Fourth Division

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

History
Upon its formation, the Fourth Division is mobilised to the rocky and barren terrain near the southern edge of the Land of Lightning. Gaara scatters a significant quantity of sensing sand in front of his unit which allowed him to detect an approaching, revived Mū, the Second Tsuchikage. He later uses his Third Eye to observe the opposition, only to see him summon the Second Mizukage, the Third Raikage and his father, the Fourth Kazekage.

Knowing four Kage will be difficult to defeat, headquarters dispatches Ōnoki to provide assistance, in particular regards to countering the threat posed by Mū's techniques. Headquarters also restructures the Fourth Division to prepare for the inevitable encounter with the Kage, while accounting for the other concurrent battles taking place. These orders dictate that the Fourth Division will start to retreat while forming into a sideways chevron (">") formation. They are then expected to keep the opposition at bay, until the top part of their arrangement can break away and provide assistance to the overwhelmed First Division, with them only returning accompanied by further aid once these enemies are defeated.

Acting in accordance with this strategy, Shikamaru Nara successfully leads part of their forces to the First Division, leaving the remainder of the division to continue their withdrawal and await the Kage's response. Immediately upon their arrival, these vital reinforcements are instrumental in sealing the rampaging Kinkaku, with Shikamaru adhering to his father's instructions by collaborating with both Chōji Akimichi and the Fifth Division's Ino Yamanaka in order to accomplish this deed. Continuing the confrontation, the subsection of the Fourth Division is split amongst numerous distinctive assignments occurring throughout the battlefield, with the current generation Ino-Shika-Chō employed once again in the intention of them defeating their deceased mentor, Asuma Sarutobi. Despite encountering difficulties in completing such an arduous task, due in part to their reluctance of opposing a former comrade, a freshly resolved Chōji eventually manages to immobilise Asuma and then in an attempt to conclude the battle, sorties to the other areas in need of assistance. Annihilating the remaining opposition, relief momentarily embraces the battlefield, until Madara Uchiha summons the Demonic Statue of the Outer Path and commands it to attack. Sustaining considerable casualties throughout the duration of the confrontation and in the wake of the enormous creature, the judgment is made to attend to the wounded during the night, before proceeding to converge with the rest of the Fourth Division the following day.

Relentlessly pursued by the resurrected Kage throughout the entire night and unable to maintain such a stance for much longer, Gaara and Ōnoki decide that it was now time to go on the offensive, if only just to observe their adversaries' reaction. Unleashing a colossal wave of sand with the intention of restraining and then obliterating the opposition in the ensuing chaos, both of the attacks prove ineffective in the face of the Fourth Kazekage's Gold Dust and Mū's counter respectively.
