Cronic's hearing was given a slight boost when he got his modifications, enabling him to pick out that the ninja and her associates were heading for Kabuki harbour, but that was about it. His eyesight however, was greatly enhanced, and he promptly spotted the wire she ran on, and the rooftop she was stood on. He could try to capture her now, or at least give chase, but he knew that whoever she was, if she had companions... The odds were not in his favour if he tried to take them on alone. Who knows what kind of things she was capable of? Instead, he shifted his focus on the Shinsengumi HQ, before pulling out a cellphone, and promptly called Hijikata. Cronic began tapping his feet impatiently as he waited for him to answer.
