When Maki came in, Yuki stepped into her and made the opening moves of a grapple that would end with her arm behind her back.  Whether she would let him or not, he would not seal the deal.  She had shown him the counter for this, and he all but set her up for it.  This training was going to hurt before it got better, he had a feeling, but escaping from grapples was easier than escaping from ropes or cloth.
