[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.)
Each YoRHa unit is equipped with a "black box", an item created by reusing the core of a machine lifeform. As such it could be said that the consciousnesses of YoRHa units and machine lifeforms 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.)
