Sure. A lot of fanfic writers prefer to stay away from adult - themed content. They might write about how Erza Scarlet and Erza Knightwalker could team up against common enemies. Maybe they'd write about how they learn from each other's fighting styles or how they come to understand each other's pasts better. So, it's very possible to find non - 'lemon' fanfics about them.
One plot idea could be that a group of dark mages kidnap Erza to use her as a bargaining chip against her guild. They know her strength and reputation, so they think they can force Fairy Tail to give up some valuable magical artifacts. Another could be that an obsessed fan of Erza's kidnaps her, believing that she can be 'tamed' and made to love him. This could lead to a story of Erza having to outwit this deranged individual while also trying to escape from his clutches.
The story could end with Erza escaping on her own. She uses her incredible combat skills and strategic mind to break free from her captors. She then returns to Fairy Tail, where she is greeted with great relief and celebration. And she vows to find and punish those who dared to kidnap her.
There are many fanfics about Erza Scarlet. Some focus on her adventures, her relationships with other characters in a platonic way, like her strong friendship with her guild mates in Fairy Tail. You can find these on various fanfic websites.
Common themes in Erza Scarlet fanfics include her leadership skills. As a strong and respected member of Fairy Tail, she is often depicted as leading missions or guiding other characters. Her backstory is also a popular theme. Writers like to explore her past traumas and how she has overcome them, which adds depth to her character in the fanfics.
It could start with Naruto being found in the Fairy Tail world as a baby, with Erza taking him in as her own. She might notice something special about him right away, like his strong will that reminds her of herself. Then as he grows up, he starts to show signs of both ninja and magic abilities, which puzzles everyone in the guild but also makes them excited to see what he'll become.
His abilities would be a blend of the two worlds. He could have Erza's ability to sense magic and Naruto's ability to sense chakra. This would give him an edge in detecting enemies. He might be able to create clones that are part ninja clone and part magical projection, like a combination of Naruto's shadow clones and Erza's magic. His physical strength could be enhanced by both Erza's training in the Fairy Tail guild and Naruto's training as a ninja. He could also have the ability to teleport short distances, a combination of Naruto's body flicker technique and Erza's magic - based movement abilities.
One idea could be a story where they accidentally swap bodies. This would lead to a lot of comical situations as they try to adapt to each other's lives. They'd have to deal with different relationships within their respective guilds or groups while also learning more about each other's personalities.
It could be a story where Naruto grows up in the Fairy Tail world instead of the Hidden Leaf. Since Erza is known for her strict but caring nature, she would probably train Naruto really hard. Naruto might have a different set of values influenced by the Fairy Tail guild. He could also make some new friends among the Fairy Tail members and together they could face powerful enemies. His ninja way might get a new interpretation in the context of the Fairy Tail universe.
Well, one way it could work is through some sort of multiverse or time - travel concept. Maybe in a world where different anime universes collide. The Naruto male character could inherit some of Erza's traits like her determination and combat skills. He might also have a similar sense of justice. For example, if he has her magic in some form, he could use it in a way that combines with his ninja abilities, like using her requip magic to quickly change weapons during a fight, similar to how a ninja would use different tools.
