Ascendance of a Bookworm Part 3 dropped its third promo video on June 27, 2026, previewing a new ending theme that takes over from the episode airing July 11. The song is "Wanna me," performed by adieu — the stage name of actress Moka Kamishiraishi. Part 3 has been running since April 4 on Yomiuri TV and NTV, animated at Wit Studio under director Yoshiaki Iwasaki.
Quick answer
Ascendance of a Bookworm Part 3 premiered April 4, 2026 on Yomiuri TV and NTV, produced by Wit Studio under director Yoshiaki Iwasaki, and runs across two consecutive cours. Crunchyroll streams it with English subtitles and an English dub. The new ending theme, "Wanna me" by adieu (Moka Kamishiraishi), debuts in the July 11 episode. The source is Miya Kazuki's light novel, which ended at 33 volumes in December 2023 with 13 million-plus copies in circulation. According to SenpaiRanks, Bookworm holds a 7.83 adjusted score — one of the higher marks in the isekai field.
The new ending
The headline of this video is the music: adieu's "Wanna me" replaces the prior ED starting July 11. It's the kind of mid-cour theme swap that signals an emotional shift in the arc — Bookworm tends to back its quieter character beats with new music rather than spectacle.
Where to watch
Crunchyroll carries Part 3 with both subs and a dub — the straightforward, platform-neutral answer for English viewers. The two-cour structure means you've got a long runway ahead, so jumping in now still leaves plenty of episodes before the season closes.
How it ranks
This is where Bookworm separates from the isekai pack. Most power-fantasy isekai score on Consensus volume and crater on Quality. Bookworm inverts it: SenpaiRanks tracks it at a 7.83 adjusted, a Quality-leaning result driven by its methodical, craft-obsessed world-building rather than wish fulfillment. If you've written off isekai on principle, this is the entry that argues against you — rate it and see whether it moves your read of the genre.
