Katsuo produced a quick nod by way of a reply, going through his mind the various places he now had access to. He thought about heading to the fitness room for a moment, if only because his own sense of irony found it hilarious. Katsuo wasn't exactly a social man though, so as funny as it might have been to slowly drain the health away from those futilely seeking to extend their own he opted against doing it too much. His mission was important, but to succeed in his holy quest he couldn't get thrown out of his home now could he? So in lieu of making everyone in the complex sick, he decided to keep his cover as much as possible...though the way her assistants kept reacting it would be difficult to do that much longer.
Examining the key he rolled the trinket over in his fingers before placing it in his pocket, standing up to give her a polite bow. His detectives had tracked down Kumiko to some business here called Ad Gustum, no doubt an establishment catering to the finest of clientele, probably some sort of art gallery or something. He doubted he needed to bring up the matter to Miss Vostrikova however, nor did he really feel the need to tell her anything more about his life than his name and when he would be paying her. There really was no further need for idle chit chat, and Katsuo was certainly not going to be the first to supply it. "That will be all Miss Vostrikova, and once more I humbly thank you for your time and services."
Walking over to her door he said one last thing before leaving, "And please, the proper term is Mr. Watanabe."
