The album peaked at number 19 on its first week on the Oricon Albums Chart and remained on the charts for seven weeks, selling 7,080 units.

The fan club edition housed every promotional single since her debut, while the standard edition contained her most popular singles from each album. The DVD held each of her most popular music videos, while the three Blu-rays carried every music video since 2000. The Blu-ray also featured the three music videos from Fever: Legend Live, which Koda Kumi had released during the promotional campaign for SANKYO's pachinko game, Fever Legend in 2014.

The album was preceded by the extended play Angel + Monster. However, the music videos for "Killer Monster" and "Run" were both omitted from the standard DVD and the limited Blu-ray.

There were several songs omitted from both the 8CD and 3CD editions, despite being released as A-sides throughout her career.

None of the songs from her cover albums Eternity: Love & Songs (2010) and Color the Cover (2013) were included in the set.

To help promote the album, Kumi released a "Best ~2000–2020~" version of her 2004 song "Cutie Honey" on October 25, 2021.
