This is the standalone version of sa×××××××. The cover is identifiable by a group photo of the band. A version with alternate jacket was also included in the band's [Limited Edition] set.

The release date is unknown. However, the [Limited Edition] set uses product numbers U-008C and U-009C, so this standalone demotape was likely released at the same time or just after the set. Given that a Tʌ́-rot tape with U-005T was released in July 2000, both the set and this standalone version must have been released in late 2000. (Note that the letters in these product numbers only indicate the band name, and not multiple types.)
