In such a fanfiction, Naruto might be overwhelmed with emotions. He could finally get to understand the sacrifices his parents made for him. His father, Minato, might share some of his jutsu secrets, and his mother, Kushina, would probably embrace him tightly, telling him how much she loves him.
Naruto may also try to find solutions. Despite the heartbreak, his optimistic nature might still shine through a bit. He could start to search for ways to mend the relationship with his parents, whether it's through magic in the Naruto world or by trying to prove his worth to them.
Sasuke would be deeply affected. He and Naruto had a complex relationship, from being rivals to friends. He would likely feel a sense of guilt, as if he should have been there to protect Naruto. Sakura would be heartbroken. She had always cared for Naruto, and seeing him die in such a tragic way in front of his parents would make her feel helpless. His parents, on the other hand, would be in utter despair. His father might feel like he failed as a father again, not being able to protect his son this time either.
At first, Naruto might be a bit hesitant. He's not used to having something so personal from his parents. But then, his curiosity would get the better of him, and he would slowly unroll the scrolls, his hands trembling slightly as he realizes that he's about to learn things he has always dreamed of knowing about his parents.
In fanfiction, Naruto as a sensei often has a very unique dynamic with his genin team. He might teach them his own unorthodox ninja techniques, like his signature Rasengan. His experiences as a former underdog also shape how he trains his students, emphasizing perseverance and the power of friendship.
Minato and Kushina would likely have a complex reaction. They would be proud of Naruto's heroic deeds in fanfiction. But if they saw him being in danger or having a hard time, they would be worried. Also, if there are parts where Naruto's values seem different from what they taught him, they might be a bit confused.
Luke might be in awe. He's always been seeking his family and a sense of belonging, so meeting his parents could make him feel complete. He'd probably listen intently to whatever they have to say.
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.
Anko's a bit of a rebel in some ways. This could encourage Naruto to think outside the box when it comes to ninja tactics. He wouldn't be so bound by the traditional ways. For example, he might come up with new ways to combine his Rasengan with other jutsu based on Anko's unorthodox thinking. Also, her somewhat edgy personality could make Naruto more street - smart and less naive in the ninja world.
He could have adventures in the Forest of Death. Anko has experience there, and she could take Naruto on more dangerous and secretive missions within that area. Naruto would learn how to better handle the perils of that forest.
