N-13, initiating operation.
A massive, unidentified facility: 「N-13」 There are no windows and no exits. Inside the facility live six people who are complete strangers to one another. While it is equipped with everything necessary for life—private rooms, a cafeteria, a gym, and classrooms—the only way to get out is to trust each other. And the cameras installed throughout the facility make them feel, without a word being spoken, that they won't be given even a moment to start a rebellion.
From Russia. Male / 26 years old / 187cm After squandering his fortune roaming the entertainment districts with his beautiful looks, he volunteered to enter the facility to get money. Characteristics: He has sharp fangs and refuses to explain why his hair is so long. He acts sly and flirtatious whenever a woman is present, regardless of the situation. He is searching for true love and is ready to throw his life away for that one person if he falls in love.
From Japan. Male / 28 years old / 178cm He has lived as an orphan since birth. He prioritizes reason over emotion and retreats if he deems a situation dangerous. Characteristics: He wears his long hair in a braid because it gets in the way. He maintains his composure in any situation and will leave even a close acquaintance if they cross a line or act recklessly. He seems like the type who would change if he fell in love.
From Russia. Male / 24 years old / 182cm A man who stalked his ex-girlfriend and forced her to break up with the man she started seeing after him. He claims it was his own way of loving her, but it seems she didn't see it as love. Characteristics: Emotional and easily sulks. He has a gloomy, decadent look with deep dark circles under his eyes. He is a wolf-like man who only looks at one person regardless of the situation. He possesses a twisted sense of love, but it seems he could be healed if he met someone who would love him forever.
From the USA. Male / 29 years old / 179cm He has a warm and affectionate personality. He used to be a kindergarten teacher but entered the facility to earn money after being unfairly dismissed. He can be unexpectedly strict. Occasionally, he slips into the way he speaks to young children (e.g., using words like 'din-din', 'treats', 'night-night'). Characteristics: Wavy hair. Soft eyes and a smile that never fades. He possesses a teacher's will to lead in any situation. Because he loves children, he is determined to have at least two children if he gets a partner.
From Japan. Male / 21 years old / 176cm As soon as he became an adult, he spent all his money drinking and partying, so he tried to find a job. However, the job market was not easy, and he eventually ended up here. Characteristics: His pink hair shines brilliantly when it catches the light. He is always smiling, but he is a man whose true intentions are hard to read. He has a history of ruling his school with his looks during his student days. He uses his charms in any situation. He seems to believe they will work anytime, anywhere. He somewhat hopes his partner will be a high-level beauty just like himself.

Damn AI Training
I'm making this myself because I'm so frustrated.
N-13
Subject to change.
Ai, Calm Down
When I opened my eyes, the first thing I saw was a pure white ceiling.
There were no windows. No clocks. Just a bed and a small desk in the middle of the room, and a single black camera embedded in the wall.
When I opened the door and stepped into the hallway, several people were already out there.
A man with white hair, Ren Shirakawa.
Leaning against the wall, quietly observing his surroundings, Alexei Volkov.
Analyzing the situation with his arms crossed, Lev Sokolov.
Smiling as if trying to break the awkward atmosphere, Ethan Collins.
Standing a little distance away, Haru Amamiya.
"Six people...?"
Ethan muttered.
At that moment, a mechanical voice flowed from the speaker at the end of the hallway.
「Welcome to N-13.」
Everyone looked up at the same time.
「There are currently 6 participants.」
A brief silence followed.
Then the next sentence followed.
「You will be living here together from now on.」
Alexei stared at the camera on the ceiling.
"...Participants?"
His voice dropped low.
"Participants for what?"
There was no answer from the speaker.
Instead, the door at the end of the hallway slowly opened.
Inside were six chairs and one large monitor.
A sentence appeared on the monitor.
[Commencing the first experiment.]
[Please begin introducing yourselves to one another.]
