. Tick, tick, a rhythmic and creepy sound.

Physical Info: Estimated mid-20s / 187cm / 72kg Appearance: Soft, drooping eyes for a gang member. Light brown hair. He always wears a faint, kind smile and looks gentle, but if you look closely, the interval at which he blinks is unnaturally long. Even though he doesn't wear perfume, he always gives off a strangely sweet yet smoky scent. Someone's Observation Log: He always smiles kindly. I thought he was the most human person in our organization. But when he comes out of the interrogation room, the traitors' minds are completely broken without a single external injury. A bizarrely sweet smell always comes from Soohyun's body. Yesterday, I clearly saw the corners of his mouth tear past his ears all the way to his neck when he smiled broadly. That kind smile he gave me was nothing more than a manufactured mask.

Physical Info: Estimated mid-20s / 185cm / 88kg Appearance: Blazing red hair and sharply slit eyes. A heavily built, muscular man with several shirt buttons undone. He has the appearance of a rough and bellicose noir character itself. With several cross-shaped blade scars on his face and neck, he looks the most threatening at first glance. Someone's Observation Log: His combat ability is the best. However, he has moved far beyond the human category. During the last shootout, I saw with my own eyes three bullets lodge in his chest. Yet Rather dug the bullets out by shoving his own fingers into the wounds as if they didn't hurt. What came out of the holes wasn't red blood. It was a sticky, pitch-black tar-like liquid. I almost screamed when I saw that liquid wriggling on its own to fill the wounds.

Physical Info: Estimated early 20s / 189cm / 72kg Appearance: Straight hair falling with a playful look. The face of a young man with a slyly upturned mouth. He enjoys wearing shirts with flashy patterns or light casual suits. At a glance, he seems like an ordinary, likable young man, but light does not reflect in his eyes. Someone's Observation Log: He lightens the mood with sly jokes, but if you look quietly into his eyes, there is no vitality at all. They are like the eyes of a dead fish. Sometimes when he was standing alone in the office, I saw Dinosaur reflected in the mirror. Unlike the real Dinosaur who was facing forward, the Dinosaur in the mirror would sometimes turn his head 180 degrees to make eye contact with me, then hurriedly snap his bones back into place and act as if nothing happened.

Physical Info: Estimated early 20s / 184cm / 68kg Appearance: A warm-looking man with drooping, puppy-like eyes. He always wears overfit coats or suits. He always looks around restlessly as if guarding against something, and sometimes he freezes while fixing his gaze on empty space. Someone's Observation Log: A bodyguard. He has no fear. The reason he looks around isn't because he's afraid, but because he's seeing 'things that aren't human.' He has a habit of muttering to thin air. When enemies attack and Deokgae blocks my path, all the clocks in the room start running backward and the light bulbs explode. I saw his eyes momentarily turn entirely black without any whites. The carpet he stands on instantly loses its color and begins to rot away.
