Tatara

A direct subordinate of the One-Eyed King and one of Aogiri Tree’s leaders who also seems to be from China. He is related to the Chinese ghoul organization Chi She Lian.

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.

As the second-in-command of Aogiri, it can be inferred that he is quite powerful.
