It was an ordinary day in Konoha. The rookie 11 and the sand siblings were going on a group mission with their senseis and some joinin. Their mission was to train in the forest until they were ready. Suddenly the group noticed a portal to something. They decided to partner up and go check it out. They drew lots. Uzumaki Naruto was with Hyuuga Hinata, Inuzuka Kiba, with Akamaru as his ride, was with Aburame Shino, Rock Lee was with Haruno Sakura, Yamanaka Ino was with Nara Shikamaru, Hyuuga Neji was with Tenten, and Subaku no Temari was with Akimichi Chouji., which left Subaku no Gaara to go with his older, yet weaker brother Subaku no Kankuro. Everyone went in with their partners holding their hands. Nobody expected the Akatsuki or the Sound Ninja to follow them. The last thing they remembered was that they blacked out.
(With Naruto and Hinata)
Uzumaki Naruto woke up and saw that he and Hyuuga Hinata were in a park. Hinata woke up five minutes after he did. He looked around his surroundings and Hinata checked with her Byakugan. They said in unison, "I don't think we are in Konoha anymore." They were about to pass out when they saw a short, Asian girl with glasses and wearing a blue sweatshirt asking them if they were ok and the weird part was the girl spoke no Japanese to them and they understood what she was saying. The girl called for her parents and the next thing they know they were being brought to a house.
(With Kiba and Shino and Lee and Sakura)
Kiba and Shino woke at the same time to see that Rock Lee and Sakura landed with them and awoke with a thud. As soon as Lee and Sakura woke up, they wondered where they were. Akamaru started sniffing the ground but found no trace of their village. A tall lanky boy took them to his house.
(With Gaara and Kankuro)
When they woke up they said the same thing, "What the Fuck?" before passing out, as they were being carried by a short dark-skinned boy and his equally dark-skinned brother.
(With Temari and Chouji)
They woke up in a room that was cold and was filled with meat hanging from hooks. A tall chubby, red-haired man with glasses and an apron came in and brought them in from the meat freezer.
(With Neji and Tenten)
Neji checked his Byakugan as soon as he and Tenten woke up and was amazed to find they weren't even in the same dimension as when they first started their mission in the first place. A fat boy that was bald and had a blue backwards cap took them to his house.
(With the senseis and jounin)
"Uh…. Where are we?" the jounin asked all together as they were being brought to an unknown location by a short blonde boy.
(With Shikamaru and Ino)
They woke up in a girl's room that was all pink. They saw two doors. When they checked one door, they found a shrine in a closet and then they closed it quickly, not wanting to scar themselves. They heard something and passed out.
