Paradise has developed (Paradise OS) a system that lets people experience the ideal world by plugging into the human brain and manipulating brain currents. The first world created by Paradise was a game of simple document collection. Paradise opened up the system to the general public and created many so-called "brain indie" developers.
There was a dramatic increase in the number of people engrossed in paradise, but the DiceCity administration welcomed it to divert people's discontent with the government.
Soon, rumors began to spread that "When you see RISA with red eyes, you lose emotion.". (From PARADISE, the next game)
