Ascendance of a Bookworm Season 4: Release Date, When and Where to Watch

Ascendance of a Bookworm season 4 is finally knocking on our doors, offering Rozemyne's story a whole new chapter for anime fans worldwide. This season features an adaptation of the Adopted Daughter of an Archduke arc from Miya Kazuki's light novel series, which began as a web novel in 2013 and has more than 13 million copies in circulation. Fans have been eagerly anticipating April 4, 2026, despite the lengthy wait since season 3 concluded in 2022.

The story picks up with Myne, now living under the name Rozemyne, as the adopted daughter of an archduke. To protect the people she loves, she abandoned her life, her family, and her identity in the lower city. She now has to navigate an aristocratic environment with completely different rules while pursuing her one genuine passion: books.

When and Where to Watch Ascendance of a Bookworm Season 4

Ascendance of a Bookworm season 4 will premiere on April 4, 2026. At 5:30 PM JST, it airs on Yomiuri TV and NTV. It also airs on Tokyo MX on April 6 at 9:25 PM JST if you're in Japan and miss that window. The season consists of two consecutive cours over the length of a full half-year. Like the previous three seasons, fans in foreign countries can watch it on Crunchyroll.

What is Ascendance of a Bookworm Season 4 about?

Ascendance of a Bookworm season 4 centers on a girl who, although living in a new environment, never gives up on her passions. Even though Rozemyne is now officially a noble, beneath all the fancy titles, she is the same bookworm. In addition to trying to get more books published and into people's hands, she must manage noble relationships, engage in politics, and deal with risky plans. It never feels overly serious since it blends high-stakes drama with cozy fantasy.

The success of the series is largely due to this equilibrium. It goes beyond suspense and mystery. Every episode has a sincere regard for warmth, comedy, and story. Fans of The Apothecary Diaries or Spice and Wolf will find a lot to like here. Seeing Rozemyne navigate the noble society is a major pleasure for viewers who have been watching from season one.

Mitsuru Hongo, who directed the first three seasons at Ajia-do, has been replaced as director by Yoshiaki Iwasaki (Hayate the Combat Butler!!), who is producing the current season at Wit Studio. The music will be handled by MICHIRU again, and Mariko Kunisawa has returned to write the scripts. The new character designer is Aiko Minowo (Prism Rondo). The opening theme, "Pages," is performed by Little Glee Monster, while the closing song, "Ima mo, Arigatō," is performed by Erika Ikuta of Nogizaka46.

Yuka Iguchi and Show Hayami, who play Ferdinand and Rozemyne, respectively, are two of the returning cast members. Yukari Tamura (Rika Furude from Higurashi: When They Cry) as Georgine, Mami Koyama (Balalaika from Black Lagoon) as Veronica, Minami Takayama (Griffith from Berserk) as Florencia, Kazuhiro Yamaji (Kenny Ackerman from Attack on Titan) as Bonifatius, Nao Toyama (Uchiha Sasuke from Naruto: Shippuuden) as Angelica, Asami Seto (Mai Sakurajima from Rascal Does Not Dream of Bunny Girl Senpai) as Brigitte, and Katsumi Fukuhara (Touya Mochizuki from In Another World With My Smartphone) as Zack are the seven new cast members in Ascendance of a Bookworm season 4. With names like Tamura, Koyama, and Takayama lending the newcomers a lot of weight, the lineup is formidable.

In conclusion
