Naruto's character could develop a new sense of loyalty. In the mafia world, loyalty is often a matter of life and death. He'd learn to trust Sakura even more deeply as they are in a dangerous and unfamiliar environment. His ninja skills would also evolve to be more adaptable to the urban and underhanded tactics of the mafia. Sakura would develop a tougher exterior. She'd be dealing with some really bad people, and she can't afford to show weakness. Her medical ninjutsu might also take on a new form, like using it to interrogate or manipulate mafia members who are injured. This would make her a more well - rounded and formidable character in this unique setting.
Sakura might become more confident in her own abilities. In high school, she's exposed to different ideas and people like Deidara. His wild and free - spirited approach to art could make her less afraid to take risks in her own work. For Deidara, being around Sakura could make him more empathetic. He'd have to learn to work with someone who has a different mindset, which could make him more understanding of others in general.
Naruto would likely develop a more serious side. He's used to chasing after Sakura's love in a more light - hearted way, but in a forced marriage, he'd have to step up and be more responsible for her well - being. Sakura would become more understanding of Naruto. She might start to see past her long - held feelings for Sasuke and notice Naruto's true qualities like his loyalty and selflessness. Their relationship would be a journey of self - discovery for both of them.
If Naruto had Saiyan heritage, his character would develop with a new sense of pride. Saiyans are known for their warrior spirit, and Naruto might become more focused on proving himself not just as a ninja but as a Saiyan - ninja hybrid. He could be more reckless in battle, relying on his newfound strength, which would force Sakura to be more of a voice of reason. Sakura, on the other hand, might develop a bit of envy if Naruto gets all these cool Saiyan powers at first. But eventually, she could use it as motivation to train harder and develop her own unique skills.
Naruto would likely become more confident in his relationships. He has always been a bit insecure about his place with Sakura and Sasuke. In this fanfiction, he might finally feel like he truly belongs with them. Sakura could develop into a more understanding and inclusive character. She would have to learn to accept and embrace this new dynamic with both Naruto and Sasuke. Sasuke, on the other hand, would probably soften up a lot more. His cold exterior would melt as he becomes part of this unique relationship, learning to trust and rely on Naruto and Sakura in ways he never thought possible.
In a high - school setting, Sakura would probably be very popular due to her kind heart and strong will. She'd be involved in various extracurricular activities. Shikamaru would be the type to avoid the spotlight, but his intelligence would not go unnoticed. As they interact more, Sakura could help Shikamaru come out of his shell a bit. He could, in turn, teach her to be more patient and think things through more carefully, which would further develop their characters.
Naruto's character might develop by becoming more aware of his feelings for Sakura earlier in the time - travel scenario. He could become more confident in expressing his love. Sakura, on the other hand, might develop a deeper understanding of Naruto's past struggles and grow to love him even more. For example, if they travel back to his early days at the academy, she could see how lonely he was and be more empathetic.
Naruto in the mafia setting could still retain his optimistic and determined nature. He might see the mafia as a way to protect the people he cares about in a corrupt world. His loud and boisterous personality could be toned down a bit to fit the more secretive mafia life, but he'd still be the one to inspire hope among his comrades.
In a mermaid setting, their relationship might start slowly. Sasuke could be initially hesitant as he is new to the mermaid world. Sakura, being more familiar, would help him. As time passes, they would go on adventures together, exploring the underwater caves and hidden treasures. This shared exploration would bring them closer and their relationship would gradually develop into a deep love.
In this fanfiction, the relationship between Naruto and Sakura could develop in a rather unexpected way. Maybe they start off on the wrong foot, constantly arguing about little things like who does the chores or how to decorate their living place. But as they face external threats together, they realize that they are stronger as a team. This realization makes them more understanding and patient with each other. Eventually, they start to appreciate each other's qualities. Naruto admires Sakura's strength and kindness, and Sakura respects Naruto's courage and leadership. This mutual admiration then blossoms into a romantic relationship.
The storyline could develop with Naruto initially being in shock. He might then go on a journey of self - discovery to figure out what went wrong. Meanwhile, Sakura might face consequences from the village for her actions.
