The Eye of the Moon Plan (月の眼計画, Tsuki no Me Keikaku) is Madara Uchiha's ultimate plan to create an idealistic world, which was later adopted by Obito Uchiha. With the Allied Shinobi Forces seeing this as nothing more than robbing humanity of their free will, they intend to foil this plan. This led to the declaration of the Fourth Shinobi World War.
Madara created the plan by studying his distant ancestor, the Sage of the Six Paths. He resolved to gather the nine tailed beasts and merge them with the Demonic Statue of the Outer Path in order to revive the Ten-Tails. Then, he would become its jinchūriki and use its god-like power to reflect his Mangekyō Sharingan on to the moon, which had previously served as a container for the Ten-Tails' body, and shroud the world in an "Infinite Tsukuyomi" (無限月読, Mugen Tsukuyomi). This scheme would result in Madara's ability to manipulate every living creature, ceasing all conflict by purging free will itself from the world.
Due to his poor health and old age, Madara could no longer work on the plan at some point, and left its completion and his will to Obito Uchiha, who had came to believe that the "dream world" would bring back his beloved Rin Nohara. Obito would then join and take control of the Akatsuki after Yahiko's death, though most of its members were unaware of the organisation's true objectives. Posing as Madara, Obito ensured that Nagato, the figurehead of Akatsuki, would revive Madara with the Outer Path: Samsara of Heavenly Life Technique when the plan finally came to fruition at the cost of the latter's life. Nagato told the akastuki members that they were gathering the tailed beasts in order to maintain a monopoly on war, even though Nagato and Konan knew of Obito's moon's eye plan, as when Konan was fighting Obito, Obito asked why her and nagato would betray him, despite approving of the moon's eye plan. Obito's personal ambition for the Eye of the Moon Plan is to remove the agency of all living creatures and create a reality where Rin is alive so they can be together once more. He had also approached Kisame Hoshigaki, requesting his participation in the cabal with the offer of liberating him from the "world of lies"; Kisame, having lived a life tainted with deception and betrayal, gladly accepted to the "world of truth" he desired, and along with Obito and Zetsu, became one of the only Akatsuki members to know the truth of the organisation's ambition.
Progress of the Plan
Though Obito obtained seven of the nine tailed beasts, only the final two tailed beasts: the Eight and Nine-Tails, remained out of his grasp. After Nagato's death ruined any chance of Madara's resurrection, Sasuke Uchiha's failed attempt to capture Killer B provided him with a fragment of the Eight-Tails' power. Obito decides to take Madara's place in the Eye of the Moon Plan. Discarding all caution and revealing himself, Obito arranged to place Sasuke and his team at the Kage Summit in hopes the ninja leaders would be weakened enough to be easily taken hostage to negotiate their freedom in exchange for the last two living jinchūriki, Killer B and Naruto Uzumaki. This, however, ended in failure, due to Danzō Shimura escaping during the chaos while combined forces of the Kage, their bodyguards, and Mifune overwhelmed Sasuke. Sending Sasuke into the other dimension with Karin, Obito introduces himself as Madara while revealing this plan to the four Kage. However, they refuse to hand over Killer B and Naruto while forming the Allied Shinobi Forces to prevent Obito from going through with his Eye of the Moon Plan.
At the end of the first day of the Fourth Shinobi World War, Obito took the Kohaku no Jōhei and Benihisago that each contained one of the Gold and Silver Brothers, and having already fed the Eight-Tails' tentacle to the Demonic Statue, intended to put the plan into motion by the end of the following day. Madara's return through Kabuto Yakushi's Impure World Reincarnation ruined Obito's ruse, and when fighting Naruto his mask was shattered, revealing his true identity. Obito fed the Kohaku no Jōhei and Benihisago to the Demonic Statue in order to revive an incomplete Ten-Tails, claiming that the monster would still have enough power to be sufficient in completing his plan. Once joined by Madara after he defeated the Kage, Obito is scolded for deviating from the original plan due to the Ten-Tails' revival being incomplete and his own revival through a different method. Regardless, entrusting Obito to make sure no one interferes as he battles Naruto and Killer B, Madara decides to capture the Eight and Nine-Tails personally to complete the plan while there is still time. Though Naruto and Killer B made an attempt to destroy the Demonic Statue with a giant Tailed Beast Ball, they were unable to stop the Ten-Tails's revival.
Though he attempts to control the Ten-Tails by having himself and Obito use Hashirama's DNA, Madara begins to see that the monster is beginning to resist control. Because he was revived by Impure World Reincarnation, Madara is only an reanimated corpse and cannot become the Ten-Tails's jinchūriki, which would require him to be brought back as a living body with Samsara of Heavenly Life Technique that only Obito, having obtained his master's Rinnegan, could now execute. However, using that fact as leverage since using the technique would kill him, Obito persuades Madara into letting him use the Ten-Tails to instil despair on Naruto and the entire Allied Shinobi Forces.
- Obito has blamed Naruto for the plan's slow progress, due to his constant interference causing him to deviate from the plan as Madara envisioned, despite the plan would eventually involve capturing Naruto.
- Obito noted that he would eventually synchronise Sasuke Uchiha with the statue.
