Composition Dimension

The Composition Dimension (次元 Kōzu Jigen) is one of the many Summon Dimensions in Taylor Gorrell's Yu-Gi-Oh! timeline, where nearly all Duelists use Composition Monsters. 's counterpart in this Dimension is Yume, and Yuzu Hiragi's counterpart is Eri.

The Composition Dimension highly promotes Dueling, but rather than focus all its technology on it and make it almost a way of life, it focuses more on Dueling as an activity while other industries grow. However, the Composition Dimension is very much focused on being a civilizaton of fun and games, with many areas of the Dimension having parties for no reason. Duel Disks in this Dimension are similar to the D-Controller model, complete with Game Card compatibility.

During the initial Interdimensional War, the Composition Dimension struck a deal with the Ritual Dimension in response to Academia invading the, having domed settlements constructed for the Ritual inhabitants to live in peacefully that would be guarded by Composition forces. In exchange for the Composition Dimension occupying them, the Ritual Dimension would be provided with Real Solid Vision. The deal worked for some time, but after the War ended, the Composition forces did not withdraw, under the reasoning of protecting them from a future crisis. When the Ritual inhabitants started lashing out at them, authority in the Composition Dimension became uncertain how to handle them, and tensions continue to rise as the Composition Dimension works to prevent a war from breaking out.
