Ichigo's family, especially his father, would need to adjust to the idea of Ichigo being part of the Soul Society in a more permanent way through his marriage to Kukaku. His sisters would be curious and excited to learn more about Kukaku's world. His friends in Karakura Town would initially have mixed feelings. Some might worry that Ichigo will be too involved in the Soul Society now. However, as they see how happy he is, they would come around. For Kukaku's friends and family in the Soul Society, they would have to accept Ichigo, who is not a typical Soul Society member. This could lead to some cultural exchanges between the two groups. Kukaku's family might start to incorporate some human traditions into their own, and Ichigo's family might learn more about Soul Society customs, all because of their marriage.
For Percy's family, it would be a huge shock. His mother would probably be worried at first because Athena is a goddess. But then she might see how much Percy loves Athena and come to accept it. His friends like Grover would be in awe and might also be a bit jealous. As for Athena's side, the other gods would be divided. Some might see it as a new era of cooperation between gods and demigods, while others would be against it as it goes against the norms.
For Naruto's world, his relationship with Inner Moka could cause some initial unrest. But as people see how much they love each other, it could lead to a more inclusive society. The Leaf Village could start trading knowledge with the vampire world. In Inner Moka's world, her marriage to Naruto might inspire younger vampires to be more adventurous and look beyond their own kind for relationships. It could also lead to a cultural exchange, with vampire traditions being shared in the ninja world and vice versa.
If Ichigo and Yoruichi get married, it could change the power dynamics in Soul Society in many ways. Ichigo has human and Hollow powers, and Yoruichi has her own unique abilities. Their combined strength would be a force to be reckoned with. This might make the Gotei 13 more cautious about dealing with them. They could also inspire a new generation of shinigami to be more open - minded about relationships between different races, like humans and shinigami. Which in turn could lead to new power blocs forming within Soul Society.
After getting married, their relationship would deepen on many levels. Inuyasha would become more protective in a different way. Instead of just protecting her from demons, he would be more concerned about her overall well - being, like making sure she's not too stressed with household duties in the feudal era. Kagome, on the other hand, would try to integrate more into the feudal era society as Inuyasha's wife. She would start to take on more responsibilities in their home and within the community, and they would support each other in these new roles.
For Peter Parker, being married to Catwoman would likely make him more of an outlier in the superhero community. He might be seen as someone who has strayed from the 'good guy' path a bit. His identity as Spider - Man could be more complex, as he now has a connection to a character with a more morally gray past. For Catwoman, she would probably be forced to reevaluate her identity. She might see herself as more of a hero - adjacent figure, and her relationship with Peter could inspire her to use her skills for more noble causes, rather than just for personal gain.
After getting married, they would likely have to navigate sharing living spaces more permanently. This could lead to both small and large adjustments. Small things like getting used to each other's bathroom habits, and larger things like deciding how to merge their careers and personal lives. There would also be a new level of commitment that might make them more protective of their relationship.
Their relationship would likely become more intimate and complex. Since they are married, they would have a stronger bond. They might start to understand each other on a deeper level. Maybe Jasper would be more protective of Bella, and Bella would become more involved in Jasper's past and his experiences as a vampire. They would also have to face new challenges together as a married couple within the vampire world.
Alex's career at the DEO might see some changes. Since Cat is a high - profile media figure, the DEO might be more cautious about certain operations to avoid negative press. On the other hand, Alex could use Cat's media connections to get better intelligence and resources. For Cat, her relationship with Alex could make her a target for some of the DEO's enemies. However, it could also make her more respected in the media world as someone who is married to a hero. Their marriage would mean a constant negotiation between the secrecy of the DEO and the transparency of the media.
Ichigo's family on the other hand, would also be surprised. His father might be a bit more open - minded though, given his own strange abilities and knowledge of the spirit world. His sisters would likely be excited about having Byakuya as a brother - in - law, especially if they see how much Ichigo cares about him. Overall, Ichigo's family would probably welcome Byakuya once they get to know him better.
Ichigo's family might be a bit surprised at first. His father, Isshin, would probably be happy in the end though, seeing his son find love. His sisters might be excited to have Rangiku as part of the family and look forward to all the fun they could have together. As for Rangiku's side, if she has any family in the Soul Society, they might be a bit more hesitant. They might worry about how a relationship with a human like Ichigo could work out in the long run, but eventually come around when they see how much they love each other.
