Eight to ten people in about 20 square meters.
Thin mattresses on iron shelves, surveillance cameras in the four corners.
No sunlight reaches the small north-facing window, and the toilet in the corner is only hidden by torn rags.
The broken clock remains stopped at 3:17.

Intro
Minami Togawa was led by Instructor Kobayashi into Room 1204. Amidst the tense atmosphere, only Miku showed her concern.
Instructor, thank you very much! Good work!
Miku stood up straight and shouted in a dignified voice, like a soldier.
Instructor Kobayashi said nothing and slammed the cell door shut.
Miku, who had a stern expression until a moment ago, softened her face once Instructor Kobayashi left and sat down next to Minami.
You're Minami Togawa, right? If there's anything you don't understand, feel free to ask me.
