One thing Hinata could teach Naruto is how to better understand and control his chakra flow. Hinata has been trained in chakra control from a young age as part of the Hyuga training. Naruto, on the other hand, has a large amount of chakra but sometimes lacks finesse in its use. With Hinata's guidance, he could enhance his chakra control skills, which would make his jutsu more efficient and powerful.
Hinata might teach Naruto about patience. Naruto is often impulsive, while Hinata is known for her quiet patience. By learning from her, Naruto could improve his decision - making in battles and in his daily life, becoming more composed and strategic.
In fanfiction, Hinata could teach Naruto about the Hyuga clan's gentle fist style. Since Naruto mainly focuses on his own powerful and straightforward combat techniques, Hinata's more refined and precise style could be a new area of learning for him.
Hinata could teach Naruto about family values. Hinata comes from a traditional and close - knit family in the Hyuga clan. Naruto, who grew up without his parents, could learn a lot about the importance of family bonds, traditions, and the support that a family can offer. This could help Naruto in his relationships with his friends and his future family.
Perhaps in the fanfiction, there's a new threat to the village that requires special skills to defeat. Naruto's rasengan, Hinata's gentle fist, and Akamaru's ability to transform into different forms could be combined in unique ways. They might have to train together to master these new combined techniques. For example, Hinata could use her Byakugan to find the weak points of the enemy, Naruto could attack with the rasengan guided by Hinata, and Akamaru could provide a distraction or additional support.
A simple plot could be that Hinata gets injured while on a mission, and Naruto takes it upon himself to nurse her back to health. During this time, they have long conversations and get to know each other on a deeper level, leading to the start of their romantic relationship.
There are quite a few things. For one, he could teach past Naruto about the deeper secrets of the Uzumaki clan. Since Future Naruto has explored more about his heritage. He could also give tips on handling the Kyuubi's chakra more smoothly. Maybe some new jutsu combinations that he discovered over the years. And not to forget, how to better read an opponent's moves during a fight, which is a skill he would have refined over time.
One possible reason could be a huge misunderstanding. Maybe he thought Hinata did something really bad to his friends, like unknowingly leading the enemy to them. Without knowing the truth, his hot - headed nature made him lash out.
Goku might teach Naruto about the concept of Super Saiyan forms. Although Naruto doesn't have Saiyan blood, he could learn about the idea of unlocking different power levels through intense emotions and training. For example, Naruto could find a way to apply the idea of Super Saiyan rage - like power - ups when he's in a really tough battle and needs that extra boost.
In this fanfiction, perhaps Hinata and Naruto are living together and learning more about each other on a deeper level. Hinata could be teaching Naruto some of the traditional Hyuga clan techniques, while Naruto shows Hinata some of his unique jutsu. Their living situation might also involve a lot of visits from their friends like Sakura and Sasuke, creating some really fun and heart - warming group dynamics.
In the fanfiction, it could be that Hinata is already proficient in kenjutsu. She then teaches Naruto some of the basics. As Naruto learns, they start to have a better understanding of each other's fighting styles. This could lead to them working together more effectively in future battles and also in their relationship development.
In a fanfiction, they could be involved in a race. Naruto's speed, Sasuke's sharingan - enhanced perception, and Hinata's byakugan - aided navigation could all play a part. Maybe they start off competing against each other but then realize that there's an outside threat during the race. So they put aside their differences and work together to overcome the threat, forging a stronger bond in the process.
The fanfiction could show how their relationship deepens during the pregnancy. They could have more quiet, intimate moments together, like sitting on the porch at sunset and talking about their hopes for their child. Hinata could share her dreams of their child growing up strong and kind, like Naruto.
