Apparently, the author has different ideas... if the information released so far is of any indication, then Blaze Release is Fire+Yin. I wonder what sense does it even make to have a nature that isn't a merger of two elemental ones. Fire+Yin does nothing but opens the can of worms for Wind/Lightning/Earth/Water+Yin and possibly Fire/Wind/Lightning/Earth/Water+Yang, hell even an element mixed with Yin-Yang by the titans.

And here we are left with Fire+Lightning, Wind+Lightning, Wind+Earth, Lighting+Earth left unrevealed and several advanced natures' compositions left unanswered, with a databook released after 6 years and 2 manga chapters left to go... I'm disappointed. That would've worked out nicely, and ESPECIALLY considering that the Uchiha have that connection with cats, having Matatabi be the Enton holder would've came together quite nicely. If I recall correctly Amaterasu is supposed to burn chakra too, or something to that effect. Having Enton and Matatabi's flames be flames that can burn ethereal things as well would've been a nice touch and a good anti-Biju anti-Susano'o weapon. So your Sharingan genjutsu (Tsukiyomi) beats Amaterasu by knocking them out before they can launch it, Amaterasu beats Susano'o by burning it down, and Susano'o beats Tsukiyomi by blocking it (As Sasuke did the Infinite version). It works perfectly.

However...does this mean that Kokuo and Saiken share an element? Boil Release has corrosive properties in Mei and presumably Saiken, but steam power in Kokuo.
