Tōko Amano serves as president of her high school literature club. She possesses a unique ability: consuming the physical pages of books allows her to experience the stories within, treating written works as literal sustenance. This leads her to regularly request original short stories from fellow club member Konoha Inoue to use as snacks.

She has black hair typically worn in long braids, pale skin, and dark eyes, contributing to a refined, somewhat old-fashioned aesthetic. Violet is her preferred color, reflected in personal items like her umbrella.

Her background includes significant childhood trauma from losing both parents at a young age. Her father, who worked in publishing, profoundly shaped her worldview by teaching her that cherished individuals remain present through memory; this philosophy remains central to her character.

The OVA "Yume-Miru Shōjo no Prelude" depicts a pivotal moment during a visit to her deceased father's former workplace. There, she discovers discarded manuscript submissions for a writing contest. One rejected draft deeply moves her, compelling her to advocate for its reconsideration. She persuades an acquaintance at the publishing company to reevaluate it, demonstrating her commitment to recognizing literary merit and supporting overlooked writers.

Socially, her intense passion for literature creates barriers with peers who don't share her interests, causing feelings of isolation. She struggles to connect during typical social interactions but exhibits unrestrained enthusiasm when discussing books, often vividly describing imagined landscapes or literary concepts. Her father's teachings continue to guide her perspective on loss and connection.
