At least her reiatsu was rising. That was a good beginning. She'd need to have all of that and more to be able to go up against some of the captains within Soul Society. Zhou was grinning, purple hair flying around as he moved around her, his speed truly something to be astounded by. "I was one of the youngest graduates of the Academy," he spoke, not even straining in breath even as the sword strikes continued, from a safe distance, each one a flick of lightning. "But as a true shinigami, you must be able to use Demon Arts!"
With that, Zhou would pause only for a moment as he pointed his left palm at her. "Shakkaho!" at which point, even without the incantation, a ball of red energy would form in his hand, immediately flying forth towards her. It was a low-level Demon Art, 31, but without the chant it wouldn't be a terribly potent attack. But perhaps it'd surprise her.
