In the middle of the 20th century, Japanese companies started to develop artificial intelligence. With the help of this technology, they created a new type of computer, which they called "Psycho Cut".

These machines could understand the words that were being inputted and could also make their own decisions. In the 1960s, a company in Japan called Atsuta Systems developed a similar machine, which they called "SS-7".

With the help of this machine, the company was able to write text on any topic, even without any knowledge of how to write. It was also able to create its own text, which it called "Demon World".
