Impure World Reincarnation Allied Forces

Reanimated Allied Shinobi Forces (穢土転生連合軍, Edo Tensei Rengōgun) is a group of reanimation shinobi from various countries, whose mission is to unsealing strong shinobi, previously neutralized by the Allied Shinobi Forces.

Background
When Orochimaru tried to perfect the Summoning: Impure World Reincarnation, he looked for DNA from strong shinobi who had already died in order to resurrect them. He introduced Kabuto Yakushi to this, and he continued to collect material, replenishing the collection not only with good samples, but also with weak shinobi, who more often than usual came across during the experiment. Kabuto decides to keep them all for later use.

Force Composition
The forces consist of the weak, those who died on lower-level missions, shinobi. But among them there are distinctive specimens that are slightly able to withstand the enemy, as well as the only really strong and capable fighter in the person of Torune Aburame. All participants from various countries, including little Kusagakure and Takigakure.


 * Konohagakure Symbol.svg Torune Aburame: leader of Allied Forces, who has summoned everyone else to the battlefield, but whose leadership is contested by other shinobi, despite the fact that Torune does not claim leadership, but simply does what Kabuto indicated. He is the strongest and most dangerous fighter in the team, the last of the entire alliance after a large-scale battle.
 * Land of Fire Symbol.svg Chūkaku: a ninja monk from Fire Temple and a former mentor of Chiriku. He is not a fighter per se, but possesses techniques to remove seals from sealed shinobi. A wise and calm old man who meditates on the sidelines for most of the battle.
 * Sunagakure Symbol.svg Daimaru: an active and daring young shinobi who died on a low-level mission. He is proud and tries to take command by bragging about his nicknames, which he believes everyone should have heard. In its essence, this is partly true and one of the shinobi standing nearby is frightened upon hearing one of his nicknames, but the other shinobi at the same time declares that he is hearing about him for the first time. Daimaru was the penultimate one to be sealed and showed some skill in ninjutsu using the Earth Release.
 * Amegakure Symbol.svg Heiji: calm and quiet shinobi, who during his lifetime was the right hand of Kandachi. He calmly stood on the sidelines for most of the battle and was also the one who discovered the location of Toroi's body. When the odds were tilted towards the enemy, Heiji helped his teammates escape and let himself be sealed without resistance.
 * Kumogakure Symbol.svg Osoi: an active man of age, who during his lifetime was Toroi's partner and died with him on a mission. He fights with the help of a kunai and during the battle he meets his son Musai. They communicate heart to heart and Osoi allows himself to be sealed.
 * Kusagakure Symbol.svg An overweight man from Kusagakure with a beard in light green flack jacket and a large scar running through his right eye.
 * Takigakure Symbol.svg A thin man from Takigakure with a large lightning-shaped scar running through his nose and deep wrinkles under his eyes, wearing a dark gray flack jacket.

Fourth Shinobi World War: Confrontation
After most of Kabuto's trump cards have been sealed, he decides to use all the failed experiments to unseal such needed shinobi as Toroi. Relying on quantity over quality, Kabuto unleashes Reanimated Alliance on the battlefield.

The group immediately begins to protest against the leadership of other people, as Daimaru did not want to obey Torune's orders, but other shinobi did not want to obey Daimaru's own orders. However, the most prominent fighters were able to take control of the matter and sent an army to retrieve Toroi's body, which was guarded by the Allied Shinobi Forces led by Musai.

The dead fighters attack and the defenders of the body, including Nonota, are frightened and panicked at first, but after the first counterattack, they realize that there is a horde of weaklings in front of them and confidently suppress their invasion. During the battle, in different centers there are people from the opposing groups who were familiar during their lifetime. Someone asks for forgiveness from a friend, someone is interested in how his family is,and Musai meets his father Osoi and talks heart to heart with him.

After most of the reanimated shinobi were sealed, Heiji uses a Winding Smoke Technique and allows some of the warriors to leave the battlefield, but he himself was surrounded and sealed. The most powerful fighters, led by Torune, are sent in search of the body of the Third Raikage. At the same time, Temari's team, descending in the other direction, was called back to protect the body.

Team Torune reaches the target and one of the group tries to remove the seal from the Raikage's body, but falls into a trap and was sealed himself. The trap is exposed and Daimaru, using Earth Release: Sand Dance, shakes the ground, removes the sealing seals. Chūkaku throws his prayer beads on the Raikage's body, and begins to make movements with his hands, removing the seal. At this time, Temari's team arrives and she attacks Chūkaku, interrupting the ritual, after which he is sealed.

Daimaru recognizes Temari - they were childhood friends. Deciding that he has nothing to lose, Daimaru confesses his love to Temari, but she rejects his feelings, but thanks that he was the only one who was not afraid to communicate with her because she is the daughter of the Kazekage. Daimaru accepts this and says goodbye to the girl, allowing himself to be sealed. Torune is left alone and escapes.

After escaping, Torune finds a place far enough to execute a unique kinjutsu to his abilities. However, Shino is able to find him with his kikaichū. Notified from Torune's position, Shino starts a battle in order to stop Torune's kinjutsu. Once face to face with him, Torune asks if Shino made any friends, thinking back about their shared past. When they were little, Shibi was Torune's guardian after Shikuro died, leaving Torune and Shino growing to act as siblings. Torune showed him his insects, and saved him from going to the Root by volunteering himself. Torune explains that he never thought he would get a friend like he did in the Root, Fū Yamanaka. In the battle, Torune takes advantage from his taijutsu learned at Root, unleashing an accurate kick to Shino's stomach.

One of Naruto's clones appears and saves Shino from falling into Torune's kinjutsu. Shino shares his knowledge about the opponent's abilities, warning Naruto to not touch Torune's skin, thinking that as the only way his insects could spread their poison. Torune uses his Poison Cloud Technique to attack them from a distance, but it is blocked by Shino's insects. With the warning to not touch Torune's skin, Naruto starts fighting the reincarnated opponent, who tries to use kenjutsu against him, though Naruto succeeds in breaking his sword. Naruto manages to land a Rasengan, and Torune almost lands a punch on him, failing due to Shino putting himself in between them, taking the hit. Torune is confused that Shino isn't suffering the effects of his rinkaichū, and Shino reveals that his punch hit Shino's insects, which Shino has bred with Torune's own insects after he was recruited into Root. This allowed them to build up a resistance against their venom. Shino uses these insects to paralyse Torune, and applies a sealing tag, stopping him and his kinjutsu.

Fourth Shinobi World War: Climax
Later, when the Impure World Reincarnation Technique was cancelled, soul's of all shinobi returned to the afterlife.

Trivia

 * Despite the fact that all reincarnated shinobi are declared as a failed experiment and, as can be seen, very weak, they all, including Daimaru and Heiji, wear vests that are allowed to be worn only after reaching the rank of chunin.
 * Some members of the alliance had clothes of one country, but at the same time they wore a bandana with the emblem of another country. For example, a fat man in a Kumogakure outfit who had the Amegakure symbol on his bandana.
