Shirayuki♀

Shirayuki loves to cook, especially for her brother, and is always trying out new recipes for him. She refers to herself in the third-person as "Hime" (姫), which translates to "princess". This might be because of her name's Western variant: Snow White. She also frequently ends her sentences with the phrase "desu-no." She addresses her brother as Nii-sama (にいさま), which is shorter than Sakuya's, but polite. In English, she calls him "Elder Brother".
