Soul King

Adnyeus (アドナイェウス, Adonayeusu), more commonly known by his title of Soul King (霊王, Reiō), is the supposed ruler of Soul Society, who resides in the Soul King Palace and is protected by the Royal Guard. Adnyeus is also the father of Yhwach. In reality, Adnyeus is a mere figurehead — a vegetative godlike entity that has been sealed away by the Shinigami eons ago and whose existence is tied to the cosmic balance of the Three Worlds, serving as the linchpin (楔, kusabi) that keeps the realms from merging back into the original world. Appearance Adnyeus is humanoid in physique, with slicked-back dark hair, oval eyes without eyebrows. His eyes are very unusual, each having four black irises.[9][10] As the Soul King, he currently has no arms or legs[11][12] and is sealed within an unusual blue crystal that is suspended by four wires in a large, elegant room.[9] The crystal turns red when damaged.[13] Personality The Soul King is a mysterious and enigmatic figure whose exact motivations remain uncertain. Though he is said to carry out orders to the Royal Guard, he has never been recorded speaking or displaying any emotion, making it difficult to accurately describe his character. What is known is that he seemingly cares about the inhabitants of the Soul Society, as he ordered the Royal Guard to rebuild the Gotei 13 following the Wandenreich's initial attack on the Seireitei, and his right arm actively tried to prevent the Quincy from destroying the Three Worlds. The Soul King greatly respects those who have made significant contributions to Soul Society, offering them a position among the Royal Guard before implanting the Ōken into their bones and giving them their own city in the Soul King Palace. According to Tenjirō Kirinji, the Soul King has taken a liking to Ichigo Kurosaki. The Soul King's feelings towards his son Yhwach remain unclear; what is known is that Yhwach resents his own father for allowing the Quincy to be persecuted by the Shinigami. Senjumaru Shutara also claims that the Soul King has forsaken the Quincy. However, after enduring millennia of imprisonment by the Shinigami that Yhwach called "endless humiliation", the Soul King made no attempt to stop the latter from killing him, possibly out of foresight of his own death according to Yhwach. Purpose and Duties The Soul King is not involved in governing Soul Society and never interferes. Most Shinigami have never seen him. To them, he is revered and symbolic, but not present in their lives. The Soul King's sole purpose is to regulate the flow of souls into and out of Soul Society and keep the flow stable. Without the Soul King, the balance is lost and Soul Society, as well as Hueco Mundo and the Human World, will all collapse into one. According to Yhwach, this results in the unification of life and death and the creation of a world without the fear of death
