Another possible fanfiction could be about Lucoa's past. How she was in the dragon world before coming to the human world. It could explore her relationships with other dragons there, and what led her to decide to come and live among humans. This would give readers a deeper understanding of her character.
I'm not sure which are the most popular ones specifically, but some might focus on Lucoa's interactions with Kobayashi. For example, a fanfiction where Kobayashi asks Lucoa for advice on dealing with the other dragons.
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.
A fanfic of 'Miss Kobayashi's Dragon Maid' can offer unique interpretations of the original story. It might explore different relationships between the characters. For example, some fanfics could focus on the friendship between Kobayashi and Tohru in more depth, showing their daily interactions and how they support each other. Fanfics also have the potential to introduce new storylines that the original might not have covered, like adventures in the dragon world that only the fanfic author has imagined.
Kobayashi is a great character for fanfiction because she has a unique personality. She's calm, collected, and has a dry sense of humor. Writers can play with this personality in different scenarios, like putting her in unexpected or comical situations.
The setting of the 'Maid Dragon' universe also adds to the allure. It combines the magical world of dragons with the ordinary human world. Fanfics can explore different aspects of this combination, like how Lucoa adapts to human customs or how humans react to her dragon - like powers. For example, a fanfic might show Lucoa trying to cook using her dragon fire in a human kitchen, which can lead to hilarious situations.
Tohru is a very prominent character. She is strong - willed and has a deep affection for Kobayashi. Her attempts to blend into human society while still being a dragon lead to many interesting scenarios. Kobayashi is the ordinary human who gets caught up in this extraordinary situation. She is often the voice of reason. Kanna, on the other hand, is cute and innocent. She is like a child in many ways and her interactions with the other characters are really sweet.
