Ascendance of a Bookworm Season 4 Confirmed for April 4 Premiere; New Visual and Trailer Drop

Concrete details for the next installment of Ascendance of a Bookworm have finally arrived. Season 4, officially titled Adopted Daughter of an Archduke, is set to premiere on April 4th. The announcement confirmed the release date alongside a new key visual and the main trailer.

This new season adapts Part 3 of Miya Kazuki's light novel. The story focuses on Rozemyne's integration into the highest ranks of noble society following her adoption by the Archduke. The trailer highlights Rozemyne in her new noble attire, shows Ferdinand observing her, and teases sequences involving magic trees and the Night of Schutzaria.

Animation duties remain with WIT Studio, the team behind recent hits like SPY×FAMILY. Little Glee Monster is handling the opening theme song, "Pages," which is featured in the new promotional video.

Staff returning includes Yoshiaki Iwasaki directing and Mariko Kunisawa handling series composition. Author Miya Kazuki noted that the new visual showcases Rozemyne's updated wardrobe, a significant change from her previous High Bishop look.

Yuka Iguchi continues to voice the determined protagonist, while Sho Hayami reprises his role as Ferdinand.

Broadcasts begin on Yomiuri TV and NTV on Friday, April 4th, at 5:30 p.m. JST. TOKYO MX will follow two days later. Reports indicate this run will cover two consecutive cours, confirming a half-year commitment. Crunchyroll streamed the previous three successful seasons.
