In a pregnant storyline, Natsu could develop a deeper understanding of family values. He grew up without his real parents, so this would be a new experience for him. He'd learn about the importance of being there for his partner and child. Cana, being a strong - willed woman, would become more vulnerable yet also stronger in a way. She'd have to rely on Natsu more, which would strengthen their bond. And she'd start to think about how to pass on her own values and knowledge to the baby, which could lead to some self - reflection and growth in her character.
Natsu would likely develop into a more responsible and caring character. His protective instincts would be on high alert. He'd probably become more serious about providing for Cana and the unborn baby. For example, he might take on more difficult and high - paying missions to save up for the future. Cana, she would become more nurturing. Her usually carefree attitude might change as she focuses on the well - being of the baby. She might also start to see Natsu in a new light, as a reliable partner for this new chapter in their lives.
In this fanfiction, Natsu could start to show a more mature and caring side towards Cana. He may become more attuned to her needs, like making sure she has proper food and rest. Cana, in turn, might grow in confidence as she prepares to be a mother. She could also become more assertive in protecting her unborn child from any potential threats in their magical world.
One plot idea could be that they accidentally find out about the pregnancy. Natsu, being his usual impulsive self, is at first shocked but then becomes extremely protective. Cana, on the other hand, is a bit more hesitant as she's not sure how to handle this new situation while still being part of the guild. They could face challenges like dealing with the guild's reactions, some of which might be positive and some negative. And they have to prepare for the arrival of the baby together, which includes finding a proper place to live and getting the necessary supplies.
Their relationship would likely become more tender. Natsu would probably be more protective of Cana, always making sure she's safe and comfortable. Cana, on the other hand, might rely on Natsu more for emotional support.
Natsu would likely develop a more serious and responsible side. He's always been a bit of a hot - headed adventurer, but with Kagura pregnant, he'd need to think about protecting his family. For example, he might take on less dangerous quests and focus more on providing for Kagura. Kagura, on the other hand, could become more nurturing. She's a strong fighter, but now she has to think about the life growing inside her.
Natsu would likely become more responsible. He might start to take on more jobs around the guild to earn extra money for the future of his family. His carefree attitude would be tempered with a sense of duty. Wendy would develop a stronger sense of self - worth. In the past, she may have felt like she was just a young and inexperienced member of the guild. But now, with a new life growing inside her, she realizes her importance not just as a dragon slayer but as a mother - to - be. This new - found self - worth would make her stand taller and be more vocal in the guild, advocating for herself and her unborn child.
One way the storyline could develop is by having them face challenges related to their different natures. Hulk's uncontrollable rage at times and Caiera's more composed self might create some tension during the pregnancy. For instance, Hulk might accidentally cause a dangerous situation due to his lack of control, and Caiera has to calm him down.
The storyline could develop with them facing some sort of threat to the pregnancy. Maybe an enemy from their past resurfaces, seeing the unborn child as a way to get revenge. They would then have to fight to protect the pregnancy.
The reaction of their families could be quite diverse. Natsu doesn't really have a traditional family, but his friends in Fairy Tail are like family. They would be excited and probably throw a huge party. Cana's father, Gildarts, has been absent for a while. But when he hears the news, he might feel a mix of emotions. He could be happy that Cana has found love, but also a bit sad that he hasn't been around more. However, overall, the Fairy Tail guild would embrace their union and make them feel special and loved.
The plot could develop with Natsu and the girl initially in shock. Then they might start making plans for the future, like finding a place to live. Natsu could also try to earn more money for the upcoming baby. Their friends would likely get involved, some offering help and others maybe being a bit skeptical.
A unique way for their relationship to develop is through a shared discovery. Let's say they find an ancient and mysterious magic artifact. They both are intrigued by it and decide to study it together. As they research, they learn more about each other's interests and dreams. They might also face some dangerous situations related to the artifact, like it attracting some dark magic creatures. Surviving these situations would make their bond stronger and their relationship more complex as they now have this shared secret and adventure.
