Apparently sold at the band's 1999-12-25 live, and advertised as their last demotape—though not their last release, as the band was planning to release a CD.

The insert includes lyrics for both 「after」 and F, although the latter song is not actually included in the demotape. The lyric insert makes note that F would be included in “the upcoming maxi-single + VHS set in February.”

The planned CD+VHS set referred to by the lyric sheet was 「MOEBIUS」, which was instead released through Matina in March as a DT. The band had already broken up by that point, as the vocalist joined Syndrome.

Although the demotape itself is named 「after~」, the song is named 「after」 (no tilde).
