The War declaration of Uchiha Madara

As the 4 kage of each village was already inside the room where the summit will be held. Tsunade and co were late due to kuro's requests.

Flashback to when Danzo was defeated

"Hokage sama. Can I have your permission to have this guy's sharingan?" he asked seriously.

Tsunade turned to kakashi. And kakashi nodded as if he agrees to kuro.

"sigh, fine. Since you singlehandedly defeated the enemy yourself, let's just say it's your reward for doing so but! don't ever do that again! Do you hear me?" tsunade reprimanded kuro however his attention was on danzo's prosthetic arm.

"Tsunade sama. I think that arm has your grandfather's cells. Danzo did say it himself that he was part of the invasion on konoha led by orochimaru years ago. Then if that's true he must also be part of orochimaru's experiments on humans. And this must be the product of that." explained kuro as he took the hand and looked at tsunade as if he's trying to mean something.

"So do you also want to implant a sharingan just like kakashi here? Is that why your looking at me like that?" tsunade ask as if reading kuro's thoughts.

"Not necessarily. I just need your help on taking out these eyes so we can return them to their clan. Who better to give it to than the only surviving Uchiha in konoha at the moment?" kuro corrected

"Humph! I thought you said you wanted to take it for yourself?" asked tsunade in annoyed manner

"Of course I do. But I will take the one on danzo's right eye. Also I'm not planning to implant it right now. Maybe in the future? or maybe never.? hehe" kuro said sheepishly while thinking something

'I really despise this way of getting power but who wouldn't want kotoamatsukami's power? of course I'll need to find a way first to be able to deactivate it or maybe seal it when I ain't using it. I think Lord Pink will be able to help me with it. She's basically a scholar when it comes to seals. Sigh... Mom, Dad. I won't ever let you guys be in danger and die while i am around.' kuro has changed inside and he was not able to notice it. When he came to this world he was so focused on being strong to be able survive but still maintained that humanity in him as someone who came from a peaceful era without war. He wouldn't have considered thinking of this before but now, he would go as far as turning around that humanity in him just so he could gain power to protect his loved ones.

"Tsk fine then let's get it done or we'll be late for the summit" complained tsunade but still did the work. They were first removed by tsunade from danzo and was carefully placed inside a small container before kuro sealed it. He sealed shisui's eyes separately as he has another plan for it unlike the others that he plans to give to sasuke.

He also took a pinky from the prosthetic arm as he also wants to learn the 1st Hokage's cells. Although it goes beyond his morale as a human to gain power, it cannot be helped. Ever since that night when his mother died. It woke him up that this is now his reality. And he needs these things if he wants to be able to save his family or even himself. As someone who watched Naruto Shippuden and has knowledge of what's to happen. He knows he needs such power especially when facing the 10 tails or it's jinchuuriki. Preventing them from ever appearing has been on his mind but there are things you just can't control that's bound to happen. Especially if kaguya emerges still.

Kuro then marked kakashi and tsunade's clothes saying he's just going back to konoha in a moment to give Sasuke the eyes and good news about danzo's death and probability of his brother able to return to konoha. However before he could teleport back and vanish he lost consciousness as tsunade knocked him out by the back of his head.

"Jeez, he's a handful. I should be saying that I'm regretting choosing him on this journey but he just did a good job there. kakashi carry him all the way will you?" Tsunade was stressed out at kuro's behaviour of doing things as he likes. And kakashi is the one suffering because of it. Their journey was slow due to this and each time kuro gained consciousness he would immediately say he's going back to konoha in a bit so tsunade had to knock him out 2 more times. But in the 4th time kuro gave in and does not want to loose consciousness again. So they had to pick up their pace so they can make on time for the summit.

Flashback end

"I wonder why the Hokage is late?" asked the mizukage.

"Humph.! She must be showing off because she's a descendant of the one titled God of shinobi. The strongest shows up last. This summit about the akatsuki must be just a joke to them." commented ohnoki.

"Lady tsunade is not like that. As someone who was saved by konoha when I was taken by the akatsuki as soon as they heard of my capture, I can testify that this summit is important to them as much as it is important to all of us" gaara seriously answered back.

"You're still young and naive if you're thinking like that. You're still new on how to run a village. As your senior I will give you a chace to ask anything you'd like. l'll answer anything at all" ohnoki stated as he was annoyed by gaara's description of konoha. Kankuro almost shouted but stopped as Gaara was faster than him.

"Then let me ask you this."

"Sure go ahead. Don't hold back kid"

"When did you forsake yourself?" Ohnoki was shocked by the question and was shutted down, mizukage smiled at this while raikage gritted his teeth.

"We actually understand what you're saying kazekage, but-" raikage didn't get to finish as tsunade and co suddenly came inside.

"We're really sorry for being late we ran into some small trouble along the way." apologized tsunade as she sat down on the chair designated for her while kuro and kakashi remained standing a distance behind her.

"Humph let's just get this summit started with already" ohnoki initiated.

Every kage nodded in agreement. The topic was pretty much about the akatsuki and what countermeasure they are going to take as to their knowledge 6 of the bijuu is already in akatsuki's hands. Anyone could guess what a criminal organization is going to do with all that power in their hands.

"My fellow kages. You might not know of this since it recently just happened. But the leader of the akatsuki named Pain is already dead. He died when he attacked konoha openly and tried to take the nine tails." this information shocked everyone present except on konoha's side.

In this summit not only were all the kages of each village present with their escorts. They are also joined by the general of the land of iron Mifune. Mifune is known to have faced hanzo alone even when his fellow samurai turn tail and run at the sight of hanzo the salamander. The land of iron is always neutral during ninja wars.

[ AN: That's all I know about them so let's leave at that...LOL ]

As they were all shocked at tsunade's information. The center of the summit has an open space since they are in a circled formation. Something was coming out. As the figure came out, it was a man with short black hair. He has a mask on with a spiral design and the center of the spiral has a hole aligned to his left eye where you can see that he has a sharingan. His outfit is that of the akatsuki black coat with red clouds.

[ AN: If you know tobi/obito then you know exactly how he looks ]

Everyone was tensed and on guard as tobi introduced himself.

"I am Uchiha Madara the true leader behind the akatsuki. I was actually eavesdropping and just waited for all of you to be present. Pain was only acting leader on my behalf since I needed time to recover myself from the injuries I received from Hashirama Senju" obito declared in front of them as he shown his sharingan through that small hole from his mask.

A katana came flying straight at him but raikage was faster than it. Both raikage and the katana went through him and everyone was shocked to see it besides kuro since he knows this ability.

'I know I already copied and modified your Jutsu but I may need to do it again minato san' kuro thought to himself

As Raikage was faster, he already hit the wall while the katana was still behind obito. Kuro seized the moment and teleported there while already on a form of slashing downward. Obito who thought it was all over almost put his guard down but by reflex he remembered this situation when minato hit him with a rasengan using the same tactic so the surprise attack didn't work as he was subconsciously on guard. Kuro didn't wait for the katana to come out of obito's body. He immediately teleported out of there and returned to where tsunade is.

Everyone was surprised multiple times. It was when Raikage and the Katana went through obito. And then kuro surprise attacked obito and they all felt that obito did put his guard down but by some unknown reason he was able to put his guard back up in a single moment. If he didn't he would have been injured or probably died. They could only think that it was due to him being a war veteran that his body reflexes was that fast and that it was honed by experience. In other words, It can be interpreted that he was indeed uchiha madara. This was running through almost everyone's mind excluding kuro and the raikage who hit the wall after passing through obito since he wasn't able to see what kuro did.

"My apologies Hokage sama. I thought he let his guard down, it seems he remembers the move I just used. He must have faced someone with the same ability before." kuro respectfully explained. Although it was because he already knows it but no one would be able to deduct that in just a moment like he did.

"What do you mean? your ability is quite similar to that of the fourth Hokage is it not? Are you saying that he's faced the fourth Hokage before?" asked ohnoki who was the first to get himself back up through all the surprises.

"Correct! It was about 16 years or so ago. When the nine tails jinchuuriki which was the 4th's wife is giving birth to the current jinchuuriki Uzumaki Naruto. The seal of a jinchuuriki weakens during childbirth which gave me the best opportunity to destroy konoha. But that 4th Hokage, although he's not on par with Hashirama Senju's prowess. He was indeed a genius for being able to use Tobirama's jutsu and perfected it in his own use." obito paused and looked at kuro "You must be the Red Flash. Conan was right, you do hold a lot of information about us. I wonder how much you do know" obito clarified it himself. 'Just how much really does he knows about all of us. This red flash is a a thorn in my path. He most probably already knows what I just said since he deducted that I faced minato sensei before but does he also know who I am??' Everyone was once again taken aback by the information given by the masked man who introduced himself as Madara.

However it was tsunade who answered him first. "So it was you who attacked konoha using the nine tails that night. I should kill you myself! right now!"

"Indeed it was me. However you might want to hold that thought about killing me right now since I did come here to declare war against all the villages so you'll get your chance to kill me still later on. My objective for this war is to take the Nine tails and the Eight tails bijuu. You can stop me however you want but once I have captured them both. Victory will be mine and peace will come to this world." obito declared proudly.

"What do you mean? How exactly are you going to use all of the bijuu that you have captured.? Are you going to oppress the world using their combined power??!!" asked gaara

Then obito explained to them how the uchiha has a stone tablet stating legends about how their clan is connected to the sage of the six paths. How all the bijuu were once a one being called the 10 tails and how it was all the bijuu's origin before they were split apart by the sage of the six path himself upon reaching his life's end. How the sage of the six path was the 1st jinchuuriki of the 10 tails himself and how he plans to be the next one. And finally about his plan of casting a powerful genjutsu to all humans around the world. And will finally achieve true peace. He called it project tsuki no me.

"That world is only made of deception. It's meaningless. Unless it becomes a reality it has no place in this world." Gaara commented but obito answered back.

"Hope is the same as giving up. That's why there's no other way than to make it a deception."

Everyone frowned but one person.

"How weak. That must be the reason why you lost to the 1st Hokage. Because your a hopeless person." kuro laughed which made everyone else smile.

"I admit that he defeated me that day. But it was also after that time that I have become even more powerful...Therefore, I hereby declare the 4th Great Ninja War.!" Obito shouted as he was about to leave using kamui but stopped immediately as a katana was passing through his throat. 'tsk! he's annoying and persistent!.' he thought as he was forced to use kamui in a different manner. Everyone else but kuro's companion was surprised yet again.

'This kid is going to kill me with all of his surprises!!' thought ohnoki

"Hmmmmn... Nice reflex. And when do you plan to start this War you speak of?" asked kuro seriously while still holding the katana through obito's throat but obito was slowly sinking to the ground where he first came.

"A month. That's all I need to win against all of you." obito gave his answer and left the room where the summit was held.

A few moments later the Kages decided to form the alliance. The roles were still the same as Canon. Kuro being there was no longer surprised. Things has been progressing even without him interferring with the timeline. He deducted that even with him being there some of the main plot will still happen in a good or bad way. Sasuke being the good as he wasn't lost in his revenge and Orochimaru being the bad one as he's still out there with all his abilities. He's not gonna be surprised if Orochimaru will replace kabuto by completing Edo Tensei and join hands with obito.

4 days after the summit the ninja world was shook to it's core. Uchiha Madara was alive and declared war against the whole shinobi world.
