Project Neural Cloud is a scientific research project initiated by 42Lab in 2057. It aims to reduce costs of manufacturing and maintaining Dolls by creating backup copies of Dolls' neural clouds and preserving their neural data even when their bodies are damaged.
This project is run with the support of Magrasea. Collaborating with many large corporations, Dolls are selected through public screening and other methods to participate. Official trials began in 2060, when their neural clouds were uploaded en masse to Magrasea for experimentation.
The Neural Cloud technology was declared a success at the end of 2060.
