The reason is on me. This is a set of the 2nd AL "Kyozou to Jitsuzou" (Illusion and Reality) FC Limited Edition and First Press Limited Edition. Although I have never read it, I have taken it out of the outer bag, so please refrain from purchasing if you are concerned. Please check the back for the tracklist. Includes a DVD Disc of "Kasou Genjibu Kuukan: case.3 Multiverse Interpretation" and a Blu-Ray Disc of "One-Man Live Genjibu Kuukan: case.1".
