Minato Grunted as he pumped chakra into the seal containing Kurama.
"Suck it up boy, you're not the one giving birth. A man couldn't survive this kind of pain." Biwako said to the Hokage.
"Minato sensei we've got a problem!" Kakashi yelled through the open window.
"What's going on?" Minato asked his student.
"We're under attack, whoever they are they brought an army." Kakashi yelled as something hit him slamming him into the wall.
"Peace was just declared earlier today, the war is over! Whoever it is isn't going to have a village by the end of this!" It is very hard to anger the Yondaime Hokage, but this did the job. "Sensei, take care of thing here for a minute. I'll be back in a flash." Minato said to Jiraiya before he teleported away.
The scene outside was hectic to say the least. It smelled like a graveyard, and an army of white humanoid creatures with green hair were attacking Konoha. Their main target seemed to be the cabin that Kushina was giving birth in though, which made almost didn't make sense, unless they were after Kurama.
Minato pieced their goal together in seconds, he then returned to his wife. When he entered the cabin what he found was enough to drive any mad over the edge. One of the creatures had his son. This one was slightly different though. Its left half was completely pitch black, it had two large plant like protrusions coming from its shoulders, and it had a pair of Sharingan eyes.
"Move at all and this infant dies." It said holding.
Kushina started screaming as Kurama was ripped from her stomach. "No! Not again! I refuse to let those eyes control me again!" Kurama yelled as he was being pulled from his container.
Outside was a complete warzone, Nagato, Yahiko, Konan, Rin, and Obito were tearing through enemies left and right. Nagato was in his Asura form, Yahiko was in his mutated sage form, while Rin was in her version 2 cloak with two tails out. Each of the attacking creatures was weak enough for a skilled Genin to take down with relative ease, the problem was their numbers. There were a few thousand of these things, the entirety of Konoha's Shinobi Corps was having trouble keeping them out of the village. Some managed to make through a hole in the wall that some had made via self-detonation. Those that made it in however were swiftly dealt with by the Uchiha Military Police. Just when things seemed under control all of the creatures stopped in their tracks and began retreating. The reason became clear a moment later when a worse than worst case scenario for those who knew about Kushina's burden came true. Not only was Kurama out, but his eyes shown the Sharingan, meaning that he was possessed by someone with a Sharingan.
With the front line fighters
"Guys! Minato sensei told me to have Nagato, and Rin hold the Kyubi back for a little while. He's preparing to re-seal it and needs time! Yahiko, Obito, and Konan you three are with me. We have to fight the one controlling the Kyubi." Kakashi shouted as he landed between Obito and Rin.
"Isobu, let's go!" Rin yelled before transforming into the Sanbi, prepared to square off with Kurama.
"Kuchiyose no Jutsu!" Nagato shouted summoning his twin headed dog along with the giant drill-beaked bird.
Meanwhile Kakashi led the others back to the cabin that was now a pile of rubble. "Our target was last sighted here. Do any of you have any tracking skills?" Kakashi was all business when he spoke.
"I can see some residual chakra signatures, one of them belongs to Kushina-san, another to Sensei, the other is unknown." Obito said looking closely with his Sharingan.
"Where does it go?" Kakashi asked.
"Into the ground deeper than I can see, let's see it I can fix that." Obito said before making a few hand signs and performing the Moguragakure no Jutsu. He shot into the ground searching franticly for their target.
A few moments later Obito resurfaced dragging out the half black creature that possesses the Sharingan. The creature immediately went on the offensive firing off a Hōsenka no Jutsu, only for it to be countered by Yahiko's Sōkai Enpō (Twin Mystic Flame Cannons). Next it attempted to flee underground before it had its chest pierced where it's heart would've been y Kakashi's tanto. Konan then proceeded to coat the creature with paper after Kakashi pulled his tanto out. Konan threw it into the air before Yahiko sliced it into four pieces using claws that merged to form a blade like structure on the end of his hand as he shouted "Kaishu Jinsō!"(Blade Nails of the Mysterious Hand). The fight was far from over though since the black half attached to another one of the creatures transferring the Sharingan along with the plant like protrusions.
Back with the Biju/summon fight.
"Rin I don't know how long we can keep this up! Kurama was always the strongest of my siblings, we're lucky to have trapped him for this long!" Isobu shouted inside Rin's mind.
"Just a little longer!" Rin replied as Kurama smashed through the Coral Dome that previously trapped him with a Bijudama. Rin, and Isobu took the brunt of the blast that made it passed the Coral Dome, redirecting most of the blast away from the village. The small portion of the blast that did make it through blew an entire sector of the village away though.
Nagato's dog summon which had to this point been split into twenty different beasts attacked Kurama from behind, two latched onto each tail, while one grabbed his neck, the other grabbed his leg, dragging the Biju to the ground. Rin and Isobu then jumped on top of Kurama holding him down for the time being.
Back with Kakashi and the others.
"This is getting us nowhere fast! We need to destroy its eyes, or put it under an even stronger Genjutsu than it's using in the Kyubi." Obito yelled at his comrades trying to formulate a plan.
"What about breaking its concentration, can that work?" Konan asked the younger boy.
"No, it's using an Uchiha hidden Genjutsu, one that requires the Sharingan, it will stay until either the Sharingan that applied it is destroyed, the user is killed, or the user releases it. If I can overpower his Sharingan then I can force this thing to release it, but it has a fully matured Sharingan while mine is only fully matured in one eye. I can try, but it needs to stay still long enough for me to make direct eye contact for a few seconds." Obito responded.
Having heard this Yahiko, Konan, and Kakashi sprang into action. Yahiko went for a frontal assault hoping to distract the creature with a flurry of punched and kicks. Konan took the opportunity to wrap it in a foot of chakra enhanced paper before Kakashi shouted "Tajū Doryūheki!" causing two walls of dirt to pop out of the ground before they converged upon the target effectively binding it in place.
"Now Obito!" The other three shouted in unison
Upon hearing this hearing this Obito shunshined in front of the enemy looking deep into its eyes. As the two sets of Sharingan met they began spinning. A few moments later Obito screamed in pain before gripping his eyes which were bleeding profusely. "MY EYES!" He screamed as he fell to the ground writhing in pain.
"Obito!" Kakashi yelled before Konan leapt to his side and began using her paper to bandage his eyes.
"That boy has much potential, to be able to disrupt a Genjutsu cast by the eyes of Madara Uchiha is no small feat. It's almost a shame that his eyes are probably destroyed after tonight." The creature spoke in an inhuman voice that sounded like a mashup of four or five different voices.
"It talks!" Yahiko yelled in surprise since none of the shinobi present had heard their foe talk and didn't know that it had the capacity to do so.
"Yes I do. It seems my mission was a failure, so until next time young ones. I do hope you get stronger before we meet again, this was barely a warm-up. For future reference you may call my brethren and I Zetsu." The creature now identified as a Zetsu said before it tore through the paper and walls of dirt with what appeared to be tree roots. This took the shinobi by surprise, this thing just used Mokuton.
Back to the Battle of the giants
The Sharingan in Kurama's eyes faded before his consciousness began to follow. Before he passed out he managed to say "Bring Kushina here. If I can get back into her seal swiftly enough it may save her life."
"Rin can you and Isobu Carry him?" Nagato asked.
"For a short distance. That fight took a lot out of the big guy and me." Rin said as she and Isobu picked up Kurama's unconscious body.
Nagato began flying in the direction that he sensed Kushina and Minato. His expression suddenly became one ok shock as Kushina's chakra signature started getting weaker by the second. "Hurry, Nee-chan's dying!" Nagato shouted as they picked up the pace.
They arrived at the same time as the Zetsu suppression team only to see a horrific sight. A Zetsu whose body liked as if it were made of twisted roots decapitating Kushina. It turned to face them and began to speak in a goofy voice. "Hello there. Can you people satisfy my curiosity? I want to know what it's like to be human, and one question keeps coming up. How does it feel to poop?" It had to dodge an onslaught of attacks made by several enraged shinobi. It began mumbling about something as it fazed into the ground. Retreating it said "Maybe next time then?"
"NEE-CHAN!" Nagato screamed as he ran to her corpse cryng. He quickly activated the Powers of the Naraka Path, summoning the head of the King of Hell. It took Kushina's body, and her severed head into its mouth and chewed them a few times before it spat them back out attached to one another, her body was good as new even though she was still dead. Nagato then picked up her body and held it close as he cried out.
The shinobi present looked around for a second unsure of how to comfort their comrade before they seen the Shinigami appear next to Minato before it grabbed Kurama and began cramming it into his newborn son. They rushed to the now dying Hokage, except Obito who couldn't see to make it all the way there and tripped over a candle at the alter that a newborn child was laying on. The infant began crying alerting the shinobi to his presence.
"Bring me my son." Minato said weakly, it was clear that he only had a few minutes to live if he was lucky. Kakashi quickly fetched the infant and Obito and brought them to Minato. "Thank you." Minato said as he removed his coat and began swaddling his son with it. "I'm sorry Naruto, for not being there, for your burden, and for not being able to save your mother. I Hope that one day you'll understand, and maybe you'll be kind enough to forgive this fool for the problems that he's caused you." Naruto stopped crying and fell asleep in his father's arms.
"Kakashi, Obito, Rin, I'm proud of you three. You've all grown into fine shinobi, and I'm glad to have been your sensei. Kakashi, you've learned the importance of your comrades, and what it truly means to be a shinobi. Obito, you don't let anything stop you from achieving your goals, maybe one day you'll become a fine Hokage. Rin, even after having a Biju forced into you you're still training to become a greater medic than Tsunade, I'm sure you will soon enough. Nagato, Yahiko, Konan, You three are some of the greatest people, and shinobi that I know. Don't let this night stop you from becoming even greater people, or shinobi." Minato said, his voice was getting weaker by the second.
"What happened here Minato?" Hiruzen Sarutobi asked as he landed next to the group.
"I'm sorry, I don't have time to explain. I have two more orders as Hokage to give, first Hiruzen I'm sorry that I have to do this to you, but you have to take the seat of Hokage back until someone else is ready to take it up, and my last order goes out to everyone present, please look after my son. Make sure he grows up knowing love, that he knows that I didn't want things to turn out this way, and protect him from those who would seek to end him for being my son. This child, my child, holds a burden greater than the Kyubi on his shoulders. The Shinigami has shown me this. He is…" Minato Namikaze, the Yondaime Hokage wasn't able to finish his sentence before succumbing to the Shinigami's pull. Naruto woke up and began crying even louder than ever. That's when a very small version of Kurama jumped out of the infant's stomach and grabbed him with his tails, he then proceeded to rock the baby asleep.
"What the hell are you doing?" Kakashi asked.
"I heard Kushina's last thoughts before she was murdered. She asked me to watch over her son, and I intend to do just that." Kurama said.
"How are you out?" Rin asked, Isobu couldn't do that, so she was curious.
"Part of the seal that Minato used. This way I can better protect Naruto. He suspect that he will need it once Iwa figures out that Naruto is his son." Kurama said bringing up a great point.
"They won't figure it out! As Hokage I'm labeling Naruto's heritage an S class secret." Hiruzen said before Nagato put his hand on his shoulder.
"Hokage-sama, we have a lot to talk about. Why don't we wait until tomorrow before we make any decisions regarding Naruto-kun?" The young Uzumaki said making a face that made the old man's heart skip a beat.
"I think you're right, we've got to talk to the council first. I'll let them decide as a whole regarding Naruto-kun. Then first thing in the morning I'll address the village." Hiruzen said reminded of both Mito, and Kushina. He came to the conclusion that it is an Uzumaki thing before he took Naruto from Kurama and began walking to the council. Nagato followed him, being the new representative of the Uzumaki he needed to attend.
At the Council Meeting
"Where is the Yondaime? Why is this infant here? This is a serious matter. For that matter why in Nagato-san here rather than his sister?" One civilian asked rapid fire questions, only to be shut up by a blast of killing intent by the entire Shinobi council.
"There are many reasons why things are the way that they are tonight. First I regret to inform you that the Yondaime is no longer with us." Hiruzen said causing a massive uproar. "SILENCE! The second to last order that he gave was for me to take up the hat once more until a suitable successor is found. Next order of business is this child. He is the new container of the Kuybi." Another uproar, many called for the infant's death. Even though the Kyubi hadn't gotten into the village, it did still cause significant damage to the village during the fight to keep it out.
"Shut up Ningen I was under a Genjutsu put on me by some creature that possessed the eyes of none other than Madara Uchiha! It was a deliberate attempt to steal my powers and use them against the village again! I made a promise to this child's parents upon their dying breaths that I would protect him as if he were my own, anyone who attacks him will find themselves living impaired." Kurama said as his chibi form popped out of the infant's stomach.
"We were there, the Biju speaks the truth. This creature he speaks of identified itself as well as the others that attacked tonight as Zetsu. It possessed a set of Sharingan that it claimed to belong to Madara Uchiha, if Obito hadn't broken the Genjustu then Kurama here would've gotten to the village and leveled it." Kakashi said as he and the rest of the shinobi who played a major role in the night's events shunshined into the room.
"Anyway back to the matter at hand, tonight's events will be discussed in detail after this order of business. This child was born of Minato Namikaze and Kushina Uzumaki, both of which perished in tonight's events. This leaves us with a decision to make. Do we let it be known who his parents are, or do we keep it secret until he comes of age to claim his inheritance?" Hiruzen interrupted the current discussion in favor of getting this out of the way.
"I say we keep it secret, letting it be known would be like painting a target on his head." Fugaku Uchiha said trying to be sensible even though it would pain him to see his former teammate's son grow up in an orphanage.
"Let the attackers come, if they managed to sneak past the village gate's sensors, ANBU, Nagato, Konan, Yahiko, Kakashi, Obito, Rin, and my brother's they would be facing me. I may be weakened now, but I'm still more powerful than everybody in this room combined, excluding Isobu of course. To get to this child they would have to send seven nations worth of troops in order to even get close to the boy." Kurama said growling.
"As much as I hate foxes this one has a point. Wouldn't it be damaging to him to not know who his parents are for sixteen years. Keeping his heritage secret would also mean he couldn't live with Nagato, it could possibly kill his trust in the Hokage, and by extension the village. This plan runs the risk of creating a rouge Jinchuriki, the most dangerous type of nukenin with how strong they are known to be, especially in this ones case since the Biju within can roam free. I say we let the world know, and if assassins come we send a message of their heads in a scroll back to their village of origin. We take care of our own here damn it!" Tsume Inuzuka had a hard time not shouting her proclamation to the heavens.
One by one the entirety of the shinobi council began to agree with Tsume. Once the Nara clan joined the side of the Inuzuka clan all the others fell in immediately, including the Uchiha. The civilian council reluctantly agreed after the basics of sealing were explained to them by Hiruzen, basically how sealing a kunai in a scroll doesn't turn the scroll into a kunai. A few civilian councilmen didn't believe Hiruzen about Naruto not being the Kyubi though, as long as they didn't attempt any direct harm to the boy they would be fine.
"So it's decided, tomorrow during my address to the village young Naruto-kun's heritage will be revealed to the world. Now is the time to go over tonight's events and formulate a plan so that these events don't repeat themselves in the future."
AN: First off a general rule of thumb regarding Zetsu(s?), white=beaten by Yamcha from bragonball, Spiral=nearly Kage level, Black=almost as strong as Madara. Next a couple questions that I intend to answer before they're asked. Yes Obito's eyes have been destroyed function wise, no this is not permanent but it needed to happen for my plans revolving around the Uchiha massacre which will still happen, just very differently.
