雪ノ下 陽乃

Yukino's older sister and a former student of Soubu High School. Despite being a college student she spends a good deal of time spying on her sister's life. According to Hayama, she’ll meddle so much with what she likes to the point of killing it. For the things she hates, she’d go the extra mile to crush them. She aimlessly travels during her days-off. Her being beautiful, rich, and charismatic makes people (including the series' audience) only see her good side, defer to her and ignore big problems she causes to others.
