His other friends like Shikamaru would use his intelligence to analyze the situation. He'd try to figure out what kind of jutsu Tsukuyomi is and how it works. Then, he'd come up with a plan. Choji would be there to support everyone physically, ready to fight any threats that might come their way while they're trying to rescue Naruto. And Kiba with Akamaru would use their tracking skills to see if they can find any leads on who trapped Naruto in Tsukuyomi.
Well, Naruto could be trapped in Tsukuyomi and face his inner fears. Maybe he sees his friends in danger and has to find a way to break free to save them. He might relive past failures and use those experiences to grow stronger mentally while in the illusion.
Sakura would probably be very angry at Kurenai. She's protective of Naruto and would demand an explanation. She might even try to heal Naruto right away if it was a physical injury.
Sakura would be furious. She's always been protective of Naruto in the original Naruto series. In the RWBY fanfiction, she would probably start her own investigation to find out who was behind the betrayal. She might even challenge the RWBY characters if she thought they were involved. Kakashi, on the other hand, would be more calm and collected. He would try to analyze the situation rationally and figure out the best way to help Naruto.
Sakura might be initially surprised but would probably be supportive. She has always cared about Naruto's happiness, so as long as he is happy with the elf, she would be okay. Kakashi, on the other hand, would likely be intrigued. He's seen a lot in his life, but an elf - ninja union would be something new. He might offer some sage advice based on his own experiences with different cultures.
He would be heartbroken. Naruto values friendship above almost everything. At first, he might not believe it and try to reason with his friends.
His other friends like Shikamaru would think of the most practical solutions. He might calculate the risks of continuing the mission with a sick Naruto and come up with a plan. Maybe he'd suggest splitting the group, with some staying to take care of Naruto and others proceeding with the mission - related tasks that can't be postponed.
Naruto would be extremely hurt. He values his friends above almost everything, so their betrayal would be like a knife to the heart. At first, he'd probably be in disbelief and try to reason with them. When he realizes they won't listen, he might become angry and lash out. But deep down, he'd still hope to win them back.
Well, Sasuke might initially be angry. He and Naruto have a deep bond, and Naruto leaving Konoha for another village could seem like a break in that connection. Sakura would be heartbroken. She's always cared about Naruto, and seeing him go would be difficult for her. As for the others, like Kiba and Choji, they might feel like they've lost an important part of their team. They would wonder if there was something they could have done to keep Naruto in Konoha. However, over time, they might come to accept his decision if they see that he's happy in the new village.
Naruto's friends would react in a very emotional way. Hinata, being his wife, would be devastated. She would stay by his side constantly, taking care of him and their children as best she could while also hoping for a miracle. His friends from the Rookie 9 would all come together. Kiba might bring Akamaru to try and cheer Naruto up, while Shino would be more quiet but still show his support. They would all band together, using their unique skills and abilities, whether it was in combat, medicine, or just emotional support, to try and make Naruto's last days as good as possible.
His other friends like Shikamaru would use his intelligence. He would analyze the situation, figure out who is behind Naruto being thrown in jail, and then come up with a clever plan. He might gather the other members of the Konoha 11 and together they would work to free Naruto while also trying to expose the truth behind his imprisonment.
