No. Naruto is a popular anime and manga aimed at a wide range of audiences, including children and teenagers. Fanfic that involves sexual content is inappropriate and goes against the spirit of the original work. It also violates the ethical and moral standards of the fandom.
One idea could be to create a story where the ninjas from Naruto are inserted into the political intrigue of Westeros. For example, Naruto, with his strong sense of justice, could find himself in the middle of the power struggle for the Iron Throne. He might try to use his ninja skills to bring peace to the war - torn land, much like he did in the Hidden Leaf Village.
A great 'naruto game fanfic' often has a unique take on the existing Naruto game world. If it has interesting new characters or powers that fit well within the Naruto universe, it can attract a lot of readers. For example, fanfics that introduce new types of jutsu or ninja tools can be really appealing.
First, understand the core elements of both. For Naruto, it's the ninja world, chakra, and the various clans. For Game of Thrones, it's the political drama, the houses, and the fight for the Iron Throne. Then, find a unique way to blend them. Maybe a character from Naruto gets transported to Westeros and has to navigate the complex politics using their ninja skills.
Well, it might be a fanfic that takes the concept of life being a game and applies it to the Naruto world. So, the ninja characters could be leveling up, gaining new skills in a game - like system. For example, Naruto could be on a journey to reach the 'highest level' of ninja, with each mission or fight being a step in that game - like progression.
In such a fanfic, the story could follow Naruto's journey to become the Hokage but in the context of the Iron Throne. He would have to deal with the backstabbing politics of Westeros. His friends would be his allies, like Sakura as a healer like in Naruto, but also having to navigate the dangerous court politics. And the Akatsuki could be a group similar to the Night's Watch, but with their own evil motives.
Most likely Naruto himself would be one of the main characters. He is the central figure in the Naruto universe, so it's natural for him to play a big role in the fanfic. Sasuke is also probably a main character as he is Naruto's rival and an important part of the story. Sakura could also be there, as she is often part of Naruto and Sasuke's storylines.
A possible scenario in this fanfic could be that Rias initially underestimates Naruto. But as the fight progresses, she realizes his true power. Naruto, on the other hand, has to adapt to the rules of the Rating Game which are different from his usual battles in the Naruto universe. He might have to learn on the fly how to deal with things like the game's battlefield, which could be magically created and have its own set of rules and obstacles.
Naruto could be a peacemaker. His optimistic and friendly nature might lead him to try and end the wars in Westeros. He could use his godlike powers to force the warring parties to sit down and negotiate.
Well, Naruto's ninja skills would be a game - changer in Westeros. He could use his Shadow Clone Jutsu to gather information in different places at once. For example, he could send clones to King's Landing, Winterfell, and other key locations. His Rasengan could be a powerful weapon against the White Walkers. And his strong sense of justice would likely lead him to side with the Starks, who also value honor and loyalty.
