First Division

The of the Allied Shinobi Forces, also known as the, is led by Darui.

History
Upon its formation, the First Division is mobilized to the western coast of the Land of Lightning. Because an enemy attack is inevitable, the First Division fortifies the beachhead and stations its forces along the cliffs. A contingent of Zetsu clones and numerous resurrected shinobi soon emerge from the nearby ocean. After the two sides face off, Darui makes the first moves with his Lightning Release: Black Panther, electrocuting dozens of the Zetsus. The rest of the division attacks as well, bombarding the approaching Zetsus with kunai and engaging those that slip past in close combat; Hiashi Hyūga is drawn into combat with his dead brother, Hizashi, and Chōza Akimichi increases his size to combat the likes of Dan and Asuma Sarutobi. Kakuzu goes after several First Division members, whom he preys upon with his Earth Grudge Fear.

Darui confronts the Gold and Silver Brothers, two criminals from Kumogakure's past. Because the brothers wield four of the Treasured Tools of the Sage of the Six Paths, Samui and Atsui provide Darui with backup. Both are quickly trapped in the brothers' Benihisago, but their capture allows Darui to learn how the Treasured Tools work. With this knowledge Darui is able to take the Benihisago and the Shichiseiken from the brothers. He then uses the Benihisago to capture Ginkaku. Kinkaku becomes enraged by this and enters a Nine-Tailed Demon Fox-form. Using the strength and the large tail he gains in this form, Kinkaku storms through the First Division, killing hundreds and destroying much of the battlefield.

When the Fourth Raikage learned of Ginkaku and Kinkaku's presence, he expected trouble and planned ahead. Now that none of the First Division can handle Kinkaku he implements several of the backup plans he prepared for the brothers. He first sends the fifth Treasured Tool, the Kohaku no Jōhei, to Darui to be used to seal Kinkaku. Reinforcements that he summoned from the Second, Fourth, and Fifth Divisions also arrive and quickly join in on the defence against Kinkaku. Formation Ino-Shika-Chō then teams up with Darui and seals Kinkaku into the pot, finally defeating the Gold and Silver Brothers.

Later however, the entire division is decimated when Madara Uchiha arrives with the Summoning: Demonic Statue of the Outer Path and steals the sealed Gold and Silver Brothers for their Nine-Tails chakra
