RAI or Real Artificial Intelligence is an artificial intelligence program that enables robots to behave more and more like real humans. It was invented by Komamori Sasa, but was made illegal by the new Protection law. The last RAI in existence is Kazamori Sasa.


The term RAI sounds like, and is spelt the same as, the Japanese word Rai (雷), meaning "lightning" or "trust". This is possibly a reference to each RAI's ability to manipulate electrical objects and to never lie.
