A note first: ©Naruto is owned by Kishimoto, Shonen Jump and some other company or dude I forgot about 😥.
As the last rays of the gleaming white light of the sun shrank, and the Sealing Jutsu: Planetary DevastationCatastrophic Planetary Reconstruction, showed itself, a figure wearing a mask with only one eye hole slipped into the Village Hidden in the Leaf. The masked figure, who was once known as Obito Uchiha, replayed what had happened exactly 2 years ago inside his mind. The Hidden Mist ninja, the Chidori, Rin… Rin! RIN! It was all he could do not to yell out loud.
"Kakashi, you little fucking bastard… You once told me that I have no power… I wonder what you might think about that now…"
"Hey, who are you?" it was an Anbu member, probably from the Foundation, wearing a tiger mask. "Are you Anbu? I don't recognise you, yet your chakra is somewhat familiar…"
Suddenly Obito realised exactly who was behind that Anbu mask.
"What's your name? Are you from around here? I feel like I've seen you before…" Kakashi Hatake asked.
"I'm called Tobi," the man replied. Tobi fought the urge to sink a kunai into his former teammate's heart. Or use his Wood Style, heck, even a good Kamui to rip open Kakashi's chest cavity seemed like a great option. But now was not the time, nor the place.
"I'm called Kakashi, and I shouldn't be here right now, I should be buried under a cave," Kakashi's blunt tone replied. "Tobi"-Obito, smiled a smile devoid of humour. He dipped his head, and turned into an alley.
"Not the time, now is not the right time." Obito told himself. "After all, my main goal of this infiltration is still yet to be achieved."
Obito reached where he was supposed the 4th Hokage's house was. Now, just to get inside without triggering the barriers… That isn't so bad, it's the two people inside that are the trouble.
"Minato Sensei, you were late, just like always. That's just who you are. WEAK!"
With that, Obito activated Mangekyou Sharingan and teleported himself 2 steps from the door with the barrier 1 step behind him. He then easily slipped through the door as if there was nothing in front of him. Now, he carefully stepped into the household. The Jinchuriki, he could sense the Demon Fox's chakra. Imagine, with the training he received from Madara, he could control that power… what he could do with it.
Shaking of his daydream, Obito slowly cast a hand seal and created a wood style clone which then promptly turned and merged with a nearby sakura tree. That was his look out, just in case someone showed up.
"Now, to finish this bothersome job… man, I wish Zetsu had more guts, so that he could do this," Obito regretted. But, nevertheless, he continued forwards. Suddenly, he stopped dead.
"I never thought that there would be an Earth Style trap buried in the hallway. Minato sensei wasn't a user of Earth Style… does this mean that Kakashi is guarding sensei's child and that annoying woman?" Obito carefully studied the hallway, "I see, so the Earth Style will push me into the ceiling, which would possibly kill me, and further up the corridor is a Fire Style: Paper Bomb Jutsu… the Earth Style isn't too noisy, should be simple to just phase through it using Kamui, but the Fire Style, that would be too loud, and I can't just teleport upstairs without knowing exactly who's up there either. Uh, so be it.
Wood Style: Deep Forest Reconstruction! The Jutsu teleports pieces of wood to other places with wood, and replaces the missing wood that has been teleported with pieces of new wood. Obito had trained hard with Zetsu after they had discovered that he was a user of Wood Style. Now, he just need the information.
"Would that be in sensei's office, the kitchen or the bedroom?" Obito wondered. The kitchen wasn't very likely, the office seemed like an option, but if it was the bedroom, he would have to take down the Jinchuriki, and likely the noise would make an alarm. After all, the Jinchuriki was an Uzumaki, plus her Sealing Jutsu was apparently unrivalled, and even worse, she was strong enough that a HOKAGE fell for her.
"Too risky… wait, what was that thing Rin used to say? Nothing is too risky. Oh, wait, that was what I always said." Obito made up his mind… if he had to fight to get what he wanted, he was gonna go right at the challenger. He slipped up the stairs-if he had to fight, no sense in trying to avoid attention. He approached the bedroom.
Well? How was it? Give a review and decide what happens next:
Kushina Uzumaki is in the kitchen and Obito doesn't fight her
Obito fights Kushina and wins
Obito fights Kakashi
