Maybe the fanfiction could begin with Hinata being bullied during a village festival. The bullies are jealous of her because of her connection to the Hyuga clan. Naruto is enjoying the festival when he hears Hinata's cries for help. He races to her side. He first tries to reason with the bullies, but when they don't listen, he shows off a little bit of his new jutsu. This makes the bullies flee. Hinata is embarrassed but also very grateful. Naruto then stays with her for the rest of the festival, making sure she has a good time and boosting her self - esteem.
The plot could start with Hinata being alone in a secluded part of the village and the bullies spotting her. They start to tease her about her family or her lack of confidence. Naruto, who has a strong sense of justice, comes across the scene. He uses his skills and his reputation as a hero to scare the bullies away. After that, Hinata and Naruto have a moment where Hinata thanks Naruto, and Naruto encourages her to be more assertive.
Once upon a time, Hinata was being bullied near the training grounds. The bullies were taunting her about her shy nature. Just as they were about to get physical, Naruto showed up. He remembered all the times Hinata had been kind to him. 'You guys think it's cool to pick on someone smaller?' Naruto asked. The bullies tried to act tough but Naruto's presence was too much for them. He then turned to Hinata, 'Don't let them get to you. You're strong, Hinata.' And from that day on, Hinata felt a little braver knowing Naruto had her back.
Well, it could be that Naruto witnesses Sasuke being bullied, like maybe some villagers are taunting her about her clan. Naruto, being the hero he is, jumps in and scares the bullies away. Then he takes Sasuke to a quiet place and they have a heart - to - heart about how they both feel like outcasts in some ways.
Well, perhaps Naruto has been observing Ino for a while and when he finally sees the school bullies picking on her, he steps in without hesitation. He might use his Uzumaki charm to first try and talk the bullies down. But if that doesn't work, he'd be ready to fight. His Rasengan might not be necessary but his basic ninja skills would be enough to send those bullies running. And this event could be the start of a closer friendship between Naruto and Ino.
A plot could be that there's a tournament - like situation where Neji and Hinata are pitted against each other, but Neji goes too far. Naruto, who has feelings for Hinata (even if he hasn't fully realized it yet), jumps into the fray. He uses his shadow clones to confuse Neji and then uses his Rasenshuriken in a non - lethal way to stop Neji. This not only saves Hinata but also starts a new chapter in their relationships, with Naruto becoming more aware of his feelings for Hinata and Neji starting to question his own actions and beliefs.
A plot twist might be that the bullies turn out to be working for someone who wants to test Naruto's resolve. So, after saving Ino, Naruto discovers this and has to be on guard against further attacks. Also, it could be that Ino was faking being in trouble to test Naruto's friendship, but then real bullies show up and Naruto still has to save her for real. This would add an interesting layer to their relationship.
Well, one possibility could be that Sakura is about to do something harmful to Naruto out of jealousy or a misunderstanding. Hinata, who has a deep love for Naruto, senses the danger and steps in. She might use her Byakugan to detect Sakura's intentions early. Then, she could use her Gentle Fist techniques to stop Sakura without seriously hurting her. This would lead to Naruto realizing Hinata's true feelings for him more deeply and perhaps start to see her in a new light.
One possible plot twist could be that Orochimaru was actually being controlled by a greater evil, and Naruto has to not only save Hinata but also deal with this hidden threat. Maybe Orochimaru was forced to target Hinata to draw Naruto out for this other entity's purposes.
Well, after Naruto saves the girl, she might become his friend. They could start training together, and she could learn some of Naruto's ninja skills. This would make her stronger and more confident, so she could stand up to the bullies on her own in the future.
Well, Naruto might discover some new Orochimaru's plan during the rescue. Maybe Orochimaru was trying to use Hinata to get some information about the Byakugan. After saving Hinata, Naruto could go on a mission to stop Orochimaru from achieving this goal with the help of his friends like Sasuke and Sakura.
Maybe the story shows Harry coming across Luna being bullied in a secluded part of Hogwarts. He steps in bravely, using his reputation as the 'Boy Who Lived' to intimidate the bullies into leaving Luna alone. He might also comfort Luna afterwards and form a stronger bond with her.
