Description:

Ayla Yuki's 15th single! The lead song "A Promise," which is the ED theme song for the TV anime "The World's Best Assassin, Reincarnated as an Aristocrat in Another World," is a chillwave ballad song that sadly but warmly describes feelings for a loved one under the moonlight. Arranged by Masayuki Hasuo (siraph, ex.School Food Punishment), the song breaks new musical ground for the artist. Two couplings are included. The title track "A Promise" is sung by the heroine Dia (CV: Rena Ueda) in the movie! The song is very much linked to the worldview of the movie and the emotions of the characters, and you can enjoy the differences in the singing on this must-hear disc. Includes a total of 5 tracks, including off-vocal versions of each song. Newly illustrated back jacket.
