A cut appeared in Roval's face—right below his eyes. Talia actually aimed for Roval's eye through the opening on his helm but thanks to Roval's unusual reaction speed, he was able to look slightly upwards—allowing Talia to miss his right eye.
That said, because of Talia's wiggly sword technique, the cut on Roval's face even reached up to his nose—consequently increasing the amount of blood that burst in his face, which, in turn, momentarily blinded Roval's right eye.
That said, Roval did not stand idly anymore. He dashed to his left—away from where Talia went pass through him. This way, even if Talia has a follow up attack, he would have a sufficient space to defend or counter attack.
Well… At this moment, Talia simply stood on guard after miraculously dodging Aldo's follow up attack—that came after Roval's first strike earlier.
