This Fanfiction written on the time set few days after Naruto won the war, in this AU Sasuke didn't left the Village to redeem his sins.
For attack on Titan this is written on the AU, before the season 3.
Naruto walked away from the Hokage office along with Sakura and Sasuke, the team seven has reunited. They just finnised their mission and heading back home, the 4th great ninja war really caused trouble, most of the shinobis from Konohagakure busy with their mission, especially Sai-who was accompanied Captain Yamato to watch over Orochimaru-. Naruto gazed up, looked at the sunny sky, it's been a while since the sky was this sunny, the voice of the villagers who looked them as heroes heard.
" Looked it's them!" a man yelled.
" Kohonagakure's strongest team!" a teenage girl yelled.
They smiled, especially Naruto who gave them a big smile and a thumbs up. Sakura smiled and waved her hand to the kids that adore the trio, while Sasuke stay the way he is.
" it just like old days right?" Sakura broke the silence.
" Yeah, but now we did this on our own, and recived mission from Kakashi sensei" He said with a big smile.
Not just it, Sasuke is here. Just like when they were 12, before Sasuke left the village. Naruto separate himslef as he walked to his house. When he arrived all he do is eating instant cup ramen and went to sleep even though it was still to early, but he didn't care anyways he just to tired, even though they just use a small amount of chakra. As he fell into a dreamless sleep, he didn't know that he'll get more tired than that.
Sakura brushed her hair inside her room, she noticed that her bakugyou mark is return to it's full power. Of course her chakra is fully recovered, so did most of her friends. Not to mention Naruto and Sasuke, who was completely recovered within just two days. Night soon fell, she clean her self and prepared to go to bed, just when her put the blanket on. She heard a knock on her window, she slowly woke up. Behind the curtains there was a silhouete on a young man which she knew.
" Sasuke-kun?" She called as she walked to the window. She opened the curtains, she shoked it really was Sasuke. But he held his katana thightly while his eyes looked wary as a battle will started anytime soon.
" Your ok? Have you seen Naruto?" He asked.
Sakura shook her head, " Wasn't he supposed at his house?" She asked, then saw the look on Sasuke's face. She understand it clearly.
" Be prepared, there's an unknown shinobi in here."
As Sasuke left, Sakura changed her nightgown into her normal outfit and jumped out of the window to follow Sasuke. She steps into a roof and found Sasuke talked to her other friends. Shikamaru, Choji, and Ino. They were all alret by that unknown Shinobi who entered the village, once they found out about Naruto disappearance, they rushed away to report this to the Hokage at this time to Kakashi. When Sakura and Sasuke alone, someone was behind them. It is him, the unknown Shinobi before the two could do barely anything. That shinobi said something, soon a bright light showed, Sasuke and Sakura covered their eyes. The light swallowed them, and bring them to somewhere Naruto is.
Naruto opened his eyes slowly, his head felt really heavy and dizzy. His vision still blurred, he tried to move his body slowly and slowly, he finally managed to sit. As his vision gets clear, he rubbed his head. After he got his vision back, he looked around with confusion, he was on a huge branch on a huge tree. He did know how the got here, suddenly remembered.
Flashback
He was going to the bathroom at late night back at Kohona, it was 9pm he felt hungry he wears his mormal clothes black and orange jacket and not forgetting his head band as he gone for a mission. It was just a normal night walk, until he met someone with a brown cloak, he stopped few feet from Naruto.
" Naruto Uzumaki ka?" A voice of a girl was heard. Suddenly lights out, few blocks around them became a total black.
Naruto held his kunai tightly with his right hand, but the cloaked girl stay still. She disappeared in the darkness, but he still heard her voice.
" Say, Naruto Uzumaki the jinchuriki of Kyuubi, reincarnation of Ashura, son of the fourth hokage, hero of the 4th great ninja war, a HERO!. Would you like to be a hero, once again?" The voice echoed inside his head.
" What the hell does that mean?!" Naruto yelled, suddenly a black smoke covered him in a flash.
" Ahaha... you little knuckle head ninja, i want you to be another hero, in other world. Don't you worry, once you become a hero, you will return here." The voice was heard once again.
Naruto screamed louder,
" Do not be worry Naruto Uzumaki, i'll bring you, your friends. The second Tsunade senju, and the last uchiha.." As the voiced laugh in the abyss, Naruto felt himself being sucked into some kinda portal, then disappeared from Konoha, and from this World.
Flashback off
" So, this is the other world that the girl mention huh?" Naruto said to himself, he jumped from one tree to another.
Then, he decided to get to a higher place, and tried to find a way out from his forest. At the top, he saw a huge area, not just it he saw some strange giant human creatures. Each of them looked different, from 3-15 meters tall, not just it. They have wide mouth and had no genitals, Naruto continued to jump from a tree to another, try to get out from the forest. As he find his way out, some of that weird looking giants looked at him. Naruto stopped, and yelled.
" Hey you! What are you doing there?"
The giants didn't answer, they tried to grab Naruto. But of course the shinobi avoid it like a piece of cake. At that moment Naruto knew those weird looking giants tried to eat him. Naruto gave a smirk of smile.
" So you wanna eat me? Well, eat this!" He made a hand seal.
" Multi Shadow clone Jutsu!"
5 shadow clone appear and launch punch to the giants, they punch but nothing happens. Those giants just keep regenerate them self, Naruto along with his shadow clone keep attacking those giants. But, more giants coming, Naruto bit his lips, he's about to preform Rasenggan. Until he heard a familiar voice.
" Chidori!"
Sasuke appeared, his katana held tightly, silicing the giants fiecerly. Then another voice was heard, this time a girl.
" CHANARAAA!" Sakura apear out of nowhere, but Naruto sure that she's with Sasuke.
" Found you idiot" Sasuke said as he looked at Naruto.
" Thank you, bastard. Now how the hell we stopped them from regenerate?" Naruto looked, at the giants who keep appearing.
The three of them keep fighting the giants, but hid their power. They all at least just use 2%-5% of their chakra.
