Lucy would likely be very worried about Naruto. She might feel abandoned at first, especially if she doesn't know the reason behind his running away. She could also be in danger if Naruto was protecting her from something. Without him around, she would have to fend for herself or rely on other friends or family members.
Well, it could be that Naruto, being the brother of Lucy, ran away perhaps due to some sort of family conflict. Maybe he didn't agree with the way their family was handling things, like their training methods or the expectations placed on them. Another possibility is that he ran away to protect Lucy from some unseen danger. He might have found out something dangerous was coming their way and thought it was better to lead the threat away from her by running off.
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.
One idea could be a crossover where Naruto and Lucy end up in the same world. Maybe they team up to fight a common enemy that threatens both their universes. They could learn from each other's unique abilities, like Naruto's jutsu and Lucy's Celestial Spirit Magic.
Perhaps Naruto's brother could be a long - lost relative from a far - flung part of the ninja world. He could have been separated from Naruto when they were young due to a war or some political intrigue in the ninja clans.
