They might face challenges from their own families. Naruto has no real family left in Konoha in the traditional sense, but the village elders and his friends might have certain expectations. Kurotsuchi's family in Iwagakure could also have their own ideas about how she should behave as a married woman. Moreover, the threat of external enemies still exists. Enemies might target their relationship as a way to create chaos between Konoha and Iwagakure, forcing them to constantly be on guard and potentially straining their marriage.
In a married fanfiction, Naruto and Kurotsuchi may face challenges in terms of their busy schedules. Naruto, as Hokage, has a lot of responsibilities in Konoha, and Kurotsuchi also has important duties in Iwagakure. They might struggle to find time for each other. Also, there could be political pressures. Their marriage is not just a personal union but also a connection between two powerful villages. Political factions in both villages might try to use their marriage for their own gains, putting stress on their relationship.
One challenge could be the difference in their villages' cultures. Konoha has a more laid - back and diverse culture compared to Iwagakure which is more traditional and strict. Naruto and Kurotsuchi would have to find a way to blend these cultures in their married life. For example, in terms of family traditions and how they raise their children.
Communication could be a big issue. Naruto has his own way of expressing himself in his world, with his ninja jargon and unique gestures. Kim, with her own lingo from her action - packed life, might find it hard to fully understand Naruto at times. Also, they both have their own sets of friends and allies. Naruto's friends like Sasuke and Sakura might not immediately get along with Kim's friends like Ron and Rufus. This could cause some tension in their married life.
One challenge could be the difference in their upbringing. Naruto grew up in Konoha with a sense of community and family, while Tayuya was part of Orochimaru's group. Their different values might clash at times. For example, Naruto might be more open and trusting, while Tayuya could be more guarded.
One challenge could be dealing with their different clan cultures. Naruto is from the Uzumaki clan and Hana from the Inuzuka clan. Their traditions regarding family, festivals, and even child - rearing might be different. Another challenge could be Naruto's dangerous missions. Hana would be constantly worried about his safety, and Naruto would have to balance his duties and his new family life.
One challenge could be acceptance from their respective villages. The Leaf village might be hesitant to fully accept Haku, given his past association with Zabuza. Similarly, the Hidden Mist might have reservations about Naruto, a Leaf ninja. Another challenge could be jealousy from other characters who might have had feelings for either Naruto or Haku. For example, some of Naruto's female friends in the Leaf village might not be happy about his marriage to Haku.
In fanfiction, cultural differences between Konoha and Suna could pose a problem. Their wedding traditions, family values, and even the way they celebrate holidays might be different. For instance, Konoha might have a more elaborate and festive wedding ceremony, while Suna's could be more austere. Also, they might have different views on raising children. Naruto, coming from a more lenient environment in Konoha, might clash with Temari's stricter Suna - influenced parenting style. And then there's the matter of their friends. Some of their friends might not get along well, which could put a strain on their marriage.
One challenge could be cultural differences. Naruto comes from a world of ninjas with its own set of traditions and values, while Soifon is from Soul Society which has a very different way of life. For example, the way they celebrate festivals or handle family matters might be completely different.
One challenge could be cultural differences. Naruto is from a ninja village where things like honor are defined differently compared to Arturia's world of chivalry. Another might be the expectations of their people. Konoha ninjas and Arturia's subjects would have different ideas about how a married couple should behave. Also, they have different power sources. Naruto's chakra and Arturia's magic could cause some misunderstandings when they try to work together in battles or other situations.
One challenge could be time management. They are both important figures in the fight against evil in the Voltron universe. So, finding time for each other between battles and diplomatic meetings would be tough. For instance, Keith might be called away on a dangerous mission right in the middle of their anniversary celebration.
One challenge could be dealing with different family expectations. Shizuru's family might have certain traditions they expect her to follow in the marriage, while Natsuki's family could have different ideas. For example, Shizuru's family might want a large, elaborate wedding ceremony, while Natsuki's family prefers a more simple and private affair.
