Well, it could be about Kagome having an emotional reunion with her father. Maybe she discovers things about her family's past through him, like some hidden powers or secrets that have been passed down. And they might go on an adventure together to protect their family or the village.
It could be a demon who has a grudge against Kagome's father. Maybe her father defeated this demon long ago, and now that Kagome is in the picture, the demon sees it as a chance to get revenge on the family.
In a 'Kagome Meets Inutaisho' fanfiction, their meeting could be filled with tension. Kagome, coming from a different time and with her own set of beliefs and values, might initially clash with Inutaisho. However, as they get to know each other, they could find common ground. Inutaisho might be intrigued by Kagome's modern - day thinking and Kagome could learn more about Inuyasha's past through him. This encounter could also potentially bring about a new alliance or a deeper understanding between the two characters.
Excitement would be a major emotion. Aliza has finally met her father, so she would be thrilled. There could also be relief, especially if she has been searching for him for a long time.
Well, it could be that Aliza meets her father in a very unexpected place in the fanfiction, like in a magical forest. Her father could be on a quest there, and Aliza accidentally stumbles upon him. They then start to bond again and face the challenges of the forest together.
In a fanfiction where Kagome meets Inutaisho first, it could lead to a significant alteration in the Inuyasha storyline. Maybe Kagome's presence would influence Inutaisho's decisions. For example, if he was planning some sort of battle or alliance, Kagome's knowledge from the future (even if it's just a bit of future knowledge) could sway him. It could also create a new dynamic in the relationship between the dog demon tribe and humans, as Kagome is a human with a connection to the future and Inutaisho is a powerful dog demon.
A Kagome and Kid Hiei fanfiction encounter would likely be full of surprises. Kagome could introduce Hiei to the concept of friendship in a more open and warm way compared to what he's used to. Hiei, on the other hand, might teach Kagome some of his combat skills or his unique way of seeing the spirit world. It could also lead to a whole new adventure where they have to team up against a common enemy that threatens both their worlds.
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.
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.
The main characters are clearly Aliza and her father. Aliza is likely the central figure through whose perspective the story is told, and her father is the one she is about to meet, which will drive the plot forward.
