Yes, there might be some. Some fanfiction writers focus on creating family - friendly stories even with such a concept. They could explore the idea of Levi and Mikasa in a more platonic or non - adult way, like how they might support each other during an unexpected situation like a false pregnancy scare or something similar in a very innocent and friendly context.
The theme of family and legacy might also be prominent. Eren and Mikasa's relationship has always been complex, and with a pregnancy, it adds a new dimension to their family dynamic. Fanfics might explore how they plan to raise their child, what values they want to pass on, and how their family will contribute to the future of the world they live in. This can be especially interesting considering the post - apocalyptic setting of 'Attack on Titan'.
I'm sorry, I can't directly recommend specific 'Mikasa Eren' fanfics where Mikasa is pregnant. However, you can try searching on some well - known fanfic platforms like Archive of Our Own (AO3). They have a vast collection of fanfics, and you can use the search filters to look for ones related to this specific scenario.
Annie is often depicted as a more reserved and calculating character. She keeps her emotions in check and is very strategic in her actions. Mikasa, on the contrary, is more passionate and driven by her love and loyalty. She is protective and doesn't hesitate to jump into action when needed.
In fanfiction, Mikasa and Jean often have their characters explored in different ways. Sometimes, their relationship can be developed into a deep friendship. Jean might be shown as having a newfound respect for Mikasa's strength and determination. This can add new layers to their interactions within the fan - created storylines.
One possible storyline could be that Naruto, with his ability to teleport and his powerful ninjutsu, senses Mikasa in danger in the Attack on Titan world. He quickly arrives, uses his Rasengan to defeat the Titans surrounding her. Then he takes her to safety and they form an unlikely friendship, with Naruto sharing his experiences of fighting for his village and Mikasa being amazed at his powers.
In a Mikasa love story, perhaps it started from their childhood days. Mikasa was drawn to Eren when he saved her. As they grew up, her love grew stronger. She showed her love not just through words but through her every action, like always being by his side in dangerous situations. Her love was a quiet but powerful force that held their relationship together in the face of numerous challenges.
