Well, Naruto would probably be a very energetic and determined person in real life. He might be into martial arts or some kind of extreme sport, constantly challenging himself. And he'd surely be the center of attention with his boisterous personality. He could also be a great motivator for those around him, just like in the anime where he inspired his friends.
In the actual Naruto franchise, Naruto Uzumaki is not a singer. He is a shinobi with a strong will and a determination to protect his village. The idea of him being a singer comes from fan - created stories (fanfic). While these can be fun and imaginative, they deviate from the established Naruto lore. Fanfics often explore alternative scenarios for characters, but in reality, Naruto's identity is firmly rooted in his ninja - like qualities.
If we consider Naruto's abilities in real life, his ability to run up walls and on water might be related to some sort of anti - gravity or super - balance technology. He could use these skills in rescue operations, like running up the side of a burning building to save people. His chakra control could also be seen as a form of extreme mental and physical discipline, allowing him to perform feats that seem impossible to others.
Well, Naruto in real life might be that overly energetic and positive guy. He'd probably be the type who's always trying to cheer people up and is super determined in achieving his goals, like in the series. He could be into some kind of extreme sports or activities that require a lot of perseverance. Sasuke would be the brooding and mysterious type. He might be really good at martial arts or some form of self - defense, and he'd keep to himself a lot, but still have a small group of close friends who understand his past traumas.
If Naruto was a singer in real life, he'd probably have a very energetic and passionate style. His songs might be about his dreams and the challenges he's overcome, just like his ninja journey. He could also use his signature orange jumpsuit as part of his stage costume for a unique look.
For Naruto and Sasuke, their relationship might be less intense in some ways. Instead of the whole 'rival - turned - friend - who - still - has - some - issues' thing, they could be more like normal friends who compete in healthy ways, like in sports or academic achievements. Sakura might be more of a mediator between them, instead of being so caught up in her feelings for Sasuke. She could use her intelligence to keep their friendship in check.
In a real - life Naruto fanfiction, Naruto might be an environmental activist. He'd use his speed and energy to clean up parks and natural areas quickly. His 'ninja way' would be applied to his environmental efforts, believing that every small action counts. He'd inspire others to take care of the planet, just as he inspired his friends in the anime to be better versions of themselves.
One idea could be Naruto living in a modern city and trying to find a job. He might use his ninja skills in unexpected ways, like using his speed to be a delivery person. Another could be Naruto going to a normal school and having to deal with bullies, but then using his ninja training to stand up for himself and others.
One way is through the character's growth. Just like in real life, Naruto in this fanfiction could face setbacks in the 'game' world. For example, he might lose battles and have to learn from his mistakes. This can teach readers about perseverance and the importance of learning from failure.
