Killing Zetsu
Konoha,
In the council meeting, Tsunade disclosed the fact that Shuichi was on an S-rank Mission all this time "not just that, during the pain attack, remember that scene where we were prisoned by some Ice dome? It was also done by Shuichi to protect the village from Pain's attack.
Koharu and Homura made me keep it as a secret as they don't want to leak the news that Konoha was saved by a traitor. It will make us a laughing stock and will lose our pride.
Traitor, my foot. If he hadn't returned at the right time, the entire Konoha would have been destroyed by Pain by now. Earlier, he reported me in private and passed the info about Akatsuki and their abilities that he gathered in these past two and a half years".
Shizune passed the information about Akatsuki to the clan leaders and two of the elders. They discussed it for a while.
Meanwhile, at Akatsuki Hideout, Black Zetsu's expression doesn't look good "damn it. How did this happen? Everything was fine until for a while. Shuichi even provided Kinkaku and Ginkaku voluntarily to seal Kyuubi's chakra.
How did he know about who really am? Not even Madara knew about me.
Three days ago,
After saying goodbye to Ino and others, He teleported to Mountain graveyard. He mumbled, "everything went wrong the moment Zetsu appeared. I need to eliminate him first so that, he won't resurrect Kaguya. As for the Bijuu and the war, let the five nations deal with them.
As the reincarnations of Ashura and Indra, it's their destiny to settle the matters between themselves. If Naruto ever became friends with Kurama and go into Bijuu mode, then, I guess, he would be more than enough to face Sasuke.
I already advised Hokage-sama to exchange the info with Gyuki's jinchuuriki training him. Well, everything depends on Hokage-sama now".
A while later, Black Zetsu who saw him spoke, "good that you returned at the right time. I got a piece of information about Orochimaru which will move our plans further without the need for any war against Kumogakure. In the past, he seems to have infiltrated Kumo when Hachibi is rampaging during Third Raikage's time.
Then, he took a sample of Hachibi's horn and cultivated it. It must have become a big one by now. Currently, there are only you, me and Tobi left now. you too lend us a hand and start to search for it".
Shuichi replied coldly "you don't need to waste your time. You won't find it ever because I already took".
Zetsu immediately was excited "really? that's great!!. So, what are we waiting for? I will find Tobi now and we will seal it right away. I'm excited that finally, after many years of waiting, my dream is going to be fulfilled".
Shuichi asked without changing his expression "Oh! how many years did you wait for? One year? A decade? A century?" He gave a couple of seconds pause and continued "Or a Millenium to revive your Mother?".
Zetsu was taken back by his response "What are you saying?". His Mangekyou Sharingan got activated while he raised his hand towards him "Absolute Domain". Zetsu immediately felt restricted by some invisible force.
He tried to escape from it, but for some reason, He was completely paralyzed. Then, he remembered this jutsu when he use it against Danzo before finishing him. But, unlike Danzo, as Zetsu is a chakra being, his chakra wasn't able to cut off from his body and was only able to restrict a little to move his mouth. Zetsu angrily spoke, "What is this, Shuichi?".
Shuichi was surprised for a second "wow, you were able to restrict it a little. I guess, living for a thousand years made you a bit strong after all, at that time, you weren't even able to handle a normal human being and got captured and beaten up".
Zetsu was shocked to hear that and thought "how?". Shuichi asked, "well, you must have thinking how did I know this. Aren't you?. well, it doesn't matter how I know. What matters is what I know. Well, considering your friendship with Teiji and since we're used to be partners for more than years, I'll tell you one little bit of information before you die.
Let's just say I knew everything that you had done until now with Indra and Ashura and their reincarnations to revive your mother. But, let me ask you one question. Why did you need me? You already have everything ready. It wouldn't matter whether I have Rinnegan or whether I become Ten-Tails jinchuuriki or not, right?".
White Zetsu who's in the disguise of Black Zetsu don't know how to answer and stayed silent making Shuichi filled with a little bit of anger "well, it doesn't matter anyway. Maybe its because you figured it out just like how did it with Indra's and Ashura's descendants. Goodbye Zetsu".
"Ice style: Absolute Zero".
The whole area around Zetsu began to frozen along with his body. Shuichi then spoke "well, you asked me before right. Now, I'm answering you that the jutsu is finally completed". an Iceberg formed around him and slowly the temperature began to drop to Absolute Zero and killing him.
Shuichi then disappeared from there and went back to Konoha.
After teleporting back, first, he called out "Hagoromo-sama, if you are observing me right now, please summon me right now". Instantly, his surroundings changed and he stood before Sage of the Six paths who is floating in the air.
He asked, "how do you know I'm observing you right now?". Shuichi shook his head "No, I don't know. I just guessed that you might observe me until I give you my answer". Hagoromo asked, "so, what's your answer?".
He replied "I'm going to the moon and fulfill Hamura-sama's wishes. Then, with newfound power I'm going to acquire, I will return to the Earth and then will take care of Akatsuki. But, I have a question I need to ask regarding Kaguya".
Hagoromo replied, "What is it? don't hesitate". Shuichi asked, "How was Zetsu going to resurrect Kaguya anyway? collecting Bijuu chakra and sealing them into the statue will resurrect Ten-tails. Then, Tobi will become its jinchuuriki and attain the level of your strength.
Then, later, he will send all the humans to the dream world but I don't see any connection of reviving Kaguya here". Hagoromo stroked his beard while explaining "its a simple thing Shuichi kun. You have seen our past right". Shuichi nodded. He continued "even though the method is different, the end result will be that they will be captured by God tree's roots and go into their dream world.
And the jutsu don't just send someone into a dream world for eternity, their chakra is also absorbed".
Shuichi frowned "that means..." Hagoromo nodded "yes. Once the Ten-Tails Jinchuuriki started to absorb the chakra of those who will be trapped by Infinite Tsukuyomi, He will become the vessel for her resurrection". Shuichi nodded and thought "I see, that's why.
Since I contain both of their chakras, I was a perfect vessel for Kaguya. But, since there was Madara in the plan, I'm not much needed unless Tobi and Nagato will betray him. So, that's why I'm considered as a backup. Anyway, I don't need to think much about it now since Zetsu is dead. Even if Madara is resurrected and won before I return, he won't absorb the chakra and will just satisfy with the fact that he saved the world. But can I defeat him alone with new powers I'll receive from Teiji's legacy? I hope so".
Present-day,
While Zetsu went to meet Kabuto once again to slightly change his plans, Shuichi who was wandering Moon for a while cursed when he reached a place where he found people and structures from a distance "damn it, Hamura-sama, you forgot to mention the fact that Otsutsuki clan developed right where Teiji's legacy is sealed away".
Meanwhile, at the main family residence, and elder reported to Sugai Otsutsuki, the direct descendant of Hamura and also the head of the Main clan of the Otsutsuki clan of the Moon "Sugai-sama, earlier we got a report that the Gatekeeper was killed".
He frowned "an unofficial entry?" then suddenly remembered something and got excited, "don't tell me he arrived?. Urata-san, seal this news completely and don't let that Toneri brat know this news. Send the most loyal ones and search for him in secret.
Amano-sama's prophesy never went wrong. We have to acquire Teiji-sama's legacy at all costs.
