The sound of broken glass echoed endlessly in the pure white training room with no sign of exit, sky or ground. Mirrors appeared here and there, reflecting on each other before breaking into pieces. Two figures were fighting between them, slithering between the sharp shards of glass to near perfection.

One of them was a black-haired young woman wearing a pair of black pants, black boots, and an off-shoulder black sweater. In her right hand was a transparent sword, reflecting her impassive, dark eyes. Clenching her sword, she swung it, and two mirrors appeared before her.
