This concept (or “comcept”, as it was misspelled on the packaging) single was released by HEISEI ISHIN to test out a new style. Each copy includes 1 random trading card, of 6 possible (one of each member, plus one “special” card).
This edition was advertised as containing both a PV and unspecified “bonus footage” on the DVD (and the packaging advertises this feature as well). However, the DVD actually contains only the PV; there is no bonus footage to be found. Presumably, this was a manufacturing error.
