Tatara

I am very happy. Everything ends today. My chagrin toward my older brother, my hatred towards you, and... Aogiri Tree.

Tatara Attakai Kaji is a Fire Spitting Demon and the subordinate of Eto Yoshimura in the Aogiri Tree.

Appearance
Tatara was a tall man with short white hair and red eyes. He hid his mouth with a red iron mask and was seen wearing a white cloak most of the time. When he was first seen with Eto, he was wearing a large blue cloak.

Personality
As one of the Aogiri Tree leaders, 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 who killed 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 seemed to have a taste for precision.

He holds a grudge against Medusa Ryle Vaiself, as she was one of those who killed the members of Chi She Lian, including his brother. Tatara also has an air of royalty around him in the Aogiri Tree, suiting for someone of his rank, complemented by a commanding gait.

Aside from Eto, he considers everyone in Aogiri Tree to be peons.

Demon Lord Arc
Tatara and Eto were watching Justice Hendricks and Hinami Hendricks reunite. Eto claims that Justice has gotten stronger the last time they saw him, which Tatara agrees to. It is unknown when Tatara and Eto last saw him, though.
