His friends like Kakashi would be cautious yet supportive. Kakashi would likely give Naruto advice on how to handle the relationship and the responsibilities that come with it. In Kirigakure, Mei's comrades might initially be distrustful of Naruto, but as they see his good intentions and how he treats Mei, they would gradually accept him. And Naruto's friends from other villages he has befriended over the years would see it as a positive step towards a more unified ninja world.
Kakashi would be more of a supportive figure. He has seen Naruto and Sakura grow up, and he would likely be happy for them. He might offer some advice to Naruto on how to handle this new relationship, especially considering the challenges they might face as ninjas. For Sakura, he could give her words of encouragement to be true to her feelings.
Sasuke might initially be a bit aloof but secretly be happy for them. He's always had a complex relationship with Naruto and Sakura, and deep down, he would see that they are good for each other.
At first, Naruto would be in disbelief. He has always trusted his friends wholeheartedly, so this would be a huge blow. He might then feel a deep sense of anger and sadness. However, Naruto being Naruto, he would likely also start to look for ways to prove his innocence or the misunderstanding. He might go on a journey of self - discovery to figure out what went wrong and how he can win back his friends' trust, all while dealing with the pain of the betrayal.
His friends' reactions would vary. Hinata would be really happy for Naruto. She would be gentle with the little girl and offer to make her clothes or cook for her. Kiba might be a bit skeptical at first, thinking Naruto might not be fully prepared for raising a child. But when he sees how much Naruto cares, he would be more accepting. Choji would probably be excited and share his snacks with the little girl right away, showing his warm - heartedness towards Naruto's new family member.
Shikamaru would likely be the voice of reason. He would tell Naruto to think things through clearly and help him come up with strategies for dealing with the new situation. Choji might bring over some food to help Naruto out, as he knows how difficult it can be to take care of a child. Ino would be more interested in the child's appearance and would offer to help Naruto with things like shopping for the child's clothes.
Sakura might tease Naruto about it a little. She'd probably think it's a bit strange that he's interested in something so different from their own world. But she'd also be curious to know what it's all about.
When Naruto's friends see him with the Spartan armor, it would cause a stir. They would all gather around, asking questions. Some would be excited about the new possibilities it presented, while others might be worried about where it came from and if it was dangerous. Naruto would have to explain what he knew about it, and they would all start brainstorming about how they could use it in their future battles or missions. They might also have to deal with any jealousy or envy that could arise if the armor seemed to give Naruto an unfair advantage.
Sasuke, who has his own complex relationship with Naruto, would probably be in denial at first. He's seen Naruto as this strong - willed person, and the idea of him having schizophrenia would be hard to accept. But as time goes on, he would become more protective. He might train Naruto in ways to control his mind during the episodes, using his own experiences of mental discipline. As for Kakashi, he would be empathetic. He has his own traumas, and he would do his best to support Naruto, maybe sharing his own stories of dealing with difficult mental states.
Shikamaru, being the smart and observant one, would analyze the situation thoroughly. He would probably warn Naruto about the potential political pitfalls and how to navigate them. He might also offer some strategic advice on how to handle the relationship aspect, like how to communicate effectively with his new partner in the political marriage so that Naruto doesn't get caught up in unnecessary drama or power plays.
