Little Glee Monster has announced that they will release a double A-side single featuring the songs "Ichirin" and "Pages" on June 10.

"Ichirin" serves as an insert song for the TBS Sunday drama 'GIFT,' starring Shinichi Tsutsumi, while "Pages" has been selected as the opening theme for the TV anime 'Ascendance of a Bookworm: Adopted Daughter of an Archduke.' In addition to the two title tracks, the single will include two coupling songs.

It will be available in three editions: a regular CD edition, a limited first edition with Blu-ray, and a limited anime edition with Blu-ray. The first limited edition Blu-ray will feature six live performances from the group's 2025 nationwide tour 'Little Glee Monster Live Tour 2025 ~Ambitious~' at Festival Hall in Osaka. Meanwhile, the anime edition Blu-ray will include the non-credit opening video for 'Ascendance of a Bookworm: Adopted Daughter of an Archduke.'
