4. Curiosity
[500 years ago - Feudal Era]
As the saying goes, curiosity kills the cat.
In Kagome's case, curiosity had altered her life forever.
With the defeat of Naraku all was well with the world.
She was a jobless miko, with nothing much to do in her spare time.
Shippo went to train to become a fine Kitsune youkai.
Sango and Miroku laboriously worked on making as many heirs as possible.
Her wedding and mating was in a few days.
She was terribly bored.
So she jumped into the well to visit her real family, back into the modern days.
The well never opened up again.
