Fire Release: Intelligent Hard Work

Kakuzu's fire-element mask spits out a small fireball that erupts into a giant firestorm after making contact with a surface, causing widespread destruction to the area. Since the flames travel along the ground, and from such a wide area this is a difficult technique to evade. The effect of this technique can be increased greatly by combining it with a Wind Release technique like Wind Release: Pressure Damage.

Trivia
