Fire Release: Intelligent Hard Work

Kakuzu's fire-element mask fires a small fireball that erupts into a giant fire-storm after making contact with a surface, causing widespread destruction to the area. Since the flames travel along the ground, and cover such a wide area this is a difficult technique to evade, and it can end up hurting both the user and the opponent on contact.. When combined with Wind Release: Pressure Damage, this technique is amplified to the point of being able to evaporate a large amount of water in an instant.

Trivia

 * Like the rest of Kakuzu's techniques, the name of this technique comes from the legendary mecha anime . The name Zukokku was taken from the Gundam MSM-07 . The name was altered slightly and given kanji to create the name of this technique.
