Secretly a Magus and Master in the Fifth Holy Grail War, she is driven by a perfectionist nature and a competitive spirit, striving for admiration while keeping her private life hidden. As Sakura's older sister, Rin struggles with the guilt of their separation and harbors a delusion that Sakura is happier away from their family, ultimately leading her to make difficult choices during the war. Despite her tough exterior, Rin's deep care for her sister prevents her from harming Sakura, showcasing her complex emotional depth.
