In the 10th Carriage.
A young woman with long black hair walked into a dark forest, all on her own. This was a forest known as the Valley's Core, a place feared among the denizens of the surrounding area as the most terrifying monster field in all of Carriage 10.
The thing that made this place dangerous was the sheer variety of monsters that could be found there. It connected to many other fields, through which monsters would pour.
To be able to survive here, one had to know how to fight at least 30 different monsters and be prepared for it all. Even parties feared coming here, and the young woman had come all alone.
She turned to the right just as a large purple tiger jumped out of the trees at her, its claws as long and sharp as knives.
The woman pointed her palm toward the beast, ready to use her spell. However, her spell took far too long to activate. The tiger sliced through her chest, spilling blood all over the forest ground.
