Well, it could be a really interesting exploration of their relationship in a different context. Maybe in this fanfiction, they get married to unite their clans in a new way, bringing peace to the ninja world. Their personalities, which are so different yet complementary, would create a lot of drama and sweet moments in their married life.
One possible plot could be that Naruto and Sasuke, married, are somehow transported to the DxD world. They have to adapt to the new rules and powers there while also dealing with the reactions of the DxD characters to their relationship.
One common theme is probably the reconciliation of their past differences. Since they had a lot of conflict in the original story, in the fanfiction, their marriage would be a way to show that they've moved past all that. Another theme could be the exploration of a new kind of power couple in the ninja world. They are both extremely powerful, and together, they could be unstoppable.
One possible plot could be that after many years of Sasuke being away and Naruko constantly chasing after him in her own way, they finally realize their deep - seated feelings for each other. They get married in a small, private ceremony attended by their closest friends from the village. Their married life might involve Sasuke learning to be more open and affectionate, while Naruko helps him deal with his past traumas. Together, they face new threats to the village and their family, with their combined strength and love.
The plot could involve a post - war scenario where the village is rebuilding. Sasuke and Female Naruto's relationship blossoms during this time. Their marriage could be a symbol of hope for the village. Maybe there are some who oppose the union at first because of Sasuke's past actions. However, Naruto stands by him and they prove to everyone that their love is real and strong. They might also have to deal with political issues within the village as a married couple, but they use their influence to bring positive change.
Well, they could have a very interesting life. Since Kagome is from the Inuyasha universe and Sasuke from Naruto, their different skills and cultures would blend. Kagome could use her spiritual powers to protect their home, while Sasuke's ninja skills would keep them safe from physical threats. They might also have some unique adventures together, exploring both the feudal Japan of Inuyasha and the ninja world of Naruto.
In a Sasuke and Naruko married fanfiction, their life could be filled with adventure and growth. They might go on missions together, with Sasuke's cool-headedness and Naruko's exuberance complementing each other. Their home would be a place of warmth, despite Sasuke's initially cold exterior. Naruko would bring out the softer side of him, and they'd have a family full of love and determination, teaching their children the values of the ninja world.
Well, in a fanfiction where Naruko and Sasuke are married, their relationship could be full of interesting dynamics. Sasuke, with his brooding nature, might slowly open up more to Naruko. Naruko, on the other hand, would bring her energetic and determined self into the marriage. They could have adventures together, perhaps traveling to different hidden villages and using their combined skills to solve problems. And of course, there would be a lot of emotional moments as Sasuke learns to fully embrace his family life with Naruko.
If it's a crossover with Attack on Titan, Naruto might be married to Mikasa. Given Mikasa's strong and protective nature and Naruto's never - give - up attitude, they could be a formidable pair. They would face the Titans together, with Naruto using his ninjutsu and Mikasa her combat skills.
Their married life would be an interesting blend of two very different personalities. Sasuke is often aloof and focused on his own goals, but Sakura's determination and love could gradually draw him into a more domestic routine. Maybe they would have a child, and Sasuke would be a protective father, teaching their kid the ways of the ninja world while Sakura would instill in them the values of kindness and healing. They would support each other in their respective ninja duties, with Sakura always being there to patch up Sasuke when he comes back from a dangerous mission.
The plot could involve them starting a family. Fem Sasuke might be hesitant at first, worried about passing on her troubled family history. However, Naruto is excited and encourages her. They could have a child who has a unique combination of their powers. And then they have to protect this child from various threats, both from outside the village like rogue ninjas who might want to kidnap the child for its power, and from within the village where some might be jealous or fearful of the child's potential. This would bring them closer together as they work as a team to keep their family safe.
