Well, of course, Eren and Mikasa are the main characters. Eren has always been a complex character with his own goals and desires. Mikasa has been by his side through thick and thin. In this fanfiction, as they are married, we get to see a different side of them. Maybe we'll see Eren being more domestic and Mikasa showing her softer, more affectionate side.
Well, in a Levi and Mikasa married fanfiction, it could be that they have a very adventurous married life. Since both are skilled fighters, they might go on missions together to protect their community. Their relationship would be based on deep respect. Levi would admire Mikasa's strength and Mikasa would look up to Levi's leadership. And when they're not out fighting, they could be teaching the younger generation their combat skills.
One possible plot could be that Eren and Mikasa have a simple and peaceful married life. They might build a small house near the ocean. Eren could be fishing to support their family while Mikasa takes care of their home, cooking delicious meals and tending to a small garden. They would have quiet evenings together, reminiscing about their adventures in the past.
Yes, there are quite a few out there. You can start by looking on fanfiction websites like Archive of Our Own. Some of these fanfics might explore their married life in different scenarios, like in a post - Titan world where they are rebuilding society together.
One possible plot could be them having to protect their new family from any remaining Titan threats. They would use their skills and knowledge to keep their loved ones safe.
Their personalities would mostly complement. Levi's no - nonsense attitude and Mikasa's focus would make them a great team. For instance, when planning for the community's defense, Levi's strategic mind and Mikasa's ability to execute plans would work together smoothly. However, there could be some clashes. Levi's harshness might sometimes bother Mikasa, but she would understand it's his way of caring. And Mikasa's occasional over - protectiveness could annoy Levi, but he'd know it comes from a good place.
Armin is often a popular character. He might be like a wise uncle figure to Eren and Mikasa's family, offering advice and support. Another could be Levi. He could be the strict but caring mentor to their children, teaching them important skills.
Since I don't know the details of the 'mikasa christmas story', I can't say for sure who the main character is. But if Mikasa is a name of a person in the story, then Mikasa would likely be the main character.
In the manga, Mikasa's story doesn't have a traditional romantic ending. Her relationship with others is complex and not centered around a romantic partner. She's primarily driven by her loyalty and duty towards Eren and her comrades.
