Fire Release: Great Fire Destruction

A technique where chakra kneaded inside the user's body is converted into fire, and then expelled from the mouth in a massive stream of intense flames that can set a vast area ablaze, engulfing the target in a veritable sea of flames. If used upon dense, combustible terrain such as a forest, the confined area can greatly increase the possibility of the target's incineration.
