Honzuki no Gekokujou Part 4 is getting a television anime. The Ascendance of a Bookworm team announced on Saturday, October 3, 2026, the adaptation of Kizoku-in no Jishō Tosho Iin, the Founder of the Royal Academy's So-Called Library Committee arc, with WIT Studio back on production.
What happened?
The news landed on the same day Part 3, Adopted Daughter of an Archduke, aired its final episode. That season premiered on April 4, 2026 on Yomiuri TV and NTV at 5:30 p.m. Japan time and ran for two consecutive cours. Crunchyroll streamed Part 3 with English subtitles and an English dub.
Part 4 still has no premiere date, confirmed cast or staff beyond the studio. What is set is the arc and the animation house: WIT Studio continues, as it did on Part 3. The official series site and Comic Natalie are the sources cited by Anime News Network.
Why it matters
Honzuki no Gekokujou, by Miya Kazuki, began in 2013 on Shōsetsuka ni Narō and the web novel ended in 2017. The print edition, illustrated by You Shiina, closed the main story at volume 33, the 12th of Part 5, in December 2023. Anime News Network records more than 13 million copies in circulation, including digital.
The anime premiered in October 2019 with 14 episodes, had a second season in April 2020 and a third in April 2022. Part 3 changed directors: Yoshiaki Iwasaki took over from Mitsuru Hongō, with scripts by Mariko Kunisawa, designs by Aiko Minowa and music by MICHIRU. Yuka Iguchi and Show Hayami continued as Rozemyne and Ferdinand. None of that has been confirmed for Part 4.
The Royal Academy arc is the stretch in which Myne, already Rozemyne, enters the noble student circuit and builds the library committee that names the part. It is the natural continuation after the archduke adoption, and one of the stretches most requested by readers following the light novel in English through J-Novel Club. The Dengeki Bunko festival the same Saturday brought other announcements, but this one came from the series team itself, at the close of Part 3.
What changes in practice?
Anyone watching Part 3 on Crunchyroll gets confirmation that the story does not stop at the end of this cours. There is still no calendar date: the team has not announced a premiere month, an opening or whether the main cast stays. Until then, the news is studio continuity, not a release window.
- Arc: Part 4, Founder of the Royal Academy's So-Called Library Committee.
- Studio: WIT Studio, again.
- Part 3: premiered April 4, 2026 and ended October 3, across two cours.
- Part 4 date: not yet announced.
