A young-looking silver-haired girl who Yuzu befriends in the Tokyo Train Station after they both miss a train (coincidentally, to the same place, Kyoto). Sara believes in things such as fate and soul mates, and as such believes she and Yuzu were "destined to meet". She had previously met Mei and had a crush on her, and as such dated her briefly, but gave up on her so that Yuzu and Mei could be together. Before finding out they were in love with the same person, Sara supported Yuzu to confess her love. She is Nina's older twin sister, despite looking younger.
