There could also be a storyline where the baby has a special connection to the Shikon Jewel. Maybe the baby is born with a unique ability to sense the jewel's power or even has the power to purify it further. This could lead to many adventures as they try to keep the jewel safe from those who would misuse it.
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.
One interesting storyline could be about a young Inuyasha and Sesshomaru being forced to work together due to a common threat to their family. They might start off hating each other as they usually do, but as they face challenges, they gradually learn to respect each other's abilities.
There could be themes like 'hidden pasts'. Maybe there are secrets about their families or their own pasts that are revealed in the fanfiction. 'Overcoming differences' is also a big one, given their different natures and backgrounds. And 'quests for special items' which can be related to their journey in the original story but with new twists in the fanfiction.
One popular story could be 'A Journey of Love' where Inuyasha and Kagome face many challenges together that strengthen their bond. They might go through a difficult battle against a powerful demon and in the process, realize their deep love for each other more than ever.
One common plotline could be Kagome and Inuyasha preparing for the arrival of their baby in the feudal era. They might face challenges like getting the necessary supplies and dealing with the reactions of their friends and foes. Another plotline could involve Kagome's pregnancy being a symbol of hope for the future, uniting different clans. For example, some clans that were previously at odds might come together to protect Kagome and the unborn child, seeing it as a new beginning for the land.
There might be a fanfiction where Inuyasha and Kagome are re - imagined as completely human from the start. In this version, they meet in a small village and their relationship develops as they work together to protect the village from bandits and other threats. They have to rely on their wits and human strength rather than any demon abilities.
Well, it could be about their journey in raising the baby. Maybe the baby has some special powers inherited from Inuyasha and Kagome. They might face challenges like protecting the baby from demons who want to use its power for evil.
They would raise the baby in a loving environment. Inuyasha, with his rough exterior but kind heart, would be a strict yet loving father. He'd pass on his knowledge of the demon world and survival skills. Kagome would bring in her modern - day values like education and respect for all living beings. They might live in a village in the feudal era, but also take trips to Kagome's modern world for things like medical care and to expose the baby to new technologies. Kagome would also make sure the baby understood its heritage, both human and demon, and how to use its powers for good.
There might be some 'Inuyasha abuses Kagome' fanfiction, but it's not something that is likely to be promoted or widespread. The original story is about their relationship growing and developing in a positive way, so this kind of negative and abusive take goes against the spirit of the original. However, in the vast world of fanfiction, it's hard to say for sure that none exists.
One popular baby Kagome fanfiction might be those that explore her early life in the feudal era. For example, stories where she is discovered as a baby by the Inu - yasha gang and how they take care of her, which can add a really cute and heart - warming aspect to the existing Inu - yasha universe.
