Another possibility is that Naruto marries a completely new character. This character could be from a far - off land that Naruto visits during his departure from Konoha. She could be a powerful ninja in her own right, with unique abilities and a personality that attracts Naruto, leading to their marriage.
Maybe he marries an OC (original character). The author of the fanfic could create a whole new character with unique qualities that attract Naruto during his time away from Konoha.
One possible storyline could be that Naruto leaves Konoha to explore the world and on his journey, he meets a kind - hearted and strong - willed woman. They fall in love gradually as they face various challenges together. Eventually, they decide to get married. Maybe they have a simple ceremony with friends from his travels and old friends from Konoha coming to celebrate.
He could marry Mikasa from Attack on Titan. Just think about it. Naruto's positive and determined personality would contrast with Mikasa's more stoic and protective nature. They could meet through some sort of interdimensional accident. Naruto would be fascinated by the Titans and the world outside his own, and Mikasa might be intrigued by Naruto's ninja abilities.
He could marry Hinata. Even though he's banished, Hinata might follow him because of her deep love for him. Their relationship could develop further outside the village, and they could get married and start a family.
In this fanfic, Naruto might leave Konoha to protect his loved ones from potential threats in the village. When he gets married, it could be to a character like Hinata. They might start a new life in a peaceful place, away from the chaos of ninja battles. Maybe Naruto will teach his children the values he learned on his own journey.
He could marry Hinata. They have a pre - existing relationship in the original series. Hinata has always had feelings for Naruto, so it would be a natural choice. In the fanfiction, their relationship could progress more quickly, leading to an early marriage.
Another possibility could be a new character. For example, a foreign ninja who has different skills and a unique personality. She could meet Naruto during his travels, and they could share a deep connection based on mutual respect and admiration for each other's abilities. This could lead to them falling in love and getting married.
Naruto might encounter a group of rogue ninjas. At first, they seem like enemies, but as he gets to know them, he realizes they have their own reasons for being outcasts. They could teach Naruto some unorthodox fighting styles that are not taught in the Leaf Village. Also, there could be a mysterious traveler who has knowledge about Naruto's family that even he doesn't know. This traveler could be the key to unlocking some hidden power within Naruto.
One possible plot could be Naruto marrying Hinata. They could have a big traditional shinobi - style wedding. All of their friends from Konoha would be there, like Sasuke coming back for the occasion. Naruto would be super nervous but also extremely happy. And Hinata would look beautiful in her white kimono. The wedding could be filled with lots of emotional moments, like Naruto seeing Hinata for the first time in her wedding dress and getting all choked up.
I think Hinata would be a great choice. She has always had a deep love for Naruto. Her gentle and kind nature would complement Naruto's energetic and determined personality. They also have a lot of history together, like how Hinata was always there for Naruto in her own quiet way. And in the end, Naruto also realized his feelings for her. So a fanfic about their marriage would be really sweet and full of warm, fuzzy feelings.
