The village would be in shock at first. They are used to Naruto as a ninja, and suddenly he's a Dragon God. Some would be fearful, worried that he might use his new power against them. But many, especially his friends, would be proud. They would see it as Naruto reaching a new level of power to protect the village even better.
Sakura would probably be a bit skeptical at first. She might worry that Naruto is getting distracted from his ninja duties. But once she sees how passionate he is, she would support him and might even help him with his training regime, using her medical knowledge to make sure he's in top physical condition for racing.
His friends would be very shocked at first. Sasuke, for example, might be suspicious of this new Naruto. But once he realizes that Naruto is still the same at heart, he would start to accept it. Sakura would probably be worried about Naruto's well - being and try to find a way to reverse the change if possible.
Sakura might be a bit confused at first. She's focused on her medical ninja training and Naruto's sudden interest in Lunney seems out of left field. But she would probably be supportive in the end, especially if Naruto could show her how Lunney's ideas could be relevant to their lives. Sasuke, on the other hand, would likely be dismissive. He has his own goals and Naruto's newfangled interest might seem like a distraction to him. However, if Naruto could prove that Lunney's concepts could help in their fight against common enemies, Sasuke might change his tune.
His friends' reactions would be mixed. Naruto's closest friends, like Choji and Ino, would be really worried about him. They'd be sad to see him change into something so different from the Naruto they know. But at the same time, they would also be curious about his new powers. Sasuke, if he's around, might be a bit more aloof at first. He'd see Naruto's transformation as another sign of Naruto's growth and might even be a bit jealous that Naruto has gained these new and potentially powerful abilities.
Sasuke would probably be initially shocked. But then he'd be all about finding a solution. He might even sacrifice some of his own power to try and save Naruto. Sakura would be horrified and would immediately start researching any medical jutsu that could reverse the process.
His friends would be really confused at first. Sakura might try to use her medical ninjutsu to figure out what's wrong with him. Sasuke would be more reserved but also determined to find a way to turn Naruto back. Shikamaru would probably start thinking about all the possible reasons and solutions right away.
Kakashi would be very concerned as well. He would approach Naruto in a more calm and collected way compared to Sasuke and Sakura. He would try to understand Naruto's reasons for becoming a fan. Kakashi would then use his own experiences and wisdom to show Naruto the darker side of Doflamingo that he might be overlooking, hoping to bring Naruto back to his normal self.
His friends like Shikamaru would find it strange at first. Shikamaru is a practical thinker and yokai seem like something out of a fairy tale to him. However, if Naruto showed him some practical applications of yokai knowledge, like using yokai - inspired strategies in battles, Shikamaru might start to respect Naruto's new interest. Choji would probably be more open - minded. He'd be curious to hear Naruto's stories about yokai and might even ask if there are any yokai - related food or things to eat in the yokai world.
The village would be in shock at first. Naruto was a beloved figure, so his death would be a great loss. But they would also have to accept Sasuke as Hokage. Some might be hesitant as Sasuke has a dark past. However, his actions in protecting the village in the past, like during the Fourth Shinobi War, would give him some credibility. The older generation who knew Sasuke from his early days might be more accepting, while the younger ones might be a bit scared of his cold exterior.
Sakura would be extremely proud. She has seen Naruto grow from a clumsy kid to a potential Hokage. She'd probably be right by his side, offering her medical skills to support him and also giving him advice when it comes to dealing with the more diplomatic aspects of being Hokage. Shikamaru, on the other hand, would be a bit more reserved in his reaction. He'd recognize the huge responsibility Naruto has taken on and would be ready to offer his strategic mind to help Naruto make important decisions.
