As the title says, why is Tokyo Ghoul's second season called √A?

  • Probably standing for Root A. "A" standing for Aogiri and "Root" for the root of a tree. –  Nov 07 '15 at 20:10

√A ("root A") is a reference to and pun on the Aogiri Tree organization, which is the focus of the second season. "A" is simply the first letter of the organization, and the root is a pun on tree root (since it's the Aogiri Tree).
