The band's first mini-album after going completely independent. It features a special wrap-around jacket (but no back cover) and each copy includes 2 random trading cards (of 8 possible). Each store also had its own privilege photograph for the release.

Initially, this mini-album was to be released through inner dream group (the successor to Soleil), and was to feature new songs + remixed/remastered old songs. There were also plans for a special privilege for purchasing both 37℃ and this mini-album. However, in response to poor management, Birushana (美流沙女) seceded from the company and formed their own label, ViRUS. Due to the management switch, the band was forced to record the entire mini-album in one session-and because the rights to the old song belonged to inner dream group, the band was forced to discard the remix/remaster data and rerecord the song instead. The double-purchase privilege was also cancelled due to the management switch.

In 2009, distribution company BounDEE (now SPACE SHOWER MUSIC Distribution) purchased the rights to the 【kapparecords】 back catalog, and, from 2009-07-29, restarted distribution of all Birushana (美流沙女) releases from the label. It's unclear if second presses were made. The new catalog number for this release is DQC-326.
