Soul Society

is an afterlife (also called the spirit world). This is also where Shinigami live and is where most Souls dwell until they are reincarnated into the Human World.

Overview
While Rukia Kuchiki initially describes Soul Society as something of a paradise, where nine out of ten times it is better than the living world and hunger is never a problem, Soul Society is far from sublime. In fact, aside from the slowed aging and aforementioned lack of hunger, life there is much like that in the living world.

Soul Society consists of the, where souls live when they arrive in Soul Society, and , which is at the center of Soul Society. The mode of life here closely resembles that of feudal Japan.

The Human World and Soul Society are parallel to each other and are two sides of the same coin. Families separated by death are rarely reunited in the Soul Society unless they arrive in Soul Society together. People live nestled together like a family of strangers. One never gets hungry (if she or he doesn't have spiritual powers) and aging is slowed to a great extent, with lifespans of 2000 or more years not being unheard of, though such ages are limited to Shinigami or other Soul Society dwellers with high spiritual power. Children can be born as they are in the Human World. People can also be killed as regular Humans are, though they are capable of surviving wounds that would normally be considered fatal. A soul that dies in Soul Society is reincarnated on Earth as a new Human with no past memories.

Accessing Soul Society
Shinigami enter and leave Soul Society by unlocking the Senkaimon and using a Jigokuchō. Pluses, on the other hand, enter Soul Society through the ritual of Soul Burial. When people die, they are assigned a number to a part of Soul Society according to when they died. Spirits can be born in Soul Society as much as in the living world, with the Shinigami acting to balance the souls.

Intruders can pass through the Senkaimon in the same manner, but only in soul form. This allows spiritual beings, such as Ichigo in his Shinigami form, to enter without permission. Humans can also use such a gate through the use of, which convert solid matter into Reishi's.

Finally, Hollows can also directly rip a hole to Soul Society from Hueco Mundo, or in the case of Arrancar, using a Garganta.

Spirit King
Soul Society is ruled by the Spirit King, who commonly leaves the running of Soul Society to the Central 46 Chambers and Nobles. The Spirit King lives in the Royal Palace in a separate dimension in the very core of Soul Society, which is protected by the Royal Guard. The King does have a specific system of "speciality duties" which are actively carried out but the exact nature of these duties is unknown. The dimension can only be opened with a tri-pronged golden key fittingly named the. The location of this Royal Key is passed down verbally from one Gotei 13 Captain-Commander to the next, the current holder being Genryūsai Shigekuni Yamamoto. According to Rangiku Matsumoto, no Shinigami has ever seen the king.

Nobility
Another part of the government are the, especially the four Great Noble Houses, which are considered to be the highest of them all. The lower noble houses all serve one of the four each.

Judiciary

 * The Central 46 serve the Shinigami royalty. They are made up of 40 wise men and 6 judges, selected from all of Soul Society. They are sealed into an enclave in Seireitei called which no one else may enter, regardless of their military or civilian status. They act as a supreme judiciary organization whose authority puts it in direct control of the legal system. They handle all rulings on Shinigami and souls who have violated prohibitions. Their orders are absolute and no decision has been known to be overturned.

Laws

 * The ultimate law is to maintain balance.


 * It is against the law for a Shinigami to give their spiritual power to Humans.


 * It is against the law for a Shinigami to use forbidden Kidō.


 * It is against the law for any citizen of Soul Society to create weapons of a dangerous nature not sanctioned by the feudal government. To do so is treason.


 * It is against the law to attack a captain. To do so is treason.


 * It is against the law to commit terrorist action(s) or attempt overthrow of the balance of Soul Society. To do so is treason.


 * It is against the law to commit murder.


 * It is against the law to kill a Human that a Shinigami has not been ordered to kill.


 * It is forbidden for a Shinigami to acquire or attempt to gain Hollow-like powers.


 * It is a crime for a Shinigami to remain in the Human World longer than a certain time limit.


 * It is against the law for the Gotei 13 to meddle in the affairs of the noble families unless the family in question breaks one of the laws of Soul Society beyond a shadow of a doubt.


 * It is by ancient law that two Shinigami cannot hold the same Zanpakutō. They must fight for the honor of bearing the spirit, with the spirit going to the winner, and the loser being executed.


 * It is forbidden for a Shinigami to intervene in anything that is related to Hell.

Punishment

 * Exile: Certain crimes allows for the punishment of exile, commonly stripping a Shinigami of their powers and banishing them to the Human World.


 * Detention: A punishment not well known among the citizens of Soul Society is the detention of Shinigami. It is commonly reserved for those who have either broken the law, quit the Gotei 13 or those who just seem dangerous and mentally unstable (as per the government's interpretation). This is carried out by the Onmitsukidō.


 * Imprisonment: The Central 46 can sentence a Shinigami to be held in an underground prison for a set amount of time. The prison has eight levels, which prisoners are confined in based on the severity of their crimes. For the use of forbidden Kidō techniques, Tessai Tsukabishi was sentenced to be confined in the Shugo, the 3rd level of the prison. For the crime of treason, Sōsuke Aizen was sentenced to be imprisoned in the 8th level, called Muken.

There are two known forms of execution in Soul Society:


 * Spirit-sealing pit: The spirit-sealing pit is an ancient form of execution in which Shinigami criminals are thrown into a pit walled with sekki sekki rock – a type of stone that absorbs spiritual power, preventing those nearby from using their powers. Hollows are then thrown into the pit with the criminals as the means of execution. The practice was considered too barbaric and discontinued.
 * ': The "ultimate punishment", Sōkyoku is a form of execution usually reserved for those with extremely strong spiritual powers, namely Shinigami captains. The Sōkyoku is a giant halberd that utterly destroys a soul on contact. When released, Sōkyoku takes on the form of a phoenix, its true form, called Kikōō'. The Kikōō has the destructive power of a million Zanpakutō, and that power is multiplied by a factor of 10 at the moment it pierces its victim. It was destroyed by Jūshirō Ukitake and Shunsui Kyōraku.

Military
The armed forces of Soul Society consist of three independent main branches: the Gotei 13, the Kidō Corps and the Onmitsukidō.

Gotei 13
The is the organization which most Shinigami join. It is split into thirteen divisions (hence the name), with several divisions having certain specializations. The 4th Division is the medical/supply division, the 11th Division is the combat division (specialization in swordsmanship), and the 12th Division is the research/scientific division. The 9th Division is in charge of newspaper and magazine-related duties. It's unclear if the other divisions are specialized, as the four above are the only ones who receive any significant attention apart from their members. Additionally, it should be noted that Suì-Fēng is in charge of both the 2nd Division and the Onmitsukidō. The Gotei 13 somewhat seems to have superiority and little authority over the two branches (i.e., Suì-Fēng, the Commander-in-Chief of the Onmitsukidō and Tessai Tsukabishi, the former Grand Kidō Chief).

Royal Guard
Also known as the Zero Division, it is made up of former captains of the Gotei 13 who have been promoted to this level. Only captains of the Gotei 13 know of their existence. They are said to have considerable power and tactical knowledge. Only the Royal family presides over them, the Central 46 have no say in them what so ever.

Kidō Corps
There is currently little information on the (known as the Kidō Force in English), due to the secrecy in which they operate.

Onmitsukidō
There is little information about the operations of the Onmitsukidō. They are currently lead by Suì-Fēng, who is also the captain of the Gotei 13's Second Division. She succeeded Yoruichi Shihōin in both posts.

Technology Level
One of the more unusual aspects of Soul Society is its technology level. While the lifestyle and culture of Soul Society is comparable to feudal Japan, they possess technology of a level exceeding that time period. The Shinigami Research Institute has developed amazing technology to their credit, mixing technology with organic components. Allowing for the creation of creatures that do everything from detecting spiritual energy signatures to allowing Humans to see a spirit without the use of a Gigai. They possess touch-screens and databases which are in use for files and historical documentation storage found extensively in the, which contains all the knowledge and history of Soul Society. View screen technology that is capable of sending signals to the Human World and Dangai, allowing for face to face conferencing. All manner of portable hand-held devices for tracking and communication purposes. Blending old traditions and ideas with new innovation, Soul Society is an enigma in this comparison.

Rukongai
is the largest portion of Soul Society and the most populated. It is divided into 320 districts (80 in North Rukongai, 80 in West Rukongai, 80 in South Rukongai, 80 in East Rukongai)

Seireitei
is in the center of Soul Society, a circular shiro with four main entrances, each guarded by a Gate Guardian. The walls of Seireitei are made of stone called, a material known to negate all Reiryoku, similar to magnetic lodestones. The stone also forms a spherical barrier around the city which stops anything spiritual from breaching it.
