Background / History

Hiyori first met Miyama Saku in a quiet public library in Kyoto. Unable to reach a book on a high shelf and unwilling to ask for help, she was assisted by Saku; the encounter became the foundation of their childhood friendship. 8

During Saku’s unexplained absence of more than two years, Hiyori received no contact from him and worried deeply about him. After recognizing him at Advanced Nurturing High School, she confronted him over the disappearance; Saku claimed that he had gone abroad to study, though Hiyori accepted the explanation only provisionally. 4

She lives in Room 504, directly above Saku’s Room 404. Shortly after their reunion, she obtained a spare key to his room from the dorm manager, exchanged contact information with him, and stated that she intended to visit frequently. 4

Appearance

Hiyori has light-colored hair that falls over her shoulders and clear violet eyes. She is usually seen carrying or reading a book, including during her first intervention in the confrontation between Saku and Ryuuen. 9 21

• Often holds a book close to her or reads during quiet moments. 19 21
• Wore gray thigh-high socks when visiting Saku’s dorm room. 4
• Her normally subdued expression becomes visibly animated when she encounters a subject she genuinely loves, particularly tea ceremony and books. 7 22

Personality

Hiyori is quiet, reserved, and comfortable with silence. She values calm environments where she can read without interruption, which is why she chose the Tea Ceremony Club over the Literature Club despite her love of books. 8

Beneath this restraint, she is emotionally direct and persistent with people important to her. She refuses to let Saku evade questions about his disappearance, worries when he neglects meals or appears exhausted, and repeatedly insists that he take better care of himself. 4 20

She also possesses a firm, independent side. When Ryuuen treats Saku as an outsider and attempts to dictate her relationships based on class affiliation, Hiyori openly rejects him despite his intimidating reputation. 21
