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.
A plot could revolve around them finding a powerful and dangerous magical artifact. They initially compete to get it for their own reasons, but then realize that they need to work together to control it or keep it out of the wrong hands. Along the way, they start to respect and understand each other more.
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 idea could be an Erza Scarlet crossover with the world of Harry Potter. Erza could be a visiting wizard from another magical realm. She might attend Hogwarts for a while, and her combat skills could be put to use in the Triwizard Tournament, adding a new and exciting dynamic to the traditional challenges.
One idea could be a story where Natsu and Erza Knightwalker are on a mission together in a strange land. They face numerous challenges that force them to rely on each other more and more, leading to a deepening of their relationship. Their different personalities, Natsu's impulsiveness and Erza Knightwalker's more stoic nature, could create some really engaging character dynamics.
Another plot could involve a crossover with the Harry Potter world. Erza could be a transfer student to Hogwarts. Her magic, which is different from the wizarding magic, would create a stir. She might have to face off against Voldemort's forces while also learning about the magical world of wands and spells.
One idea could be exploring how Erza balances her pregnancy with her duties as a strong mage. Maybe she has to take a break from dangerous missions and feels a bit restless. Another could be the reactions of her friends in Fairy Tail. They might be overly protective or excited for her.
Maybe a fanfiction where Naruto and Erza Knightwalker meet during a tournament. In this tournament, different fighters from various universes are gathered. Naruto uses his Rasengan and shadow clone jutsu, while Erza Knightwalker showcases her different armors and sword skills. They start off as rivals but gradually come to respect each other as they see the similarities in their determination to protect what they love. And in the end, they might even combine their powers to defeat a cheater in the tournament who was using unfair means to win.
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.
In this fanfic, Erza might also help Naruto in terms of his emotional growth. Naruto has always carried the burden of being an outcast in the village initially. Erza, having faced her own challenges in Fairy Tail, could offer him advice and support. She could teach him the importance of loyalty to friends and comrades, just as she values her guildmates. This could lead to Naruto becoming an even more well - rounded character.
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.
One idea could be that Naruto and Erza are brought together by a powerful magic spell that transports Naruto to the Fairy Tail world. They initially misunderstand each other due to their different backgrounds and abilities. But as they face common enemies, they start to learn from one another. Naruto could teach Erza about his ninja way of never giving up, and Erza could show Naruto the power of magic and the importance of friendship within the guild.
