Another emotional moment could be when Naruto discovers his father's dreams and hopes for him through some form of memory or message. If he sees that his father always believed in him and had great expectations, it can be both heart - warming and overwhelming for Naruto.
When Naruto finally realizes the sacrifices his father made for the village and for him. For example, learning that his father sealed the Nine - Tails inside him to save the village at the cost of his own life. This realization can be a very emotional moment as Naruto understands the depth of his father's love and selflessness.
In many fanfictions, it could be through finding old documents or letters. Maybe he stumbles upon a hidden scroll in his home that contains some information about his father. For example, it might be a letter from his father to his mother that gives some clues about his father's personality or his role in the village before Naruto was born.
Iruka could be one. He's always been like a mentor to Naruto. He might have some knowledge about Minato that he shares with Naruto. For example, he could tell Naruto about his father's kindness towards students at the ninja academy.
Well, in some fanfics, Naruto might first discover his father's identity through a hidden scroll. This could lead to him learning about his father's special jutsu. For example, he could find out about Minato's Flying Thunder God Technique and start training to master it himself, seeing it as a connection to his father.
The Third Hokage, Hiruzen Sarutobi, would be a very important character. He was around when Naruto's parents were alive. He could have hidden records or memories that he might share with Naruto. Another possibility is Jiraiya. He was Minato's teacher and Naruto's godfather. He would have a wealth of knowledge about Minato and Kushina, and he could be a key figure in helping Naruto learn about his parents.
One challenge could be the complexity of the jutsu itself. His father's jutsu might be very advanced and require a high level of chakra control that Naruto doesn't initially have.
Well, in many such fanfictions, Naruto might start learning his father's jutsu when he discovers some hidden scrolls or when a mentor who knew his father decides to teach him. Maybe it could be someone like Jiraiya who reveals some secrets about his father's techniques.
One possible plot twist could be that his heritage is linked to an enemy he thought was unrelated. So he has to reevaluate his views on the whole conflict.
Another plot point could be Naruto meeting an old acquaintance of his parents. This person could share stories about how his parents met, their early days together, and the kind of people they were. For example, they might talk about how Kushina was a feisty and strong - willed woman, and how Minato was a prodigy with a kind heart. This would help Naruto see his parents as real people with their own personalities and not just as the heroes who sacrificed themselves for the village.
One of the most emotional moments is when Naruto promised Sakura that he would bring Sasuke back. Naruto's selfless act showed his love for Sakura. He was willing to risk his life to fulfill her wish, and Sakura was deeply touched by his determination. Another moment could be when Naruto was in danger and Sakura was really worried about him. Her concern for Naruto at that time revealed the special bond between them.
Definitely the moment when Hinata confessed her love to Naruto during the war. It was a very powerful scene as it took a lot of courage for her to do so. Also, when Naruto finally realizes his feelings for Hinata and they start to interact more romantically. And of course, the scenes where they are shown together as a family in the Boruto series are also quite memorable.
