A long and stressful game began for both Rui and Kane as they participated in the battle but with only a fraction of their full exertion. They fought just enough to not be noticed for not participating, but they made sure to retain their energy reserves.
Kane didn't even bother using Void Step to try and get her with stealth. He already knew that there was no way his misdirection was working on a Martial Senior, Martial Heart or not.
Instead, he mostly stuck to occasionally trying to get her in her blind spot whenever she was pressed heavily by many of the offensive heavy hitters.
The battle slogged on and on for quite some time, however, Rui did not simply wait around conserving energy and getting in an occasional strike. He also made his sound-canceling defenses against her attacks more subtle than before, he timed it later and later, and even launched himself backward grimacing as though he had been struck or hadn't been able to cancel everything out.
