摘自本作简介中该角色的段落

She is a big sister who loves her little brother. Her father, Juubee, was worried about her doting on her younger brother and recommended her to study abroad. However, after being exposed to the liberal values of the U.S., much to her father's dismay, she returned home with confidence in herself and her love for her younger brother was stronger than ever. At the moment, she wears a maid's outfit to take care of her younger brother in the house. Although she has a strong image of a pampered big sister, she actually has a high IQ level and excels academically! She has a surprising side to her that is not limited to languages, but also has a talent for geological analysis and other areas. [From official site]
