Tatara

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

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

Appearance
Tatara is a tall man with short white hair and red 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 blue cloak.

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.

He has also been noted by Ayato Kirishima to consider his underlings to be mere peons, something he willingly confirms.

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 11th Ward Base to Noro. Tatara predicts that the doves would come soon and told Noro to follow their plan.

While the 11th Ward Battle is taking place Tatara and Eto lead many of Aogiri's stronger members in an attack on Cochlea, freeing multiple dangerous ghouls.

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
Nearing the end of the Anteiku raid operation, Tatara is seen attacking the reinforcements brought by Seidou, 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".

Auction
He leads the Aogiri Tree attack on the Quinque Steel Transport and is seen ordering a retreat when the attack fails

Rosewald Investigation
After all of the Aogiri Members escape from the Auction Hall following the raid, Tatara is seen in the greenhouse during an important meeting where Ayato is trying to convince him to attack Cochlea and rescue Hinami. Tatara rejects the claim and Takizawa starts laughing at Ayato for having an affection for her and then stated that he fought her. Ayato gets furious and then Tatara grabs him and prevents him from starting a fight. Tatara then berates Ayato for his actions while Seidou continues to laugh in the corner.

Fei and Yan
Tatara was close to them when he was younger and a member of Chi She Lian. Their deaths are possibly the reason why he hates Kousuke Houji so much that he easily loses his nearly unflappable composure upon encountering even a quinque associated with the ghoul investigator.

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.

Yakumo Oomori
Tatara doesn't care what Yamori's activities are, showing no sadness at the news of his death reaching him.

Bin Brothers
Tatara doesn't seem to have any concern for them, shown when he answers yes to Ayato's question about his considering subordinates to be mere pieces to him.

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.

Matasaka Kamishiro
Tatara appears to think of Shachi as a soft person, as implied when berating Ayato after the Auction Raid as growing soft due to Shachi's influences.

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. He is seemingly able wipe out a squad led by Associate Special Class Mutsumi Chino with ease. He is also extremely fast, able to seemingly teleport to Seidou's position and strangle him.

In Tokyo Ghoul √A, his kagune can been seen for a brief moment before his confrontation with Seidou Takizawa, but the exact RC type is still unknown. Its appearance and basic location suggests that it is either a Rinkaku or a Bikaku, but it has not been confirmed which it is. √A Also suggests that Tatara has a strong resilience and regeneration as he is able to take a hit from Special Class Misaka's quinque without any visible wounds in the time it takes him to break out of its grip. He also seems to endure Houji's Hollow without sustaining major wounds.
