One way is to think about the OC's backstory more. Why did she end up pregnant in this fanfiction world? Was it a planned pregnancy or an accident? If it was an accident, how does she deal with the unexpected situation? And depending on who the father is, it can add different layers to the story. If it's a demon, there could be all sorts of complications due to the different natures of humans and demons.
Well, first, you can focus on the OC's relationship with the other characters in the Inuyasha world. For example, how the pregnancy affects her interactions with Inuyasha, Kagome and the rest. You could also explore the challenges she faces being pregnant in a world full of demons and magic. Maybe she has to seek special protection or find a way to hide her condition from enemies.
To develop a believable Inuyasha OC, consider their motivation. What drives them? Is it revenge against a particular demon? Or perhaps a quest for knowledge? Their motivation should be clear and tie in with their actions. Also, think about their relationships. How do they interact with the existing characters? Do they have a crush on one of them? Or are they rivals? Their relationships can add depth to their character. And don't forget about their flaws. Nobody is perfect, and neither should your OC be. Maybe they are too proud or a bit too impulsive at times.
First, start with their initial meeting. It should be a bit rocky. Bankotsu is a tough character. So, the OC needs to have some sort of quality that intrigues him, like being fearless or having a unique power. Then, as they interact more, show small moments of connection. For example, the OC might share her food with Bankotsu when they are on a journey together, and he starts to see her kindness.
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.
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 way to develop their relationship is through shared responsibilities. Since the OC is pregnant, Kyoya can take on more tasks like household chores or making sure she gets enough rest. This shows his care for her. Another aspect is through emotional support. The OC might have mood swings, and Kyoya needs to be there for her. As they navigate through these new experiences, their relationship evolves. They can also have inside jokes related to the pregnancy, like when the baby kicks for the first time and they have a special way of celebrating it. This kind of unique interaction builds a deeper and more intimate relationship between them.
The OC could also develop in terms of her powers. Maybe the pregnancy enhances or alters her powers in some way. This could lead to new story arcs where she has to learn to control these new aspects of her abilities while also dealing with the physical and emotional changes of pregnancy. For example, if she has telekinetic powers, the pregnancy might make them stronger but less stable at times.
Inuyasha might decide to become a girl in fanfiction to escape the expectations and responsibilities placed on him as a male. As a girl, he could start a new life. He might join a group of female characters and learn about their ways of life. This could include learning about female - only magic or skills. The story could show his journey of self - reinvention and how he overcomes the prejudices and difficulties he faces in his new identity.
The brothers could develop in their relationships with each other. For instance, they might have to put aside their differences and work together to support the oc during her pregnancy. This could lead to stronger bonds between some of the brothers who previously had rivalries.
First, consider the role the OC will play. If it's a partner for Genos, think about their combat abilities. For example, if Genos is mainly a physical fighter, the OC could be a support with long - range attacks or healing powers.
Their relationship could start off as a bit rocky. Inuyasha might be a bit impatient with Rin's naivete at first. But as they face challenges together, like fighting off demons or finding their way through a maze - like forest, they start to respect each other. Rin would look up to Inuyasha's strength, and Inuyasha would come to appreciate Rin's kind heart.
