In such fanfiction, Natsu might be depicted as more passionate and impulsive than in the original work. His fiery nature could be emphasized in a romantic or more intense context. Laxus, on the other hand, may be shown as more brooding and powerful. His strength and dominance could be a key part of the relationship dynamic in the fanfiction.
His guildmates would surely be main characters. For example, Natsu could be there. Natsu might be really confused at first but then would be super protective of baby Laxus. Another could be Lucy. She might be the one who is more practical in taking care of the baby, like making sure he has proper clothes and a comfortable place to sleep.
You can expect a lot of character development. Laxus might show his tough yet caring side, Mirajane could display her strength and femininity, and Lemon (if it's an original character) would have their own distinct traits. There could be some epic battles where they use their magic powers in unison.
I'm not sure of a specific one titled exactly like that, but you could look for fanfics on platforms like FanFiction.net or Archive of Our Own. Search for stories that involve all three characters. You might find some where Laxus and Mirajane have to team up with Lemon for a special mission in the magical world they inhabit. It could explore their different personalities and how they work together.
Once upon a time, Laxus noticed the reader during a guild event. Their eyes met briefly, and there was an instant spark. Laxus, usually gruff, found himself drawn to the reader's kind smile. He started to find excuses to be around them, like asking for help with small tasks. The reader, in turn, was intrigued by Laxus's tough exterior but soft heart. As time passed, they began to share secrets and long conversations, and slowly but surely, love bloomed between them.
One common theme could be the challenges they face as they prepare for parenthood. It might involve things like how they adjust their lives in the Fairy Tail guild with a baby on the way.
Friendship is a very common theme. Many fanfics explore how their initial acquaintance grows into a deep and meaningful friendship. For example, they might start as just guild mates but gradually become inseparable.
Often, themes of adventure and teamwork can be intertwined. Since they are from a world where they might go on quests together, fanfic could show how they rely on each other during those adventures. And in the context of a 'lemon' fanfic, there could also be themes of romance and passion, showing the more intimate side of their relationship.
One common theme could be growth. Laxus might be training Lucy to help her grow stronger in terms of her magical abilities. Another theme could be friendship. Through the training process, they could develop a deeper bond as friends.
Since 'lemon' fanfics are not appropriate to discuss in detail, we can consider the general themes that could be adapted in a more appropriate way for Laxus and Mirajane. One could be the idea of redemption. Laxus has his own journey of redemption in the series, and Mirajane also has her past traumas to overcome. Their relationship could be explored in the context of helping each other heal and grow. Another theme could be family, as the Fairy Tail guild is like a big family, and their relationship could be seen as part of that family dynamic.
