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.
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.
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.
