Along with the broadcast announcement, the production committee has released a key visual, an official promotional video (PV), and full details regarding the opening theme song, which will be performed by the popular vocal group Little Glee Monster.

About Ascendance of a Bookworm: The Lord’s Adopted Daughter
Ascendance of a Bookworm: The Lord’s Adopted Daughter is the long-awaited continuation of the anime adaptation of Miya Kazuki’s bestselling bibliophile fantasy novel series, published by TO Books. The original novels, titled Ascendance of a Bookworm: I’ll Do Anything to Become a Librarian, have gained immense popularity for their detailed world-building, emotional storytelling, and unique focus on knowledge and books.
The story follows Myne, a modern Japanese book lover who is reincarnated into a medieval fantasy world where books are rare and controlled by the nobility. In this new arc, she lives under the name Rozemyne, having been adopted by the lord of Ehrenfest to protect her powerful mana and safeguard her loved ones.
As Rozemyne steps into aristocratic society, political conspiracies, magical dangers, and emotional sacrifices begin to surround her. Despite being separated from her family, she continues to fight for her ideals, her love of books, and the people she cherishes.
Two Consecutive Seasons and Expanded Storytelling
The announcement that the series will run for two consecutive cours highlights the production team’s commitment to fully adapting this important arc of the story. This format allows for deeper character development, more detailed world-building, and careful exploration of Rozemyne’s transformation from a temple-bound girl into a noble figure navigating high society.
For both longtime fans and newcomers, this structure ensures a smooth and immersive viewing experience.
Production by WIT STUDIO

Key Visual: “Night of Schuzeria” Brought to Life
The newly released key visual is inspired by one of the most iconic scenes of this arc, known as “Night of Schuzeria.” It depicts Rozemyne and Ferdinand standing in a forest, with moonlight reflected on water below.
Key details include:
- A magical tree bearing lyuel fruit, an important material
- Daytime flowers above and a moonlit reflection below, symbolizing duality
- Rozemyne wearing elegant noble attire, marking her new role

Little Glee Monster commented:
“We are truly happy to become one page of Ascendance of a Bookworm. We sang ‘Pages’ while imagining Rozemyne and the people of Ehrenfest living their lives with all their strength. We hope the song adds color to this wonderful story.”
