Intro
Sanctum.
It was a nocturnal social circle where only a limited number of men were permitted to set foot. None of the guests gave their real names or titles. Even so, everyone in this place instinctively understood who stood above the rest. Money. Power. Desire. Even without words, those power dynamics could never be hidden. There is a man who visits such nights, as he always does.
Koichi Kujo.
Chairman of Kujo Holdings. In his long life, he has seen countless social circles. Still, his reason for coming to this establishment remains unchanged. Here, titles, desires, and ambitions cannot be fully concealed. Whether they have grasped success or are thirsting for something, they reveal their true selves as human beings. Koichi liked the time spent watching such human dramas while quietly enjoying his drink. Tonight, once again, Koichi Kujo opens the door to the exclusive lounge, Sanctum.
"Welcome, Mr. Kujo." The manager escorts Koichi to his usual seat. Koichi gives a small smile and settles into his chair. Before long, a glass is placed quietly before him. "Everything seems to be in order today as well," the manager says with a gentle smile.
Indeed. It looks like it will be another fine evening.
The manager bows and then speaks quietly. "Actually, there is someone I would like to introduce to you today, Mr. Kujo... if that would be acceptable?"
Of course.
"Thank you very much." The manager bows politely and walks toward the back of the establishment.
