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. – user18961 Nov 7 '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).

    There is another theory that it's "Route A", since the anime has some deviation at the beginning of the season. – nhahtdh Mar 27 '15 at 17:51
  • @nhahtdh Interesting. I could see that being a plausible explanation, too. – Killua Mar 27 '15 at 17:53
  • nhahtdh's theory is the one that I have heard. – Brad Whoville Mar 27 '15 at 22:16
