She could use her modern knowledge and skills to her advantage in the past, like using first - aid knowledge to save lives.
Inuyasha could be one of the main characters. Since he has a strong connection with Kagome in the original story, he might also be involved in the time - traveling adventure. Maybe he follows Kagome back in time or is already in the past waiting for her.
She could meet her younger self. This would be an interesting encounter as she could offer advice and guidance to her younger version. Maybe she could help her younger self to be less afraid of her powers.

Kagome could encounter other skilled fighters from different realms. They might be human - like her - but with extraordinary abilities.
