This is a set of four CDs, EP1-4, by DALLJUB STEP CLUB, released in 2012. I purchased these at a live show and have kept them in storage since then. The cases show some wear and tear due to age, but the discs themselves have no scratches. The drummer of DALLJUB STEP CLUB is currently a member of "Raisan," a band consisting of members from "indigo la End," "Gesuki no Kiwami Otome," "Genie High," and "Lalande" Saaya, including Enon Kawatani.
