Their relationship can become more nurturing. Natsu, who is usually brash and impulsive, might become more gentle and protective around the baby. Lucy, on the other hand, would be the more practical one, making sure the baby has everything it needs. This would make Natsu see Lucy in a new light, as a motherly figure, and he would respect her even more. Their love for each other could also deepen as they share the joys and challenges of raising a baby.
Well, with a baby in the story, Natsu and Lucy's relationship would likely develop in many ways. Natsu would start to show a more tender side, like when he holds the baby and tries to soothe it if it cries. Lucy would be the one to keep things organized, like getting diapers and food. This would make Natsu rely on her more, and he'd realize how important she is not just as a friend or teammate, but as someone he could build a family with. They'd also have to communicate better, discussing things like the baby's future, which would strengthen their bond further. And when they face difficulties in taking care of the baby, like when it gets sick, they'd support each other, and that would bring them closer together emotionally.
In a fanfiction, their relationship might develop if they start to open up more about their pasts. Lucy could share more about her family and how she came to be a celestial wizard. Natsu could talk about his search for Igneel. By sharing these deep parts of themselves, they would build a stronger emotional connection. Also, small moments like Natsu saving Lucy from a small danger, like a falling object in the guild hall, can add up and gradually develop their relationship.
In fanfiction, if Natsu and Lucy had a baby, it would be a huge shift for their relationship. Natsu would no longer be just the impulsive dragon slayer. He'd have to be a father figure. Lucy, with her kind heart, would pour all her love into the baby. They'd have to work together to balance their guild duties and family life. Natsu might bring the baby on small, safe adventures, teaching the child about the world of magic, while Lucy would make sure the baby has a stable home environment. Their relationship would be centered around this new life they've created.
In this maid scenario, their relationship could develop as Natsu starts to see Lucy in a new light. He might notice her hard - working side more and become more protective of her. For example, if other guild members tease her about her maid outfit, Natsu could get angry and tell them off.
In the shower scenario, their relationship could develop through shared vulnerability. For example, if there's a problem like the water suddenly turning cold, they might huddle together for warmth. This physical closeness could make them more aware of their feelings for each other.
Natsu would likely become more responsible. Taking care of a baby is no easy feat, and he'd have to learn things like being gentle and patient, which are not his usual strong suits. This would be a big step in his character growth.
One interesting scenario could be when the baby's first magic manifestation occurs. It might happen during a guild party and startle everyone. Another scenario is that the baby gets lost in the guild's large building, and all the members, including Natsu and Lucy, go on a frantic search. A third scenario could be the baby developing a strange bond with an unexpected celestial spirit.
Their relationship could develop through shared danger. For example, if they are trapped in a magical maze as a result of the Dragon Cry's after - effects. Natsu's impulsive nature might get them into trouble, but Lucy's strategic thinking gets them out. This mutual reliance can deepen their bond. Also, if Natsu discovers a new side of Lucy, like her hidden strength or a special magical ability she has been suppressing, he may start to see her in a new light, which could lead to a more romantic development.
The story could focus on their journey to find a new place to belong. They might meet new allies along the way who have different values and magic abilities, which would add new elements to the story. For instance, they could encounter a group of mages who use music as their form of magic.
One possibility could be that they discover they're having a baby unexpectedly. Natsu might be initially confused but then super excited. Lucy would probably be a bit more practical, thinking about how to raise the baby in the Fairy Tail guild environment. The guild members would be overjoyed and offer all kinds of help, like Happy bringing little gifts for the baby to be.
One idea could be that Natsu and Lucy accidentally end up taking care of a baby dragon. Natsu would be excited to teach it fire - breathing tricks while Lucy would be more focused on keeping it safe and fed. Another plot could involve a magic spell gone wrong that turns them into babies themselves, and they have to figure out how to reverse it while in this state. It could also be a story where they find a lost baby in the forest during one of their quests, and they decide to raise it together, which would show their growth as characters in terms of responsibility.
