Naruto's character would likely become more nurturing. Since he had to grow up alone for the most part, taking care of his siblings would bring out a softer side of him. He'd learn patience as he deals with their problems and mistakes. Also, he'd probably become more family - oriented and might start seeing the importance of family in a different light than he did before.
In this fanfiction, Naruto's character development would be quite significant. He'd start to understand the sacrifices his parents made for him more deeply. His experience of raising his siblings would make him more empathetic towards others. He'd also become a better leader figure for his siblings, guiding them through the difficulties of being a ninja. This new role would force him to mature faster and he'd have to make wiser decisions not just for himself, but for his siblings as well.
His development would be a tug - of - war between Danzo's influence and his own innate goodness. On one hand, Danzo could instill in him a sense of loyalty to the village at all costs. On the other hand, Naruto's natural desire to make friends and bring people together would constantly fight against that. So, his character might be a complex blend of secrecy and warmth.

Naruto would likely be more refined in his behavior. With Tsunade as a mother figure, he'd be exposed to more formalities of the village leadership. He might be less of a prankster as he'd be under Tsunade's watchful eye. Tsunade's no - nonsense attitude would rub off on him.
Naruto would be more confident earlier. With Minato around, he wouldn't have to face the same level of loneliness and ostracism. So, he'd be more outgoing and less likely to act out for attention. He'd also have better control of his powers from the start, as Minato could train him properly. His fighting style would be more refined, combining Minato's speed and strategic thinking with his own natural abilities.

Naruto would likely become more self - reliant. Without his kind around, he can't rely on the traditional support system of his clan. So he has to figure things out on his own, which would make him grow up faster in some ways.

He'd no longer take loyalty for granted and would be more cautious in his relationships. As he overcomes obstacles, he'd develop a new sense of identity that is not tied to his family's expectations.
