Their family dynamic would likely be full of energy. Natsu's exuberance and Erza's strong - willed nature would create a lively household. Natsu would bring a sense of fun and adventure, while Erza would enforce discipline and order when needed.
One great storyline could be Natsu and Erza having to protect their family from a powerful dark guild. They'd use their combined magic and teamwork to fend off the threats. Another could be them raising a young child with special powers within their family, teaching the child about love and friendship just like they've learned in Fairy Tail.
One great fanfic could be 'The Adventure of Natsu and Erza'. It focuses on their unique bond during a dangerous mission. They rely on each other's strengths and in the process, their relationship deepens in a very platonic yet heartwarming way.
One great aspect of Natsu and Erza fanfiction is the exploration of their unique friendship. In many stories, their different personalities - Natsu's brashness and Erza's strictness - create interesting dynamics. For example, there are fictions where they team up for a mission and Natsu's unorthodox methods initially clash with Erza's by - the - book approach, but eventually they learn to work together better, leading to a stronger bond between them.
One possible storyline could be a quest where the three of them have to work together to defeat a powerful dark wizard. Natsu's brute strength, Erza's strategic combat skills, and Mirajane's shape - shifting abilities would make for an amazing team. They could start off with some initial bickering due to their different personalities but gradually grow to respect and rely on each other more as the adventure progresses.
One idea could be a story where they go on a quest together. Maybe they have to find a rare magical item. Natsu's impulsiveness, Mirajane's charm, and Erza's strict leadership combine in interesting ways during the adventure.
One great fanfiction could be 'A New Adventure'. It focuses on Natsu and Erza going on a quest together that was not part of the original storyline. They face new challenges and in the process, their relationship deepens in a very platonic yet heartwarming way.
There's a fanfiction titled 'Unexpected Affection'. In this one, the kiss between Natsu and Erza occurs during a moment of high drama. It's set during a dangerous battle where they both think they might not survive. This situation leads to a very passionate and unexpected kiss that changes their relationship dynamics in the story.
Yes, there are quite a few. You can find some on popular fanfiction websites like FanFiction.net or Archive of Our Own. Just search for 'Fairy Tail Natsu and Erza romance' and you'll get a bunch of results. Some might focus on how their relationship could develop in different scenarios, like during a particularly tough battle where they realize their feelings for each other.
I really like 'The Unlikely Alliance' which is a great Natsu Erza Mira fanfiction. It shows how they can put aside their differences and work together against a common threat. The author does a wonderful job of writing their interactions, especially the banter between Natsu and Erza.
