adieu has two active music credits in 2026: the ending theme "Wanna me" for the second cour of Ascendance of a Bookworm Part 3, and the theme song "Sasakure" for the anime film We Are Aliens, which opens in Japan on September 25.
adieu, the singing name of actress Moka Kamishiraishi, entered 2026 with a pair of theme song credits. The earlier came first: in late May, the staff of Ascendance of a Bookworm Part 3 announced that adieu performs "Wanna me," the ending theme for the second cour, with Satoko Shibata writing both lyrics and music. The CD single was set for July 29, and a limited first pressing bundles a Blu-ray of adieu's 2025 concert.
A month later, the third promotional video for the second cour put the song in context: "Wanna me" debuts in the video and starts airing with the episode on July 11, sharing the music bill with Kana Nishino's opening theme "Power of Love." The second cour premieres July 11 on Yomiuri TV and the Nippon TV network at 5:30 p.m. JST, part of a half-year run that began April 4 under director Yoshiaki Iwasaki at Wit Studio.
By September the coverage moved to a different production. A theme song trailer for the We Are Aliens anime film, streamed by NOTHING NEW, previewed "Sasakure," a portion of the song not previously made public. Director Kohei Kadowaki helmed the video. The film opens in Japan on September 25 and stars Ryota Bando and Amane Okayama as the young adult leads, with Yuto Maki and Tasuku Nakagome voicing younger versions.
Across the three stories, the pattern is steady: adieu supplies theme songs for two separate productions in the same year, one a continuing television run and one a film. The Bookworm announcements settled the song, its writer, and its release; the trailer is where the We Are Aliens theme first became audible.
