Pain's Assault

The Invasion of Pain was the attack on Konohagakure by the Akatsuki leader, Pain, in search of Naruto Uzumaki, the container of the Nine-Tailed Demon Fox.

Background
Pain had been instructed by his benefactor, Madara Uchiha, to capture Naruto. When Jiraiya infiltrated his village, Amegakure, Pain was forced to deal with him before he could go after Naruto. Although he was able to kill Jiraiya, Pain had lost one of his six bodies and had to find a replacement before he could move on to Konoha. Furthermore, one of Jiraiya's toads had managed to escape with knowledge of him.

With the information gathered from the toad, the body Jiraiya had defeated, a prisoner he had captured, and a coded message he had made before his death, Konoha had ample sources of information concerning Pain. While some of Konoha's forces dedicated their time to deciphering what Jiraiya had left to them, the rest of the villagers prepared for Pain's arrival. The defensive measures that had been erected since the last time the village was attacked were presumably built upon, and many of the Konoha ninja were kept home. Konoha still took part in its ninja mission business, Team Guy, Hisashi Hyuga and Hanabi Hyuga being away when the attack begins.

Naruto, knowing that Pain would be coming for him, decided to make use of the time Jiraiya had bought for him. He went to Myobokuzan, the home of the toads, to learn senjutsu for his inevitable encounter with Pain. Kosuke was left in Konoha to send word to Naruto when Pain eventually arrived.

Attack
Pain and his partner, Konan, arrived on the outskirts of Konoha and eliminated all of the village's scouts. As the village was surrounded by a detection barrier, Pain's Animal Path was sent in to the village alone to fool the Barrier Team, leading Konoha to believe there was only one invader. After infiltrating the village the Animal Path summoned Konan and Pain's other five bodies to its location, where they dispersed.

The Animal Path, the Asura Path, and the Preta Path acted as diversions; the Animal Path summoned a variety of creatures to draw Konoha's attention, the Asura Path used its many weapons to wreck havoc and destroy the village, and the Preta Path engaged whatever forces it came upon. Konan, the Deva Path, the Human Path, and the Naraka Path dedicated their efforts to finding Naruto; the Human Path reading the villagers' minds, the Naraka Path asking what those he encountered knew and then using its abilities to see who was lying, and Konan and the Deva Path using the threat of death to find out what they wanted.

In the initial phase of the attack, Konoha mobilized its forces expecting only one intruder. Once it became apparent that there was more than one attacker the village switched tactics, focusing in on the diversionary Paths. The ordinary citizens and those that had been injured in the initial wave fled to the Konoha hospital, where Sakura Haruno provided defense and healed what injuries she could. Tsunade, the Fifth Hokage, instructed Kosuke to call back Naruto, but Danzo, having other plans, killed Kosuke to keep Naruto from returning. From the roof of the Hokage Residence Tsunade summoned Katsuyu, who she then had divide, seek out, and adhere to every villager so that she could tend to the entire village remotely.

Kakashi Hatake, recognizing Pain's plan, engaged the Deva Path in battle. The Asura Path came to the Deva Path's defense and, although Kakashi was able to defeat it, he could not defeat the Deva Path as well. He had Choji Akimichi, who he had fought beside, take knowledge of the Deva Path's abilities to Tsunade while he bought time. Kakashi was quickly defeated, but Choji was able to inform Tsunade of what they had learned.

Across the village Konan and Pain's remaining bodies began attracting the attention of Konoha's defenders. Found out, the Animal and Preta Paths switched objectives; the Animal Path assaulted the location where Jiraiya's prisoner was being held and tried to eliminate all present, and the Preta Path found and disposed of the body (and its chakra receivers) that Jiraiya had captured. The Deva Path located and spoke with Tsunade, but became irritated by her words. When the Human Path captured Shizune, Pain was able to discover where Naruto was.

The immediate objective complete, the Deva Path had Konan and the remaining Paths evacuate while it used a large scaled Shinra Tensei to destroy the village and teach Tsunade true pain.. In the brief moment in time between when the destruction began and when it was completed, Tsunade had the remaining Katsuyu copies shield the hospital and dedicated what was left of her chakra to keeping the villagers safe. In the wake of the destruction, all that remained of Konoha was a large crater, the Hokage Monument, and huge amounts of debris, ruins, and half-destroyed infrastructure.

Counterattack
Shima, having been near Konoha at the time, had earlier noticed something was wrong. In unison with the village's destruction, she summoned Naruto, Gamabunta, Gamaken, Gamahiro, Gamakichi, and Fukasaku to the village's center. When the dust cleared Pain and his six bodies (the Asura Path having been restored by the Naraka Path), faced Naruto. Taking the village's destruction personally, Naruto instructed the rest of the villagers not to interfere with their fight.

With the Deva Path momentarily unable to do anything because of its destruction of Konoha, Naruto was able to use his new senjutsu techniques to defeat the other five bodies. Before he could finish off the Deva Path its powers returned. It got rid of Naruto's toad allies and captured him, rendering him immobile with its Chakra Disruption Blades. Defying Naruto's orders, Hinata Hyuga comes to his aid. When she is struck down and appears to be killed, Naruto, in anger, advances to a six-tailed demon fox form.

With the transformation, Naruto gives in to the demon fox's animalistic instincts in return for power. He is able to free himself and tries to attack the Deva Path with a Six-Tailed Fox Menacing Ball. Pain diverts the attack at the last minute and it goes astray, punching a hole through the rubble of the village. Recognizing the danger of Naruto's new form, the Deva Path retreats to a location closer to Konan and Nagato, Pain's base mind. Naruto pursues him, finally giving the village a chance to regroup and tend to the wounded. There, Deva Path uses Chibaku Tensei and almost captures Naruto as he goes into eight-tailed demon fox form to counter him.

After some soul searching, Naruto turns back and Naruto and Pain prepared for what they knew to be their final battle. The two continue to talk about their ideals and as Naruto fires a Rasenshuriken, Deva Pain deflects it. However, Deva Pain realizes that there was a second one that Naruto knew would hit during the 5 second interval. Pain managed to dodge it, but Naruto then sends multiple Shadow Clones to attack Pain. Pain deflected those as well, but during his new five second interval Naruto managed to hit him point blank with a Rasengan.

With the last body of Pain destroyed, Naruto advances to the location of Nagato, which he had discovered during his fight with the Deva Path. On the way he ran into a team including Shikaku Nara and Inoichi Yamanaka. Inochi, after discovering Naruto's plans to face Nagato alone, wished to assist Naruto. However Shikaku, realizing Naruto must have a plan, told Inochi to let him go. Naruto quickly reached Nagato and Konan's location, and enters. Upon his entrance Nagato states simply that "Peace has arrived". Nagato then shoots a black rod from his chair, and it pierces Naruto through the stomach. He says that from that close, he could control him easily. Naruto's eyes turn Kyuubi-Sage mode eyes, and he pulls out the black rod. Konan and Nagato are shocked. Naruto says he wanted to kill Nagato so badly, he was shaking. He then runs up, getting ready to punch Nagato. Konan jumps in front, but then Naruto stops. Naruto and Nagato then have that long-awaited conversation. Naruto asks Nagato if he was Jiraiya's apprentice, why did he turn out like that? Nagato tells him he had 2 great sources of pain, one being the death of his parents. During the third great shinobi war, Amegakure was used as a battlefield. Konoha ninja entered his house, and they killed his parents. Realizing Nagato's parents weren't ninja, they apologized to him. Nagato's rinnegan was then activated.
