Another theme is friendship and loyalty. Just like in the original Naruto series, the relationships between members of the peerage are important. They have to trust and support each other through various challenges. It shows how different characters from Naruto and Moka's worlds come together and form strong bonds.
One popular 'naruto moka peerage fanfiction' is 'Naruto: Peerage of the Kitsune'. It has an interesting plot that combines the Naruto universe with unique elements from the idea of a peerage. The characters are well - developed and the story has some great action scenes.
One interesting crossover could be the combination of Naruto's ninja skills with the supernatural elements of Highschool DxD. For example, Naruto's shadow clone jutsu could be used in the battles against the devils and fallen angels in the Highschool DxD world. And Moka from Rosario + Vampire (I assume that's what you mean by Moka) could use her vampire powers in new and creative ways when interacting with Naruto's characters. Maybe she could use her strength to compete with Naruto's taijutsu experts.
Well, 'evil naruto peerage fanfiction' might explore a darker side of Naruto. It could involve Naruto having an evil alignment and his relationships within a peerage system. Maybe it shows how his actions and motives are different from the original Naruto, perhaps being more self - centered or power - hungry in this fictional scenario.
In a Naruto - Rias' peerage fanfiction, the story might focus on how Naruto's chakra system interacts with the devil's power. For example, his ability to sense chakra could be enhanced or changed when combined with devilish senses. Also, his relationship with the members of the peerage would be interesting. He could form strong bonds with some, like Kiba in Naruto's world, he might get along well with the werewolf in Rias' peerage.
One idea could be a crossover adventure where Naruto and Moka find themselves in a strange new world together. They have to combine their unique abilities, Naruto's ninja skills and Moka's vampire powers, to survive and find a way back home.
Rock Lee with his incredible taijutsu skills could be a part of the peerage. His determination and physical strength would be assets. Neji, before his death, with his Byakugan and combat abilities might have been a suitable addition as well. And Hinata, with her gentle nature yet strong Byakugan - based skills, could also be considered for the peerage.
Inner Moka is also likely to be in these fanfictions. Her more aggressive and powerful side compared to outer Moka can create different scenarios. For example, she might be initially hostile to Naruto but then gradually warm up to him as she sees his good qualities.
Communication might be a big issue. Naruto comes from a world where people communicate in a certain way, and Moka is from a different, more supernatural - oriented culture. They may misunderstand each other's intentions or not be able to fully convey their thoughts. Also, if they are in a world that is not familiar to both of them, they would have to adapt quickly to the new environment while also dealing with their own personal differences.
Naruto in Rias' peerage would be quite a sight. His orange jumpsuit would stand out among the devils. He might use his shadow clones to do multiple tasks within the peerage, like scouting or helping with household chores. His positive attitude would also have an impact on the often - serious devils in the peerage.
