Kakeru's cheeky younger sister, a first-year student.

Sora spends most of her spare time hanging out at her brother's apartment, often threatening to move in and sometimes making him treat her to dinner. She has a selfish side, but her dedication to her brother is undeniable. She enjoys teasing Miyako for her overly-serious demeanor and occasional slip-ups.
