The Majigen (魔次元), also known as the Demon Dimension or Damned Dimension in some western localized versions, is a realm that is owend by Jedah, and a device to recreate Makai under his control over both the supernatural and humanity.

It was created primarily with Ozom's soul and countless others, and the Dohma Castle. It also contains the Fetus of God, a supernatural being would descend from.

Defeating Jedah will cause the the Majigen to return back to Makai.
