Well, in some fanfictions, when Naruto sees Hinata in the waterfall setting, it could be a moment of sudden realization. He might finally notice her in a new light, perhaps seeing her beauty and the depth of her feelings for him more clearly. It could be a turning point where he starts to develop deeper romantic feelings for her.
It might be a symbolic moment. The waterfall could represent the flow of emotions that are about to change between them. Naruto seeing Hinata there could signify that he is now ready to see what's been in front of him all along - Hinata's love for him. It's a way for the fanfiction to build up the relationship in a more romantic and meaningful way.
One common theme is the idea of a secluded and beautiful place (the waterfall) being a site for deepening the relationship between Naruto and Hinata. It gives them a private space away from the chaos of the village.
One possible plot could be that Naruto and Hinata go to the waterfall for a secret training session. Hinata has been struggling with a new jutsu, and Naruto offers to help her. At the waterfall, they face various challenges together, like wild animals and difficult terrains. This not only helps Hinata with her jutsu but also deepens their bond.
There's also a fanfiction titled 'Waterfall Confessions'. In this story, the waterfall serves as a backdrop for Hinata to finally gather the courage to confess her feelings to Naruto. It's a heart - warming read with a lot of emotional depth.
Well, it might be that in the fanfiction, Naruto goes to the frozen waterfall to have a conversation with Kyuubi. They could be discussing Naruto's growth as a ninja and how Kyuubi's power can be better harnessed. The frozen waterfall setting adds a sense of isolation and mystery to the encounter.
A romantic moment could be when Naruto and Hinata are standing by the waterfall. The mist from the falls creates a beautiful backdrop. Naruto gently takes Hinata's hand and tells her how much she means to him.
In some Naruto fanfictions, Hinata could potentially be portrayed as a 'weapon' in a very metaphorical sense. For example, her Byakugan abilities might be exploited in unique ways that make her seem like a strategic weapon for a side or a cause. But in the canon Naruto story, she is a character with her own agency and not really a weapon.
One great source for Naruto and Hinata fanfiction could be FanFiction.net. You can search for stories specifically focused on their relationship there. There are often new and interesting takes on their story, from how they first fell in love to their married life in the future.
Perhaps in the fanfiction, Hinata wears a micro bikini for a special festival in the Hidden Leaf Village. Naruto is really excited to see her in it. They participate in the festival games together and Hinata's new look makes Naruto see her in a different light, more as a strong and confident woman.
