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, 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.
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.
Sakura could also be an ally. As a medic - ninja, she could help Kagome if she gets injured. And Sakura is used to dealing with strange situations and new people, so she would be open to helping Kagome.
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.
Obviously, Naruto and Jiraiya would be the main characters. Naruto, the protagonist of the original series, and Jiraiya, his mentor. They have a deep connection, and any fanfiction about them meeting would revolve around their relationship.
Well, obviously Nero and Sparda are the main characters. Nero, with his white hair and his Devil Bringer arm, is a key figure in the Devil May Cry series. He's known for his brashness and his strong sense of justice. Sparda, on the other hand, is a legendary demon. He's the father of Dante and Vergil. He's a very powerful and mysterious character. In this fanfiction, their encounter would be the central focus, and their different personalities and powers would drive the story forward.
Obviously, Draco Malfoy and Dudley Dursley are the main characters. Draco, with his blond hair and aristocratic air, is a well - known Slytherin from the Harry Potter series. Dudley, on the other hand, is Harry's cousin, a rather large and spoiled Muggle boy. Their encounter would be the central focus of this fanfiction.
Most likely, Tom from Tom's world and Edd from Edd's world would be main characters. They are the central figures in their respective worlds and would probably drive the story forward when the two worlds meet.
The main characters are Yugi and Yusaku. Yugi is a character with a long history in the Duel Monsters universe. He has a group of friends and has faced many challenges. Yusaku, on the other hand, is more of a loner who uses his hacking skills in dueling. In the fanfiction, they will be the central focus as their paths cross and they interact with each other. Their different personalities and dueling styles will drive the story forward, whether they become friends, rivals, or a combination of both.
