They could also practice their ninja skills together. Naruto is known for his hard - working attitude when it comes to getting stronger. His sister could join him in training, and they could teach each other new techniques. Naruto might show her his Rasengan, and she could teach him some unique jutsu she has learned or developed on her own.
Perhaps they would explore their family secrets. Since Naruto has always been in the dark about some aspects of his family, with just the two of them, they could start looking into old family mementos or stories that might lead to uncovering hidden truths.
In this fanfiction, Naruto could be visited by the spirit of his father, Minato. Minato could offer some words of wisdom and comfort to Naruto on his birthday. They might have a heart - to - heart conversation about Naruto's growth as a ninja and his future in the village.
They would probably start by catching up. Naruto has a lot of adventures, and his sister would be eager to hear about them. They would talk and laugh, reminiscing about old times.
They could lose their home. If the betrayal is by the village, they would no longer be welcome there. They'd have to find a new place to live, which could be a difficult task as they are being hunted. They might end up in a hidden, desolate place where they have to start from scratch, building shelter and finding food.
In a fanfic, if Naruto is left behind by his team, he might first feel a sense of abandonment. He could then use this as motivation to train harder on his own. For example, he might discover new jutsu or ways to improve his skills. He could also cross paths with other characters who help him grow in different ways, like an old hermit who teaches him some unique wisdom.
In this fanfiction scenario, Naruto could potentially use new and untested jutsu. He might draw on the power of his nine - tailed fox in a completely different way. Maybe he'd combine Sage Mode with some secret Uzumaki clan technique he discovers during the fight.
In this fanfiction, Naruto may find himself in a situation where he's being hounded by people for various reasons - some for help, some for his power. He simply wants to be left alone to live a normal life. So he might start to avoid the village and the people in it, seeking refuge in a secluded place. There, he could explore his own thoughts and feelings more deeply, perhaps even learning new skills or abilities on his own, away from the watchful eyes of his friends and the village.
It's possible that there is some sort of conflict at first. For example, they may have had a misunderstanding in the past that led to a rift between them. But as they meet, they start to clear up the confusion and gradually repair their relationship. This could involve apologies, explanations, and a newfound understanding of each other.
In the fanfiction, Goku might be initially shocked to meet his sister. He could then start to feel a strong sense of protectiveness towards her. Maybe they would train together to become stronger.
In such a fanfiction, Naruto might finally get the father - son relationship he always craved. Minato could train Naruto personally, passing on his powerful jutsu and wisdom. Naruto would grow up with a strong sense of family and might become an even more confident ninja at a younger age.
In this fanfic situation, Naruto's determination would be a key factor. He has a never - give - up attitude. So when the assassin attacks, he'd be in full combat mode. His sister might be a target because of Naruto's status. If she's a ninja too, they could perform some combination attacks. But if she's not, Naruto would have to be extra careful to keep her safe from the assassin's lethal moves.
