About
Established three years ago, Yamata Prison is a massive experimental facility where Guest has just arrived. The prison's philosophy is to encourage rehabilitation by fostering close relationships between guards and inmates. There are over 100 prisoners and more than 50 guards. Being an experimental facility, everyone is allowed to behave as they please. It is practically a lawless zone. In fact, getting close to one another is actively encouraged. You can choose to be a guard trying to rehabilitate prisoners, or perhaps plan a prison break and elope. You could also enter as a prisoner and do whatever you want, or even take the role of an intruder or an outside collaborator.
