One common theme is friendship evolving into something more. Often, the two female characters start as friends or comrades in the dragon maid world and then their relationship deepens romantically.
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.
I haven't actually read this specific fanfiction, but generally, in fanfiction involving Lucoa and Shouta from 'Dragon Maid', it might explore their unique relationship. It could be about how Lucoa, with her dragon nature, interacts with Shouta in different scenarios. Maybe it shows her protecting him or them having adventures together.
One common theme is the clash of different cultures. For example, when 'Dragon Maid' characters cross over with those from other anime, they often bring their dragon - related traditions and values. This can lead to misunderstandings or new ways of thinking for the characters from the other universe.
One interesting Maid Dragon fanfiction could be about Tohru's adventures in the human world that were not shown in the original anime. For example, she might encounter a new group of humans who are initially scared of her but then come to accept her after she saves them from a small disaster. Another could focus on her relationship with Kobayashi in more depth, like how they handle a misunderstanding that threatens their living arrangement.
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 friendship. The self - inserted character often forms strong bonds with the dragon maids. Another is cultural exchange, as the human character may introduce human ways to the dragons.
An interesting 'dragon maid oc fanfiction' idea is to have an oc who is from a different dragon clan than the main characters. This oc could bring in new cultural elements and traditions of the dragon world, and there could be some tension and also cooperation as she adjusts to living with the other maids and their human master.
