One common theme could be adventure. Since Inosuke is a rather wild and adventurous character, fanfics might involve him and AOI going on some sort of exciting journey together, perhaps exploring a new and dangerous area.
Some other platforms like Wattpad might also have such fanfics. However, the quality can vary. You could also check out some anime - related forums. Sometimes fans share their own written fanfics or recommend ones they've read. Keep in mind to respect the rules of each platform when looking for these fanfics.
Overcoming obstacles is a big one. There could be external factors like disapproving friends or family, or internal issues like insecurities that they have to face and overcome in order to be together in the fanfiction. This makes the story more engaging and relatable as it shows the challenges of a relationship.
I'm not entirely sure specifically what 'aoi x ginji light novel' is about without more context. It could potentially be a story about the relationship between two characters named Aoi and Ginji. It might involve elements of adventure, friendship, or a unique fictional world setting.
One common theme is the development of their relationship. It could start from friendship and gradually turn into something more romantic. Another theme is the support they give each other in achieving their goals. For example, if they are in an anime where they have some kind of mission or dream, they might encourage each other in fanfiction.
Inosuke survives throughout the manga. The story doesn't have his death as part of the plot. His character remains active and plays a significant role until the end.
