adieu (the music project of actress-singer Moka Kamishiraishi / 上白石萌歌) has been tapped to perform the ending theme for the second cour of the TV anime 「本好きの下剋上 領主の養女」 (Honzuki no Gekokujou: Lord's Adopted Daughter / Ascendance of a Bookworm Season 4). The new song, titled 「Wanna me」, was written and composed by acclaimed singer-songwriter Satoko Shibata (柴田聡子).

The Song

「Wanna me」 is described as a song where adieu gently accompanies the protagonist Myne (now Rosenmein) like a storyteller, supporting her inner strength and individuality. The track was penned and composed by Satoko Shibata, known for her distinctive indie-folk sound and poetic lyricism that has earned her a strong following in the Japanese music scene.

Single Release — July 29

The CD single for 「Wanna me」 will be released on July 29, 2026 in two formats:

  • First Press Limited Edition — includes a Blu-ray featuring adieu's September 2025 live performance 「adieu LIVE 2025 à la plume」 at KT Zepp Yokohama, plus behind-the-scenes making-of footage
  • Limited Period Anime Edition — features anime newly-drawn cover artwork

About the Anime

「Honzuki no Gekokujou」 (Ascendance of a Bookworm) follows Myne, a book-loving woman reincarnated in a medieval fantasy world where books are rare luxuries reserved for nobles. In Lord's Adopted Daughter, Myne — targeted by nobles for her magical power — chooses to become the adopted daughter of a lord to protect her family and friends, taking on the name Rosenmein as she navigates a world where common sense doesn't apply.
