For the Uzumaki side, there isn't much family left, but the village elders who have come to respect Naruto would see this as a positive step. They would hope that this marriage would bring stability to Naruto's life. The Yamanaka family, on the other hand, would be a bit more complex. Ino's father would be protective at first. He would worry about Naruto's dangerous life as a ninja. However, once he sees how Naruto treats Ino with love and respect, and how Ino is happy with him, he would give his blessing. Ino's mother would probably be more easily swayed and start planning the wedding right away.
The Uzumaki family might be a bit shocked at first. But Naruto's kind - hearted nature could make them eventually come around. His mother Kushina might be more accepting as she always wanted Naruto to be happy. As for Sasuke's family, well, it's a bit more complicated.

As for Mei's side in Kirigakure, her comrades might be a bit more cautious. But once they see how Naruto can contribute to their village as well, they would accept the relationship.
Ino would likely be very concerned. She might immediately try to use her mind - reading skills to figure out what has happened to Naruto. If she can't break the hypnosis right away, she'd probably seek help from her teammates or sensei. Ino is a determined character, so she won't give up easily on saving Naruto.
Sakura might be a bit surprised at first, but she would probably come around and be happy for Naruto. Sasuke would likely be indifferent on the surface but secretly hope that Naruto is making the right choice. Hinata might be a bit sad that Naruto didn't choose her, but she would be polite and congratulate them.

One possible fanfiction could involve Naruto and Ino realizing their feelings for each other after years of being friends. They might start with a simple friendship that gradually turns into love. For example, Naruto could see Ino in a new light after she helps him through a difficult mission. They could then start dating secretly, not wanting to cause a stir in the village. Eventually, they decide to get married, and their wedding would be a grand affair with all their friends and comrades in attendance.
Tsukune's human family might be initially shocked. But if they see how much he loves Mizore, they could gradually come to accept her.

However, they could also be protective of Mizore and want to make sure Tsukune is worthy of her.

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.
The reaction of their families could be quite diverse. Natsu doesn't really have a traditional family, but his friends in Fairy Tail are like family. They would be excited and probably throw a huge party. Cana's father, Gildarts, has been absent for a while. But when he hears the news, he might feel a mix of emotions. He could be happy that Cana has found love, but also a bit sad that he hasn't been around more. However, overall, the Fairy Tail guild would embrace their union and make them feel special and loved.
