Power struggle is a very common theme. The heir often has to fight against other claimants or those who want to usurp the throne. Another theme is self - discovery. The heir has to figure out their own identity and capabilities as they are groomed for the throne.
In this kind of fanfiction, perhaps Naruto discovers he has some royal lineage he was unaware of. He might face new challenges as the heir, like dealing with political intrigue in the ninja world that comes with being in line for a throne. He would also have to balance his new role with his existing responsibilities and relationships.
One possible storyline could be Harry facing various political intrigues as the heir. He might have to deal with those who oppose his claim and try to undermine him. Another could be his journey of self - discovery, realizing the weight of the throne and how he wants to shape the future of the kingdom.
Well, there's a fanfic called 'The Lost Heir to the Throne'. In this story, the heir has been missing for years and suddenly reappears, causing a stir in the kingdom. And 'Heir's Legacy' is also quite good. It delves into how the heir plans to build their own legacy while upholding the traditions of the throne.
Often, there are advisers or mentors. These are characters who have a lot of knowledge about the monarchy and its workings. They might be old nobles or wise scholars who help Harry understand the ropes of being the heir. There could also be antagonists like power - hungry nobles who see Harry as a threat to their own ambitions and try to get rid of him.
His usual friends like Sasuke and Sakura could be his allies. They have been through a lot with him and would likely support him in his new role. Also, Kakashi, who has been his mentor, would probably be on his side, guiding him through the political and leadership aspects that come with being heir to the throne.
I recommend "The Almighty Farmer's Daughter Reborn". The female lead was also a concubine's daughter and had a twin brother, but the two of them were not separated. This novel was mainly about the female protagonist living in a family of six siblings, and she was the only sister in the family. Her dream had always been to live a peaceful and happy life, but her family life was not harmonious. Later, she became an international top jewelry designer and returned to her hometown with a pair of cute babies. She found out that she did not give birth to twins, but triplets. One of the children looked exactly like his younger brother. I hope you like this fairy's recommendation. Muah ~๐
I recommend the two books," Rogue Female Empress: Counterattacking the Black-bellied Prime Minister " and " Demon Concubine in Power: The Tsundere Prince Spoils His Wife ", to you. Among them, the male protagonist of " The Rogue Female Empress: Counterattacking the Black-bellied Prime Minister " often held a jade pendant, and the female protagonist was the Female Empress, which met the requirements of the title. The male protagonist of " The Demon Concubine in Power: The Tsundere Prince Spoils His Wife " also had a jade pendant. Although the female protagonist was not a prince, she was still a female character that was envied by others. I hope you like my recommendation.
๐I recommend Call Me My Lord to you. This is a fantasy novel about swords and magic. The protagonist woke up to find that he was the son of a Baron of the Empire and the heir to the territory. At the same time, he had to face the Beast Tide, the invasion of the Beastmen, the competition for mineral resources, and other problems. His brother-in-law was also the heir to the throne. Let's take a look at how the protagonist led his subjects to engage in production in the foreign world and prepare for war for the people! I hope you like this fairy's recommendation. Muah ~๐
