"First published in Japan in 2017 by TO Books, Tokyo"--Colophon.

The long winter comes to an end and vibrant spring returns to Ehrenfest. The temple swirls busily as attempts to control Myne's future escalate and the High Bishop, fueled by hate, shrouds the city in the darkness of his nefarious plots. But Myne just wants everything to stay the same. Her little brother has been born, she's making new books thanks to her progress making ink, and she wants nothing more than to just keep spending more heart-warming time with her family and friends. The world, however, forces her to make a cruel and unbearable decision. To protect those she loves, she must begin walking a new road. Part two of this biblio-fantasy concludes in this heart-wrenching volume! There's a collection of short stories following the shocking climax, as well as two completely original short stories and a four-panel manga drawn by You Shiina.

Rozemyne awakens from her two-year sleep to a world that isn’t as she remembers it. The strange sensation fills her with unease, but she has no time to rest—she is soon to be enrolled in the Royal Academy as an archduke candidate, where she will be taught how to control her mana, make magic tools, and perform the magic needed to rule as an archduke. She begins dormitory life with colorful teachers and students from other duchies, aiming to be the best big sister possible... but there is little chance things will go according to plan when there is a massive library on the premises. She charges there at once, the other archduke candidates and even the royal family disappearing from her mind entirely. She truly will do anything for books! Now begins a new chapter of this biblio-fantasy, with a school as its setting! This volume includes two original short stories, a four-panel manga drawn by You Shiina, and the results of the second popularity poll.

Myne successfully negotiates with the temple to become an apprentice blue shrine maiden, ensuring she will receive the same treatment as a noble. Her work there begins, and after such a long wait, she can finally read in the book room! But the temple's status-based structure and her problematic attendants mean she doesn't have it easy: she'll need to beat society to enjoy her books in peace! This is a biblio-fantasy by book lovers, for book lovers! Part 2, begin!

Myne has finally started to adjust to her new life... but once a bookworm, always a bookworm. As winter sets in, there are historical methodologies to try: papyrus, clay tablets... anything that can hold letters and words. Even if it means getting well enough to visit the forest! But first there are chores to do and mythical fruits to cook. Fortunately, Myne has an ally in Otto, her father's paperwork-swamped colleague. Can he teach her how to read and write in this world and put her to work somewhere that will advance her goals and status? Or will she be stuck as a poor, illiterate girl forever?

Spring is the season when love blooms! Rozemyne's retainers are bursting with energy as they make clothes, attend their debuts, and shine in the new season. The improved printing press is finally completed in the temple workshop, and the variety of available books is steadily beginning to expand. Picture books, collections of sheet music, knight stories—all are now being sold. Their first aim is to further develop the paper-making industry in preparation for the spread of printing across the entire duchy. To this end, Rozemyne's party travels to Illgner, hoping to teach them how to make paper while also researching new materials to use. As the environment around Rozemyne slowly improves, the archduke's older sister arrives for a visit, shrouding Ehrenfest in an air of unease. Everything changes in this volume of this biblio-fantasy as nobles emotionally clash and the conclusion of Part 3 approaches! Including two newly written short stories and a four-panel manga drawn by You Shiina!

Myne makes progress with her book-making endeavors, all so that she can read them herself. Her sickness turns out to be the Devouring after all, and she learns that curing herself will cost a lot of money. She ultimately decides to keep living as she has been thus far, selling her knowledge from Earth to make money. But despite her enthusiasm, the Devouring eats away at her more by the day, until she ends up collapsing in the middle of a business meeting. This is a biblio-fantasy, by book lovers, for book lovers!

"An immense display of mana in front of the Knight's Order has earned Myne the attention of nobles. The result? Yet more people appear, hoping to exploit the young apprentice shrine maiden's value. And so the High Priest decides to shelter Myne in the temple to safeguard her from the impending danger he forsees. But Myne's main concern is still books and she works to advance the printing process so that their price will fall and more people can buy them. Her long winter in the temple away from her family begins, but everything changes as the harsh winter passes and the spring nears, offering a glimpse into what the future holds."--Back cover.
