This is a special natural energy enhanced genjutsu that Gutaki-Ka created after initially reaching the Sage Mode. The genjutsu starts of with the person intially feeling like he or she is on fire, with the flames licking their way up the person's clothes and body. However, Gutaki-Ka's addition of natural energy "turns up the heat" on the genjutsu, as the fire sinks its way inside, before slowly burning the opponent inside out. It is said that this genjutsu is so potent that the opponent feels feverish and dehydrated, while growing drawn and pale after the genjutsu is dispelled.
