Kakashi would be quite impressed by Naruto's creativity in using the clone jutsu in such an unorthodox way. He would also be cautious though, knowing that any new and untested jutsu can have unforeseen consequences. His friends from Team 7 would also start to think about how they could incorporate this new form of Naruto's clone into their battle strategies. For example, they could use the black book clone to gather intelligence or as a decoy in a more complex and unexpected way.
His friends would be in shock. Kakashi would take charge of the situation. He would gather all the information about what Naruto was doing before he disappeared. Naruto's friends like Choji and Ino would use their respective skills to help in the search. Ino could try to use her mind - reading jutsu on people who were around Naruto before he disappeared. They would all be determined to find Naruto because he is an important part of their team and the village.
Sakura might be really surprised at first. She could offer to help Naruto with his girl disguise, teaching him things like how to do his hair or choose the right clothes. She might also find it a bit funny but would be supportive in the end, seeing it as part of a mission. Sasuke, on the other hand, might be a bit more aloof. He would probably just raise an eyebrow at Naruto's new look but wouldn't make a big fuss about it as long as it was for a good reason.
The Pokémon in the fanfiction would have a range of reactions. Some of the more friendly Pokémon might be curious and approach Naruto - as - Latias, thinking he's a lost or strange - looking Latias. However, the more territorial or aggressive Pokémon could see him as an intruder and attack. Naruto would then have to use his ninja skills as well as the abilities he has from the Latias form to defend himself and try to communicate that he means no harm.
His friends would be shocked at first. Sasuke, for example, might see it as a sign of weakness on Naruto's part, that he let Minato do this to him. Sakura would be worried about Naruto's well - being and would try to find a way to reverse the process. Shikamaru would be thinking about the long - term consequences for the village and for Naruto's relationships. Overall, they would be very concerned and try to get Naruto back to his normal self.
Sakura might be a bit surprised at first. She would probably tease Naruto a little about it, but then she'd also be curious to see what's in those fanfics. She might even start reading some herself to see how the fans portray her relationship with Naruto.
If the female clone's actions become more extreme, Naruto would likely become more serious. He has a strong sense of justice and protecting his friends. He wouldn't let her harm anyone. He might try to use his own ninja skills to subdue her and figure out a way to reverse whatever made her this way. He'd also draw on his own experiences of being an outcast and try to reach out to her on an emotional level, hoping to change her yandere ways.
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.
Well, Naruto's friends would be in an uproar. Iruka, who has always been like a father figure to Naruto, would be heartbroken and would not rest until he knew Naruto was safe. The other Konoha ninja would also be affected. Neji, despite his initial coldness towards Naruto, has come to respect him. He would see Orochimaru's actions as a threat to the village and to his friend. Tenten would offer her weapon - related skills to help in any rescue attempt. And Hinata, who has deep feelings for Naruto, would be extremely distraught. She might even try to take on Orochimaru herself in a desperate attempt to save Naruto, regardless of the danger to her own life.
