The Human world (にんげんかい, Ningenkai) also known as Ningenkai or Reality is one of the three worlds from the Valis series and almost always the starting point of every game's plot.
The human world is based in our actual real world, being inhabited by normal humans (as its name implies), animals and plants. It is a recurring target of attempted conquest by many of the main antagonists from the series because of Its energy and resources. It's also the recurrent opening scene for most of the games in the series and the homeworld of the protagonist, Yuuko Asou. In the human world is also hidden the Crystal pillar prison where Galgear and his followers were imprisoned centuries ago, the Reddish moon can also be seen from the sky in this world.
