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.
Another plotline could be a dream - like or alternate reality scenario. Ichigo finds himself pregnant in this alternate world and has to figure out how to get back to his normal state while also dealing with the emotions and challenges that come with the pregnancy. This allows for exploration of Ichigo's character in a new and strange situation without delving into inappropriate territory.
Another plotline could be based on a prophecy. There could be an ancient prophecy that foretold of a union between Salazar (through some form of time - traveling or magical reincarnation perhaps) and Harry that would result in a special child. The story could then focus on how they deal with this unexpected situation, trying to understand the prophecy and their new - found connection.
I'm not sure if there are any specific fanfictions that are exactly like that without inappropriate elements. Fanfiction can vary greatly. Some might focus on their friendship and how they support each other, like in a story where they have to work together to save the Soul Society again, and their bond grows stronger in a non - sexual way.
A common plotline could be that the pregnancy changes their characters. Ichigo might become more protective and responsible, while Rukia could be more nurturing. They may also have to deal with their own insecurities. Rukia might worry about being a good mother, considering her past and her nature as a Soul Reaper. And Ichigo could be concerned about providing for the family. The story could also explore how their powers and abilities are affected by the pregnancy, if at all.
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.
One possible plotline could be that it's the result of some strange magic or alien technology. Maybe an enemy uses a device on Goku as part of a plan to weaken him or create chaos. Another could be a more comical take where Goku accidentally ingests something that causes this unusual situation.
One possible plotline could be a more metaphorical 'pregnancy' in the sense of Orochimaru creating or nurturing a new and powerful jutsu or experiment that is like a 'baby' to him. It could show his obsessive nature in a different light, as he devotes all his time and resources to this new creation.
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.
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.
One possible plotline could be centered around the friendship aspect. Harry, Hermione, and Ginny might be worried about how their friendship will be affected by the pregnancies. They could work together to ensure that they still support each other through the changes. Another could be about how the wizarding community reacts. Maybe there are some old - fashioned views that they have to deal with, but they prove everyone wrong by handling the situation gracefully.
Well, it could be that Sasuke and Sakura are on a journey when they find out about the pregnancy. They then have to find a safe place to stay. Along the way, they meet different people who either help or hinder them. Meanwhile, they are also having deep conversations about their relationship and what kind of parents they want to be. They might also be worried about passing on their ninja skills and the burdens that come with it to their child, and how they can raise the child in a more peaceful world.
