Ascendance of a Bookworm Continues Its Beloved Fantasy Journey
Ascendance of a Bookworm: The Lord’s Adopted Daughter is the newest anime adaptation of Miya Kazuki’s internationally acclaimed light novel series, Ascendance of a Bookworm: I’ll Do Anything to Become a Librarian. Published by TO Books, the franchise has become one of the most celebrated fantasy light novels in Japan thanks to its detailed world-building, lovable characters, and unique focus on books, printing, and social reform.
Unlike many fantasy anime centered on battles, the series follows a young girl whose greatest dream is simply to read as many books as possible. Her passion gradually transforms the world around her, influencing everything from education and printing technology to politics and noble society.
Episode 17: “Staying Home While the Archduke Attends the Archduke Conference”
Official Synopsis
As the Archduke and his wife leave Ehrenfest to attend the annual Archduke Conference, Rosemyne remains behind to oversee various responsibilities within the castle.
Initially, she hopes to spend the peaceful days enjoying her long-awaited reading time. However, her plans quickly fall apart as she becomes overwhelmed with official duties.
Between supplying mana to the duchy’s magical foundation, practicing embroidery and noble etiquette, and managing everyday responsibilities expected of an archduke’s adopted daughter, Rosemyne finds herself busier than ever.
To make matters worse, another problem continues to trouble her.
Her grandfather, Bonifatius, who has been assigned to watch over her during the Archduke’s absence, seems to glare at her whenever they meet.
Believing that her grandfather dislikes her, Rosemyne becomes increasingly discouraged.
However, the truth is quite different.
Bonifatius has his own heartfelt reason for keeping his distance and finds it surprisingly difficult to communicate naturally with his beloved granddaughter.
A Character-Focused Episode Filled With Heartwarming Family Moments
Unlike episodes centered on political intrigue or magical discoveries, Episode 17 appears to focus on family relationships and Rosemyne’s continued adjustment to noble life.
The misunderstanding between Rosemyne and Bonifatius highlights one of the series’ recurring themes: many conflicts arise not from malice, but from poor communication and differing perspectives.
Fans can expect emotional yet humorous interactions as both characters slowly begin to understand one another.
Who Is Bonifatius?
Bonifatius is one of Ehrenfest’s most respected nobles and a legendary knight known throughout the duchy for his overwhelming strength and unwavering loyalty.
Despite his intimidating appearance and stern expression, he deeply cares about his family.
Unfortunately, his lack of social grace often makes him appear frightening to those around him—including Rosemyne herself.
Episode 17 is expected to explore this softer side of Bonifatius, giving viewers a better understanding of one of the series’ most beloved supporting characters.
Rosemyne’s Noble Life Becomes More Demanding
Since becoming the adopted daughter of the Archduke, Rosemyne’s daily routine has changed dramatically.
Instead of spending her days creating books, she must now balance countless responsibilities, including:
- Supplying mana to Ehrenfest’s magical foundation.
- Studying noble etiquette and customs.
- Practicing embroidery and other aristocratic skills.
- Managing printing-related projects.
- Strengthening relationships with influential noble families.
Although these duties often keep her away from the books she loves most, each experience helps prepare her for the important role she will eventually play within Ehrenfest.
The Story So Far
The story follows Urano Motosu, a university student whose greatest love is books.
After dying in an accident, she is reincarnated into a medieval fantasy world as a frail young girl named Myne, where books are rare and only available to nobles.
Determined to read again, Myne decides to create books herself.
As her extraordinary magical power begins attracting attention, she eventually hides her commoner identity and becomes Rosemyne, the adopted daughter of Ehrenfest’s Archduke.
Now living among nobles, Rosemyne continues pursuing her dream while protecting her family, friends, and the future of the printing industry she helped create.
