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.
There are indeed some great ones. In some fanfictions, they might start off as friends but gradually realize their deeper feelings for each other. For example, a story could have Natsu noticing Mirajane's different sides during a difficult mission, and that newfound understanding leads to romantic feelings. Another common theme is where Mirajane has to help Natsu deal with his past traumas, and through that process, love blossoms between them.
The idea of entropy in a Natsu and Mirajane's child - related Fairy Tail fanfiction could be really cool. Entropy often represents chaos and disorder. In the context of the story, it might be that the child is born during a time of great upheaval in the Fairy Tail world. Their powers could be linked to entropy, meaning they can either create or restore order. Maybe the child has the ability to sense when things are going wrong in the magical balance of the world. For instance, if a dark magic is spreading and causing disorder, the child's entropy - related magic could be the key to countering it, by either absorbing the chaos or transforming it into something positive. This would make for a very unique and exciting fanfiction concept.
Perhaps in a fan - made apocalyptic version of the Fairy Tail world. A great evil has spread across the land, and Mirajane is at the forefront of the fight. However, the evil is too strong and manages to mortally wound her. She dies in the arms of her guildmates, and her death serves as a catalyst for the remaining members to fight even harder to defeat the evil and restore peace.
One of the main things that makes 'Fairy Tail Natsu x Mirajane fanfiction' appealing is the opportunity to create a unique love story within the magical world of Fairy Tail. Fans can imagine how their magic would interact in a romantic context. For example, Natsu's fire magic and Mirajane's take - over magic could be used in creative ways to save each other or have special moments together. Also, seeing these two characters, who are both important to the guild, develop a deep emotional connection is very satisfying for readers.
One great 'Fairy Tail Natsu x Mirajane fanfiction' is 'A New Bond'. It beautifully explores their relationship in a post - Tartaros arc setting, showing how they support each other through the rebuilding of the guild. Another interesting one is 'The Unseen Connection' which delves into their shared past traumas and how that brings them closer.
Their relationship would likely become more intimate and deeper. With a baby on the way, they'd have to rely on each other more. Natsu would probably become more gentle and caring towards Mirajane, and Mirajane would feel more protected by Natsu.
First, show their initial meeting. Maybe the OC is in awe of Mirajane's power and beauty. Mirajane could be kind and welcoming to the new face in the guild. Use dialogue to convey their personalities. For example, Mirajane might say something encouraging like 'Don't worry, we all start somewhere in this guild.'
One way is through the child's magic. If the child has a magic related to entropy, it could be shown as a force that is hard to predict. For example, the child might not be able to fully control when they use their entropy magic, and it could randomly affect things around them, like changing the temperature or the state of objects in the guild hall.
The guild would be in deep mourning. Elfman and Lisanna would be especially devastated as she is their sister. The guild's morale would take a huge hit. Mirajane was often a source of strength and stability for the younger members. Without her, there would be a sense of emptiness in the guild hall.
