The part where Hagoromo and Hamura sealed Kaguya and Black Zetsu came out of her.
"Mother gathered up every ounce of energy she had left, and just before the seal took hold, she gave birth to me," Black Zetsu said
"You...came out of her?" Naruto said
"Even Hagoromo did not know of this truth... Nor was he aware that I was working on her behalf to restore her. And so, that's how the battle between my mother and the brothers ended. But I was left with no power at all. That is why I went deep into the darkness, and carefully planned my mother's revival. In the meantime, Hagoromo was ignorant of all of this and raised Indra, Ashura and Minori. He even created that Ninshu Ninja Creed nonsense. Time passed and Hagoromo died.. and Just before passing away, he scattered the Tailed Beasts to various parts of this world. Two things are required to revive Mother... The Divine tree and Infinite Tsukuyomi by means of Rinnegan. But the Rinnegan requires Hagoromo's chakra, which he passed on to Indra and Ashura even Minori. ANd the Tailed Beasts, which form the Ten-Tails, were scattered across the world. In order to bring Mother back, all of these things had to be collected. You can't imagine the amount of time that was required to do this. So first of all in order to regain Hagoromo's chakra, I took advantage of Indra who lost the fight over succession. I tempted Indra and later I selected Indra's descendants, the Uchiha to be the cast of my tale. I revised the stupid script that Hagoromo wrote just a little bit," Black Zetsu said
"You mean," Sasuke said
"That's right. Hagoromo's Stone Tablet. I rewrote it to say the Infinite Tsukuyomi were the path to save the Uchiha. I must say... You Uchiha performed your parts brilliantly," Black Zetsu said
"WHy you," Sasuke said
"Indra, Minori, and the Uchiha, Ashura and the Senju. I was able to set up a pattern of fighting and power-seeking. Furthermore, time after time, I'd approach the reincarnate of Indra and Ashura in each clan to attempt Rinnegan Manifestation didn't know this time it will also be a Minori. But it always ended in failure. Just with that alone a thousand years passed. But when Madara Uchiha and Hashirama Senju were reincarnated, I came to believe... that Madara could achieve it. That this was the first step towards Mother's revival. However, Madara Uchiha lost to Hashirama Senju... I thought I had to go back to the drawing board. But Fate did not turn her back on me... Madara's corpse is like a treasure trove to a shinobi. Tobirama, who had been studying the mysteries of the Sharingan, stopped short of disposing his corpse. And instead, hid Madara deep within the mountains of the Leaf Village. But Madara was no fool... He figured that if he lost to Senju in battle. Tobirama would not get rid of his body so he placed a Jutsu on himself. You can invoke a time-delay spell in one's eye using the Mangekyo Sharingan. Just like the way Itachi implanted the Amaterasu with a time delay in you and y/n, Madara had installed the Izanagi in his right eye. At the cost of his right eye, Madara rewrote reality and returned to life. He then passed off a shadow clone as his corpse. He vomited the flesh he bit off of Hashirama, and grafted it on his wound. After that, Madara awakened his Rinnegan... and summoned the Gedo Statue. He then cultured Hashirama's flesh using the Gedo Statue, in an attempt to prolong his life further. Those groblins, the White Zetsu, seem to be an incidental by-product of that. But they were actually the people put under the last infinite Tsukuyomi whom I extracted from the statue. I just made it look that way. 'Two polar opposites operating together gives rise to all things in this universe.' Just as it was inscribed in the stone tablet, Madara solidified his attachment to Hashirama. I began formulating a plan... to collect the Tailed Beasts by making it look like. I was born out of Madara, and to also manipulate Obito. I formed the Akatsuki and steered them towards war. In order to increase battle strength, I deliberately let Kabuto discover Madara's corpse... And in addition, I guided him to use Madara's corpse as a bargaining chip, and Made Obito cooperate. This war went exactly as I planned. The Infinite Tsukuyomi was launched during this war... And by amassing a large amount of the human chakra that had been scattered... Mother was restored," Black Zetsu said
"I detest you... Hagoromo... Hamura... You are mine," Kaguya said while she used her Byakugan.
"My role has come to an end you shall return with me to the almighty God that is Mother, also it seems like little reincarnation of Minori passed out," Black Zetsu said
"Y/n!" Sasuke said but I was already passed out from the lack of air.
"You two aren't... you two alone aren't the entirety of shinobi history!" Naruto said ripping off Black Zetsu flying to Sasuke.
"Besides moms are supposed to be happy about their kids leaving the nest! That's what being a mom means!" Naruto said ripping it off Sasuke. Naruto and Sasuke both went to y/n pulled Black Zetsu completely off her. Sasuke held her in his arm shaking her.
"Y/n wake up we can't do this alone," Sasuke said soon y/n started to cough.
"Damn him almost suffocated me," I mumbled trying to get air back in my lungs. As Naruto and Sasuke signed with relief.
"Your teenage rebellion continues. Mother is the very progenitor of chakra. You brats can't hope to accomplish anything," Black Zetsu said as I floated next to Naruto with Sasuke still on the orb.
"Naruto, Sasuke we need to make an opening so we can launch the Sealing Jutsu," I said
"Yeah!" Naruto said
"right," Sasuke said
"And the only thing that will work... is that Jutsu!" Naruto said
"That 'Jutsu'?" Sasuke and I questioned
