Tatara

Tatara (タタラ, Tatara) is a direct subordinate of the One-Eyed King and one of Aogiri Tree's leaders.

He seems to be from China, and is a former member of the Chinese ghoul organization Chi She Lian.

Appearance
Tatara has short white hair and dark eyes. He hides his mouth with a red iron mask, and is seen wearing a white cloak most times. Whenever he is seen with Eto, he is wearing a large light purple cloak. He is also quite tall, towering over Eto in all of his scenes seen with her.

Personality
As one of the Aogiri Tree leaders and a trusted subordinate working under the One-Eyed King, Tatara comes off as a rather loyal individual. He is portrayed as composed and stoic mostly. He often monitors the activities of the Aogiri executives, but kills in cold-blood when embarking on a mission. He is also proud of his immense stamina when fighting and the accuracy of his calculations as well. Tatara seems to have a taste for precision; as shown when he turns down Kaneki considering he's an artificial one-eyed ghoul. He appears to hold a grudge against Houji, to the extent that even the Quinque associated with him, is enough to make him enraged and lose his near unflappable composure.

Aogiri Arc
After Ken Kaneki is captured by Yamori, Nico and Ayato Kirishima, Kaneki is brought before Tatara. Tatara pierces Kaneki's abdomen so that Kaneki reveals his left kakugan. Because Kaneki's "eye" is no good, Tatara decides that he can not use Kaneki. He decides that Ayato can use Kaneki however he wants. At the end of the meeting, Tatara leaves with Eto because their comrades are waiting for them. Tatara leaves the Aogiri hideout to Noro. Tatara predicts that the doves would come soon and told Noro to follow their plan.

Raid of Kanou's Lab
Tatara is seen interrogating Taguchi about Kanou's whereabouts. Tatara then leaves the room and gives a foot to Naki which presumably belonged to the nurse.

Anteiku Raid
Tatara is seen attacking the reinforcements brought by Seidou during the raid at Anteiku, claiming that the "King" was going to pass by. Tatara is then attacked by a panicked Seidou, but effortlessly grabs him by the neck while recognizing Houji's quinque. Then Tatara throws him only for Noro to take a bite of his arm. A furious Amon charges at Tatara right afterwards and Tatara simply activates his Kakugan while saying "good".

Eto
Their true relationship is a mystery, though it is clear the two work closely together. Eto is almost always seen at his side, and they frequently discuss matters pertaining to the organization. He seems to value her counsel, and readily answers any questions she may have for him. Because of the many mysteries surrounding Eto's role in the organization, it is unclear who has greater authority over the other.

Noro
Noro is the other subordinate of the One-Eyed King, and follows Tatara's commands. An omake suggests the two are actually close, as Eto notes that Noro would be sad if something were to happen to Tatara.

Ken Kaneki
During their initial encounter, Tatara labels Kaneki both useless and a fool. Having made this decision, he discards him, a crucial mistake that comes back to haunt Aogiri. Later on, Eto criticizes him for not killing Kaneki when he had the chance.

Akihiro Kanou
Though a mere human, Tatara seems to have some respect for Kanou's work. They have a cordial, professional relationship once the rogue doctor joins forces with Aogiri and begins performing experiments for their benefit.

Kousuke Houji
Tatara has a fierce hatred for the Investigator, losing his cool simply from seeing a Quinque associated with him. Their exact history is not known, though it relates to Houji's time spent in China destroying the Ghoul organization Chi She Lian.

Seidou Takizawa
Tatara first becomes interested in the young Investigator upon seeing his Quinque, recognizing it as one that Houji had made from another Ghoul named "Fei". He takes his rage out on Houji's subordinate, handing him over to Noro as a snack. However, two years later it is revealed that Takizawa was among the Investigators Tatara provided to Dr. Kanou for his experiments.

Power and Abilities
Tatara has not revealed the extent of his powers or abilities, primarily acting as a commander to Aogiri's forces. However, he is stated to be a Ghoul of considerable strength and quite proud of his abilities. As the second-in-command of Aogiri, it can be inferred that he is quite powerful.
