About Sei & Shimako

Name: Satou Sei
Yamayurikai Rank: Rosa Gigantea
Year: Third - Wisteria Group
About: Satou Sei, also known as Rosa Gigantea on her last year in high school, is Toudou Shimako's grande soeur. She appears to be a happy-go-lucky, somewhat tomboyish person who often flirts with Yumi. But later on the series, another side of her is shown that somehow contradicts her present personality.


Name: Todou Shimako
Yamayurikai Rank: Rosa Gigantea En Bouton
Year: First - Peach Group
About: Todou Shimako is Satou Sei's petite soeur, and the only first year who got the rank of "En Bouton" in Yamayurikai. She was first asked by Sachiko, Rosa Chinensis En Bouton, to be the latter's petite soeur, but Shimako turned her down, believing that she and Sachiko weren't right for each other as soeurs. Shimako accepted Sei's offer instead.
