Rui had already created an anti-Fae style in all the time he had known her. This was one of the best parts of the VOID algorithm, the growths he made against a particular fighter would accumulate. He would come closer and closer to victory the more he fought against one particular fighter as the adaptive evolution of the VOID algorithm grew more and more refined and accurate.
But he yet never beaten her. This wasn't because he was too weak, they simply hadn't had a chance to fight seriously in recent times, The last time they had a serious spar was nearly a year ago, more than two of his training phases ago, a little before the winter holidays.
Although they had sparred when Rui was training the Outer Convergence technique, that was far from a real fight with many restrictions, furthermore Rui hadn't mastered Outer Convergence back then. Thus, the results of those training spars were entirely irrelevant.
