This was part of a 20-person-limited iced coffee + CD set that was available at the band's one-day limited cafe, STAR★BIRTHDAY Cafe. (STAR★バースデーCafe.). The small malt/milkshake cafe was put together to celebrate the birthday of drummer P.

The first track is an SE. The second, 小沢さん(仮)-盆踊り風remix, contains part of an unreleased song called Love Letter. Only the chorus of the song is untouched; the rest of the track is a remixed version of the song, with the intention that the full version would be included in a mini-album called LOVE★POD. That release was ultimately cancelled due to vocalist shyena★ seceding, and the full version of Love Letter was never released. (Another song that was planned for the mini-album was Love★Peace.)
