One common theme is love. Since it's a fanfiction about two characters, often the relationship between Saito Hajime and the OC is centered around falling in love, whether it's a slow - burn love or love at first sight. Another theme can be adventure. For example, they might go on a journey together to fight against some villains or to find a lost treasure.
There's also 'Saito Hajime and the Newcomer'. In this fanfiction, the OC is a new arrival in the world where Saito Hajime exists. The OC has unique abilities and through a series of events, they become close. It's a great read for those who like stories with a bit of mystery and adventure.
FGO isn't a typical visual novel. It has more gameplay mechanics and character-building features. The story is presented along with battles and strategic decisions.
There were the following FGO-related novels:
"FGO's Journey to the Other World,""Lu Mingfei Challenging FGO,""Starting from the Collapse of the World with the Card Drawing System,""Running FGO in the Ninja World,""King Arthur's Comic Journey,""Yuki's Holy Grail Journey,""The Story of Chaldeans Landing and Becoming the Director,""Saving the World from the Collapse," and "Chaldeans in Marvel." These are the different types of novels about FGO. There might be games-game systems, light novels-derivative doujinshi, funny jokes, infinite universe-infinite, and so on.

I'm not sure what 'First Lady' refers to because the name could refer to different people or characters. Can you provide more context? This way, I can better answer your questions.
There are various types of Saito and Louise married fanfiction. Some are light - hearted and focus on the comical situations that might arise from their different cultural backgrounds (since Saito is from a different world). Others can be more serious and delve into the deeper emotional bonds between them. The fanfiction can also explore how their marriage affects the political and social aspects of the world they live in, as Louise is a noble and Saito has his own unique position in that world.
In fanfics, Louise is often depicted as a strong - willed and sometimes temperamental character. She has her own insecurities, especially when it comes to her magical abilities. Saito, on the other hand, is usually portrayed as brave and loyal. He comes from a different world, which adds an interesting dynamic to their relationship as he has to adapt to Louise's world of magic.
In fanfiction, the idea of Saito and Louise being pregnant often adds a new dimension to their relationship. It could be a way to explore their growth as characters. Maybe it shows their transition into a more mature phase of their relationship, with the responsibilities of impending parenthood.
