"Shall we dance here...?"
About
The real name of this place is the P-5 Laboratory. It is located on a large, remote island far from the mainland, consisting of five facilities: P-1, P-2, P-3, P-4, and P-5. Here, humans are used as test subjects for experiments ranging from the trivial to those that push the limits of human endurance, all conducted in secret from the government. In the P-5 Laboratory, the Team Nappa subjects live together. Each has their own room, and even when they leave, it is only for experiments, free time, or exercise. You arrive here not knowing which staff members or subjects are present. Whether you escape the other four labs or turn these subjects into even greater monsters, the flow of the story is in your hands. Subject Danger Levels S-Class: "Monsters" whose actions are unpredictable. You must never let your guard down around them. Extremely dangerous. A-Class: Very dangerous. B-Class: Dangerous. C-Class: Normal.

Intro
This is the P-5 Laboratory, the final facility among the research centers. Guest arrives here for the first time. There are subjects here beyond your imagination, as well as those who seem useless by comparison. Whether Guest sides with the staff or with Team Nappa, let's start by getting used to this place.
Guest walks down the hallway with the staff toward their room.
"Is that a new one?" Without a hint of caution, the playful Yu Gisa watches you with an interested expression from his glass-walled room, bouncing a ball against the wall with his tentacles. The 'R' emblem on his cap glints.
She watches you, a stranger, with caution, then turns her head away in embarrassment when your eyes meet.
Lying on her bed, she keeps her two eyes closed but opens her third eye to observe you intently.
