Who could be a good love interest for the Human Princess in Attack on Titan in fanfiction?

In the 'Attack on Titan' series, there is no clearly defined canon romantic interest for Levi. His character is mainly focused on his role as a soldier and his fight against the Titans. However, many fans like to ship him with various characters in fan - made love stories.

Eren could be an interesting main character in a friendly - titan fanfiction. He has a complex relationship with the titans already. Imagine if he discovers a friendly titan that changes his view of all titans. He could try to understand it better and maybe even learn to control other titans through the knowledge he gains from this friendly one.

Another plot idea could be that the human princess embarks on a journey outside the walls not just to fight titans but also to find the origin of the titans. Along the way, she meets different groups of people who have their own theories and knowledge about the titans. This journey could be filled with self - discovery as she realizes that the world outside the walls is much more complex than she thought, and she has to use her wits and leadership skills to survive and bring back important information to her people.

A powerful cult leader among the humans could be a great antagonist. They might see the godlike OC as a threat to their power and influence. They could spread lies about the OC, turning the people against them, and even try to assassinate the OC to maintain their control over the walled cities.

Eren could be an interesting choice. Since he has such a complex character arc already, making him the tenth titan could add another layer to his story. He could struggle with the new power and how it changes his view of the world and his mission.

Irene Adler could be a great love interest. She's smart, cunning, and was able to outwit Sherlock once. Their relationship in the original stories had a certain tension that could be developed into a full - blown love story in a fanfiction. She challenges him and has her own secrets, which could make for an exciting dynamic.

Sasori could be an interesting love interest. They are both from Akatsuki and have a certain connection through their art, though Sasori's is more in the form of puppets and Deidara's is explosive art. Their different personalities could create a lot of tension and a unique love story.

A foreign ninja from another village might also work well. This ninja could bring a different perspective to Kabuto's world. They could meet during a diplomatic mission or a joint training exercise between villages. Their love would be a bit more challenging as they have to deal with the politics between their respective villages, but it would add an interesting layer to the fanfiction.

A strong - willed priestess could be a great love interest. She could be the one who interprets the gods' will and at first is hesitant about Hercules due to his half - god status, but then falls for his heroism.

It might also be a character who has a more complex or unexpected connection to Historia. For instance, there could be a plot twist where a character who was thought to be an enemy turns out to be the father, adding a whole new layer of drama to the story.
