ADAMAS

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 (melody) was handled by Kayoko Kusano. The track's final arrangement and production was executed by Shota Horie.^[1] 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 (who loves it?)/ADAMAS", which followed on December 12, 2018, under the Sacra Music label.^[3]

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" (up-tempo) rock style, contrasting it with the symphonic elements of the accompanying A-side "Akai Wana".^[4] The track is frequently cited as a staple of Lisa's live performances, often grouped with her other high-energy anime themes like "Gurenge".^[5]

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.^[6]
