In a fanfiction of Shirou and Female Hercules in FSN, it could explore their relationship in a more romantic light. Imagine Shirou being in awe of Hercules' power at first, but as they spend time together, he discovers her more feminine and vulnerable side. Hercules, on the other hand, might be drawn to Shirou's unwavering sense of justice and his kind heart.
The fsn gamer fanfic often adds a layer of gamification. In the original FSN, the story follows a more traditional fantasy narrative. But in the fanfic, elements like stats, leveling up, and in - game quests might be introduced for the characters.
A fsn crossover with the world of Attack on Titan could be really exciting. For example, the Servants could help in the fight against the Titans. Saber's combat skills would be a great asset. Or a crossover with a more modern - day superhero universe. Imagine Shirou with superpowers and how he would use them. You could also have a crossover with a post - apocalyptic game like Fallout, where the characters have to survive in a desolate world while still dealing with their own Grail War - like conflicts.
First, you need to choose the other universe you want to cross FSN with. Then, study the rules and characters of both universes. For example, if it's a crossover with a game world, know the gameplay mechanics. After that, come up with a central plot. Maybe it's a conflict that involves both universes' unique elements. Next, start introducing the characters from FSN into the new universe and see how they react. Don't be afraid to change some things to make the crossover work well.
The plot could involve Shirou and Female Hercules on a quest. They might be searching for a powerful magical artifact that has the potential to either save or destroy their world. Along the way, they face various challenges that test both their physical and mental strength. Their relationship evolves as they rely on each other to overcome these obstacles.
In many of these fanfictions, the theme of growth is prominent. Both characters grow as individuals through their interactions with each other. Shirou might learn to be more assertive, and Female Gilgamesh could learn about humility or the value of others. There's also the theme of destiny. In the Fate universe, destiny plays a big role, and these fanfictions often play with the idea of whether their relationship is fated or if they are defying destiny by being together.
The FSN visual novel is quite lengthy. It has multiple routes and a rich story, which can take anywhere from 50 to 100 hours or more to fully experience, depending on your reading speed and how much time you dedicate to it.
You can try looking on fanfiction websites such as Archive of Our Own (AO3). It has a large collection of Fate/stay night fanfictions, and you might be able to find some featuring Female Gilgamesh and Shirou there. Another option could be FanFiction.net, though the content there may vary in quality and quantity compared to AO3.
The main characters include Shirou Emiya, a key protagonist. And Saber, his Servant. There's also Rin Tohsaka, another important Master in the Holy Grail War.
Saber is a very iconic character. Her noble and serious demeanor is one of the main features. She has a strong sense of justice and loyalty, which is clearly shown throughout the story of the visual novel. Her design is also quite striking, with her elegant armor and the Excalibur sword that represents her power.
