His confidence would likely increase. Successfully saving Kin in a difficult situation would reinforce his belief in his own abilities. He might also become more diplomatic as he might have to deal with different parties involved in Kin's situation, whether it's her former allies or the ones who put her in danger. Naruto would learn to balance his head - strong nature with more tactful approaches. For example, if Kin was caught in a cross - fire between two warring factions, Naruto would have to negotiate with both sides to ensure her safety.
His character development could be shown through his decision to save Kin and Tayuya. At first, Naruto might be hesitant as they were once enemies. But his growth in understanding that everyone can change makes him act. He becomes more empathetic and less judgmental, which is a big step in his character development.
Naruto's character development could be shown through his increased sense of responsibility. In saving Ayame, he realizes that he has to protect not only his friends but also the people in the village who are important to his friends. For example, Ayame is Teuchi's daughter, and by saving her, Naruto shows that he values the relationships of those close to him more deeply.
His confidence would likely grow. Saving Mikoto, who is an important figure in the ninja world, would make Naruto realize his own capabilities even more. He would feel more like a true hero and protector of the village.
His character might develop in terms of his understanding of family. Since Hinata's mom is part of a traditional and complex family like the Hyuga clan, Naruto would have to navigate through their customs and politics to save her. This could make him more empathetic towards family values and the importance of lineage, which is different from his own upbringing as an orphan.
Naruto might become more confident earlier. With a brother by his side, he would have someone to rely on and confide in from the start. This could make him less of an outcast in his own mind and more willing to open up to others in the village.
At first, Naruto might be a bit confused and even scared of his new adamantium claws. He's used to his normal ninja skills and this sudden change would be a big shock. But as he starts to realize the potential of the claws, he would become more confident. His character could develop in a way that he becomes more of a close - range fighter in addition to his long - range ninjutsu. This would also affect his relationships, as his friends and enemies would see him in a new light.
The plot could start with the discovery of the bone welder child's plight. Naruto might find the child while on a journey. Then, there would be a race against time to save the child from the antagonists. After saving the child, Naruto would have to deal with the consequences of his actions, like how to keep the child safe in a world full of threats.
His sense of family would be stronger. Naruto has always longed for family, and having an older brother would fulfill that to some extent. This could make him more empathetic towards others who are also missing family members. He might also be more cautious in battles, as he wouldn't want to let his brother down.
Kin Tsuchi is an interesting character to explore in Naruto fanfiction. In the original Naruto series, she was a member of the Sound Four. In fanfiction, she can be developed in various ways. Some fanfictions might focus on her backstory, perhaps delving into her life before joining Orochimaru. Others could explore her relationships with other characters, like how she might interact with Naruto and his friends if she had a change of heart.
His self - confidence would be severely damaged. He might not believe in his own abilities as a ninja. For example, when facing challenges, he would be more likely to give up easily compared to the Naruto in the original series.
