Fire Release: Rivet

This is a high level Fire Release technique, believed to date back to the age of the Kasai. Rather than kneading Fire Release Chakra in one's stomach, this technique requires the user to gather it in their arm. Once the appropriate hand seals have been made and the chakra has been gathered, the user thrusts their palm outward towards the target, launching the chakra. Upon leaving the user's body, the chakra is converted into fire. The resulting blast of fire is only about the size of the user's first, but leaves a long tail as it speeds towards the target much faster than a standard Fire Release attack. The speedy Fireball is capable of burning a hole clean through a human chest and continuing forward.
