Ascendance of a Bookworm Part 3 Reveals Powerful New Theme Songs

The world of Ascendance of a Bookworm is expanding its soundtrack with some serious star power. As the beloved isekai series continues its half-year television run, the production committee has pulled back the curtain on the theme songs that will carry us through the second half of this journey. And let's just say, they're not playing around.

A Musical Power-Up for the Second Cour

We've just gotten a video preview of the next opening theme, and it's set to bring a new emotional charge to Rozemyne's adventures. The powerhouse vocalist Kana Nishino will be performing the opening theme song "Power of Love." The title alone suggests we're in for a track that matches the growing scale and heart of the story as our former bookworm Myne navigates her elevated status as an archduke's adopted daughter. It's a fitting metaphor for the series itself: what began as a quiet passion has grown into a narrative force of nature.

Not to be outdone, the ending theme brings its own unique flavor. Actress and singer Moka Kamishiraishi (performing under the stage name adieu) will lend her voice to "Wanna me." The song has a noteworthy pedigree, with singer-songwriter Satoko Shibata handling both lyrics and music. Fans eager to own the tune won't have to wait long; the CD single is scheduled for release on July 29. A sweetener for collectors: the limited first pressing will include a Blu-ray Disc with footage from Kamishiraishi's "adieu LIVE 2025 à la plume" concert held last September. That's what we call added value.

New Faces and Familiar Voices

While the music is new, the anime continues to build on its strong foundation. Yuka Iguchi and Show Hayami return to anchor the cast as Rozemyne and Ferdinand, their voices now synonymous with these cherished characters. They're joined by a fresh ensemble of voice actors ready to bring new figures from the archduke's world to life.

Behind the scenes, there's been a strategic shift in leadership. Directing duties for Part 3 have been taken up by Yoshiaki Iwasaki, known for his work on Kowloon Generic Romance and Hayate the Combat Butler. He steps in for Mitsuru Hongō, steering the ship at the renowned Wit Studio. It's a change of captain, but the core crew remains. Mariko Kunisawa returns to write the series scripts, ensuring narrative consistency, while composer MICHIRU is back to weave the familiar musical tapestry. The new character designer, Aiko Minowa (After the Rain), has the delicate task of maintaining the visual identity fans love while perhaps imprinting her own subtle style.

The Unstoppable Rise of a Bookworm

It's easy to forget the humble beginnings of this phenomenon. What started as a web novel by Miya Kazuki on "Shōsetsuka ni Narō" in 2013 has blossomed into a multimedia empire. The main novel series concluded in December 2023 with its 33rd volume, but its legacy is secure with a staggering over 13 million copies in circulation (including digital). That's a lot of pages, even by Rozemyne's lofty standards.

The anime adaptation has been a steady and reliable presence since its first season debuted in October 2019. This third part, titled Ascendance of a Bookworm Part 3: Adopted Daughter of an Archduke, premiered on April 4 and is airing across two consecutive cours. For international fans, Crunchyroll remains the streaming home, offering both English subtitles and dub.

Don't Miss a Page

As the current opening theme "Pages" by Little Glee Monster and the ending "Ima mo, Arigatō" by Nogizaka46's Erika Ikuta prepare to hand over the baton, it marks a new chapter in the anime's life. The transition in music often mirrors the evolution of the story itself. We're moving from one phase of Rozemyne's life to another, with all the political intrigue, magical discovery, and bibliophilic passion that entails.

So, mark your calendars for the musical shift and keep following Rozemyne's ascent. This isn't just a story about loving books; it's a testament to how far that love can take you. And now, it has the soundtrack to match its ambitious heart.
