Eir Aoi Releases New Sword Art Online Movie Theme Song

Anisong singer Eir Aoi released a new single today.

The title track, Heart (Shinzo, in the original Japanese), is the theme song for the upcoming anime film "Sword Art Online the Movie -Progressive- Scherzo of Deep Night", which will be hitting theatres in Japan on October 22nd.

The song’s lyrics, music and arrangement were all handled by n-buna from Yorushika. It's said to feature a "memorable piano intro and a clear guitar rock sound". The track is also said to offer a "refreshing reminder of the confidence that one can 'fly anywhere with you' in the expanding blue sky of one’s youth".

Eir personally stated that the song is quite different from the past "Sword Art Online" theme songs she has sung, and that she is grateful to n-buna for creating the song as a new challenge for her.

The single also includes two coupling songs, titled EVIL and Dance with me, as well as instrumental versions of all three songs, for a total of six tracks.

Heart is available digitally worldwide now, and links to download and stream it on various platforms can be found here. It is also available on CD, in three limited editions featuring various bonuses.

The music video for Heart can be viewed below, followed by a short English-subtitled comment from Eir Aoi about the release.
