Rukia had yet to build a database of her own, so she could not "know her enemy." But her daily training allowed her to better "know herself."
After all, under the training regimen she had set for herself, each day she became stronger than she had been the day before.
If such strength could not be fully controlled, it might instead become her weakness.
After arriving at an open area, Rukia drew her Zanpakuto and began her own training.
