Didn't necessarily specify that Katon and Enton are "completely different." Kankourou did equate the black flames to Amaterasu in chp. 464, which is correct. Gaara mentioned the black flames but didn't associate it with either Amaterasu or Blaze Release. WindStar7125 I think you over-interpreted chp. 464.

I still failed to see how Amaterasu = Blaze Release. Amaterasu is a technique that casts the black flames (as stated in 2nd and 3rd DB, and shown several times in the manga) and the name "Blaze Release" debuted as part of the name of Sasuke's technique that controls and reshapes black flames.
