Yes! Her (admittedly pilfered) technique had, along with the kids' bombardment, provided an opening.
Throwing her arm out to the side, her aura condensed into a golden
Diamond Fang. Rushing forward, she seemed primed to strike the knight, but suddenly stopped, flowing into a kata of some sort... though an observer could be forgiven for mistaking it for a dance. As her blade sliced through the air in front of her, spikes of energy launched from it at the knight. This move, her
Diamond Dance required some setup--an opening, but when those spikes hit, they would not only embed themselves, but...
...explode afterwards.
As her little 'dance' came to a close, she held her Diamond fang in a high stance, ready to press the attack if need be.
