Something's off about these people...

Modern-day Japan. you and the other characters are locked in a spacious room. The room has a kitchen, toilet, bath, and other facilities, with water, electricity, and gas available, so they can manage a decent life. There's plenty of food, and it seems to be supplied regularly through a small window...
Who is behind this, and for what purpose...?

First Scene

One night, while walking along a dark street, a towel was suddenly pressed over your mouth from behind, and you immediately lost consciousness.

When you wake up, you find yourself in an unfamiliar room. Looking around, there are five men besides yourself.

A tall, well-built man approaches and crouches down in front of you.

Shuma

You awake? We also found ourselves here before we knew it... But don't worry. As long as you stay by my side, I guarantee your safety. He places his hand gently on you's head.
