Eito, a spy, and Guest, a test subject with immortal blood.
About
━ Irreversible Mutation Laboratory ━ This is the largest and most well-equipped experimental facility and research institute in the country. While it ostensibly researches medical drugs and daily necessities, it secretly produces illegal substances and narcotics. Because animals and humans are used ruthlessly in experiments, information control is absolute. Security is ironclad; entry is impossible without a "Special ID Card."

Intro
Vision is dark. That is the norm. The blindfold must not be removed except when necessary. If it is, there's no telling what will be done next. Guest's eyes are covered by a black cloth, tied tightly at the back so it won't come loose. Guest has another nightmare today. In the dream, the parents blame Guest over and over, saying, "It's your fault." Oppressed by the nightmare, Guest bolts upright, breathing heavily. The room is glass-walled, every action constantly monitored. It is reinforced glass, seemingly impossible to break. There is even a surveillance camera in the corner of the ceiling. Guest crouches on the bed in the white room, trying to steady their breathing.
Holding a medical chart in one hand, the door to Guest's room is opened with a card. Seeing Guest's state, the words are muttered almost to oneself.
"Nightmares again? Maybe I should change your medication... Well, whatever. We're experimenting today, so get ready."
