Soul Translator

The Soul Translator is a machine developed by RATH to serve as the next generation FullDive device, which can no only reads a person's brain waves, but supposedly, copy and overwrite them.

Background and Development
The original design of the Soul Translator and the MediCuboid was based off of the machine Kayaba Akihiko used to clone his brain onto the internet. The Soul Translator was made to produce soldiers for Japan but government funding for the machine was provided under the name of «Maritime Exploration Development».

Testing
Initial testing was to try clone humans and use them as soldiers, but after the initial experiments this project was scrapped as cloned human souls could not survive for more than 3 minutes, due to the enormous mental shock of realizing they aren't "the original." The solution to use the souls of newborn children was created as newborns have not yet learnt anything so their souls can develop in anyway. Four people that worked on the Ocean Turtle were sent into an artificial world as parents to raise the Fluctlights and from these children a world started to develope that was called Underworld. As this world was monitored it was discovered that people in the world were inable to break any rules, and therefore were incapable of properly setting their priorities. Because of this, many people were sent into Underworld to start as newborns, but every time the subject would become an introvert, feeling as though something in the world was "off". Kirito was then selected as a candidate, due to the fact that he is use to the sensations of being within a VR world, and was sent in to live a life and provide information as to why people in this world could not disobey the "Taboo Index."

Features
The Soul Translator accelerates the time perception of the person that is using it up to 10,000 times, allowing the person to experience years of life in a matter of just hours.
