Who is this Aogiri member (a girl on redhood) in the anime adaptation? I want to ask who she really is. All I know is that she is member of Aogiri.
According to Tokyo Ghoul Wiki, her name is Eto. As a ghoul, she is known as the 


  One-Eyed Owl, 


and her human name is 


  Sen Takatsuki. 


She is also an executive member of the Aogiri Tree.
