The highly anticipated anime adaptation, Ascendance of a Bookworm: Adopted Daughter of an Archduke, has unveiled its teaser video and key visual, confirming a Spring 2026 premiere. This new series will adapt Part 3 of Miya Kazuki’s light novel series, promising to delve deeper into Rozemyne’s aristocratic life and her relentless pursuit of books.
A New Studio Takes the Helm
Fans will note a significant change in animation production, as WIT STUDIO, known for acclaimed titles such as Spy x Family and Attack on Titan (first three seasons), is taking over from Ajia-do Animation Works. This transition was announced in December 2023, generating considerable excitement among the fanbase.
New Talents Join the Production
Accompanying the change in studio, new key staff members have been revealed to lead the production of Adopted Daughter of an Archduke. Yoshiaki Iwasaki, known for his work on Kowloon Generic Romance, will serve as the Director. The series composition will be handled by Mariko Kunisawa, recognized for The Dinner Table Detective. Aiko Minowa is set to be the Character Designer. These new additions are expected to bring a fresh perspective to the beloved series.
Familiar Voices Return to Ehrenfest
Despite the changes in the production team, the core voice cast for key characters is set to return, ensuring continuity for fans. Yuka Iguchi will reprise her role as the indefatigable Rozemyne, while Show Hayami will once again lend his voice to Ferdinand. Their return guarantees that the established personalities of these central figures will remain consistent with previous seasons.
The Journey Continues: Rozemyne’s Noble Endeavors
The Adopted Daughter of an Archduke arc begins after Myne resolves to leave her life in the lower city and embrace her new identity as Rozemyne, the adopted daughter of Ehrenfest’s archduke. This new chapter promises a brutal initiation into noble society, replete with rigorous etiquette and magic training, alongside her existing duties as High Bishop and forewoman. However, Rozemyne’s unwavering passion for books remains her driving force, even as she navigates the complexities of her elevated status and the challenges of a world where books are scarce and highly valued.
The teaser trailer and visual for the upcoming anime were first showcased at Anime Expo 2025, offering a glimpse into the next phase of Rozemyne’s “biblio-fantasy” adventure. The light novel series, written by Miya Kazuki and illustrated by You Shiina, has amassed over 11 million copies in circulation, a testament to its enduring popularity.
