Sachiko Ogasawara

She is a "Japanese Princess" as she comes from a family of great wealth and status. She is the eldest daughter of the Ogasawara family which makes her responsible for marrying Kashiwagi Suguru. She said that she is supposed to marry him because his family has enough influence to run their company. She is titled as the Lilian Joshigakuen's (Lilian All-Girls School) idol and star. Former Rosa Chinensis, her grande soeur, Youko, chose her as petite soeur because she wanted Sachiko to be free. Free from her family restrictions, from the expectations of others and be herself without holding back. Youko also made Sachiko quit from all of her activities such as ballet classes, lessons and such.
