Zenjuurou Oofujiwara

Naeka and Kousuke's wealthy & doting grandfather. Concerned that both his family line is in danger, and his surviving grandchildren might disgrace them, Zenjuro hires the two maids to ensure their safety, as well as the Fujiwara fortune. He commissioned an expensive lounge just to watch his granddaughter's kendo match and closed school for a day, showing the kind of vast influence their family has.
