Fire Release: Daybreak

This technique is simply a sudden burst of heat itself, with no initial flames produced at all. The user will concentrate their chakra into a single shockwave, which will travel outwards in every direction, roasting everything in it's path, or causing things to spontaneously combust upon contact. The heat wave is hot enough to practically cook a human alive if a direct hit were to occur, which would be difficult to prevent due to the high speed at which the technique travels. The wave travels on until it simply runs out of "fuel", greatly scarring the surrounding landscape.
