At first, Kagome is likely to be angry. She's a strong - willed character, so being kidnapped goes against her nature. She would probably struggle and try to escape immediately, yelling at Koga about how wrong his actions are.
Kagome would most likely be very angry. After all, being kidnapped against her will is a huge violation. She would probably yell at Sesshomaru and demand to be released immediately.
Kagome would most likely be very angry at first. She's used to being in control of her own life and suddenly being kidnapped by Sesshomaru would be a huge violation. She might try to use her spiritual powers to fight back or at least escape.
Kagome's friends from her village might be initially shocked. They know Kagome has been involved with the demon world, but having a baby with a wolf demon like Koga is a whole new level. However, some of her closer friends might eventually come around and support her. Inuyasha, on the other hand, would probably be a bit jealous at first but might also see the potential in the baby for good in the fight against evil.
One common plot twist could be that Koga actually kidnapped Kagome to protect her from a greater threat. Maybe there's a powerful demon that's after Kagome, and Koga, despite his rough ways, believes he can keep her safe. Another twist might be that Kagome discovers she has some hidden power while in Koga's captivity that helps her either escape or gain an understanding of the demon world in a new way.
Inuyasha would probably be very angry at first. He has always had a possessive streak when it comes to Kagome. He might see Koga as a rival and try to fight him. But as time goes on, he could start to realize that Kagome is happy with Koga and, though it would be difficult for him, he might eventually back off and respect her choice.
One possibility could be a story full of drama. Maybe Kagome initially struggles with the idea of having a child with Koga. She might worry about how her friends, especially Inuyasha, will react. But as time goes on, Koga shows his unwavering support and love for her. He vows to protect their family at all costs. And together, they start to build a new life, away from the chaos of their previous adventures, focusing on the future of their unborn child.
Kagome would probably be shocked at first. Then she would start yelling at Inuyasha, demanding to know why he's doing this. She's not the type to just sit there and take it.
Another theme is adventure. Given that they are both part of a world full of demons and magic, fanfictions often send them on exciting quests together. For example, they might go on a journey to find a powerful artifact or to defeat a new evil that has emerged. This not only tests their relationship but also shows their individual strengths.
At first, their relationship might be filled with a bit of shock and uncertainty. But as they come to terms with the pregnancy, they would grow closer. Koga would start to understand Kagome's human emotions and needs even more deeply. He might start to make compromises that he never thought he would, like staying in one place for longer to ensure Kagome's safety during the pregnancy. Kagome would see a softer side of Koga and would probably fall more in love with him. Their relationship would transform from a more adventurous, somewhat reckless one to a more stable and nurturing bond.
Another theme is the struggle for acceptance. Koga is a wolf demon and Kagome is a human with her own set of values. Their different backgrounds lead to a struggle where they have to accept each other's differences in these fanfictions. For example, in many stories, Koga has to adapt to Kagome's human emotions and she has to understand his demon nature.
