Youko is the older sister of Yuji Hino, the protagonist's close friend, and holds the position of eldest among six siblings. As a college student, she also lends a hand in her family's construction company. Known for her warm and easygoing nature, she looks out for both her brother and his friend Chihiro. Her candid remark about Madoka Takatori—'weird personality, but undeniably good-looking'—perfectly captures her refreshingly straightforward character.
