Family is a big theme too. The maids and Kobayashi form a sort of family unit. In some fanfictions, they celebrate human holidays together like Christmas or New Year's, showing how they've become a family. Also, the theme of self - discovery is present. Dragons learn more about their own identities and powers as they interact with the human world. For instance, Kanna discovers new things about her dragon heritage while at school.
One great 'Ms Kobayashi Dragon Maid' fanfiction is 'A New Beginning'. It adds a really interesting new adventure for Tohru and Kobayashi, exploring Tohru's past in more depth.
One common theme is the exploration of different cultures. Naruto has its own ninja - based culture, and Dragon Maid has a more modern - day Japanese with a touch of magical dragon culture. Fanfictions often play with how these cultures interact. Another theme is the power differences and how characters from both worlds adapt to each other's power levels. For example, how a powerful dragon from Dragon Maid would view the ninja powers in Naruto.
A really interesting fanfic concept could be where the dragons from Dragon Maid are mistaken for powerful summons in the Naruto world. And the Naruto characters have to figure out how to deal with these strange, sentient summons. It could lead to a lot of humorous and action - packed situations as the two groups try to understand each other.
One of the main themes is the relationship between Kobayashi and Tohru. Their interactions, from Kobayashi's initial acceptance of Tohru into her home to their growing bond over time, are central. Another theme is about family and belonging. Tohru and the other dragon maids create a sort of surrogate family around Kobayashi, and they all learn to live together in the human world, adapting to human customs while still maintaining their dragon identities.
One popular idea is exploring different dragon cultures in the fanfic. Since the series has various dragons with their own unique traits, fanfics might delve deeper into how these dragon cultures function, like their social hierarchies or mating rituals. Another idea could be focusing on the daily life of Kobayashi and Tohru in more detail, such as how they handle holidays or special occasions that are important to dragons but new to Kobayashi. Also, some fanfics may create new dragon characters and explore their relationships with the existing cast.
