Background / History

Hiyori belongs to the wealthy Shiina Family, one of the Four Great Zaibatsu. Her mother, Shiina Yuna, runs Shinazugawa Bunko and has invested much of her wealth in publishing because of her own interest in writing. Hiyori initially denies any connection to the zaibatsu when Akasaka asks, fearing that her background could change their friendship 117 535 575.

The family’s principal stronghold is in the United Kingdom. Hiyori states that it controls thirty percent of the British economy, including water, electricity, and gas, and believes its connections could protect Akasaka’s group if his political campaign fails 552.

At school, Hiyori initially feels out of place among Class C’s frequently fighting students. She cooperates with Ryuen Kakeru rather than challenging his leadership, then becomes the first in her class to discover the school’s rules and report them to him. This earns her a peaceful place within his administration as its strategist 30.

Appearance

• Hair and eyes: Her introductory scene describes black, silk-like hair. Later passages describe blue-white or silvery-white hair and violet-blue or purple eyes 30 184 340.
• Build: She is repeatedly described as flat-chested 112 127.
• Usual impression: A refined literary girl with graceful, scholarly mannerisms 183 535.
• Hairstyle: Initially uses a simple bow behind her hair. After confessing to Akasaka, she begins wearing bows beside her ears and several braids down her back 185.
• Clothing: Dresses conservatively. During a hospital visit, she wears a long blue dress, gray thigh-high socks, and white canvas shoes with red toes 791.
• Family resemblance: Her mother closely resembles her in appearance and mannerisms; her daughter Shiroha is described as a smaller version of her 184 340.

Personality

Hiyori is kind, reserved, and intensely devoted to reading. At their first meeting, she offers Akasaka 20,000 Personal Points despite having only 23,000 herself, accepting that he might never repay her because she does not want his writing to go unpublished. Her enthusiasm for his novels can overcome her usual restraint: she crowds close to him while asking for a new volume and later threatens to obstruct his publishing contract unless he supplies more books 30 38 72.

She is pragmatic without being strongly attached to status or victory. Although she disapproves of cheating, she accepts using repeated examination papers to protect her classmates. She also prefers cooperation with Akasaka over making him an enemy. After Ryuen returns, she has no interest in competing for leadership and emphatically refuses to take the position back 30 98 295 313.

Her affection for Akasaka brings out both playfulness and jealousy. She joins him in teasing Yukinoshita and Horikita, but reacts sharply to romantic provocations involving Amasawa or her cousin Mahiru. Even so, she opposes an attempt to exclude Morishita Ai from their shared circle, and eventually places her husband’s welfare above even her love of books 126 296 414 481 791.
