Koganenohi

This is a unique style of fire that was created by Sumi after studying the unique coloration of the Amaterasu and Black Lightning as well as their mechanics. Unlike the former and the latter, this element's coloration is gold, most likely derived from Sumi's own chakra signature; which sensors have stated to be of a golden hue. These golden flames are said to be significantly hotter than normal fire, as well as denser, having a smothering quality to them instead of pure incineration. They are also noted to be more malleable than normal fire, allowing for the creation of complex constructs that suit Sumi's fighting tendencies. The hotness of this fighting style and its derived techniques are stated to be just below that of Amaterasu, making them a very dangerous fire to behold.
