In fanfiction, Naruto's reaction could vary. If they prank him by making him think he's becoming Hokage for a day, he'd be over the moon at first. When he finds out it's a prank, he might be a bit sad but also see the humor in it. He might say something like 'You guys got me good!' And if they swap his kunai, he'd probably be a bit annoyed at first but then turn it into a joke. He'd probably show off the goofy kunai to other people and say 'Look what my friends did!'
Naruto might initially be shocked or confused. For example, if they prank him with the fake ramen, he'd probably make a really funny face when he takes the first bite. But then he'd probably laugh it off because he has a good sense of humor.
Sakura would probably be shocked at first, but then she'd be supportive. She might offer her medical skills to help with Tenten's pregnancy. Shikamaru would likely think it's a troublesome situation but would also offer his strategic advice on how to handle things. Kakashi would be his usual calm self and give them some wise words about responsibility and family.
His friends from Team 7, like Kakashi, would feel responsible for Naruto's situation. Kakashi would likely use his resources to find a proper shelter for Naruto. Shikamaru and the others might come together to form a sort of support group for Naruto. They would pool their resources, like money and food, and also try to cheer him up by sharing stories and jokes.
Sakura would be really happy for them. She has seen Naruto grow and has always wanted him to find true love. Since she has moved on from her old feelings for Naruto, she would be supportive and might even offer to help with the wedding preparations. Shikamaru would probably be a bit lazy about it at first, but deep down he'd be glad for Naruto. He'd say something like 'What a drag, but if it makes you happy, Naruto.' Kiba would be excited, especially since Hinata is his teammate. He might tease Naruto a bit about finally getting the girl.
Their friends' reactions would be quite diverse. For instance, Ino, who was once Sakura's rival, would have a mixed reaction. On one hand, she would be happy for Sakura as they have grown to be friends over the years. On the other hand, she might feel a bit envious. Choji would be excited and would look forward to all the feasts at the wedding. As for Lee, he would be over - the - moon for Naruto and Sakura. He would probably give them some long - winded and passionate speeches about love and friendship.
Their friends would likely be very concerned. Shikamaru, being Temari's close friend and Naruto's teammate, would try to use his intelligence to figure out what's wrong. He might start by just spending time with them, not pushing them to talk right away. Sakura, as Naruto's long - time friend, would probably be more direct. She'd try to get Naruto to open up about his feelings, using her medical knowledge to also check if there's any physical ailment contributing to his depression. For Temari, Ino could reach out, as she's good at getting into people's heads. She'd offer Temari support and try to make her feel better about herself.
Shikamaru, being the more laid - back but perceptive friend, would likely be disappointed. He might see the signs that led to the divorce coming from a mile away but feel powerless to stop it. He would probably just sigh and say something like 'What a drag' while still being there for both Naruto and Hinata as a friend.
Naruto's friends like Sakura and Kakashi might be initially shocked. Sakura, as a medical ninja, would offer her medical expertise to help Cana during the pregnancy. Kakashi would probably be more reserved but offer his wisdom and protection. On Cana's side, her friends from her own world might be skeptical of Naruto at first, but as they see how much he cares for Cana, they start to accept him.
There could also be friends who are so loyal to Naruto that they would consider following his request if they truly believe it's for the greater good. However, they would be deeply pained by it. Kakashi, for instance, might understand Naruto's selfless nature but would also struggle with the moral and emotional implications of taking his life.
There might also be a sense of self - doubt. Naruto may start to question his own judgment. He thought his friends were true to him, so the betrayal could make him wonder if he was wrong about them all along. He might also doubt his own worthiness as a friend and leader, which could have a long - term impact on his self - esteem.
Sakura might be a bit surprised at first. But she would probably be happy for Naruto as long as he is happy. She might also be curious about the elf and want to learn more about her. Sasuke would likely be more reserved in his reaction. He might not show much emotion on the surface but deep down he would be glad that Naruto has found someone. Kakashi would probably give Naruto some sage advice about making a relationship work, especially since it's with someone from a different species.
