They could also be brought together by a common cause like protecting a magical artifact that is important to both of their worlds. Working towards this goal side by side, facing difficulties and making sacrifices together would gradually strengthen their bond in a non - sexual way.
Another way is through mutual respect for each other's skills. Erza Knightwalker is a very skilled fighter, and Natsu is as well. They could train together and learn from each other, which would bring them closer. This respect for one another's abilities could then turn into a more affectionate relationship over time.
Their relationship can be developed through shared adventures. For example, they could team up to save a group of people from a powerful enemy. In the process, they would learn to trust each other more and more, and this trust could be the foundation of a deeper connection.
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.
One common theme is the exploration of their relationship in an alternate universe. Since Erza Knightwalker is from a different world in the Fairy Tail lore, fanfictions often play with how Natsu and her interact and fall in love in this new setting.
One unique way to develop their relationship could be through a shared loss. For example, if a beloved member of the guild was killed. Natsu might react impulsively with anger, Erza would be more stoic but determined for justice, and Mirajane would be the one to comfort them both while also being sad herself. This common grief could bring them closer together, with Natsu realizing he can rely on the two women in different ways. Erza could see Natsu's softer side and Mirajane could see a new depth to Erza.
In many fanfictions, Natsu and Erza often have a complex relationship. Natsu is usually depicted as a bold and passionate character, while Erza is strong - willed. Their relationship might start from comradeship within the guild. Some fanfictions may explore how they gradually develop deeper feelings for each other, like through shared adventures and facing challenges together. This can lead to a mutual understanding and respect that could potentially turn into a romantic relationship.
You can start by looking on popular fanfiction websites like FanFiction.net or Archive of Our Own (AO3). On these platforms, you can simply search for 'Natsu x Erza Knightwalker' in the search bar, and it should bring up relevant stories. Just make sure to check the ratings and summaries to find the ones that suit your taste.
Their relationship can be developed through shared battles. For example, in a tough fight against a strong guild from another town, they rely on each other. Natsu protects Erza when she's in a vulnerable state during a requip, and Erza in turn uses her strategic mind to guide Natsu's brute force attacks. This mutual dependence can strengthen their bond.
Their relationship could be developed in a unique way if they had to swap magic powers for a short period. Gray having to use Erza's requip magic and Erza using Gray's ice - magic would force them to understand each other on a deeper level. They would have to train together to master the new powers, which would lead to a lot of close - quarter interactions and shared experiences.
Their relationship can be developed through a mutual respect for their ninja skills. For example, they could train together and learn from each other's techniques. Neji could teach Hinata how to better use her Byakugan in combat, and Hinata could show Neji how to be more empathetic towards others in battle situations.
In Natsu x Erza fanfic, their relationship can be full of adventure - based camaraderie. Natsu is often depicted as the impulsive and powerful mage, while Erza is the strong - willed and disciplined one. They might team up frequently, with Natsu's spontaneity contrasting Erza's calculated moves. This can lead to interesting character dynamics, where they both learn from each other and grow together in their fictional adventures.
They could develop a mentor - mentee relationship. Carlisle, with his vast knowledge and experience, could teach Bella about the history and culture of vampires. Bella, in turn, could offer Carlisle new perspectives from her modern - day human upbringing. This kind of exchange would strengthen their relationship in a non - romantic way. For instance, they could have long discussions about how vampires have adapted over the centuries and how modern society affects their existence.
