The last mini-album in a series of releases celebrating KISAKI's 30th anniversary of band activities. Contains three new songs; a re-recording of the LIN (凛 -THE END OF CORRUPTION WORLD-) song Cross Peagent (which was itself a re-recording of the KISAKI PROJECT song Shou kei (情 景)); a re-recording (with different vocals and additional guitar) of Doppelganger from Afterglow (an earlier album in the 30th anniversary series); and a re-recording (with different lyrics and a different vocal take) of Irreplaceable World from Providence (an earlier album in the 30th anniversary series).

Those who purchased the mini-album through the LORELEI ENTERTAINMENT GROUP web shop received a CD containing instrumental versions of all songs.

The song Mermaid was accidentally included (in a pre-mastering state) on the initial press of the 30th anniversary series album Preuve d'etre.
