One possible plot twist could be that Kagome's pregnancy reveals some hidden powers or a special connection to the spiritual world. Maybe the unborn child has a unique ability that attracts the attention of both friends and foes. For example, it could be a key to opening a long - lost portal or have the power to purify a great evil that has been lurking in the shadows. Another twist might be that Inuyasha has to face his own insecurities about becoming a father more than he expected. He might worry that his half - demon nature could somehow affect the child, leading to some internal struggles and tense moments between him and Kagome.
The plot could take a turn when it comes to the pregnancy's effect on the relationship between Inuyasha and Kagome. For instance, Kagome might become more protective and start to make decisions without consulting Inuyasha, which could lead to some friction between them. Also, there could be a prophecy about the baby that causes others in their community to act strangely towards them. Some might see the baby as a savior, while others might fear it as a bringer of doom. This would put a lot of pressure on Inuyasha and Kagome's relationship as they try to navigate through these different expectations and reactions from those around them.
One possible plot twist could be that Kagome's pregnancy is not a normal one. Maybe there are some demonic elements involved due to Inuyasha's half - demon nature. For example, the baby might have some special powers that are not typical for a human - demon hybrid. This could lead to various challenges as they try to protect the unborn child from those who might want to use its power for their own gain.
A plot twist could be that Inuyasha is forced to choose between Kagome and saving his friends. Some dark force could put his friends in danger and the only way to save them is to break off his marriage to Kagome. This would create a huge conflict for him as he loves Kagome but also values his friends deeply. Also, Kagome might come from a future where she is suddenly called back and has to find a way to either stay in the past with Inuyasha or go back to her own time, leaving him behind.
Yes, there are likely fanfics on this topic. Fanfiction often explores various 'what - if' scenarios in different fictional universes, and the idea of Kagome and Inuyasha having a baby is a popular one among fans to expand on their relationship in new and creative ways.
One possible plot twist could be that Sesshomaru initially mistakes Kagome for someone else. Maybe he thinks she's a powerful priestess from his past. This could lead to an interesting dynamic where he's initially hostile but then realizes she's not who he thought. And it might change his view on humans in general as he gets to know Kagome better.
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.
A plot twist could be that the pregnancy was a result of some sort of magical interference. Maybe a powerful enemy cast a spell on them that made Kagome pregnant, and they have to find a way to break the spell without harming the baby. Or, it could be that Kagome's pregnancy reveals secrets about her family's past that she never knew. This could lead to her having to make difficult choices about whether to continue with the pregnancy or not, all while Bankotsu is trying to support her through this difficult time.
The plot could twist when they find out that Kagome's pregnancy is progressing at an abnormally fast rate. This could be due to her connection to the feudal era and the different time - related magic there. It might also be that the baby has some special powers that are causing this rapid development. Additionally, there could be a plot twist where Koga's pack has different reactions to the pregnancy. Some might see it as a sign of weakness, while others see it as a new beginning for the pack.
One possible plot twist could be that the pregnancy is a result of some dark magic manipulation by Naraku. Maybe he had a hidden agenda all along and used some ancient spell to impregnate Kagome. This would lead to a great internal conflict within Kagome as she has to deal with being pregnant with the child of her enemy.
Miroku would probably be very supportive. He would offer his wisdom and advice based on his knowledge of the spiritual and worldly matters. He might also joke around a bit with Inuyasha about the upcoming fatherhood, like giving him some 'words of caution' in a light - hearted way. Sango would be very helpful to Kagome. She could share her own experiences of taking care of children, even if it's mainly about her younger brother. She would be there to comfort Kagome during the difficult times of pregnancy, like when she's feeling sick or moody.
He might also become more patient. Usually a bit hot - headed, but with Kagome pregnant, he'd have to learn to be more calm and understanding. For example, when Kagome has mood swings due to hormonal changes, Inuyasha would have to control his temper and be more supportive instead of getting frustrated.
