GensouKai

The later manga volumes explain how the shikigami live an independent existence in a dimension separate from but connected to Meifu. This "imaginary world", GensouKai, is populated by many shikigamis. Like the Meifu, GensouKai appears to be an individual realm and society in its own right. Interestingly, the shikigamis inhabit the world in their human forms (avatars). When he visits, this causes much confusion for Hisoka, who searches for a "tiger, or a red bird", ignorant of the fact that the shikigamis in their own world do, in most cases, resemble humans.

GensouKai is allegedly ruled over by an Emperor. However, the "Golden Emperor" as he is known, has not been seen for many years. It is thought by some that he is dead. The Emperor's representative is Souryuu, the Protector of the East.
