With a swirl of distorting reality, Obito reappeared near the area of his initial defeat against the alien interloper. He was quick to hop into a tall tree to avoid a nearby trio of Konoha ninja; ANBU by their looks. He could easily kill them but there were bound to be more and he couldn't take on all of Konoha despite them currently recovering from the devastation wrought by him controlling the Kyuubi.
That and he could sense about a hundred more Jounin class chakra sources with a mile around him. Creeping along the branch, he moved some bushy limbs aside as slowly as he could accord given the time constraints of his purpose. It had been about twenty minutes after his defeat and he was sure the Konoha ninja were looking for clues as to where the Kyuubi could have gone, or the source of the massive attack that alien used.
It didn't take him a second to find the massive destruction left by that woman's scream. It dwarfed any technique he had ever seen or heard of, including the Kyuubi's. In the past, the final battle between Hashirama and Madara created an entire valley, which was only about a couple miles in length and about one in width. It was mostly thanks to Madara controlling the Kyuubi at the time to fight his rival.
The trench carved by the attack that almost killed him was easily three times the size of the Valley of the End. The beginning of the crater trench was about four meters deep and as many wide, but it expanded the further it went like a cone or triangle. The deepest part of the trench he couldn't even see from here but it had to be hundreds of meters deep and the ends was several miles wide, as well as about ten miles in length. He could only roughly guess since it was so massive.
He felt an unfamiliar and unwelcome alien chill trickle down his spine. Was this the most powerful of that woman, or has he yet to see anything yet?
He hopped through the tree branches when he was sure nobody would notice so he could make his way back to where he'd last been here.
Obito brought himself to a stop when he caught sight of the Third Hokage in his old battle armor standing over the unmoving body of the Fourth Hokage, a few meters away from them was a hole in the ground that looked to have been dug up.
His mind sped up as he tried to process what he was seeing.
Minato is dead?! How? Who could have killed him since I didn't? What about Kushina? She was near death as well but she's not here. It's possible the shinobi took her to a hospital but she wasn't in any shape to reseal the Kyuubi into herself, so… could she have sealed it into the child?
A closer glance with his Sharingan didn't reveal any wounds on Minato's body as the shinobi checked it over for a cause of death.
Minato's dead but no visible wounds. Kushina's missing, but possibly in the village, and the Kyuubi IS missing. No tracks around here to tell where it walked off. So, it most likely was sealed again, but where? Knowing the Fourth's "village comes first" mentality, he likely made his child the jinchuuriki. I would have kept Kushina alive enough if I could have foreseen this, just to see her beat the hell out of him for making their child a human sacrifice.
However, this leaves the question of where Kushina is and why Minato was buried in such a manner, like a common ninja. It's definitely unlikely a Konoha ninja buried him there instead of in the Hokage graveyard. That would mean it wasn't by Konoha's hands. That would only leave… the alien woman.
His hands clenched into fists at the likelihood of that woman throwing his plans into disarray even more.
For what purpose would she do that? I need to confirm Kushina's status first.
Thankfully, a trio of ninja was running towards his location after receiving an order from Sarutobi. He leapt back a little distance and as they neared his spot, he used the transformation jutsu to disguise himself as a Konoha jounin, Orochimaru to be precise, and jumped down.
His sudden arrival caused them to react accordingly given their emergency state and draw weapons before they recognized one of the legendary Sannin of Konoha.
"Orochimaru?! Weren't you on a mission?"
Luckily, Zetsu kept tabs on the most notable Konoha ninja at the time since he was planning this attack, so he was often kept up to date on their movements outside of the village.
"I was on my way back when I ran into a search party several miles away. They informed me a little of the attack. They said Namikaze went missing after the Kyuubi attacked the village but that's all they knew." He knew he was taking an educated guess on this gamble since he just saw Minato's body being discovered, as well as making up the search party he "met". If there were some around now then he was probably several minutes late to when the search began.
"Tell me what has happened? Kushina Uzumaki was the jinchuuriki of the Kyuubi and it never showed signs of weakening. What are her status and the status of the village?"
He was thankful for the convenient help of his Sharingan to coax them into spilling what info they knew on the subject. The one who was probably leading the group answered him.
"The village has suffered catastrophic levels of destruction, but not as bad as it could have been had its interest in us not been overtaken by a massive explosion just nearby. You can't miss the damage."
Obito minutely twitched at the reminder. "Unfortunately, the Fourth Hokage was just found… dead, but with no signs of mortal wounds. It's like he just lost his soul or something. No marks on him or anything, except some slight bruising to his testicles, as if a large person stepped on them."
Well, that certainly answered his question and gave a foundation for his theory. Minato brings Naruko and seals the Kyuubi since Kushina would be too weak and the alien wouldn't know anything about the sealing arts. Then, based on the evidence of his body, he must have used a sacrificial jutsu to seal the Kyuubi into the baby. He dies and the path splits in two ways: Kushina dies and the alien takes the body and the baby (since she made such a big deal about attacking a baby's mother *rolls eye*), or she was somehow able to heal Kushina and took in both her and the child before the Konoha shinobi arrived. Either way, with the Kyuubi out of his reach, he would have to invest research into alternative means of accomplishing his goals since it couldn't be done with the Kyuubi's chakra.
He nodded and rushed towards the area he just left. Once he was certain the group restarted their search, he disappeared into his Kamui dimension.
