Benio Yonomori


Benio Yonomori is Kobeni's elder sister who has two personas: an immature and a carefree loving sister at home and the student council president at school, where she maintains her respectable popular image as a demure, well-mannered and an elegant top-performing student in front of her legion of fans. She has taken a liking to Mashiro to the extent that she would do all sorts of advances to her at home.
