Yoshitake no Ane

As the short-haired, faceless elder sibling of Yoshitake, this aggressive and volatile girl shares a strained relationship with her brother. She leads a group of girls responsible for the humiliating shaving of Motoharu's beard. Despite her intimidating and violent demeanor, she harbors deep anxieties regarding her romantic prospects, particularly her unrequited feelings for Yuusuke, the older brother of Hidenori.
