One possible plot could be that Hiei is on a mission in Kagome's world and they end up teaming up against a common enemy. During this time, they grow closer and fall in love. The pregnancy then comes as a shock, not only to them but also to those around them. They have to figure out how to balance their new relationship, the upcoming baby, and their duties in their own worlds.
Obviously, the two main characters are Hiei and Kagome. Hiei is often portrayed as a powerful and somewhat brooding character, while Kagome is a strong - willed girl with her own set of powers. Their different personalities and backgrounds would create a lot of interesting interactions in this fanfiction.
Yes, there might be some out there. Fanfiction websites often have a wide variety of stories. You can try searching on platforms like FanFiction.net or Archive of Our Own. Just type in the relevant keywords and see what comes up.
Well, first of all, there would probably be a lot of exploration of the relationship between Kagome and Hiei. Since they are from different backgrounds (assuming they are from different fictional universes), there would be cultural clashes or differences in how they view pregnancy and family. The story might also delve into the physical and emotional changes Kagome experiences during the pregnancy. And Hiei, who might be initially unprepared for fatherhood, would have to learn how to be a supportive partner. There could be scenes of them preparing for the baby's arrival, like setting up a nursery or getting baby supplies, all while dealing with any external threats or internal relationship issues.
One idea could be that in this fanfiction, their pregnancy is a result of some magical or otherworldly event. Maybe a spell gone wrong that binds their fates in this way. It could lead to a lot of character growth for both of them as they navigate the unexpected situation. Hiei, who is usually so stoic, might struggle with the newfound vulnerability and responsibility, while Kagome, being more nurturing by nature, tries to ease him into it.
If there were such a fanfiction, the implications would be far - reaching. Firstly, it would change the power dynamics between Sesshomaru and Kagome. Their relationship would become more complex due to the pregnancy. Socially, within the fanfiction world they inhabit, it would likely cause a scandal or at least a great deal of gossip. Emotionally, both characters would have to face new feelings and responsibilities. Sesshomaru, who is often aloof, would need to come to terms with being a father, and Kagome would have to deal with the consequences of having a child with a demon in a world that may not be fully accepting. Also, the story would have to deal with how their families and friends would react to this unexpected union and pregnancy.
The relationship could become more intimate on an emotional level. With the impending arrival of a baby, they would need to rely on each other more. Hiei might open up more about his feelings and fears, and Kagome would be there to support him, strengthening their bond.
Perhaps the plot could involve them preparing for the baby's arrival. Inuyasha would try to become more responsible, like finding a safe place for Kagome to stay during her pregnancy. Kagome could use her knowledge from her time to make things like baby clothes or cribs in a more modern way. And they might go on a journey to find special items or powers that could protect the baby from any harm that might come its way.
One idea could be that their relationship starts as an unexpected alliance against a common enemy. As they spend more time together, they gradually develop feelings. When Kagome discovers she's pregnant, it could bring a new level of complexity to their relationship. Sesshomaru, being a proud demon, might initially struggle with the idea of impending fatherhood but then grow into a protective and loving partner.
One possible plot could be that they are brought together by some strange supernatural event that causes Botan to become pregnant. Hiei, being his usual brooding self, might initially struggle with the idea but then gradually grow to accept and protect Botan and their unborn child.
I'm not sure if there is a specific fanfiction exactly like that. Fanfiction can cover a wide range of scenarios and pairings, but this particular one might be a bit unusual considering the nature of the characters in the original story. You could try searching on major fanfiction websites to see if such a story exists.
