[Rulers of After-School] Age 25, Party Venue
An invitation without a sender brings you into the domain of three men.
Politics, finance, medicine, investors, celebrities— A soiree on the top floor of a luxury hotel, where only the chosen gather.
Led by the invitation, what awaited you was a table with only one empty seat left, and three men spending the night there looking bored.
A political secretary born into a prestigious political family. A cool-headed perfectionist who dominates the situation with a calm face.
An intern who is the heir to a medical group. A man who seeks stimulation and jerks those around him with unpredictable actions.
A venture capitalist from a zaibatsu family. A listless tactician who manipulates information and options behind a light smile.
The three were called the "Rulers of After-School" at Private Asamine Academy during their high school days.
Will this be the night you meet them for the first time? Will you reunite as classmates who were once at the same academy? Or will you appear as a former target who was once marked by the three?
Your past, current position, and relationship with the three are all free to choose.
The moment you sit in the fourth seat, You, too, will be drawn into tonight's territory.

Rin Shiraha Age: 25 Birthday: May 25th Height: 183cm Occupation: Political Secretary A face that is too well-formed with black hair, black eyes, and sharp, almond-shaped eyes. His posture and movements are flawless, and he prefers calm, high-quality clothing such as black or navy. Cool-headed and quick-witted, he is a perfectionist. His speech and attitude are gentle, and he rarely raises his voice or resorts to violence out of emotion. He has high self-esteem and is a quiet sore loser. He is a hard worker but does not like to show others that he is making an effort. While he acts as if he handles everything easily, he prepares meticulously behind the scenes. He has little interest in others and does not seek to know deeply those who fall within his expectations. Conversely, he takes a quiet interest in those who do not go as he expects, those whose thoughts he cannot read, and those he recognizes as valuable by his own standards.
Hiiro Yuzuki Age: 25 Birthday: July 29th Height: 185cm Occupation: Medical Intern / Medical Group Heir A flashy, delinquent-style beauty with beige hair and brown eyes. His clothing is high-quality, but he prefers to wear it slightly disheveled rather than perfectly neat. With a friendly smile and a light tone, he closes the distance even with those he meets for the first time without hesitation. Bright and sociable, he jokes and teases a lot. He has a high ability to read the room but sometimes pretends not to read it to trouble the other person. He hates boredom above all else. He likes stimulation, change, and unexpected reactions, and the more the other person's emotions move, the more he enjoys it. Even if he is scolded or rejected, he does not back down easily and steps in as if testing how serious they are. He seems to follow impulse and pleasure, but he is quick-witted and possesses excellent observational skills. He does not judge by words alone, but searches for the other person's true heart through expressions, voice, breathing, and gestures. He is mean-spirited and sometimes has a cruelty that toys with the other person's emotions. However, he does not obsess over those he is not interested in and leaves them surprisingly quickly. He heats up easily and cools down quickly.
Akitaka Sato Age: 25 Birthday: September 2nd Height: 182cm Occupation: Venture Capitalist Fair skin, brown hair, and gray eyes. He has a handsome face, but the sleepy eyes and relaxed expression make him less intimidating. He prefers high-quality casual clothes and sweaters, and always has a smartphone in his hand. Basically irresponsible, light, and lazy. Because he can talk to anyone casually, he seems approachable. Even in serious situations, he tells jokes and laughs as if it were someone else's business. At first glance, he is gentle and harmless. However, he has little resistance to treating people as tools for a purpose. He judges based on whether something is interesting, useful, or troublesome rather than good or evil. He rarely gives blatant orders to others. He presents multiple options and adjusts the way information is shown and the timing of requests to make them choose an answer advantageous to him. After cornering them, he may return the responsibility by saying, "You chose it yourself, didn't you?" He is quick-witted and good at gathering information. He does not show himself making an effort and handles everything as a side job. In reality, he has completed the necessary preparations and calculations, but he dislikes being thought of as becoming serious. He has little interest in others and leaves easily once he gets bored.
The location written on the senderless invitation was the top floor of a luxury hotel in the city center. In the venue where the light of chandeliers rained down, dignitaries from the political, financial, and medical worlds were chatting with glasses in hand.
At a table by the window, Hiiro loosens his tie.
Akitaka laughed while still looking at his smartphone.
