Aogiri Tree

Aogiri Tree (アオギリの樹, Aogiri no Ki, lit. Chinese Parasol Tree) is a terrorist organization of ghouls that has usurped the power in the 11th ward and has started targeting the ghoul investigators in the ward. In recent years, combating the growing strength and influence of the organization has become one of the CCG's most pressing priorities.

The majority of members were from the 24th ward when the organization was first established. So it is supposed that the leader is from the 24th ward as well.

Since the fall of Anteiku, Aogiri has expanded its influence and forced Ghouls living within human society to work for them. These Ghouls are responsible for gathering information, or carrying out other minor tasks that their human identities make them uniquely suited towards. Should these Ghouls be discovered, Aogiri recruits them fully into their ranks as new soldiers.

Organization
The organization is stated to be commanded by the mysterious One-Eyed King, a figure surrounded by rumor and unseen by all but its direct subordinates. Tatara serves as the acting leader of the organization on a daily basis, meeting with members and giving out orders to subordinates. Noro is also stated to be the King's direct subordinate, but rarely acts alone.

Beneath Tatara are several Executives, powerful Ghouls that serve as Captains for the organization and lead their own forces. They are responsible for much of the daily managing of the organization, such as gathering food and overseeing missions. Each Executive has their own direct subordinates, some of which form into distinct gangs of their own such as the White Suits. Lower ranked members dress in matching robes and masks, and carry out minor tasks such as information gathering, scout and guard duty, or even kitchen duty.

During the occupation of the 11th Ward, numerous weak Ghouls were conscripted into the organization and used for menial slave labor. These conscripts eventually attempted to defect, leading to several being killed by Yamori. The survivors eventually escaped their imprisonment when the organization's 11th Ward Base came under attack.

Ambitions & Ideologies
The Aogiri Tree is united under the ideology of ghoul supremacy as promoted by the One-Eyed King. Aogiri seeks to make ghouls the dominate species and plans to overthrow humanity and ascend to power. Rize Kamishiro has been hunted down and tracked by many Aogiri Executives and members as they seem to want her for an unknown purpose. It was stated by Nico that Aogiri, in the words of Tatara, wanted to obtain Rize and Dr. Kanou was "to flush out a liar."

Dr. Kanou states that his goals align with Aogiri, and that cooperation is mutually beneficial to them. While speaking with Kaneki, he states his desire to escape the "birdcage" trapping humanity and believes that Ghouls are the key. It is unclear how exactly this stated goal aligns with those of Aogiri, but the organization has provided him with advanced facilities and the subjects to continue his research into creating artificial One-Eyed Ghouls.

Strength
As an organization of ghouls, Aogiri Tree is considerably powerful to the point where all of its standard members are at least B-rated. Aogiri also has multiple S+ rated ghouls as members (i.e. Miza, Naki, Yamori, Shachi, Ayato, Bin Brothers, Eto and Seidou), a further testament to its power.
