One common theme is the struggle between loyalty and newfound love. Kagome has an existing relationship with Inuyasha, and Koga is an outsider. So, many fanfictions explore how Kagome deals with her feelings for Koga while still being tied to Inuyasha in some way.
Another theme is the cultural differences between them. Koga is from a different tribe, and Kagome is from the modern world. Fanfictions often play with how these differences can create both challenges and interesting interactions in their relationship. For example, Koga might not understand some of Kagome's modern ways, and Kagome might be fascinated by Koga's tribal traditions. This can lead to a lot of character development and romantic tension.
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.
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.
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 common theme is the love triangle aspect, with Inuyasha also in the picture. It often explores how Koga tries to win Kagome over despite Inuyasha's presence. Another theme could be adventure, as they are both part of the Inuyasha universe which is full of quests and battles.
A common theme is the forbidden love. Since Koga is a wolf and Kagome is a human, their relationship often faces obstacles. Another theme is adventure, as they usually go on various quests together.
Another theme is the development of their relationship against all odds. Since Kagome has a connection with Inuyasha in the original story, fanfics usually focus on how she and Koga overcome obstacles to be together. It could be things like rivalries or misunderstandings that they have to work through. And it makes for a very engaging read as you see their relationship evolve.
One common theme is the exploration of a forbidden love. Since Kagome has a connection with Inuyasha, her relationship with Koga is often seen as something that goes against the norm in the original story setting.
One popular storyline could be Koga and Kagome teaming up to face a new and powerful demon threat that neither could handle alone. This would test their relationship and force them to rely on each other.
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.
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.
