is the first greatest hits album by Japanese singer Ado. It was released digitally via Virgin Music on April 8, 2025, and physically the next day. Announced in early January, the album includes songs from her first and second studio albums, Kyà Âgen (2022) and Zanmu (2024), alongside songs from her soundtrack album ' (2022) and her cover album Ado's Utattemita Album (2023).
Ado released her second studio album Zanmu in July 2024. Similar to her debut album Kyà Âgen (2022), Zanmu debuted at number one on various Japanese charts. Following the end of Ado's Japan tour Mona Lisa Profile, she released her first double A-side single "Sakura Biyori and Time Machine" featuring Vocaloid Hatsune Miku and "Shoka". Within that month, Ado announced her second world tour, the Hibana Tour.
In January 2025, Ado's management team posted a teaser hinting at Ado's 5th anniversary since debuting as an artist. Hours later, her team revealed Ado's first greatest hits album.
Artwork for the album cover was handled by Orihara, who has designed Ado's previous album covers. The standard, limited Kigeki and box set edition each have different cover art.
Released on April 8, 2025, a day earlier than the originally announced release date, six versions of Ado's Best Adobum was announced by Universal Music Japan. The edition includes a Blu-ray or DVD of Ado's debut concert at Zepp DiverCity Tokyo Plaza on April 4, 2022. The limited Deluxe Box Edition combines the "Kigeki" Edition with bonus goods. First press goods for all six of the versions include a trading card while additional bonus goods vary from additional shops. The album is marketed by the slogan "All hits, no misses".
