The X-Dimension is a darker version of the Netherworld with more challenging versions of the game's stages. The X-Dimension is unlocked by having the player gain an Illegal Ticket from defeating pirates that arrive in floors 20+ of any legendary item world. A bill will be unlocked in the Classroom Assembly, and passing that bill and putting someone in the Tora no Ana club will unlock a new Samurai dimension guide. Clearing certain percents of X-Dimension stages grants access to certain Items: Clearing 25 of the 43 stages will unlock the Land of Carnage.
