The residential area of the Uehara Race.
Strictly speaking, this should no longer be called just a residential area.
The Shinigami within the Quiet Spirit Court like to refer to the residential area of the Uehara Race as "Uehara Castle," because it sits at a central point within the Quiet Spirit Court and spans over a hundred spiritual miles.
The entire city is divided into an Inner City and an Outer City.
Whether it's the Inner or Outer City, the city walls are all made from Sekkiseki, a specialty of the Soul Society. This material can completely isolate spiritual particles and spiritual pressure, forming a double barrier.
If a soul from the Drifting Spirit Town wishes to infiltrate the city of the Uehara Race, they must first break through the Sekkiseki Barrier of the Quiet Spirit Court, then the Sekkiseki Barrier of the Outer City of Uehara Castle, and finally the Sekkiseki Barrier of the Inner City, before having a chance to face the current Patriarch of the Uehara Race...
Whether in the Inner or Outer City, there are always Shinigami Squads patrolling the city walls daily. Their duty is to protect Uehara Castle from being invaded.
In fact...
They are merely akin to ordinary guards.
Behind the walls of the Outer City is the bustling Outer City District of Uehara Castle.
The entire Outer City District encompasses training grounds, production areas, residential zones, commercial streets, the Academy of Spiritual Arts, hospitals, and many other facilities, effectively becoming a miniature Quiet Spirit Court.
The entire Outer City District houses all the Shinigami and their families who have sided with the Uehara Race over the millennia in the Soul Society. Even if some Shinigami have depleted their spiritual power and perished, their descendants and families are still allowed to reside here.
Moreover...
Most of these descendants will attend the Academy of Spiritual Arts created by the Uehara Race. Considering the timeline, the Academy of Spiritual Arts of the Uehara Race has actually existed longer than the one in the Quiet Spirit Court.
The teachers at the Academy of Spiritual Arts assess based on performance, specialties, talent, and interests to decide whether these members can work within Uehara Castle or become family Shinigami.
This is equivalent to raising children from a young age until they grow up.
This is also a point of envy for many souls in Drifting Spirit Town.
Because once they join the Uehara Race, it means they never have to worry about the future again, and only need to focus on training or studying diligently.
Even those unfamiliar with the Uehara Race can gather bits and pieces of information from the affiliated Shinigami of the Uehara Race, understanding that the family heads of the Uehara Race have always been generous to their own people.
Therefore...
This makes many affiliated Shinigami of the Uehara Race fearless, even though they are, in fact, controlled by the Reanimation Jutsu.
Due to the large number of souls and Shinigami residing in the Outer City District, it makes the Outer City District of Uehara Castle more prosperous than any place in the Quiet Spirit Court.
At times, some Shinigami from the Guardian Court Thirteen Squads, when permitted to enter Uehara Castle, particularly enjoy wandering around the Outer City District to buy unusual items.
Because of this...
Many nobles hope that the Outer City District can be opened up.
However, such an idea is not realistic because the true purpose behind the existence of the Outer City District is to protect the Inner City District of Uehara Castle, which is the core area of the entire Uehara Castle.
The defense of the Inner City walls is even more stringent.
On the walls, there are at least ten ten-member squads, with hundreds of Shinigami patrolling back and forth, ensuring that no one can invade the Inner City District.
Even the affiliated Shinigami of the Uehara Race must obtain permission from one of the Thirteen Deadguard to enter the Inner City District.
As the core of Uehara Castle, the Inner City District has very few buildings, only including Uehara Naraku's residence, the Parliament Hall, Research Institute, Hidden Rain Tower, Secret Technique Institute, Reanimation Manor, and the residences of the Thirteen Deadguard.
Compared to the prosperity of the Outer City District...
The Inner City District is exceedingly simple.
The tallest building in the entire Inner City District is the Hidden Rain Tower, situated at the center of Uehara Castle. It is located within the residence of the Uehara Race's Patriarch, yet it has been deserted for years, appearing merely as a symbolic structure.
Nearby the residence of the Uehara Race's Patriarch is a scattered array of the Thirteen Deadguard's residences, which also serve as their training zones.
The Thirteen Deadguard.
These Deadguard are the pinnacle of combat strength for the Uehara Race!
Each Deadguard possesses the power of Captain Level Shinigami, with some of the strongest among them perhaps even exceeding Captain Level strength!
First Seat, Uchiha Madara.
Second Seat, Senju Hashirama.
Third Seat, Gol D. Roger.
Fourth Seat, Edward Newgate.
Fifth Seat, Senju Tobirama.
Sixth Seat, Sarutobi Hiruzen.
Seventh Seat, Namikaze Minato.
Eighth Seat, Uchiha Obito.
Ninth Seat, Uchiha Itachi.
Tenth Seat, Third Raikage A.
Eleventh Seat, Second Tsuchikage Wu.
Twelfth Seat, Second Mizukage Hozuki Gengetsu.
Thirteenth Seat, Fourth Kazekage, Rasa.
These once-souls are all the collections of Uehara Naraku.
Each of them died in their original world, and their souls absorb spiritual power in the Soul Society, restoring their peak strength and even going further.
The first four seats are undoubtedly the strongest existences.
The rankings of these individuals were originally not in any particular order, but perhaps Uchiha Madara has a slight issue, as he always insists on competing with Senju Hashirama whenever they meet... Senju Hashirama, Edward Newgate, and Gol D. Roger are more laid-back.
In general, the first four seats never make a move.
All four of them nearly spend every day training in their residences, and their existence represents the peak combat power of the Uehara Race on display to the outside world.
The remaining nine seats are responsible for handling all matters big and small within Uehara Castle.
