Well, perhaps in this fanfiction, Naruto and Shion are brought together by a prophecy. Shion initially is hesitant about her feelings for Naruto as she has her own duties as a priestess. However, Naruto's determination and his kind heart win her over. They go on adventures together, fighting off new threats to the ninja world. And as they grow closer, they decide to get married, much to the delight of Naruto's friends like Shikamaru and Sakura who help plan the wedding.
In a 'Naruto x Shion married' fanfiction, the story could start with their wedding ceremony. It would be a grand event with shinobi from different villages attending. After marriage, Naruto discovers new aspects of Shion's personality. She might be shy in private but strong - willed in public. They could also travel together to explore the secrets of Shion's home village, uncovering ancient shinobi techniques that could benefit the entire ninja world. And of course, there would be many cute and romantic moments between them as they build their life together.
One possible plot could be that they get married to strengthen the alliance between Konoha and Shion's village. Then they have to deal with political intrigues from other villages who don't want to see this alliance grow strong.
Maybe Shion has a premonition about Naruto being in danger again. She goes to find him to warn him. During their time together trying to prevent the danger, they grow closer. Naruto sees Shion's courage and kindness in a new light. Eventually, they fall in love and get married. Their marriage could also symbolize a new era of peace and cooperation between their respective lands.
In the fanfiction, their relationship could develop gradually. Naruto, being the friendly and outgoing person he is, would approach Shion with an open heart. Shion, initially guarded, would be intrigued by Naruto. As they spend time together, Naruto would introduce Shion to his friends in Konoha. She would be welcomed into his world. Shion would in turn show Naruto the beauty and mystery of her own world. They would support each other through difficult times, like when Naruto faces political opposition in the village for being with Shion. Their love would grow stronger through these trials, and they would ultimately get married.
The plot could involve Naruto and Sakura getting married as a way to unite two important ninja clans. Their marriage could be a political move on the surface, but as time goes by, they truly fall in love. For example, Naruto might initially be hesitant about the marriage for this reason, but Sakura's understanding and support make him see the positive side. They then go on to have a family and raise their children to be strong ninjas together.
Well, their wedding would be a blend of Naruto's simple roots and Shion's more spiritual side. Naruto would surely wear his traditional orange jumpsuit, or at least a more formal version of it. Shion, on the other hand, would be in a beautiful, flowing white dress with some spiritual symbols embroidered on it. The ceremony could take place in the Hidden Leaf Village, with the Hokage's office as a backdrop. And the reception would be filled with ninja tricks and games. For example, the guests could compete in friendly jutsu battles to win prizes. It would be a unique wedding that no one would forget.
One possible plot could be Naruto getting married to a character from another anime, like Sakura from his own world crosses over to the world of One Piece and marries Luffy. This would create a lot of chaos as Naruto tries to adapt to the new world while also dealing with his new relationship. He could use his ninja skills in the pirate world, and there would be a lot of comical and action - filled situations.
One possibility is that Shion and Yuki are from different clans in the Naruto world. Their clans have some sort of feud in the past. But when they meet, they realize that they have more in common than they thought. They then try to bridge the gap between their clans while also dealing with the overarching threats in the Naruto world, such as the Akatsuki.
The plot could start with the village elders deciding that Danzo should marry a certain female ninja to strengthen alliances. The female is hesitant at first but realizes she can influence Danzo for the better. As they live together, she discovers his secrets and tries to steer him away from his more extreme actions.
One possible plot could be about how they overcome the initial shock and opposition from their friends and the ninja world. Naruto and Sasuke would have to deal with the social implications of their relationship. As Naruto gets pregnant, they might also face concerns about the safety of the unborn child considering their status as powerful ninjas with many enemies.
