Jiiya

Kaori's butler was always there, chauffering Kaori everywhere but she was more than that. He raised her, and taught her everything from how to be a lady and to how to fight with kendo. In Episode 19, when Fortune Teller Jigen frighten Kaori into thinking she was going to die, her butler disguised himself as a demon, scaring her and awakening her to the fact that dying did not mean she should lose all of her courage. It was he that encouraged her to go out and save her friends.
