His friends might initially be shocked. For example, Sakura might feel guilty for not noticing sooner. She could try to be more present in Naruto's life, cooking for him or just sitting and talking. Shikamaru, being the perceptive one, could come up with a plan to cheer Naruto up, like organizing a small get - together with just their closest friends.
Well, Sasuke could have a complex reaction. At first, he might not know how to handle it as he's not great with emotions. But then he could use his own experiences of pain and isolation to try and reach out to Naruto. He might tell Naruto that he too has felt lost and alone at times, and that they can get through this together. His friends would overall become more protective of Naruto, making sure he doesn't overwork himself and is taking care of his mental health.
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.
Sasuke would be suspicious at first. He might think Naruto is getting power from a dangerous or untrustworthy source. But once he sees Naruto using the high - tech weaponry for the good of the village, he would start to accept it. Sakura would be worried about Naruto getting in over his head with these new and unknown weapons. She would constantly be checking on him to make sure he's not endangering himself. Kakashi, on the other hand, would be intrigued. He would want to study the weaponry and see how it could be integrated into Konoha's defenses.
If his friends found out, they would all react differently. Isaac might tease him a bit about it, but in a friendly way. Derek, on the other hand, would be more stoic and might wonder if there was something deeper behind Stiles' interest. Stiles would have to defend himself, saying that he just finds the werewolf concept in fanfiction fascinating. His friends would then start to notice little things about Stiles that they hadn't before, like his knowledge of werewolf lore that he's picked up from the fanfiction, and it could change their dynamic in an interesting way.
If their friends found out, Kiba might tease Naruto a little bit, but in a friendly way. He respects Hinata and Naruto, so he'd be okay with it. Ino would be all excited and would start asking Hinata for details. She's always interested in romantic stuff. Lee would be super positive and give Naruto a big thumbs - up, saying something like 'Youthful love is wonderful!'. And Neji, if he were still alive, would be very protective of Hinata at first, but then see how happy Naruto makes her and be supportive.
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.
Well, his friends' reactions would vary greatly. Kakashi, with his calm and collected nature, would likely offer his support while also being a bit amused by the situation. Naruto's closest friends like Choji and Kiba might have a more comical reaction at first, but then step up to be there for him. As for Hinata, if she has feelings for Naruto, she might be a bit hurt at first but then become one of his strongest supporters.
Well, if his friends found out in the fanfiction, it would be a big deal. Percy's friends are used to depending on him in their battles and adventures. Finding out he's a dad would make them re - evaluate their relationships. Leo might crack a joke at first to ease the tension, but then they'd all realize the seriousness of the situation. Some might be concerned about the safety of the child, given the dangerous world they live in. They'd also have to adjust to the fact that Percy now has a new priority in his life, and they'd need to figure out how to support him while still continuing their own quests.
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.
His friends might be really shocked at first. They know Naruto as a ninja, not someone who sings fanfiction. Some might find it hilarious and start teasing him in a friendly way. For example, Shikamaru might say something like 'Only you, Naruto, would come up with something so strange.'
Hermione's friends from Gryffindor would be a mix of disbelief and concern. Neville, for example, would be worried that Draco might be using Hermione in some way. Luna would be more accepting, seeing it as a unique and interesting relationship that defies the norms of the wizarding world. As for Draco's friends from Slytherin, they would also be shocked. Some might see it as a betrayal of Slytherin values, while others might be intrigued by the power dynamics at play between a Muggle - born witch and a pure - blood wizard.
