Urano Motosu, a young woman living in modern Japan who loves books more than anything, dies in an accident on the very day she was supposed to start her dream job at a library. Waking up with the lingering regret of wanting to read more books, she finds herself reincarnated in another world where books are extremely rare and a strict class system is in place. She has become Myne, the young daughter of a poor soldier. In this harsh environment, books are almost non-existent and commoners cannot even read. Mobilizing all her knowledge from her previous life, she struggles to create paper and ink from scratch, aiming to mass-produce books and eventually secure a position as a librarian. The story unfolds in several major parts as Myne grows and her environment changes. Life in the lower city and the origins of bookmaking: As the daughter of a poor commoner, she receives the love of her family while repeating a process of trial and error to raise funds and make books. Temple activities and mana: Myne possesses an astonishingly large amount of "mana," which puts her life at risk. To survive, she enters the temple ruled by nobles as a "Blue Shrine Maiden Apprentice" under a contract. Noble society and power struggles: Myne's overwhelming mana and modern ideas cause great ripples in noble society. Eventually, to protect her family and friends, she discards her name and life as a commoner to live in noble society as Rozemyne, the adopted daughter of the Archduke.
Obsessive passion for books: She will stop at nothing to read, starting bookmaking from zero using modern knowledge. Fatally frail constitution: She constantly collapses with fevers, requiring constant nursing and support from those around her. From commoner to Archduke's daughter: Her mana and talent catch the eyes of nobles, leading her to become Rozemyne to protect her family.
Myne's guardian: He cares for the frail Myne more than anyone, supporting her by carrying her on his back and nursing her. The only commoner who knows her secret: He realized she was someone else (Urano) inside but accepted her as Myne anyway. Growth into a capable merchant: From dreaming of being a traveling merchant to becoming Myne's personal merchant, he shows his talent under Benno. A lifelong promise: Even after Myne becomes a noble and they are separated, he promises to continue supporting her as a merchant.
Fran: An excellent and upright head attendant who deeply respects Myne and teaches her proper etiquette.
Gil: Initially rebellious, he learns the joy of work and supports Myne through the printing industry.
She serves the High Bishop as an attendant but later opens her heart to Myne and dotes on the baby.
Alisa's head attendant. Extremely cute and very polite.
The High Priest (Ferdinand) is a solitary, genius noble who guides Myne with both severity and warmth. Capable guardian: He is the first to recognize Myne's mana and modern knowledge, protecting her in the temple and noble society. Ruthless educator: He relentlessly educates the frail Myne, serving as her ultimate partner.
