There might be a fanfiction where they participate in a guild - wide competition. Natsu would be all about winning, Erza would be determined to show her strength and uphold her honor, and Mirajane would be there with her own set of skills. In the story, they could form an unexpected alliance with other guild members and through teamwork, overcome challenges and rivals.
In some fanfictions, they could be involved in a time - travel plot. For example, they are sent back in time to an era when Fairy Tail was first founded. There, they learn about the origins of the guild, meet the founders, and have to make sure they don't change history too much while also using their modern - day knowledge and powers to solve problems that the founders faced back then.
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.
Their personalities. Natsu is the hot - headed and impulsive one, always ready to jump into action. Erza is the strict and disciplined warrior, bringing order and strategy. Mirajane is the more laid - back but still very powerful one. Together, they create a great balance.
One great Erza and Natsu fanfiction could be about them going on a special mission together that wasn't in the original series. Maybe they have to travel to a far - off land to retrieve a powerful magical item. Another could be a story where Natsu gets hurt and Erza has to take care of him, showing a different side of their relationship. There are also fanfictions that explore what would happen if they were paired up in a magical tournament against other strong teams from the Fairy Tail guild.
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.
In some fanfictions, Natsu and Erza might have a moment where they confide in each other about their pasts. Erza could open up about her time in the Tower of Heaven and Natsu about his search for Igneel. This sharing of deep secrets would bring them closer and change the dynamic of their relationship from just being guild mates to something more like true friends who support each other unconditionally.
The way it fits into the 'Fairy Tail' universe. If the fanfiction can incorporate the magic, the guild's dynamics, and the overall world - building of 'Fairy Tail' while still focusing on Natsu and Erza's relationship, it becomes really interesting. For example, a fanfiction where the kiss is a result of a magical bond or a quest that they undertake together within the Fairy Tail world.
One great story could be 'Natsu and Mirajane's Adventure'. In this fic, they might go on a quest together, facing various challenges that test their relationship and individual strengths. It could involve them using their magic in creative ways to overcome obstacles.
A common type of fanfiction might be a love story between them. Despite their different personalities, they could gradually fall in love. For example, during a long and dangerous quest, they start to see each other in a new light. Or perhaps a story where Mirajane's past traumas are revealed to Natsu, and he helps her overcome them, strengthening their bond in the process.
One characteristic is the exploration of their personalities. Natsu's brash and hot - headed nature contrasts with Mirajane's more composed and sometimes mysterious side. In fanfiction, this contrast often leads to interesting interactions. For example, Natsu might be the one to break through Mirajane's reserved exterior with his straightforwardness.
