The cover art, a tracklist, and a teaser video have been released for vocalist Aira Yuuki’s 15th single “A Promise,” which is also the ending theme song of the anime series The World’s Finest Assassin Gets Reincarnated in Another World as an Aristocrat! The lead song, “A Promise,” is a melancholic yet warm chill-wave ballad that describes the feelings of someone pining for their lover under the moonlight. It was arranged by Masayuki Hasuo (siraph, ex. School Food Punishment) and opens up new frontiers for him musically. This track will be released ahead of the rest of the album this past week across all digital music streaming platforms.

The second track is another version of “A Promise” sung by Dia, the anime’s heroine voiced by Reina Ueda. The lyrics perfectly describe the character’s feelings, so it’s a must-listen for fans of the anime! The third track is “Awkward Love,” which was based on an actual couple. It is a jazzy-pop song that describes a clumsy but innocent pair of lovers.

Samples will be available ahead of the release date, so please check them out along with the track here!
