Fire Release: Dragon Fire Technique

The user breathes fire along a cord or any other type of long object, which rushes forward in straight line catching the enemy on fire. A line of enemies can be used as the conductor as well. The flames are meant to target, and assault the enemy's upper body just like a projectile weapon.

While the technique is shown in the anime to be even larger and more devastating than Fire Release: Great Fireball Technique (and being able to melt rock), in the manga it is shown to be just a small burst of flame running along a line of wire.

Trivia

 * In the anime and OVA, this technique has been used without a conductor, but the enemy was much closer in both cases.
 * In the second OVA, this technique begins like the anime version of this technique but the blaze splits into multiple smaller dragons of fire that strike the foe from multiple directions.
 * Jiraiya uses this technique in an omake released in the second fanbook, which was later adapted in the anime.
