Fourth Division

The of the Allied Shinobi Forces. Also known as the.

History
With the separation of the Great Battle Regiment into five distinct detachments, those in the Fourth Division gather together in a linear formation and begin to converse amongst themselves, where Temari discusses the technicalities that have resulted in Shikamaru Nara becoming the company's proxy commander, much to his chagrin. It is only after Gaara concludes his heartfelt speech about how their army is united under the collective term "shinobi", by divulging his history and relationship with Naruto Uzumaki, does the entirety of the Allied Shinobi Forces finally begin to maneuver into their respective positions in preparation for battle.

During this relocation, the Fourth Division eventually divides itself from the main contingent, settling in amongst the rocky and barren terrain near the southern edge of the Land of Lightning's peninsula. By dispersing a significant quantity of sensing sand before his unit, Gaara is able to detect the concealed presence of an unknown assailant, that even the Sensor Division was unaware of. Continuing to observe this individual from afar as he summons three more resurrected shinobi and their latter conversation, the division is informed that their opponents consist of four former Kage - the Second Tsuchikage, the Second Mizukage, the Third Raikage and the Fourth Kazekage.

Informed of Shikaku Nara's revised strategy that takes these recent developments into consideration, by Inoichi Yamanaka's Intelligence Division, it is intended 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 these tatics; Ōnoki arrives in support of the division at Gaara's present location, where upon receiving a remark concerning the potential straining of his back, he retorts that it was Gaara who got him riled up in the first place. Identifying that he is here to regain the principles he tossed aside long ago, the pair await the arrival of the resurrected Kage, with Ōnoki intent on defeating Mū.

Arriving in support of the First Division, Shikamaru and Chōji Akimichi accompanied by a considerable portion of their own unit, combine their efforts in the engagement with separate detachments from both the Second and Fifth Divisions. Upon receiving further instruction from his father, Shikamaru coordinates a formation involving Chōji and Ino Yamanaka, in order to combat a six-tailed Kinkaku. Shikamaru then exploits Chōji's distraction to momentarily bind the desired target, allowing Ino to successful manipulate Kinkaku into uttering the intended response, resulting in his capture within the Kohaku no Jōhei.

Shikamaru and Chōji then turned their attention to their former teacher, Asuma Sarutobi. After an emotional fight which nearly turned deadly due to Chōji's inability to hit their teacher, they managed to defeat him with Formation Ino-Shika-Chō. Chōji, using his Multi-Size Technique in combination with the Butterfly Bullet Bombing continued to fight against enemies in their location. Shikamaru fought Kakuzu. After successfully defeating all enemies on the battlefield, Madara arrived and summoned the Demonic Statue of the Outer Path. Chōji and his father Chōza attack the Statue, but are easily defeated. Shikamaru though realized what the Statue was from intelligence presented by Temari at the Alliance strategy meetings. Shikamaru pursued Madara and pined him. He correctly deduced that Madara's plan was to seal the Nine-Tails' chakra contained in the Gold and Silver Brothers' body. Madara complemented Shikamaru and considered him a worthy adversary, but then has the Statue attempt to step on him. Shikamaru is saved by Chōji.
