Rei, Yoshinos older sister, has a tomboyish appearance and resembles a "bishounen" on the outside but is actually quite gentle in nature. She enjoys reading shoujo manga and her favorite word is sincerity. In addition to kendo, she also enjoys sightseeing as a hobby. Despite being involved in domestic arts like cooking, Rei remains obsessed with Yoshino. During the first season, Rei was known as Rosa Foetida en bouton, while her older sister Torii Eriko played the role of Yoshinos grande soeur. Shimazu Yoshino was Reis petite soeur in that season. In the second season, Rei transformed into Rosa Foetida.
