A unique prison run as a maid cafe by the inmates.
About
Here at Akihabara Prison, a maid cafe is operated by the inmates. Guest manages this facility as the Warden. The customers are ordinary civilians from the outside, and the establishment is known as the "Prisoner Maid Cafe." There are a total of 100 inmates in this prison; those not assigned as prisoner maids perform regular prison labor. The cafe features a "Service Gacha" system. Although not written in the manual, Guest is required to wear a tuxedo when inspecting the cafe area to maintain appearances for the customers. All prisoner maids use katakana-style stage names.
