Yes, there are quite a few. You can check out some fanfiction websites like Archive of Our Own. Just search for 'toneri x hinata' in their search bar, and you'll likely find a variety of stories with different plotlines, from romantic adventures to more emotional and character - driven tales.
Common themes include the discovery of new emotions. Toneri, who has his own set of values and experiences, and Hinata, with her kind heart, often find themselves in situations where they learn about love in a different way. Also, there's the theme of redemption in some cases. Toneri might be portrayed as someone who is trying to make up for his past actions through his relationship with Hinata. Additionally, the idea of cultural exchange between their two different existences can be a theme as well. In these fanfictions, writers play with the idea of how their different cultures interact and influence their relationship.
A plot could involve Toneri and Hinata being forced to work together to stop an ancient evil that threatens both of their homes. As they train and strategize, they find themselves drawn to each other. Their relationship could be a slow - burn one, with lots of moments of hesitation and then finally realizing their true feelings for one another.
In a Toneri and Hinata married fanfiction, their life could be filled with unique cultural blends. Toneri, with his otherworldly heritage, might introduce Hinata to new forms of art and architecture from his home. Hinata, in turn, would bring the warmth of the Hyuga clan and Konoha. They could have children who inherit both their unique abilities. For example, a child might have Hinata's Byakugan along with some of Toneri's moon - related powers. Their relationship would also likely face challenges as they come from different worlds, but their love would help them overcome those obstacles.
Their relationship could develop gradually. At first, there might be some misunderstandings due to their different backgrounds. But as they spend more time together, they'd start to appreciate each other's qualities. Toneri would be drawn to Hinata's kindness and determination, while Hinata would see the good in Toneri beneath his somewhat aloof exterior.
A Hinata leaves Naruto fanfiction could also focus on Hinata leaving to protect Naruto. For example, an enemy might be targeting Naruto and Hinata decides to lead the enemy away from him. This would show her selfless and protective nature. She could then face many challenges on her own while Naruto is left wondering where she went.
Naruto would probably be shocked at first. He might not have expected Hinata to leave him for Kiba. He could be angry at himself for not noticing Hinata's unhappiness sooner.
First, know the characters well. Toneri is a complex character with his own motives and backstory, and Hinata is known for her kindness and determination. Make sure their personalities are consistent. For example, Hinata might show her caring nature towards Toneri in a way that is unique to her. Also, create a vivid setting, whether it's in Toneri's realm or some new place where they meet.
One common theme is redemption. Since Toneri had some rather villainous actions in the original Naruto story, many fanfics focus on him making amends and becoming a better person. For example, he might try to repair the damage he caused to the ninja world.
In such a fanfiction, the plot could involve Hinata feeling unappreciated by Naruto. Maybe Naruto is too focused on his ninja dreams and ignores Hinata's feelings. Kiba, on the other hand, might have been there for Hinata during her low moments, showing her kindness and understanding that Naruto didn't. So, Hinata decides to leave Naruto for Kiba.
