Sasuke might be initially suspicious. He would question Naruto's motives and the potential danger of such an army. But after seeing how Naruto uses it for good, he might come to accept it.
Sakura would probably be a bit worried at first. She'd be concerned about the safety of the village and the implications of having a robot army. However, if Naruto showed that the robots were under strict control and were being used for positive things like helping with medical emergencies or rebuilding damaged areas, she would likely support it. Also, she might even try to learn about the technology behind the robots to see if she could use it in her medical practice, like using robot assistants in surgeries or for transporting medical supplies more efficiently.
Sakura might be initially shocked. She has always known Naruto as the go - lucky ninja, and the tattoos and piercings would be a big change. She might scold him at first but then come to understand his reasons behind it.
His friends' reactions would be diverse. Naruto's more hot - headed friends like Kiba might be excited about the new firepower the modern army brings. They might want to jump right into using the guns and other weapons. But Naruto's calmer friends like Neji (if he were still alive in the fanfiction) would be more cautious. They would worry about the long - term effects on the ninja world, such as the potential for mass destruction and how it would change the balance of power. And Ino might be interested in how the modern army's communication systems could be used to improve their own ninja intelligence networks.
Perhaps it's for exploration. Naruto is always curious about the world outside. The robots can be sent to explore dangerous or uncharted areas where it might be too risky for humans to go. They can collect information and report back to Naruto.
Sakura would be really happy for them. She has been friends with both Naruto and Ino for a long time. She would probably offer to help Ino during her pregnancy, using her medical skills. Shikamaru might act like he doesn't care much at first, but secretly he would be glad for his friends. He might offer some practical advice about raising a child, like how to deal with the financial aspects or the importance of education. Choji would be excited and would bring over lots of food to make sure Ino and the baby are well - nourished.
Sakura would probably be a bit skeptical at first. She'd worry about how Naruto could take care of another person when he's always so busy with his ninja duties. But once she sees how much Koneko needs a home and how Naruto is committed, she'd warm up to the idea. Sasuke might not show much emotion on the surface, but secretly he'd respect Naruto's decision. Shikamaru would think it's a troublesome situation but would also see the good in Naruto giving Koneko a chance at a better life.
Sasuke would be very suspicious at first. He's always been cautious about Naruto's new powers, and this one, which has the ability to take other people's powers, would make him wonder if Naruto was going to change. Sakura would be worried about the moral implications. She'd try to talk to Naruto about using it for good. Kakashi, on the other hand, would be more understanding. He'd see it as just another power Naruto has to learn to control and would offer his guidance on how to use it responsibly.
His friends would likely be shocked. Shikamaru, for example, would probably be disappointed in Sakura. He might try to comfort Naruto and tell him to think rationally. Choji might be angry on Naruto's behalf and want to confront Sakura. And Sasuke, if he's around, might have a complex reaction. He might feel a strange sense of satisfaction that Naruto is finally seeing Sakura's 'true' side, but also a bit of pity for Naruto.
Sakura might be a bit surprised at first but would quickly support Naruto's choice if she sees that Fem Kami makes him happy. Sasuke would probably be indifferent on the surface but secretly happy for Naruto as long as it doesn't interfere with their own goals. Shikamaru would likely think it's a troublesome situation but would also go along with it as long as Naruto is sure about what he's doing.
Sakura might be a bit worried at first. She's always been concerned about Naruto's safety, and a new weapon like Zabuza's sword could seem dangerous. But she would also trust Naruto's judgment in the end.
Well, Naruto's friends have seen him grow and change in many ways. When they find out he's a Vocaloid fan, some would be supportive right away. Hinata, for example, would be very sweet about it and might even listen to Vocaloid music with him. Lee would see it as another form of passion and energy, much like his own love for training. Tenten might be a bit skeptical but would come around once she sees how happy it makes Naruto. As for Neji, he might be a bit more reserved in his reaction, but he wouldn't be against it as long as it doesn't interfere with Naruto's ninja duties.
