You were gathering your stuff for the day, having just completed a day of harsh training and ridicule by your instructors for being very underwhelming in the combat-section of your training. While packing up and leaving, someone quickly walked up to you, an instructor, and told you to go back to the field for another training.

You were confused, but knew not to disobey instructors, so you went out to the field and saw the Head-Mistress of the school; Nyokenshi, she was staring at you as you walked over, holding a katana in her hand and in training gear.
