Love and relationship growth is likely a theme. It may show how their relationship evolves with the addition of a baby, like how they support each other and their new - found family unit. For example, they might face difficulties from the outside world because of their unusual family setup, but their love for each other and the baby helps them through.
One common theme could be family. Since it involves a baby, it might explore how Bankotsu and Kagome build a family together, dealing with the joys and challenges of raising a child.
Bankotsu would likely become more protective. His tough - guy exterior would soften as he has someone he truly cares about and a baby to look after. He might start to think more about the future and less about his past violent ways. Kagome, on the other hand, would become more maternal. She would be more cautious and would use her nurturing side more. She might also become more assertive in protecting her family, drawing on her own inner strength that she has developed over her adventures.
One idea could be that the baby has a special power inherited from both of them. Since Kagome has spiritual powers and Bankotsu is a strong warrior, the baby might be able to sense evil spirits from afar and also have great physical strength. This could lead to many adventures where they have to protect the baby from those who would want to use its powers for their own gain.
One possible plot could be that Bankotsu and Kagome initially face many challenges in their relationship due to their different backgrounds. Bankotsu, being from a more violent and rough past, has to learn to be gentle and nurturing. Kagome, on the other hand, has to help Bankotsu understand the modern values she brings. When they find out they are having a baby, they start to build a more stable home. Bankotsu might go on adventures to gather resources for the baby's future, while Kagome focuses on her pregnancy and preparing for the new life. The baby could also inherit unique powers from both of them, leading to an interesting story arc about protecting the baby from those who might want to use its powers.
A possible storyline is that the baby is born with a mysterious mark. This mark is prophesied to bring either great fortune or great disaster. Kagome and Bankotsu then embark on a journey to find out the meaning of the mark and how to ensure their baby's future is a positive one. They meet various characters along the way who either help or hinder them in their quest.
Bankotsu and Kagome fanfiction is interesting because it combines two very different characters. Bankotsu is often seen as a rough and tough warrior, while Kagome is more gentle and spiritual. A fanfiction could play on this contrast, for example, having Kagome's kindness soften Bankotsu's hard edges.
Another option is to look for fanfiction compilations or blogs dedicated to Inuyasha fanfictions. Sometimes, these sources curate and recommend different types of fan - made stories, and there's a chance you'll find the 'bankotsu and kagome baby' ones among them.
One common theme could be family. Since it involves a baby, it might explore how Koga and Kagome adapt to being parents and creating a family unit.
One possible fanfiction could be a story where Bankotsu, the powerful demon slayer, and Kagome, the time - traveling miko, team up to fight a common enemy. They start off as reluctant allies, but as they face challenges together, they develop a mutual respect and friendship.
It could be Naraku. Even though the focus is on Kagome and child Bankotsu, Naraku is always lurking in the shadows in the Inuyasha universe. He might see Kagome's interaction with Bankotsu as a threat to his plans and try to manipulate the situation to his advantage. He could try to turn Bankotsu against Kagome or use Kagome's distraction with Bankotsu to carry out some other evil deeds.
One common theme is the struggle between love and loyalty. Bankotsu often has his own loyalties in the original story, and in fanfiction, his love for someone might conflict with that. For example, he might have to choose between his love interest and his band of followers.
