Prussia in the fanfic is likely to be portrayed as proud and somewhat of a maverick. He has a long and storied history that gives him a certain swagger. Germany, in contrast, might be seen as more reserved and focused on order. Prussia could be the one to initiate grand adventures, while Germany is the one who ensures everything is in proper order during those escapades. The reader gets to experience the best of both worlds, the spontaneity of Prussia and the stability of Germany.
I'm not sure specifically as I haven't read this light novel. It could be about a character named Aoi Hikaru and their adventures on Earth. Maybe it involves some sort of fantasy or science - fiction elements set in an Earth - like environment.

I'm not sure specifically as it could be a very niche or even a made - up title for a novel. It might be a love story set in a particular school or place called 'binan koukou' and perhaps related to earth defense ('chikyuu bouei bu') in some way.
Another important aspect is setting. Prussia has a rich history, so you could set your fanfic in different time periods. You could write about him during the Napoleonic Wars, or in the post - World War II era. The key is to make the setting come alive. Describe the landscapes, the architecture, and the general atmosphere of the time. And always remember to have a clear beginning, middle, and end to your story. Start with an interesting hook, develop the plot in the middle, and conclude with a satisfying ending that ties up all the loose ends.
Prussia would probably be initially confused by the mood swings. But being a loyal and loving partner, he would try his best to adapt. He might just stay quiet and listen when the reader is in a bad mood, offering a shoulder to cry on. If the reader is suddenly happy, he would join in the joy wholeheartedly.
Since I don't have much information about this novel, I can't say for sure who the main characters are. But it's likely they are students or members of the earth defense unit from 'binan koukou' based on the title.
I'm not entirely sure as I haven't read this specific light novel. But generally, a light novel often involves unique characters, a fictional world, and a story with various themes such as adventure, friendship or self - discovery. Maybe it's about the journey of Aoi Hikaru on Earth.
