Soul Dimension

The Soul Dimension (ソウル次元 Sōru Jigen) is the Dimension where all Duelists use Soul Monsters. Compared to the other Dimensions, the Soul Dimension is more so fantasy-based. It's appearance is that of a world similar to that of an RPG, in that many of the Duelists are adventurers, and travel around, complete quests that usually involve the finding of rare cards or defeating strong opponents and things of that nature. Duelists are even able to "level up" themselves by gaining points from quests completed, in typical RPG fashion.

's counterpart in this Dimension is Yube, a young adventurer who wishes to reach the highest level possible (rumored to be 999,999).
