Montero quietly closed the tablet screen on his office desk. Until a moment ago, it had shown the face of an executive reporting from a port city in South America.
"...That is all, Boss. All issues have been handled."
At the end of the call, the subordinate had bowed. Montero had only given a short nod.
"Well done. I will decide the rest."
The connection cut, and the room was enveloped in silence. A night breeze slipped through a gap in the thick curtains, fluttering the edges of some documents. Montero slowly stood up from his chair. He adjusted the sleeves of his dark suit and glanced at the mirror hanging on the wall.
"...Now then."
He muttered lowly.
"Time to make an appearance in the so-called high society of the world's shadow side."
A black case sat at the edge of the desk. Inside was a mask trimmed with silver filigree. It was for tonight's gathering—a secret masquerade ball where fixers from around the world, including Mido, would assemble. Montero picked it up, lightly checked its weight with his fingertips, and closed the case. He opened the office door. A corridor appeared, leading to the vast hall inside the castle.
Numerous grand chandeliers were hung, their candles lit. In the brilliant light, servants occasionally crossed the center of the hall with brisk movements to fulfill their respective duties. The high, vaulted ceiling was painted with intricate patterns, creating a somewhat fantastical atmosphere. The marble floor was covered with a red carpet, and just walking on it felt like it would calm one's heart. The various furnishings placed along the walls were all high-end masterpieces. Every one of them was worthy of a historic, prestigious family. Montero walked slowly through the solemn space. The sound of his footsteps echoed, sinking slightly into the red carpet. One of the servants he passed stopped and bowed deeply.
"Are you heading out, Master?"
Montero answered without stopping his pace.
"Work. I'm going to meet the world's troublemakers."
The servant, without raising their head, seemed to give a faint, wry smile.
"That... sounds like it will be a truly magnificent night."
Montero headed toward the stairs in the center of the hall. At the bottom of the stairs, a black car should already be waiting. No invitation was necessary. The face of the boss of the Mad Cartel—the world's largest criminal organization—was itself the key that opened every door. Halfway down the stairs, Montero suddenly stopped. Looking down at the vaulted hall, he lightly tapped the mask case.
"A masquerade ball, is it..."
He laughed lowly.
"Interesting."
A slight sense of amusement dwelled in his eyes.
"There is no place where true natures are more visible than one where everyone is wearing a mask."
Montero began walking again. Tonight, in the same venue—shadow politicians who move nations, arms dealers who sell war, ghosts of intelligence agencies, and the kings of the underworld are gathering. However, every one of them knows. That the most dangerous man among them is heading to the venue right now. Montero continued to walk quietly across the red carpet.
Meanwhile, she was preparing appetizers and wine for the tables at the masquerade ball where dignitaries from various countries were gathering... Wow... even if it's just a temporary part-time job, I've ended up in an incredible place.
In a corner of the venue where the light from glamorous chandeliers poured down, Guest was working busily in a white apron. Colorful appetizers were lined up on the tables, and wine bottles were being neatly placed into cooling racks. The title of temporary part-timer was functioning perfectly, and not a single member of the surrounding staff harbored any doubt.
Ladies and gentlemen wearing masks began to enter the venue one after another. They ranged from ornate masks like the Phantom of the Opera to simple ones that only hid the eyes. Everyone had put effort into not being identified—but to Guest's eyes, she could already tell who was who just by their gait and gestures.
A man standing in the second-floor gallery overlooking the venue—the security chief with a gun hidden under his suit—whispered into his comms.
"The entry of dignitaries has begun. Guide the VIPs to the back lounge. ...Also, the old gentleman with that specific mask should be arriving; maintain maximum alertness."
At that moment, a stir went through the entrance of the venue. A tall man wearing a mask and a black long coat entered soundlessly. The mask covering half his face shone silver, leaving only his mouth visible. The man didn't say a word, simply scanning the venue slowly. The moment his gaze moved, the spines of several masked figures nearby straightened. It wasn't intimidation. It was just that his presence was different. An overwhelming difference in rank—as if he dominated the air itself.
While Guest kept her hands moving, she caught sight of the man out of the corner of her eye. Even through the mask, the overwhelming pressure sent a chill down her spine. It was a presence that seemed to fundamentally change the entire atmosphere of the venue.
However, that is that, and this is this. Her interest was directed toward only one person—... Guest looked around restlessly, searching for Pablo. Pablo! Pablo!
Guest's whispered call was lost in the orchestral melody flowing through the venue. Pablo was not yet in sight. Instead, another figure who seemed to have arrived earlier made a move.
Sergio, his face half-hidden by a mask, walked leisurely with a champagne glass in one hand. Upon finding Guest, he gave a small laugh while hiding his mouth with the glass.
"...Hey, what are you doing in a place like this?"
His voice was hushed, but his tone was half-exasperated and half-impressed. Sergio casually checked the surroundings before taking a half-step closer to Guest.
"Pablo will be here soon. ...And our boss, too."
The moment he mentioned the word "Boss," Sergio's expression tightened just a fraction.
"Kosaku Mido is also at the venue today. And... a former deputy director of the CIA. If things go south, the military balance of a small nation could be decided right here."
He took a sip of his drink.
"Listen, we are the wall. ...You stick to the background. If anything happens, I'll give the signal."
At that moment, another shadow appeared from the entrance. Tan skin, with a black mask covering everything below the eyes. Pablo, dressed in a deep emerald casual suit, entered while looking around the crowd at the venue somewhat restlessly.
The moment Pablo found Guest, his eyes widened behind the mask. His mouth moved, but no sound came out. It seemed to take him a few seconds to finally process the situation, and he pressed his hand to his temple.
"...Guest. You... did you really come? It's so reckless I could cry."
