One great fanfiction is 'Natsu and Lisanna's Adventure'. It beautifully portrays their relationship development. It starts with a simple quest they embark on together, and as they face challenges, their bond deepens. The author does a wonderful job of showing Natsu's protective side towards Lisanna and Lisanna's admiration for Natsu.
In some fanfictions, Natsu might save Lisanna from a powerful dark wizard. He could use his Fire Dragon Slayer magic to overpower the enemy and rescue her.
Another aspect could be their relationship growth within the marriage. They might have deep conversations about their past traumas and how they've overcome them. It could also show how their love has changed and become even stronger over time, with little romantic moments like stargazing together on the rooftop of their home.
The chemistry between Natsu and Lisanna has to be well - written. It should feel natural, like their banter and the way they support each other. A good fanfic might also include some backstory, like their childhood memories. This gives depth to their relationship. Also, the fanfic should fit within the world of 'Fairy Tail'. So, the magic, the guild, and the other characters should be incorporated in a way that makes sense.
There are several great authors. One of them is [Author Name1]. Their stories are known for their detailed descriptions of Natsu and Lisanna's relationship. They really capture the essence of the characters. Another good author is [Author Name2]. Their fanfictions often have unique plot twists that keep readers hooked.
One popular storyline is where Natsu and Lisanna go on an adventure together to find a long - lost magical artifact. This adventure tests their relationship and their individual strengths. Another is a story where they have to team up to save the Fairy Tail guild from a powerful enemy. It often involves them using their unique magic skills in creative ways.
In many fanfictions, their relationship is often characterized by a deep loyalty. Natsu is always there to protect Lisanna, and Lisanna is a source of support for Natsu. For example, in some stories, when Natsu gets into a tough fight, Lisanna is the one who heals his wounds and gives him the motivation to keep going.
Another idea in fanfiction could be a 'what if' scenario. What if Lisanna never 'died'? In this case, their love could have blossomed earlier. They might have been a couple throughout the main series, and fanfictions could explore how that would have changed the dynamics between Natsu and the other characters like Lucy.
