Boil Release: Corrosive Mist Technique

The user first must activate the Hiding in Mist Technique then they then disperse their Boil Release chakra throughout the mist, then they are able to control the acidity of the mist via chakra control. Ryū tends to utlilize this technique to change the Ph of the mist to equal that of Fluoroantimonic acid which is a -25 on the Ph scale thus nearly killing anything/anyone within the original Hidden Mist Technique nearly instantly. Ryū is also able to select who exactly the corrosive mist affects as he doesn't wanna hurt any of his comrades.
