Sakura would be overjoyed. She's been Naruto's friend for a long time, and she would be excited to see him start a family. She might offer to be the baby's doctor and make sure the baby is healthy. Shikamaru would probably be a bit lazy about it at first but would come around and offer his strategic mind to help protect the baby if needed.
Naruto's reaction could be complex. On one hand, he would be happy to find someone else from his clan. He has always been proud of his Uzumaki heritage despite not knowing much about it at first. But on the other hand, he might be a bit cautious. Karin has been associated with some not - so - good groups in the past. However, overall, his positive nature would probably lead him to approach Karin with an open mind and try to build a connection with her based on their shared Uzumaki roots.
Obviously, Naruto Uzumaki himself is the central character. His wife, Hinata, is also very important as she is part of his family and would play a major role in family - related storylines, like raising their children.
At first, Naruto might be shocked and confused. He would probably wonder why his own clan would do such a thing to him. He might feel a deep sense of betrayal, especially since he has always longed for a family and a sense of belonging within the Uzumaki clan. But being Naruto, he would soon turn his confusion and pain into determination. He would vow to prove himself and show the clan that they were wrong to exile him.
Naruto would probably first try to find a peaceful solution. He has always been one to believe in the power of friendship and understanding. He might try to talk to the leaders of both villages, like Gaara in the Sand, to find out what's really going on and resolve the misunderstandings.
He is probably very excited. Naruto has always been eager to learn new things and become stronger. Finding an Uzumaki scroll means he has the chance to discover something unique about his own clan, so he would be filled with anticipation.
Shikamaru, being the laid - back yet perceptive friend, would probably think that Naruto has a plan. He would be concerned but also understand that Naruto is not one to make hasty decisions without a good reason. He might keep an eye on Naruto's family in his absence and hope that Naruto will return safely one day.
Choji would be concerned for Naruto's well - being. He'd bring lots of snacks with him while looking for Naruto, thinking that Naruto might be hungry. He'd be the emotional support in the group, constantly saying that they need to find Naruto soon because he's their friend and they should be there for him no matter what.
Their family life would be full of adventure. Naruto, with his never - give - up attitude, would teach their kids important values. Sakura, being a strong - willed woman, would ensure the family stays healthy. They might often have family dinners with all their friends from the village dropping by.
There could also be friends who are so loyal to Naruto that they would consider following his request if they truly believe it's for the greater good. However, they would be deeply pained by it. Kakashi, for instance, might understand Naruto's selfless nature but would also struggle with the moral and emotional implications of taking his life.
