He could try to learn spells the way he learned ninja techniques, with a lot of physical training. And his strong sense of loyalty and friendship from the Naruto series would fit right in with the values in the Harry Potter world.
It could be really interesting. Naruto might be a student at Hogwarts, using his ninja skills in the wizarding world. He could use his chakra like magic and have adventures with Harry Potter and his friends. For example, he might use his shadow clone jutsu to help in a big wizarding battle, or his speed to outrun dark wizards. It would be a cool crossover of two very different universes.

This mentor could teach him both magic and ninja skills. His relationships with Ron and Hermione might be different too. Instead of just relying on magic for solutions, he might use his ninja - inspired physical abilities. And the magic system could potentially be merged with chakra concepts from Naruto, creating a whole new way of using magic in the wizarding world.
It would be quite a wild concept. Naruto's energetic and determined personality would likely have a big impact on Harry. He might teach Harry some physical combat skills alongside magic.
