@TU3, chapter 464 confirmed Blaze Release: Kagutsuchi and Amaterasu to be the same thing (per Kankuro's statement). It was also confirmed that Blaze Release is the release of black flames (per Gaara's statement) in the same chapter. And plus, what Tau said about Kagutsuchi and "Enton" being omitted from it in the battle vs Kaguya. The third databook has Amaterasu as Fire Release. The fourth databook has Kagutsuchi as Fire Release. Manga had them as Blaze. Either Amaterasu and Kagutsuchi are both Fire or Blaze.
