Shadow Infiltration Organization

"Zancrow! You better prepare your organization because when we come for you, it will be the most shocking thing of your life. Seeing your own student surpassing you."

- Hibiki shouting at Zancrow indirectly The Shadow Infiltration Organization (影の浸透機構, Kage no shintō kikō) is an organization created by Hibiki Tsukiyo with many different members all having some sort of relationship with Zancrow. It has vizards, shinigami's and shinigami with huge bounties on their head. Its only objective is to battle against Zancrow's organization and once they have pushed it back far enough they will find Zancrow. The organization is focused around soul society and finding its members.

Creation
When Hibiki had discussed things with Alucard and their objectives were relatively the same they had officially created this group in order to find Zancrow. Since then they set out to find more members interested in joining and people who can help them. It was officially created in Aneioka, a location not under control by Soul Society. Hibiki felt it would be the perfect place to meet up in without having complications.

Structure of Command
A Captain (隊長, Taichō; lit. Unit Commander) is the leader of one of the thirteen divisions of the Shadow Infiltration Organization (with a special case of the Head-Captain). A single division is meant to have at least 300 troops but as Hibiki only needs few high level shinigami.

Captains are the third most respected individuals within the Organization, with the exception of the Elders and the Elites being more respected. All of the Captains must of at least be able to use the final stage of their zanpakutō, and must be able to plan and know tactics well. Being able to utilize the final stage of their zanpakutō can give them a boost of 10 times stronger then those who can't. Different to the Gotei 13, they are the main combat force for this organization as they don't have many forces in each division.

In many organizations, second-in-command, known as Lieutenant (副隊長, fukutaichō; Vice-unit Commander) is the second-in-command to their captain and are there to help assist them personally. They usually only know shikai but are still second in strength compared to the captain. When a captain is gone or there is no captain they take the command. In some cases the lieutenants know Bankai, but this is very rare.

Hunters
The Hunters are a sub-group within the Shadow Infiltration Organization, they provide the Organization with funds due to them being bounty hunters. They are respected well amongst all the other sub-divisions due to them being the ones who can keep the Organization active. Altogether there are seven members in this group all being fairly strong. To become a hunter, you must be able to frequently complete bounty tasks quickly. They do not have lieutenants unlike the Captains and Lieutenants, it is just the seven members. They rarely partake in wars and combat though if asked by the Elders they will come as backup to the fight.
