Sakurako is the younger twin who is quite different from her identical sister. She is extremely cheerful, optimistic and outgoing. She thinks very highly of herself and loves her sister very much. Despite her optimistic nature, she is one of the main reasons of her sister's pessimistic nature as she discourages her with her words even though she does it out of concern about her sister's well-being. She also has a crush on Shizuka. (Source: xxxHOLiC Wiki)
