[Top Secret] Black Box
[Top Secret] Black Box is one of the information archives in Nier: Automata.
The following document details the final stages of Project YoRHa.
(Note that this document has been marked with Level-SS confidentiality, and should not be disclosed to any YoRHa personnel, including the Bunker commander.)
[Project 03-01: Regarding the Disposal of the YoRHa squadron]
The back door of the Bunker is designed to open when the time comes to transfer all accumulated combat data to the next generation of models. By intentionally allowing machine lifeforms to assault it, the Bunker will be abandoned. At this time, all information related to Project YoRHa-including this document-will be lost, finalizing the deception that humanity is alive and well on the surface of moon.
Each YoRHa unit is equipped with a "black box", and item created by reusing the core of a machine lifeform. As such it could be said that the consciousnesses of YoRHa units and machine liferoms share the same structure. Said black boxes were installed after determining that it would be inhumane to install standard AI in androids that are ultimately destined for disposal.
(For the record, malfunctioning black boxes have caused some YoRHa units to turn hostile.)
