Hinata supports Naruto by being his emotional anchor. When facing the Juubi, Naruto can get caught up in the chaos and danger, but Hinata is there to remind him of his humanity and the things he's fighting for. For example, with a simple look or a kind word, she can calm him down in the heat of battle.
In many fanfictions, Hinata's unwavering belief in Naruto is a huge form of support. Even when others might doubt Naruto's ability to handle the Juubi, Hinata is always there believing in him. This gives Naruto the confidence he needs to keep pushing forward. She might also provide him with physical support, like healing him when he gets injured during battles with the Juubi or sharing her chakra with him when he's running low.
Naruto would support Hinata by being there for her emotionally. He would listen to her concerns and fears about becoming a mother. He'd also be physically present as much as possible, helping her with daily tasks like carrying heavy things.
Often, it develops from Hinata's long - standing admiration for Naruto. In the context of Naruto being an emperor - like figure, Hinata's respect for him grows even more. Naruto, in turn, begins to see Hinata in a new light, realizing her loyalty and strength. This mutual understanding and respect deepen their bond.
In some of these fanfictions, their relationship develops as they gradually remember their past. They start having strange feelings and dreams, which lead them to explore their connection. As they do so, they start to fall in love all over again, just like in their previous lives.
In fanfiction, their relationship often deepens as they face parenting challenges together. They support each other more and become more in tune with each other's feelings.
Fanfiction contributes by exploring different scenarios. For example, it can show them in everyday situations that the original series might not have covered. This gives a more complete view of their relationship.
One popular storyline could be Naruto and Hinata having to face the Juubi together. In this scenario, Naruto's power and Hinata's supportiveness combine. For example, Naruto might be in the front lines fighting the Juubi's brute force while Hinata uses her Byakugan to detect any weak points or incoming attacks from the Juubi. Their love for each other could also be a factor, with Hinata's unwavering belief in Naruto giving him the extra boost he needs to keep going. Another storyline could involve the Juubi somehow affecting Naruto and Hinata's relationship. Maybe the Juubi's presence or its chakra has an influence on Naruto's mind, and Hinata has to fight to bring him back to his true self. This could lead to some really emotional and intense moments between them as Hinata tries to break through whatever hold the Juubi has on Naruto.
In these fanfictions, Hinata often develops more confidence. As Naruto's secretary, she has to interact with many people and handle important tasks. For instance, if she has to give presentations on Naruto's behalf, it forces her out of her shell. This new - found confidence can also affect her relationship with Naruto, as she becomes more assertive in expressing her feelings for him.
In many fanfictions, Hinata calms Naruto with her gentle presence. Just by being there beside him, her quiet and kind nature has a soothing effect on Naruto, who is often so full of energy and impulsiveness. For example, she might hold his hand or give him a soft, understanding look that makes him feel at ease.
Often, Naruto's status as a hero in the fanfiction world plays a big role. The Kumo ninjas might be a bit intimidated by him. He might start by making a grand entrance, shouting out his intentions to save Hinata. His reputation precedes him. Then he uses his Nine - Tails chakra, which gives him a significant power - up. He uses this enhanced power to fight off the Kumo ninjas who are holding Hinata captive and finally saves her.
Often, in these fanfictions, the development of their love is also influenced by the people around them. Their friends might notice Hinata's feelings for Naruto long before he does. And through some gentle nudging or matchmaking attempts by their friends, Naruto starts to consider Hinata in a romantic way. Also, Hinata's family's acceptance of Naruto can play a role. Naruto, who has always craved family, feels a deeper connection to Hinata when he realizes how her family welcomes him.
