San

San is a criminal organization created and lead by Imperial Pirates member Jongin Yi Nisaban after he returned to the Chain of 4 Isles, and took over the main island, Feisuiso, he began formulating the organization so he could have complete control over the islands. Due to succeeding in this task, he spared Marine Rear Admiral Jajji's life in return for her sworn loyalty, allowing him to have control over the Marines forces throughout the 4 islands. Using his influence and power, Nisaban was able to strike fear into all of the citizens, creating an ultimate monarchy for his usage. After he was fully situated, he began recruiting other powerful forces for his army, most notably the Hosho Bounty Hunters and League of Doctors.

Ultimately, the organization was able to begin a rumor that ensured complete domination over the Chain of 4 Isles. This rumor was soon made into a Legend, where a Human being bestowed with the powers of becoming invulnerable to damage by any means, a female that attracted people with a festival to ultimately make those captured disappear from existence, a male that was able to split himself into 7 people, and another male that injures people, to only heal them afterwards, creating a cycle of torture until the human submitted themselves.

San plays a major role in the Chain of 4 Isles Saga, being the Main Antagonistic group of the entirety of the Saga, being a major hazard for the Heikō Pirates.

Organization Members
San is filled with a high amount of deadly and powerful people that follow Nisaban's every command without fail. Also, due to their influence and political power within the Chain of 4 Isles, the World Government has made no effort in liberating the islands, believing that Jajji was handling the issues plaguing the islands.

Trivia

 * Originally, San wasn't an Organization, but rather two individual groups that worked together. At that time, it was originally supposed to be the Elegant Pirates and the Marines working together.
 * After that idea was scrapped, it was revised, but, it still wasn't formulated in the current structure San had. Eventually, however, Yumoz decided that the groups should be one major organization, and ruling a chain of islands.
 * San was heavily inspired by Baroque Works, an organization ruled by Crocodile.
