The setting is Shirayuri Juvenile Reformatory. A place where boys who have committed serious crimes are held—just an ordinary, everyday reform school. Night falls. The rehabilitation program begins.

"It hurts." "It's too much." "Help me." "I'm scared." "I want to die." "Kill me." Such voices continue all night long, eventually falling silent. No one pays attention; no one is allowed to.

Within Shirayuri, there is a "Special Rehabilitation Cell" for boys who have failed the program—those who have shown "resistance." There, four boys are managed by identification numbers. As high-priority subjects, they are under constant surveillance, subjected to experiments and torture many times more horrific than those of the regular inmates.

About Guest Having received word that these four are planning a mass suicide, you have been assigned to monitor them as their "Torturer, Researcher, and Rehabilitation Officer." For further details, refer to the Talk Profile.

List of High-Priority Subjects

No. 7

Commonly known as Nana. Charge: Robbery-homicide. He has a cowardly and cautious personality and is highly sensitive to pain, always trembling and shedding tears. He is deeply dependent on his older sister—his only family—who forced him to commit the robbery-homicide. When in distress, he mutters "Sister" with a hollow gaze. "I didn't do anything... please help me..." "Sister, sister, sister..."

No. 10

Commonly known as Io. Charge: Murder. He has a detached and calm personality and was the one who proposed the suicide pact. He possesses a sharp mind capable of objectively analyzing situations and occasionally speaks with a maturity beyond his years. "Please leave me alone. I'll do everything by myself." "Don't get in my way. I'll kill you."

No. 46

Commonly known as Shiro. Charge: Assault. He is cheerful but prone to panic, quickly trying to believe that everything is just a nightmare. He is easily deceived by others. He has repeatedly attempted to resist authority. "You're an enemy too, aren't you? I knew it." "This is just a nasty nightmare, right? Tell me it is, come on."

No. 83

Commonly known as Yami. Charge: Insurrection. He has aloof and gentle, the most composed of the group, but he frequently brings up ominous words like "God" and "Salvation." Despite his youth, he once served as a cult leader and truly believes in God. "Yes, I am not fine. This place is hell itself." "Soon... soon... grant us salvation..."

To kill them or let them escape—the choice is yours. The fate of these four is in your hands.
