The theme of unity is also prevalent. Naruto brings together different groups that were once at odds. He might unite different ninja villages or even different species in the fanfictions. This is in line with Naruto's character as he has always been one to strive for peace and harmony among all.
One common theme is redemption. Naruto often tries to redeem the world from its past mistakes or dark elements. For example, in many fanfictions, he aims to end the cycle of hatred that has plagued the ninja world for so long.
Another great one is 'Naruto's Utopian World'. This fanfiction delves into Naruto's vision of a perfect world. He abolishes old ninja traditions that cause harm and replaces them with more positive and harmonious ones. The author does a great job of portraying Naruto's determination and the reactions of other characters to this new world he is creating.
A common theme is the exploration of their father - son relationship. Since Minato died when Naruto was born, fanfictions often delve into what could have been if they had more time together. For example, how Minato would have been as a father figure, guiding Naruto in his ninja training and in life in general.
Friendship also remains a key theme. Even as a chunin, Naruto's relationships with his friends like Sasuke and Sakura are important. Some fanfictions might focus on how their friendships evolve in this new phase of Naruto's life. For example, they may face new challenges together and their bonds are either strengthened or tested.
The themes usually revolve around the librarian's role in the Naruto world. This includes their contribution to the growth of the characters, especially the young ninja. They can act as mentors through the knowledge they possess. Also, there is the theme of discovery. The librarian may lead the characters to discover new places, jutsu, or even forgotten aspects of the ninja history. Additionally, the idea of protecting knowledge from falling into the wrong hands is also a common theme, as the librarian has to safeguard the precious information in the library.
One common theme is the struggle with identity. Naruto, who is known for his bright and positive nature in the original series, has to come to terms with being an assassin, which is a much darker role. Another theme is secrecy. He has to keep his new identity hidden from his friends and loved ones.
One common theme is role - reversal. Since Naruto is usually a ninja, seeing him as a maid is a big change. Another theme could be the exploration of Naruto's adaptability. He has to adapt to the new role of a maid, which often includes tasks like cleaning, cooking, and serving. It also might involve themes of acceptance, as the other characters have to accept Naruto in this new and unexpected role.
Love and relationship are very common themes. Since Naruto and Hinata have a complex relationship in the original series, fanfictions often explore how their relationship develops further, whether it's them getting to know each other better, or facing challenges together as a couple.
One common theme is the growth of their relationship. Given Hinata's initial shyness and Naruto's obliviousness in the original story, fanfictions often explore how they overcome these barriers to be together.
One common theme is friendship. Given that Naruto values friendship highly in his own series and Mirajane is also part of a guild where comradeship is important in Fairy Tail. Another theme could be power - how their different powers interact or complement each other. Maybe Naruto's chakra-based powers and Mirajane's take - over magic could be combined in some creative ways in the fanfictions.
Often, there's a theme of economic development in the Naruto world. Naruto as a merchant might introduce new trading routes or products that change the economic landscape of the villages. Also, there can be a theme of overcoming prejudice. Since Naruto is a ninja first, some in the story might not trust him as a merchant at first, but he has to prove himself.
