A jutsu was developed by the Uchiha clan in which the user compresses a large amount of chakra built up inside their body and changes it into a dragon-shaped fireball. The user then skillfully manipulates that great fire, and attacks their opponent with it. The flames exude a very high temperature, as they can create an upward movement of air currents which can give rise to thunder clouds. A master of this technique can fire off several flames in succession and anyone caught in the technique could potentially be reduced to ashes. This is a jutsu that was used by Sasuke Uchiha in order to create the thunder clouds needed to perform Kirin.
