There are many fanfictions out there with all kinds of creative and often out - of - the - ordinary concepts. However, this particular idea seems rather unusual and not in line with the traditional characteristics of the Inuyasha series. In the original series, both Koga and Inuyasha are male characters, and pregnancy in a male - male relationship is not a part of the original story's biological framework. But in the world of fanfiction, writers can bend the rules and create unique scenarios, so it's possible that such a fanfiction exists, but it may not be a common or mainstream one.
For character development, the OC could be an outcast in her own community. When she enters the world of Inuyasha and Koga, she finds a new sense of belonging. Koga's wolf pack could initially reject her, but through her determination and kindness, she wins them over. Inuyasha's friendship also helps her to see her own worth. As the story progresses, she becomes a strong and respected figure, not just among them but also in the wider world of demons and humans they inhabit.
One idea could be an OC who is a powerful healer. Koga initially distrusts the OC because she's new to their world. Inuyasha, on the other hand, is more open - minded. The story could revolve around the OC trying to prove herself to Koga while also helping Inuyasha in his battles against various demons. This would create a dynamic where the OC has to navigate the complex relationship between Inuyasha and Koga.
Well, it would be a very different take on the Inuyasha universe. Since this goes against the normal biological setup, it would probably involve some sort of magic or supernatural element. Maybe there's a cursed object that causes this strange phenomenon. The story could then explore how Inuyasha and Koga deal with this unexpected situation, how their relationship changes, and how the other characters in the Inuyasha world react to it.
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.
It could lead to a whole new adventure. Their relationship might be the key to uniting different factions in their world. Since Koga has his own group and Inuyasha has his allies, the union through love could bring peace. And the kiss could be just the start of a series of events that reshape their world for the better.
It might also change the power dynamics within the groups. If Inuyasha's daughter has certain powers or influence, her relationship with Koga could shift the balance of power. Some members might see this as an opportunity to gain more power through the new connection, while others might fear a loss of their own influence.
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.
One common theme is rivalry. Since they are both powerful characters in their own right, fanfiction often explores their competitive nature. Another theme is cooperation. Sometimes they have to team up against a common enemy. And of course, there's the theme of respect. They gradually come to respect each other's strength and abilities through different storylines.
Perhaps in the fanfiction, Koga kidnaps Kagome believing she has some special power that can help his wolf demon tribe. He might think that she can heal the sick among them or bring good fortune to their land. However, Kagome doesn't actually have this power, and she has to convince Koga to let her go while also trying not to anger him too much. As she's held captive, she might learn more about the wolf demons and their way of life, which could be an interesting aspect of the story.
