His relationship with the villagers would be a mixed bag. Some of the younger villagers who look up to Naruto as a hero would be in awe of his new ability. They'd see it as just another amazing thing he can do. But the older villagers, especially those who remember the destruction caused by the Nine - Tails in the past, might be afraid. They might start to distance themselves from Naruto again, fearing that he could lose control of the fox he can now summon. But Naruto, being Naruto, would probably try his best to show them that he can handle it and use it for good.
The new summoning contract could also have an impact on Naruto's relationship with the village elders. They might be suspicious of this new power source and keep a closer eye on Naruto. However, Naruto's friends like Shikamaru would likely be more laid - back about it. Shikamaru would probably offer his strategic mind to help Naruto figure out the best ways to use the summoned creatures. And Naruto's bond with Hinata could become stronger as she stands by his side during his journey to master the new summoning contract.
If the summoning contract has a connection to a particular family in the village, it could improve Naruto's standing with that family. He might be invited to their family events and be seen as an honorary member. However, if the contract is related to a dark or secretive part of the village's past, some villagers might be afraid of Naruto and try to distance themselves from him.
Some characters might be more distrustful of him. In the Naruto world, people can be wary of those with strange or different natures. His half - fox side could make some characters see him as more of a threat or an outcast.
Well, it might make his relationships more complex. His friends could be both curious and a bit wary at first. For example, Sasuke might see him as even more of an oddity, which could either drive them further apart or make Sasuke more protective in a strange way. Sakura might be more motherly towards him, trying to take care of him because of his new features.
His relationship with his sensei, like Kakashi, could become more complex. Kakashi would feel guilty for not being able to protect Naruto from the experiments. And Naruto might start to question Kakashi's ability to keep him safe. This could lead to a strain in their relationship at first, but later they could grow closer as Kakashi helps Naruto recover from the trauma of the experiments.
It could improve his relationship with Sasuke. Since Chidori was Sasuke's signature move for a long time, Naruto learning it might show Sasuke that Naruto respects his skills and is willing to incorporate them into his own fighting style. This could lead to a more positive and equal relationship between them. Also, Kakashi might see Naruto in a new light. He trained Sasuke in Chidori, and seeing Naruto master it too could make him realize Naruto's determination and growth even more.
With his friends in Konoha, they would be worried and perhaps a bit afraid. They know Orochimaru's reputation as a villain. Naruto's friends like Shikamaru might start to keep a closer eye on him, which Naruto could resent. He would feel like they don't trust him anymore, and this could strain their friendships.
It could change his relationship with his enemies too. Enemies might be more hesitant to attack him, not knowing what the mouths on his hands can do. Some might be so freaked out that they avoid him altogether. His relationships with his sensei, like Jiraiya, would be interesting. Jiraiya would likely be excited to study this new phenomenon and help Naruto figure out how to use it to his advantage. And Naruto's new 'hand - mouths' could also bring him closer to some characters who are interested in the strange and unusual in the ninja world.
His relationship with Sasuke might change. Sasuke could see Naruto's new power as a challenge or something to envy. It might also make Sakura more attracted to Naruto because of his increased strength.
It would likely strengthen his relationship with Kakashi. Kakashi, being Naruto's teacher, would be intrigued by this new power and help Naruto train and master it. His respect for Naruto would grow as he sees Naruto handle such a powerful and unique summon. With Sasuke, it could be a source of both envy and a reason for him to re - evaluate Naruto. Sasuke might initially be jealous of Naruto's new power but later realize that they need to work together, especially if the dragon summon is crucial in fighting a common enemy. As for his friends like Shikamaru and Choji, they would be in awe of Naruto's dragon and it would make them more eager to fight alongside him, seeing him as an even greater asset in battles.
