This technique exhales an extended stream of unbelievably hot black fire from the user's mouth, similar in fashion to a flamethrower. The flames are so intense that they can reduce a boulder to a pile of ashes in mere seconds.

Gen Nakaido's version is different than the average. Gen releases a black stream of fire from his mouth that is actually infused with gunpowder to give it its black color. In motion, the powder and fire separated by a thin lining of wind chakra. When it makes an impact with its target, the gunpowder and fire mix together to trigger a massive explosion.

This technique has two major drawbacks. Firstly, it requires massive amounts of chakra to use and as such, only Kage level shinobi can use it without being at risk of severe chakra exhaustion. Secondly, only masters of Fire release can hope to use this technique without injuring, or even killing themselves by burns.
