Shikamaru would likely be lazy about getting involved at first. But if it started to cause a big ruckus in the village or among their group of friends, he'd step in. He'd probably analyze the situation quickly and try to find a logical solution. He might tell Naruto to cool off and Kiba to stop provoking Naruto if that was the case.
One possible reason could be a simple rivalry that has boiled over. Maybe they were competing for the same mission, and Naruto's determination to prove himself got the better of him. He might have seen Kiba as a threat to his goal of becoming Hokage, thinking that if Kiba succeeds in a high - profile mission, it could overshadow his own achievements.
It could also be that Naruto has unspoken feelings for Hinata. So when Kiba steals from her, it's not just about the act of stealing, but also a sort of territorial thing. He feels the need to defend her honor, like a knight in shining armor.
Another great one is 'Naruto and Kiba: The Unlikely Alliance'. In this fanfiction, they are forced to work together in a difficult situation that neither expected. It shows their different skills and how they combine them to overcome challenges, and in the process, their friendship deepens.
There's also 'The Female Ninja and Kiba'. In this fanfiction, a female ninja with unique abilities teams up with Kiba. It delves into how their different personalities complement each other. For example, her calmness balances out Kiba's sometimes over - enthusiastic nature, making for an interesting dynamic.
It could be that Kiba has been involved in something that Naruto considers wrong. For example, if Kiba endangered the safety of the village or their friends, Naruto, being the protector - type, would take action against him. Or perhaps there was a misunderstanding between them. Kiba might have been framed for something, and Naruto, believing the false information, tries to 'destroy' Kiba in the heat of the moment.
Perhaps in the story, there is a competition for a rare ninja item or a special mission opportunity. Kiba, being very competitive, sees Hinata as a threat. He tries to intimidate her by making fun of her skills in a very mean way. Hinata, who is already a bit shy and self - conscious, is deeply hurt by Kiba's actions. Naruto, on the other hand, witnesses this and stands up for Hinata, which then starts a whole new plot development in the fanfiction.
I really like the 'Kiba Naruto Fanfic' titled 'Kiba's New Power'. In this story, Kiba discovers a new and unexpected power within himself, which changes his role in the team. It's exciting to see how he uses this power to help his friends and face the enemies. There's also 'Kiba in the Land of Shadows', which takes Kiba on a journey to a spooky and dangerous land. It's full of action and mystery as he tries to survive and complete his mission there. And don't forget about 'Kiba and Akamaru's Bond Strengthened', which explores the deepening relationship between Kiba and his faithful companion Akamaru.
There are various scenarios that could play out in such a fanfiction. Maybe Naruto was injured during a mission and Kiba stumbles upon him in the forest. Kiba would then likely try to help Naruto, either by getting medical help or using his own skills if he has some knowledge of healing. This could lead to a deeper bond between them as Kiba shows his concern and Naruto is grateful for the assistance.
There's a fanfic called 'Kiba and Naruto: Unlikely Allies'. In this story, they are forced to work together in a situation where they initially don't get along. It's interesting to see how their relationship evolves over time. The author does a good job of capturing their personalities.
