J-pop songstress LiSA is collaborating once again with Sword Art Online, contributing a new song called “unlasting” as the ending theme of the upcoming new animated TV series Sword Art Online Alicization War of Underworld.
The latest single will mark the anime/game song singer’s seventh to be featured in the SAO franchise, following her hit song “ADAMAS” that opened the previous Alicization arc.
LiSA describes “ADAMAS” as a tune that expressed “hope for a shining future,” while “unlasting” is a closing track that expresses “hope that the sadness of those left behind won’t last forever.” Watch the trailer below:
The song “unlasting” will begin airing Saturday (Oct. 12) from the first episode of the new series, and will be released in digital form Oct. 21. Pre-orders began on Monday (Oct. 7), which is the birthday of the protagonist Kirito.
