Well, it could go in the direction of Deku and the girl deciding to work together to give the baby the best life possible. Maybe Deku has to balance his hero training with preparing for fatherhood. It could also be about how their families and friends react and support them through this unexpected event. And it could show how they learn to communicate better and make decisions as a couple because of this situation.
One possible plotline could be a magical or supernatural occurrence that leads to the pregnancy in a non - sexual way. For example, a spell gone wrong or a unique power interaction.
One possible plotline could be that Hit Girl discovers she's pregnant and has to deal with the challenges of protecting her unborn child while still being involved in the fight against crime. She might have to rely on her friends more than ever and find new ways to use her skills without putting herself and the baby in too much danger.
There are very few, if any, truly family - friendly fanfics with such a concept. The idea of a character getting a girl pregnant is often part of more mature or inappropriate storylines. However, some fanfic writers might take this concept and twist it into a more positive and educational story about responsibility and growing up, but these are rare.
I'm not sure if there is a completely 'clean' fanfic with that specific plot. Fanfic can cover a wide range of interpretations and themes. However, a lot of the 'gets pregnant' type of fanfics in the Naruto fandom might tend to cross into inappropriate territory. It would be best to search in more family - friendly fanfic platforms and see if any writers have explored a more innocent take on a relationship between Naruto and Ino.
One possible plotline could be Batgirl dealing with her pregnancy while still trying to protect the city. She might have to balance her new physical state with her crime - fighting duties, and rely more on her allies.
In a Pokemon girl's journey, she might break a local rule in a Pokemon village. The village elder, who has a soft spot for her but still needs to enforce the rules, takes her aside. He tells her a story about how similar actions in the past led to problems. This story - like a 'spank' - makes her realize her mistake. And then she helps the village with some tasks as a form of making up for her error.
In this kind of fanfic, another aspect could be how Naruto's relationship with the girl changes. At first, they might have just been friends or casual acquaintances. But now, with the pregnancy, they have to build a stronger bond. They'd need to figure out their living situation, how to support the baby financially in the ninja world, and also deal with any potential social stigma that might come with having a child out of wedlock in their society.
It could work by focusing on the emotional journey. Suppose Rei discovers she has some sort of new potential or ability within her that she and Shinji see as a form of 'pregnancy'. They then go through the process of coming to terms with it, sharing their fears and hopes, and building a stronger bond through this unique situation. This way, it's about the relationship and the emotional growth, not anything improper.
There are so many great and positive fanfic themes out there, such as friendship - based adventures, heroic quests, or character backstories that are much more suitable for discussion.
A plotline could involve a time - travel scenario. Suppose Edmund and Lucy are sent to a future or an alternate time where they are older and already have families. They then have to figure out how to get back to their own time while also coming to terms with this new reality of seeing themselves as parents in the future. This can explore themes of growth and self - understanding in a unique way.
