Rylee was able to dodge his strikes, which was impressive in and of itself, but it bought her only a few seconds. She dodged backwards, meaning she gave up some of the precious space she had in this room. One more move like that and her back would be against the wall, no more dodging. Killing her was now simply a matter of controlling her movements. However, as Kiori's longsword thrusted forward, something strange happened. The metal bit into Rylee's flesh, but Kiori himself cringed as if he had been struck himself. Was he relieved that he had missed her vitals? More importantly, why had he missed her vitals? 

It wasn't Rylee's sunlight trick, but the assassin's momentary hesitation that allowed her to carry out the plan. It was reckless, dangerous, and impractical, but because of that the assassin wasn't able to anticipate what she was planning. Kiori made another thrust with his longsword, this time making sure he was aiming right at her vitals, but just as he was about to guide his blade into his target's chest, he felt a feeling of weightlessness. Indeed, the building was in a sorry state. The wooden planks had not been maintained, nor had the roof. Drips and drops of water had created a foundation of mold, and the recent shower left the planks soft and fragile; it was amazing the floor hadn't collapsed on them already. 

The two tumbled down, the sudden drop completely throwing off Kiori's strike and leaving a rare opening, though capitalizing on it mid-drop would require a remarkable level of agility. Still, it was not enough to shatter the assassin's concentration. He focused on righting himself and maintaining his balance as he fell. His feet touched the first floor. Good, he had control now. His legs bent as he landed to absorb the impact and his swords flew up in a defensive stance to stop any desperate strikes his opponent might throw his was. Everything was still under control. If she ran, he could catch her; if she fought, he could kill her; if she had inadvertently disabled herself, well that was that.
