"Adrena" (Japanese: アドレナ, Hepburn: Adorena) is a song by Japanese duo Yoasobi from their fourth EP, The Book For, (2026). It was released as a single on January 4, 2026, through Echoes and Sony Music Entertainment Japan. The song serves as the opening theme for the 2026 anime series Hana-Kimi, and was based on Fuyu Tsuyama's short story Magical.

Background and release

[edit]

Aniplex first announced an anime adaptation of the manga series Hana-Kimi in May 2024.[1] On September 14, 2025, at Aniplex Online Fest 2025, it was announced that Yoasobi would perform opening and ending themes for the anime series, set to premiere in January 2026.[2][3] On November 8, the songs, alongside their titles—opening theme "Adrena" and ending theme "Baby"—and snippets, were revealed through the anime's promotional video.[4]

On January 1, 2026, Yoasobi announced the release of "Adrena" for the next three days, the same day as the anime's premiere, via digital music and streaming platforms.[5] Its cover artwork, illustrated by Naji Yanagida, features the anime protagonist Mizuki Ashiya.[6] The limited double A-side CD single, alongside "Baby", was released on March 4, additionally containing the English, "anime edit", and instrumental versions of both songs.[7] The English version was included on the duo's English-language EP, E-Side 4 (2026),[8] while the original version on the duo's fourth Japanese-language EP, The Book For, (2026).[9]

Composition and lyrics

[edit]

Fuyu Tsuyama wrote the short story Magical specifically for "Adrena". Published on the Hana-Kimi anime's website on January 3, 2026, it depicts a prequel to Mizuki's feelings for her love interest, Izumi Sano, and her experiences at school since then.[10] Lyrically, the song expresses the protagonist's exhilaration and confusion and "straightforward yet awkward" and unrelenting love, as she pursues her dream boy, driven by "up-tempo pop track with comical sound and dizzying electronic developments".[11][12]

Music video

[edit]

An accompanying music video for "Adrena" premiered on January 6, 2026. Directed by Tsuribu Tokyo, who previously handled Yoasobi's "Players" music video, the comical 3D-animated visual features characters from Hana-Kimi, including the protagonist, Mizuki, who runs, flies, and passes others amid a chaotic atmosphere.[13] The English version's music video was uploaded on April 24.[14]

Live performances

[edit]

Yoasobi debuted the performance of "Adrena" at Pentatonic music festival on January 24, 2026, at Yokohama Buntai.[15] The duo later performed the song at the 2026 Central Music & Entertainment Festival and the Music Stadium in April.[16][17]
