It has been announced that a new TV anime series, "Ascendance of a Shosetsuka ni Naro," based on the popular light novel "Ascendance of a Bookworm: I'll Do Anything to Become a Librarian," which is published on the novel submission site "Let's Become a Novelist," will be produced and will be broadcast nationwide on the Yomiuri TV and Nippon TV networks every Saturday at 5:30 pm from spring 2026. It will also be broadcast on TOKYO MX. The anime will be produced by WIT STUDIO, which has produced "SPY×FAMILY" and "Attack on Titan Season 3."
It was announced at the event "Anime Expo 2025" held in Los Angeles, USA. Yoshiaki Iwasaki will be the director, Mariko Kunizawa will be the series composer, Aiko Minowa will be the character designer, and Michiru will be the music composer. A teaser visual and teaser PV featuring the main character, Rozemyne, have been released.
Miya Kazuki, the original author, commented, "The TV anime "Ascendance of a Bookworm: The Lord's Adopted Daughter" will be broadcast nationwide and in the evening slot! I was really surprised when it was decided. I hope the whole family, including children, enjoys it. The teaser visuals and PV have been released. When I first saw the teaser visuals, I was taken aback by the beauty of the blessing. The image is of Rozemyne, who has become the head of the temple, performing a star-knot ceremony. It is a blessing from the supreme gods, the husband and wife gods of darkness and light, but don't you think it's wonderful that this dark blessing can be portrayed so divinely? It's black, but it's not sinister! Because of that, I think Rozemyne is portrayed as a very saintly maiden. If you watch the PV, you can get a good feel for the atmosphere of the anime. What do you think of Rozemyne who has become an aristocrat? Isn't she cute? Of course, the aristocratic district is depicted, but the flashbacks also show the state of the downtown family and the temple workshop. The aristocratic society where magic is all around is beautifully animated. Please watch the PV carefully and look forward to the broadcast in spring 2026."
Iguchi Yuka, who plays Rozemyne, said, "Aaaah! Sorry to have kept everyone waiting!!! The new anime series is starting!!! We recorded the PV the other day, and the images are so beautiful! New characters that we've been waiting for will also be appearing one after another! I'm so excited! The story moves from the working town to aristocratic society. I will put my heart into playing Rozemyne as she grows. I hope you will all enjoy it!"
Show Hayami, who plays Ferdinand, said, "As Rozemyne, the lord's adopted daughter, Myne steps into the raging torrent. It looks like Ferdinand's headaches will only increase (laughs). As an actor, I find the scenes where his emotions fluctuate more enjoyable, so I welcome them. Please look forward to the anime."
The work is a light novel written by Kazuki and illustrated by Shiina Yu. The story follows Urano Motosu, who lives in modern Japan, as she dies on the day she is confirmed to be working at a library, and regains consciousness as Myne, a young girl in another world ruled by nobles with magical powers, as she struggles to get a book. The first season of the TV anime aired from October to December 2019, the second season from April to June 2020, and the third season from April to June 2022.
