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.
In the manga, the art style plays a huge role in defining the mood and atmosphere. The artist can use different panel layouts and shading techniques to enhance the story. For example, when there's a tense moment between the dragons, the dark shading and close - up panels can create a sense of drama. In the light novel, it's all about the written word. The author can use different literary devices like metaphors and similes to describe the dragons' powers and personalities. For example, the author might describe Tohru's cooking as a 'fiery tempest of flavors' in the light novel, while in the manga it would be shown through pictures of the food and the reactions of the characters.
There's a fanfiction where Kanna makes new friends at school. It's quite heartwarming as it shows her trying to fit in among humans while still being a dragon at heart. She has some really cute and funny moments in this one. It also delves a bit into how the other characters react to her new friendships.
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.
If you enjoy in - depth character exploration and detailed descriptions of the story's setting and backstory, then the light novel might be a better choice for you. It can offer a more immersive experience through words. For example, you can really get into the head of Kobayashi and understand her feelings towards the dragons in a more profound way through the light novel.
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.
Another good one is 'Living with Dragons'. In this fanfiction, the focus is on how Kobayashi's daily life has been completely transformed by having the dragons around. It shows the little things like how she has to adjust her grocery shopping, her living space, and her social life. It also has some heartwarming moments where the dragons show their love and loyalty to Kobayashi in unexpected ways.
