Definitely not. Fanfiction should stay within the boundaries of respect and legality. When it comes to a work like 'Miss Kobayashi's Dragon Maid', the focus should be on the positive aspects such as the unique friendship between the characters, the cultural elements, and the fun adventures. Sexualizing a character like Kanna is unacceptable behavior.
I'm not entirely sure as I haven't read this specific fanfiction. But generally, in 'Miss Kobayashi's Dragon Maid' fanfictions, they often explore different relationships between the characters in new and creative ways. It might involve the dragons and Kobayashi in some unique adventures or emotional developments that deviate from the original story. Since it has'shrink' in the title, perhaps it has something to do with the characters being shrunk and the resulting comical or interesting situations that follow.
One common theme is the exploration of cultural differences. Since the dragons come from a different world, fanfictions often play with how they interact with human culture. For example, they might be confused by human holidays or social norms.
The themes include acceptance. Kobayashi accepts Tohru into her life despite her being a dragon, and this acceptance spreads to others in their circle. And there's the theme of transformation. Tohru is constantly changing and growing as she experiences life in the human world, from her understanding of human emotions to her daily habits.
Well, the plot might focus on the cultural differences in a wedding. Since Tohru is a dragon, there could be some dragon customs that seem strange to the humans around them. For example, dragons might have a special ceremony to show their eternal bond which involves some magic or a flight display. And Kobayashi has to figure out how to incorporate these into a wedding that also makes sense in the human world.
The guests would include all of Tohru and Kobayashi's closest friends. Kanna would be an important part of the wedding as she has a special bond with both of them. Lucoa, with her flamboyant personality, would add a touch of fun to the event. Elma, being another dragon, would represent the dragon community. And Kobayashi's friends from work, like Makoto, might be there too. There could also be some new characters introduced as guests, like other dragons who are friends of Tohru from far - away places or human friends of Kobayashi that we haven't met before.
Tohru is definitely one of the most interesting. As a dragon maid, she has her own set of dragon - like behaviors and powers, yet she's trying to adapt to human ways. Her relationship with Kobayashi is full of comical and heartwarming moments. Kanna is also interesting. She's a young dragon with a cute and innocent appearance but has her own little quirks and a big appetite.
