A powerful wind technique released by Kakuzu's wind-element mask. This tornado-like mass is compressed until it has a very high density before being released. The blast can hit a vast range, inflicting massive damage on both the target and their close surroundings. This technique can also be combined with the Fire Release: Intelligent Hard Work, to increase the flame's potency in a great scale, causing a massive fire-storm.
Like the rest of Kakuzu's techniques, the name of this technique comes from the mecha anime Mobile Suit Gundam (機動戦士ガンダム, Kidō Senshi Gandamu). The name Atsugai was taken from the Gundam MSM-04 Acguy (アッガイ, Aggai). The name was altered slightly and given kanji to create the name of this technique.
