Ui Hirasawa

As Yui Hirasawa's younger sister, this remarkably mature and responsible student eventually joins her sibling's high school alongside Azusa. Although she shares a striking resemblance to Yui and possesses a natural musical talent on the guitar, she is far more organized and capable with household duties. Deeply devoted to her sister's light music club, she acts as their biggest supporter and caretaker, often stepping in to help the band whenever her beloved older sister is in need.
