Obviously, Kagome and Sesshomaru's pups are the main characters. Kagome, the modern - day girl who got transported to the feudal era, and the pups, who are part of Sesshomaru's lineage.
In this fanfiction, it could be that the pups are in some sort of danger, like being hunted by a powerful demon. Kagome, with her spiritual powers and knowledge from her own world, steps in to save them. As she spends time with the pups, she starts to understand more about Sesshomaru through them. Maybe the pups are also curious about Kagome and her different scent and appearance. This encounter could also be a way to bridge the gap between Kagome's group and Sesshomaru, leading to new alliances or at least a truce in the ongoing battles in the feudal era.
Well, it's very likely. Fanfiction is a vast world with all kinds of interpretations. In a family - friendly version of this concept, the story could start with how Kagome and Sesshomaru meet and fall in love, then progress to their family life. Their pups could have unique abilities and personalities, and the story could revolve around their growth and the family's adventures together.
One possible plot could be that Kagome and Sesshomaru initially struggle to accept their new situation. But as the pups grow, they see the importance of their family. The pups might have special powers that attract the wrong kind of attention, and they have to protect them.
Well, one possibility could be that it creates a huge conflict within the Inuyasha universe. Sesshomaru's pride and his standing among the demons might be affected. Kagome, being from a different world originally, would face a lot of challenges in this situation. Her friends might be shocked and some might not accept it at first.
One main antagonist could be Naraku. He might see this union and the coming of the pups as a threat to his plans. He could try to harm Kagome or the unborn pups to disrupt any potential power shift in the demon world that could come from their existence.
Well, perhaps Kagome stumbles upon Sesshommaru's pups while on one of her adventures. Maybe she initially mistakes them for something else, like small, wild animals. Then, she realizes who they are and has to decide whether to help them or leave them be.
One possibility could be that Kagome is initially afraid of the younger Sesshomaru. In the fanfiction, she might mistake his youth for weakness at first, but soon realizes that he still has his pride and power. This could lead to an interesting dynamic where she has to re - evaluate her preconceived notions.
Kagome is a given as one of the main characters. She has her own set of friends and allies in the Inuyasha world, but in this fanfiction, the main focus would be on her encounter with Sesshommaru's pups. The pups themselves would be the other main characters. Depending on how the author writes it, there could be a lead pup among them, with a more distinct personality. And while Sesshommaru might not be present all the time, his influence would be felt through the pups. For example, they might have some of his combat abilities or his sense of dignity.
Well, Kagome could end up helping younger Sesshomaru when he is injured. This would be a big shift in their relationship as Sesshomaru is not one to usually accept help from a human. But since he is younger, he might be more vulnerable and thus more likely to accept her aid.
