Determined is how Ryuku described the women before him. It was often said that the straightest path was a straight-line and certain martial arts certainly reflected this attitude. Kaiu's approach was resembling that straight-line mentality. Green eyes watched her, but his senses were spread wide and he was aware of his surroundings, straight often meant deception when coupled with his opponents weaponry.
She carried a Wakizashi, but he did not see a Katana, it could mean several things. But, coupling the short-bladed weapon with Kunai and the stealthy approach she used earlier severely limited down the things that Ryuku thought she could be, top among them being a classically trained Shinobi, second being a common assassin that simply favored the orient style of weaponry.
Her actions, while certainly fast, were something that Ryuku could deal with in several ways. Their placement, he assumed, was also no accident. She was trying to force him to dodge a very specific way, likely a set-up for something else. He would not be moved so easily, the higher ground afforded many advantages in combat. Just as quick as the smaller women Ryuku moved his white-wood staff in the proper defense. His right foot slid back and he dropped his center of gravity by lowering his body. In this way he presented only the left side of his body to her and kept himself behind his staff, left foot never moving as his right came in line behind it, weight evenly distributed. The Qi in him continued the process of building, and already aligned with the element of air he would wait for the opportune moment to unleash any of his Qi techniques.
The shift in stance brought him out of harms way of all three kunai with maximum efficiency while placing him in a stance that he could easily change should he need to adapt to a follow up attack. He had no way of countering effectively at the moment, any technique he used he was sure could easily be evaded. No, either they would play the game of him avoiding her ranged attacks; or she would try to make her way to even ground, in which case Ryuku would certainly try to stop her by using whatever advantage presented itself.
“Come now, child.” He said as the Kunai sped by, his eyes following her every movement. “Are we to play cat and mouse?” His tone was not mocking, nor overly preachy. It was an inquiry stated in the same neutral but polite tone he has used before.
