Development and release
The production of "ADAMAS" involved a collaborative development structure where the work was distributed among key individuals: the lyrics were written by Lisa herself, while the primary musical composition was handled by Kayoko Kusano. The track's final arrangement and production was executed by Shota Horie. The recording sessions for the track took place in 2018 in conjunction with its planned use as the first opening theme for the anime series Sword Art Online: Alicization. The song was initially released to the public in a digital format on October 8, 2018, before being issued physically as part of Lisa's 14th double A-side single, "Akai Wana /ADAMAS", which followed on December 12, 2018, under the Sacra Music label.Reception
Music critics and publications have praised "ADAMAS" for its aggressive rock sound and compatibility with the Sword Art Online franchise. In a review for the Japanese music portal Skream!, the track was described as a "killer tune" that highlights Lisa's vocal power and the "symbiosis" between her music and the anime series she frequently represents. The review noted the song's "upper" rock style, contrasting it with the symphonic elements of the accompanying A-side "Akai Wana". The track is frequently cited as a staple of Lisa's live performances, often grouped with her other high-energy anime themes like "Gurenge".A concert review published by the online music magazine KpopWise analyzed the track's musical role within a live performance setting. The reviewer noted that "ADAMAS" provided a structural contrast to the slower, more emotional ballads in the setlist, serving as a key component of the performance’s high-energy, driving rock segments.
