Neji might gain a significant boost in power. Without the seal suppressing him, his chakra flow could become more natural and stronger. He could potentially unlock new abilities or improve his existing ones, like his Gentle Fist technique becoming even more potent.
In fanfiction, Naruto might remove the curse seal through intense training. He could focus his chakra in a new way to counteract the dark energy of the curse seal. For example, he might use Sage Mode training to purify his chakra system and gradually force out the curse seal's influence.
In many fanfictions, Naruto might use his unique chakra, perhaps enhanced by his Uzumaki heritage or the Nine - Tails' power. His strong will and connection to his friends could also play a role, allowing him to find a way to break the seal through sheer determination and his belief in Neji's potential.
One possible plot could be that Naruto, as a seal master, discovers a new and dangerous seal. Anko, being curious and fearless, joins him in his investigation. They might face various challenges, like enemy ninjas who want to use the seal for evil. Along the way, Naruto could use his seal - making skills to protect them and Anko would use her combat skills to fight off attackers.
Kakashi could also be of assistance. With his Sharingan, he might be able to analyze the seal and figure out its weak points. Then he could guide Naruto on how to target those weak points and break the seal.
Fanfiction often takes characters and gives them new relationships. Regarding Naruto being Anko's brother, it depends on the specific fanfiction. Some authors might see an interesting plot point in making them siblings. For example, they could write a story where Naruto's positive attitude affects Anko in a new way because of their brother - sister bond. Or perhaps they explore how their shared heritage (if fabricated in the fanfic) influences their ninja paths. But it's important to note that this is not the case in the original Naruto anime and manga.
Their relationship could start with respect. Naruto respects Anko's skills and her no - nonsense attitude. Anko, in turn, respects Naruto's determination. As they interact more, they start to share their past traumas. Naruto tells Anko about his loneliness as a child, and Anko opens up about her experiences. This mutual understanding leads to a deeper emotional connection and eventually love, which results in marriage.
At first, it might be rocky. Naruto's carefree nature could clash with Anko's more serious side. But as they start to communicate more, they find common ground in their love for the village. They would learn to respect each other's skills and abilities, and that would form the foundation of their relationship.
Their relationship could start off as comrades. Naruto, being focused on his seal work, might initially see Anko as just another helper. But as they spend more time together, he starts to notice her unique skills and determination. Anko, for her part, would be impressed by Naruto's seal - making abilities. Slowly, they could develop a friendship based on mutual respect.
Anko's a bit of a rebel in some ways. This could encourage Naruto to think outside the box when it comes to ninja tactics. He wouldn't be so bound by the traditional ways. For example, he might come up with new ways to combine his Rasengan with other jutsu based on Anko's unorthodox thinking. Also, her somewhat edgy personality could make Naruto more street - smart and less naive in the ninja world.
