Preview CD for the Kuchi zuke (接 吻) mini-album. Details are unconfirmed, but it was likely a CD that was available only at CD rental shops, to encourage people to rent/buy the full mini-album (a common tactic at the time).

The packaging is very plain, and the cover is simply a generic metallic background with a small version of the Kuchi zuke (接 吻) cover art superimposed on top. The CD is thus sometimes referred to simply by Kuchi zuke (接 吻), but it seems more appropriate to refer to it by the two tracks that it actually features.

-> (2024/06/08) Confirmed it is a promotional CD that was available for a limited time, the CD image was found.
