Shiogane Kyouko

Kitchen staff leader of Fuuryuuan. A strong-minded and confident woman who plays the role on an elder sister. She hates being called by her last name, so Naoki and the rest call her "O-Kyoto-san".
She keeps calling all of the part-time workers of Fuuryuuan "Rookie No.*" whilst they are working there for part-time job since they usually keep hiring and quitting from one minute to the next because they can't stand the hard work.
