There are also fanfictions where their relationship is more of a mentor - mentee type. Mirajane, being more experienced in the guild, could teach Lucy a lot about the history of Fairy Tail and how to handle different magical situations. Lucy, on the other hand, could bring new ideas and a fresh perspective to Mirajane, which could help her in her own magical growth.
In fanfiction, Mirajane and Natsu could have a very interesting mentor - mentee relationship. Mirajane, being more experienced, could teach Natsu some new magic techniques or how to better control his power. This would add a new dynamic to their interactions within the Fairy Tail guild.
They could also have interactions centered around the guild's social events. Maybe they compete in a friendly cooking contest at the guild hall. Lucy might be a bit clumsy in the kitchen, and Mirajane, with her more domestic skills, could teach her some tricks. This would not only be fun but also strengthen their bond as guild mates.
The love story between Natsu and Lucy in fanfiction can be seen as an expansion of their relationship in the original Fairy Tail series. Writers often play with their personalities. Natsu's fiery and impulsive nature contrasts with Lucy's more rational and kind - hearted self, and this contrast creates a lot of interesting interactions that can lead to a budding love. There are also fanfictions where they confess their feelings in the most unexpected and heart - warming ways.
To develop their relationship, start with small interactions. Have the OC offer to help Lucy with her celestial spirit summoning, like finding a rare ingredient for a spirit - summoning spell. Then, they could have some shared experiences, such as getting trapped in a cave during a mission. This forces them to rely on each other, talk, and get to know one another better. Another way is to give them common goals. For example, they both want to defeat a certain dark mage who has been causing trouble in the area. Working towards this goal together will bring them closer.
They have a close and evolving friendship. They support each other in battles and adventures.
The relationship can be developed through shared experiences. For example, if they are both involved in rescuing a kidnapped guild member. They'll face danger together, and Freed might use his magic to protect Lucy from harm, which will make Lucy see him in a new light. This will create a sense of trust between them.
In some fanfictions, their relationship develops through shared battles. As they fight side by side against enemies, they start to trust each other more and more, which deepens their connection.
In fanfiction, Natsu and Mirajane's relationship can be really interesting. Some fanfics might start with their initial interactions in the guild. Natsu is often shown as his energetic self, and Mirajane, with her kind yet mysterious side. Their relationship could develop gradually as they go on adventures together in the fan - created stories. Maybe Natsu helps Mirajane overcome some past traumas she has, like her issues related to her demon side. And in return, Mirajane could offer Natsu more emotional support than he's used to, since he usually just focuses on fighting and protecting the guild.
Lucy could give Aquarius more freedom outside of the key. Let her experience the human world more often. They could go on adventures that are not related to Fairy Tail's main quests, just the two of them. This would allow them to get to know each other on a more personal level. Aquarius could also teach Lucy more about celestial magic and its deeper secrets, which would bring them closer as they explore this knowledge together.
In some fanfictions, their relationship could be a romantic one. Writers might explore how they meet and fall in love within the Fairy Tail universe.
