Rukia was impressed that he was able to move out of the way so quickly. She smirked and tucked her sword away. "I was just getting started" she said casually.
She positioned her fingers just so, hand resting on her arm, one arm outstretched. "Hadō number 31. Shakkahō!" As she spoke the words, a red ball of light appeared at the palm of her hand, growing slightly larger with each word. And then, she released it, the red fire ball blasting its way towards Klaus. If she had said the full incantation it would have been much stronger but she would build up. Test him.
