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.
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.
The relationship would likely become more intense. They would have to rely on each other more, and their bond would deepen as they are about to become parents. Inuyasha would probably become more protective of Kagome.
One possible plotline could be Kagome and Inuyasha preparing for the arrival of their baby. They might face challenges like finding a safe place to live in the feudal era. Inuyasha would be extra protective, using his demon strength to keep Kagome and the unborn child safe from any threats, be it other demons or the perils of the wild.
Inuyasha would likely become more protective. He's always been protective of Kagome, but with her pregnant, it would be on a whole new level. He might not let her go on dangerous missions as easily. Kagome, on the other hand, would probably get frustrated with his over - protectiveness at times, but also appreciate his concern deep down.
Perhaps the plot could involve the initial shock and confusion for both Kagome and Sesshomaru. They'd have to deal with the social and personal implications of this unexpected situation. Maybe they'd try to keep it a secret at first, but as the pregnancy progresses, it becomes harder to hide.
There might be some out there. You could try searching on fanfiction - specific websites like Archive of Our Own. Just type in the relevant keywords and see what pops up. However, this is a rather unusual and creative concept for a fanfiction.
Some fanfics might focus on Kagome's pregnancy journey. She could have difficulties due to the unique circumstances. Maybe her powers are affected during the pregnancy, or she has to deal with cravings that are a result of the combination of her human and the spiritual energy in her. Inuyasha, on the other hand, may struggle with how to protect her and the unborn child from his enemies who might see this as an opportunity to harm him.
Well, perhaps in the fanfic, the pregnancy could be a catalyst for Inuyasha and Kagome to bring their two worlds closer. They could start to work on making a place where their child can grow up safely, which means mending relations between demons and humans in their area. And of course, there would be the whole aspect of Kagome's pregnancy journey, like her changing emotions and physical needs.
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.
