Sawawa Hiyorimi (日和見紗和々, Hiyorimi Sawawa) is the live-in maid at Hime's mansion; she is also Hiro's older sister. Her cooking is recognized by Hime as the best. She is stated to have died from the bomb explosion that threw Hime into the future. In the anime, her surname is also Hiyorimi as she introduced herself to Hime. In the manga, there is not much shown of her, but she appeared more in the anime where she is often shown eating strawberry parfaits at the café. A running gag in the anime involves her sitting up in shock whenever Hiro sustains an injury that would be lethal under ordinary circumstances, only to calm down and go back to eating her parfait. She addresses Hime as "Oujo-Sama" (Miss).
