Ore to Yu Nii! anime announces Pure Heart Beat ending theme for 6 January CD
The anime has revealed its ending theme, a seven-track character-song CD and a 6 January 2027 release date.
The Ore to Yu Nii! anime (俺と悠兄！) has revealed its ending theme, “Pure Heart Beat”, along with a 6 January 2027 release date for the accompanying character-song CD. The song will be performed by Shinnosuke Tokudome as Tsubaki and Shuichiro Umeda as Yu, according to the anime’s official website.1
The announcement describes “Pure Heart Beat” as an upbeat song built around the voices of Tsubaki and Yu. The CD will include the anime version and solo versions for both characters, giving the two cast members separate takes on the same ending theme. It will also include two etude tracks, “Yōrai no Yume” and “Tsubaki e no Tegami”, taking the total to seven tracks.1
What the announcement confirms
The CD is scheduled to launch in Japan on 6 January 2027, while the television anime itself remains set for a January 2027 debut. This update does not provide an exact broadcast date, broadcaster, streaming service or international release territory.1 Those details remain to be announced rather than being inferred from the CD schedule.
The official site also lists the wider creative team: Noriko Hashimoto is directing, Yuniko Ayana is overseeing the series scripts, Studio Hibari is handling animation, and Yumi Kuroiwa is designing the characters. Yukari Hashimoto and Ruka Kawada are composing the music, with Pony Canyon attached to the production.1
Why the song matters
Character songs are a natural fit for a series whose announcement is centred on its cast, but the seven-track release also gives this update more substance than a simple theme-song reveal. The anime version should serve as the immediate tie-in, while the solo and etude tracks offer additional material for viewers who connect with Tsubaki and Yu individually.
Our opinion
“Pure Heart Beat” is a useful first glimpse at how Ore to Yu Nii! wants its central relationship to feel: bright, character-led and deliberately music-focused. The announcement stops short of revealing when audiences outside Japan will be able to watch the series, so the CD news is best treated as a promising piece of character detail rather than a wider release update. With the broadcast date and distribution plans still open, the next announcement will matter more for international viewers than the song title itself.
For now, the ending theme gives the January 2027 anime a clearly defined musical hook, while the full CD track list suggests that Tsubaki and Yu will remain central to the show’s identity beyond the episodes themselves.
