"Well, well... I guess our luck hasn't completely run out" Kira was also excited by the stunning discovery. They have been observing the battles taking place for a while and all that time, they have been looking for a loophole in this godlike spell of Diana, but they found nothing.
Who would have they would stumble upon the answer by beating up a comrade?
Back then they always wondered why Diana didn't use such techniques on Derik and Cyrus in the past but now they understood why. As much as Derik and Cyrus become ferocious beasts in battle, destroying everything in their path, they are also smart and watch out for openings and loopholes.
Should they find one as flawed as this, Kira was sure Derik or Cyrus will not hesitate to bath themselves with barrages of deadly attacks just to kill her. The tendency to launch suicidal attacks was just like a second nature to them and its probably rubbing off on Mason too.
