Rozemyne's slow-burn rise gets a new sound for its back half. Ascendance of a Bookworm Part 3: Adopted Daughter of an Archduke will switch to a new ending theme, "Wanna me," performed by Moka Kamishiraishi under her stage name adieu, for the second cour of its two-part run. The song is written by Satoko Shibata, with a CD landing July 29.
Quick answer
Ascendance of a Bookworm Part 3: Adopted Daughter of an Archduke premiered April 4, 2026 and streams on Crunchyroll with subtitles and dub. Its second cour gets a new ending song, "Wanna me" by adieu (Moka Kamishiraishi), penned by Satoko Shibata (CD on July 29). The season is produced by Wit Studio, directed by Yoshiaki Iwasaki, adapting Miya Kazuki's light novels. According to SenpaiRanks, Ascendance of a Bookworm holds a strong tier on the dual-axis ranking board — broadly liked and quality-consistent across its run.
The new song
"Wanna me" replaces the first cour's ending as Part 3 moves into its back half. adieu — Moka Kamishiraishi's music project — is a deliberate, mood-forward pick for a series whose appeal is its quiet, methodical warmth, and singer-songwriter Satoko Shibata writing it signals the show wants an ED that matches its tone rather than a generic tie-up single.
Production side
Wit Studio animates, with Yoshiaki Iwasaki directing this installment (taking over from earlier director Mitsuru Hongō), Aiko Minowa on character designs, and MICHIRU composing. The move to Wit for the newest run gave Bookworm a visual lift fans noticed — and the team has kept the adaptation faithful to Miya Kazuki's beloved slow-build source.

Part 3 airs on Yomiuri TV and NTV at 5:30 p.m. JST, with Crunchyroll carrying it worldwide in sub and dub. New to the franchise? This is a story you watch in order — start from Season 1. Our live release calendar tracks the weekly drop.
Where it ranks
SenpaiRanks tracks Ascendance of a Bookworm on the rankings board across both axes — its Consensus rank (how broadly liked) and Quality rank (how well it holds up) tell a more complete story than MyAnimeList's single number, especially for a slow-paced isekai that casual IMDb-style audiences tend to under-rate. Think it's the most underrated reincarnation series running? Rate it yourself and push it up the board.

Worth your queue
If you're already with Rozemyne, the new ED is a small, welcome marker that the second cour is here. If you bounced off the early pacing, the back half is where the archduke-household politics pay it off.
