Naruto might be initially confused. He's used to being the one chasing after recognition and friends, so having his sister be so obsessed with him would be a new experience. He could be a bit awkward around her at first.
He might also feel a great sense of responsibility. Since his sister is so focused on him, he would want to be a good role model. So he'd start taking his training and ninja duties even more seriously. He would try to teach her important ninja values like perseverance and loyalty. For instance, he could start including her in some of his training sessions, but also make sure she doesn't overdo it. He'd be constantly worried about her getting into trouble because of her obsession with him.
Eventually, Naruto would probably accept her obsession with love. He's a very kind - hearted person. He'd see that her obsession comes from a place of deep admiration and love for him. So he'd start involving her more in his life, sharing his dreams and fears with her. He might even start depending on her in some ways, like having her as a support system during tough times in his ninja career.
Shikamaru, being the smart and observant one, would analyze the situation thoroughly. He would probably warn Naruto about the potential political pitfalls and how to navigate them. He might also offer some strategic advice on how to handle the relationship aspect, like how to communicate effectively with his new partner in the political marriage so that Naruto doesn't get caught up in unnecessary drama or power plays.
He might be angry at first. Naruto has grown up alone and had to fight for acceptance. So when his parents say they regret abandoning him, he could lash out, saying it's too late. After all, he has already faced so much without them.
The older generation, like Kakashi, would be very cautious. He has seen a lot in his life and would be worried about the implications of Naruto having such god - like powers. He would try to guide Naruto to use these powers responsibly, fearing that Naruto's inexperience with such power could lead to chaos in the ninja world.
Naruto would be over the moon. He's always been a family - oriented person deep down. He'd probably start blabbing to all his friends about how amazing Hinata is and how excited he is to be a father.
At first, Naruto might be confused and hurt. He has always wanted to be accepted by the villagers, so being beaten by them would be a huge blow. He could become angry and vow to prove himself to them.
At first, Naruto would likely be very confused and hurt. He has always craved family love and acceptance, so this sudden turn would be a huge blow. He might try to plead with his family, asking them to believe him and give him a chance to explain.
At first, Naruto would probably be extremely confused and hurt. He loves his mother and can't understand why she would do such a thing. He might try to find her immediately to talk it out.
Naruto would use his ninja skills. He might start with a diversion, like creating some clones to distract the assassin while he gets his sister to a safer place.
Sasuke would likely be very suspicious at first. He has always been on guard around Naruto, and this new revelation would make him even more cautious. He might see Naruto as a potential threat to the village or to his own goals.
At first, Sasuke might not believe it was Naruto's own will. He would try to find out if Naruto was under some sort of external influence. But if he found out that Naruto was fully responsible, Sasuke's reaction would be one of pure hatred. He would abandon all his previous beliefs and goals and make it his sole mission to destroy Naruto. He might also cut off all ties with the village that Naruto was protecting, seeing it as an accomplice in his sister's death.
